Hi it is RJ... I know nothing about planes. I live in Auburndale. This is so cool. The videos are great. I'm a Vet at 72 soon. I wished that I could have got into planes. Back in the 90s a friend was showing me about them. Sometimes I think I'm flying. I watch's all that you do on the planes. It is cool to watch. Thank you.
Little bit of history’s from WW2, concerning the Supermarine Spitfire. Mushroom-head rivets are far less labour intensive than countersunk, but the countersunk are better in terms of drag. They want to have the Spitfire as slippery and fast as possible but with regards to speed of assembly. So, they made an all-countersunk Spitfire and then glued split peas of the countersunk rivets, in various positions and patterns, until they came up with a good balance between the mushroom headed and countersunk, in terms of speed of the aircraft and ease/speed of assembly. Aren’t people amazing?
Thankx fer da Histoey lesson . Now o gotta go look up mushroom rivets Thankx
People are amzing. But, on the other hand, not so much.
@@PatriotCanadian they are domed rivets never heard them called mushroom rivets before
Nothing better than a cup of coffee and watching Jimmy work on a airplane. Always looking for the next video to come out.
I was working on my RV 4 one day( installing new baffles on the engine) , Herb Colbert came by and was looking at the insulation he said you're doing a good job there, but, when herb Culver says but I pay attention ! He sketched out a little baffle assembly to help clean up the air coming out of the engine cowling on the bottom, we picked up an average of five knots across the board I made it quick install/ removable so we could test performance. Herve Colver was the lead aerodynamicist at Lockheed skunkworks working beside Kelly Johnson .
Hiya Jimmy - years ago Sun n Fun sponsored a race from some airport in GA to Bartow Florida. I entered the race with my Super Cub in the 150 HP Class. Us 3 cubs and a T-Cart has lots of competition including RV-4s with O-320's.. But...I wanted to make a good showing with my cub so I sealed all the gaps - it took a lot of tape.
I don't believe I got much speed increase, but the fuel burn improved by more than 10%.
Some of the Reno sport class guys have done in depth speed mods for the Lancair. A cowling redesign would probably get you 5-7 knots.
Dont send him a message on Telegram. Its a scam-bot.
The most efficient planes in the air are sailplanes. Hold that thought.
Things sailplanes do (gliders) to make them more efficient are:
- use mylar tape tape on the seals
- divert the exiting air from cockpit to a single spot (often at the base of the rudder)
- seal up the air going from the cockpit into the wings (this one seal makes a significant difference)...having air exit at the ailerons = no bueno
Those are all that come to mind.
What do you mean efficient? You mean impractical and unable to stay in the air without sun or winds for lift. Ha ha. I think you confuse efficiency with glide ratio and low drag. Yes they generally have better glide ratio and lower drag than powered planes. However there are powered planes that are very efficient, think of them as powered gliders. However an engine sticking out, higher aircraft weight causes loss of efficiency. Back to first 2 sentences above. You can't take 250 people from New York to Paris in 7 hours in a glider. Definition of efficient is vauge. Do you want to go to war in a F-22 or a glider.
and tape a piece of Yarn to the canopy windshield. very important yaw indicator.
Lol i thought the same thing, that glider has infinite efficiency based on his definition lol.
They are efficient, but they are for sports, not practicallity. That's what touring motor gliders are for. And it is true, that you can make a powered aircraft more efficient by adding well proven things from gliders.
Howard Hughes called, he wants his mustache back! Another great one in the can
That prop blade angle on Cameron looks pretty aggressive, if it's a ground adjustable and you have some wiggle room with the max engine RPM you should maybe try and decrease the blade angle to have more of a 'climb prop' than a 'cruise prop' for this competition. Fine wire spark plugs, solid state sparky boys and trying to lean for best power at wide open throttle frequently could make it competitive with the 401. Always love these videos, great stuff Jimmy! 👍👍
Considering how fast a lancair cruise it, it make sense the prop has a high pitch angle. A fixed pitch climb prop may lose a lot of cruise performance comparing to how much a cessna may lose with a climb prop...
@@shiroyukiwang1252 He can always adjust it back to what it was once he smokes all the competition! Lol
The prop blade angle is not constant. They are variable pitch props, with pitch adjusted in flight, as is throttle, to give a combination of RPM and Boost Pressure. Fixed pitch props are more usually used in initial trainer aircraft.
@@alantorrance6153 It's a fixed pitch or ground-adjustable prop. No prop lever.
For future reference: if you have to peel off sticky tape from painted surfaces make one end loose, fold it over and peel it parallel to the surface. Also most of glues on those tapes are weakening with heat, so a quick pass with heat gun will help loose it some more.
Invest in goo gone.. We used it at a recertification facility i worked at and its amazing.. Done deal..
Using nail polish remover along the peel back works better than a heat gun.
@@2muchcowgirl155 Wouldn't that remove the paint also?
Yep.
@@johnnunn8688 you can use regular ole gasoline if the paint is an issue.
We were told never to blow in the pitot tube because it could damage the instrument or knock it out of calibration. The line behind the instrument should be disconnected first then blown out to remove obstruction.
That sounds very sensible as the ASI must be a delicate instrument
Jimmy, you should put a gear locked annunciator in the Lancair. I put one in mine, and it makes it easy to know when the gear is locked in position. In addition to the three green for down, it is a backup indicator for all three down and locked as well as when the gear is properly up, which is handy since our gear is only held in place by pressure.
Jimmy for future reference you should drill your holes in the trailing edge of all of your control surfaces so that in flight they drain if there is water and sitting on the ground when it rains they drain. You should make that happen. Your should also do an extensive check of your control surfaces to make sure you dont have any issues from the standing water.
Water in the ailerons is quite dangerous, they are counter-weighted against the occurrence of flutter and with any amount of water inside, the counterweights are no longer balanced and heavy enough to stop flutter. You had likely doubled the weight of the ailerons with all that water inside them. At higher speeds a serious hazard and catastrophic loss of both the ailerons was quite likely.
How does your son film without continuously laughing at you?
So how would he keep the water out of them?
@@twistedyogert He probably just needs to remove and waterproof all the connecting hardware.
@@twistedyogert small vent holes in the right places, low points. Must have small vent holes to prevent the air trapped inside from expanding at altitude and they blow up from internal pressure. My Glasair has similar ailerons with small vent holes, not sure how he gets a quart or more water inside.
Jimmy you need to use acetone to clean your wing before tape. Achilles leaves a little oil and check out how to grease wheel bearings and there’s 2 ways one in your hand or buy a bearing greaser but I have used my hand to pack the grease till it comes out all the way around . You can race my Glass air 111 it goes 300 on a hood day and like yours uses very little fuel .
We use to use a tape we called 200 MPH tape. Didn't work that well since many of our planes were faster, up to 0.87 mach...We had a 310, an Aztec, some Navahos, Metroliners and a Lear 24B...
Jimmy, you are one entertaining guy. I enjoy your channel very much. You are a hoot.
Important lesson for everyone, drain holes! Also pressure relief if areas are well sealed and the plane is flown at high altitude. Check Eliot’s video on the Thunder Mustang horizon tail cracks….
I get alot goofy grins watching your channel Jimmy! 193, it's a good thing that the Lancair took a wee before the race.
Jimmy, you forgot to deburr drilled holes 🤣🤣
The Apache will always have a special place in my heart. Did a lot of my training in one
Wash and a good wax will help, we sometimes has to re-trim our j-57s after buffing out the ring cowl of my nkc-135a (white top) AWATFP 55th OMS rocks
Is everything you do is full of awesomeness I have watched every video you have me at least twice and they always make me laugh and I always learn something keep up the good work you guys make my day
Lol I was going to suggest glider mylar and tape. It's an art, and it's easy to make a buzz if you get it wrong. And that's in a 130 knot glider. Half way through the video, so don't know if there's buzzing yet for your handiwork...
Haha that gear flap down will easily negate any gap sealing advantages... Hope you fixed that before ripping off all the mylar :)
Jimmy always a enjoyment and never a let down watching one of your Videos 👍
What made the wheel door not go up on the plane?
That was fun! Watching Cameron zoom past was the bomb!!
Man, that rear chock was like "nope, I've seen this one, byeeeeee... Damn, I'm tethered. NOOOOOOOOO!!!!!!"
The bug in the pitot tube man you threw away good protein probably was more protein in that than the fancy mexican restaurant you showed in the background at the end of the video. Man you do eat at the best places LOL.
absolutely awesome great job jimmy can't wait to see the speeds with the better magnetos
Back in the day I was an A10 Avionics troop. Bugs in the pitot tube was a common culprit for airspeed issues. Invest in a small piece of clear tubing and a reducer for your shop vac so you're not eating bug guts!
All Formula 1 teams use tape to cover the panel joins on their cars. If they think it's worthwhile, then it's a no-brainer that it's effective.
Still waiting to see more MiG and T6 action Jimmy 💪🏻💪🏻💪🏻 Cameron doesn’t stand a chance against the T6
Did not like hearing both pilots say they don’t know where each other are at during the climb.
i think i heard jimmy say they have some magical GPS thing called ACAS/TCAS
Turn your gauge over for measuring the gaps Jimmy.
Jimmy’s World 🌎 is the idiots guide to airplanes. I LOVE ❤️ Jimmy’s World! What could possibly go wrong?!?
Tough to make that Lancair into a dragster with the gear door open....but, impressive climb Jimmy!!!
Probably because it's so light. I don't know what Cameron is made of but it looks like some kind of composite.
@@twistedyogert Honeycomb prepeg
Great video! Wait, why does that water smell like fuel? 😲
Gotta love “Experimental” designations. So much more room for fun and frivolity
During glider races we tape off everything even our canopy. The trick is to slightly pull the tape while you apply it.
If you outland on a very hot day, and no one is right by you, how do you remove the tape to be able to open the canopy? Sounds like a miserable exit from this mortal coil to me.
Great modification Jim. Hope it works, and wear silicone glove handling tape, no finger organic contamination.
I bet jimmy will win that plane would beet the twin cessna I can't what to see the 310 come together soon that was a cool race Jimmy!
Jimmy, if you haven't already done something about the tape interference around the canopy, take the Wife's Blow dryer on high heat or a heat gun on low heat and carefully heat it till you soften and direct the tape to stand off the mating surfaces enough and cool to clear the problem areas!
Jimmy far be it for me to tell you something but the pedo tube aka air speed pressure tube can’t take a lot of air pressure when you test them you use a syringe and only use small amounts of air with you blowing into it it’s a possible you damaged the diagram in the airspeed indicator and that’s why your top speed was off and when you took off it looked as if you was just above stall speed but that’s my two cents it was fun to watch best wishes
All you need to do is rent a Yukon Denali from Avis and you have all these airplanes beat. One Avis customer did 22,000 miles in 68 hours averaging 333 mph. True story, Avis even charged the customer extra for the privilege of driving such a fast car.
It a good thing you go the water out of the aileron as the water will cause a serious flight control imbalance and thus flutter at higher speeds.
Time for the Mike Patey BTU Upgrade
373 - 383 cruise speed
8000 foot per minute climb rate @180 knots. Love the channel
Really nice vid to look at. Jimmy you are the best and most funny pilot i ever listening on haha soooo nice vid thanks so mutch.
Lets do it!!!! Def want to see that race!
The Lancair sounds like a ground-loop on the P-lead.
Jimmy, make sure your gear doors are sealed “in flight”!
Love the Ex Perimental
The timing on these aircraft starts always seems a bit too advanced since the prop often kicks back which is hard on starters and flywheels. I’m sure you know all this. Btw I love your enthusiasm!
Thank you for the video Jimmy.
JIMMY MY BOY I do believe you to be much brighter than you make out to be...
I owned and flew a PA23-160 Apache and setting 2450 RPM was a MISTAKE... He should have been at 2700 RPM and full throttle. The more RPM the more HP the more climb.... Also the Apache holds about 108 Gal of fuel.... How much fuel did he have in it. Solo light fuel the Apache performs well.
No the plane isn't going any faster...its your bank account :)
Jimmy your always bloody breaking things hahaha!
Waiting for the magnetos ...should be a LyNOTcoming t-shirt
Congrats Jimmy on ur win racing the piper. like the views..
Wonder what speed penalty you got from the open gear door? And I wonder why it didn't shear off at 193 knots.
I am having the same problem with my car. I want to go 200 mph at Bonneville Speed Week and join the Red Hat Club.
I can now regularly get 196 but it took a metric buttload of work and money to get from 180 to 190 and then its been getting exponentially more resource intensive to gain an additional MPH for the last 6 miles per hour.....
At this rate, I will completely run out of money, time, food and will have used up a lifetime of collecting favors to get to 199 and then I will have to quit.
Been thinking about selling t shirts that say, "Just 1 More".....
Cubic dollars as they say. I wish you all the best in the pursuit of speed good sir!
What car
@@jonasbaine3538 1988 Porsche 928 S4
Seal the cab. If there's any air movement inside, that means somewhere in the body there's a gap catching air. T-6's at Reno can see several mph gains by making sure the canopy and whatnot is sealed up, and they're flying in roughly the same speed regime. Unless you're power limited, it's all aero at this point.
@Skinflaps_Meatslapper I'm on it already. The car has a aerodynamic skid on the bottom of it. I removed the mirrors and taped all the gaps in the body. The car is pretty well sealed from the factory. Something my wife just can't seem to remember. In winter she has to pull on the door pretty hard to get it closed.
During summer, if I have any window or the sunroof open even a tiny crack she SLAMS the door soooooo hard....
I had it on the freeway once at sunrise with the whole road to myself coming down out of the hills on I-5 descending down onto the valley floor.....
I slowly pushed the pedal down and let the car accelerate all the way to 160 mph before I got nervous.
I took my foot off the gas and was amazed at how long the car was taking to slow down.
I had turned off the a/c and it was a little warm in the car so I decided to crack open the sunroof and the pressure dropped and my ears felt it instantaneously.
And the car started to slow down like I threw an anchor and chain out the back as I lowered both door windows.
I have to say though, that car sucks down to the road like crazy at those speeds.
I'd like to try a hill climb event. With the handling and the horsepower, climbing a hill would be a great way to race that car.
Jimmy, I think that Cameron needs a trip to Sweden for some radical changes to turn it into a Glasair III with a turbo 6.
I have used soaring tape for years on my Debonair, sealing the wing root rubbers on the bottom sides of the wings. Installed flap and aileron gap seals years ago too. then did a very accurate rigging of the flaps and flight controls. It accounted for 8 kts difference in cruise and 200 ft/min climb rate increase, so you will see improvements.
After seeing the water coming out of the ailerons, I had to stop the video and comment. The concern I have after seeing the water leaking out from drilled holes in the ailerons is flutter. With all that moisture in there I can't imagine your flight controls are balanced. Another point along those lines is the tape coming up from the seal around the flight controls. Steve Wittman died as a result of fabric separating (a bubble in front of an aileron) creating an aerodynamic imbalance which started a high speed flutter.
The point is the faster you go the more critical the balance of the flight controls have to be. And a home built aircraft, built by someone else, needs to be carefully examined and checked.
Anyhow, back to the video.
w
Flutter from unbalanced control surfaces is certainly an issue with faster homebuilts, and while it's not good to have water in control surfaces throwing off balance, I doubt it would contribute to flutter unless the entire thing was completely filled. Sloshing water would act as a fluid damper and if anything, it would have the opposite effect. The mass of a surface has to be elastic in order to experience aeroelasticity, so that means the weight needs to be relatively stiff and at least fixed to the surface.
@@Skinflaps_Meatslapper once it freezes at altitude it is not a damper. Especially far behind the hinge line.
Jimmy, you need to fly knife edge 15 minutes on each side to drain the wings....
I can't believe he drained the aileron damping fluid.😲😮😂🤣
Nah, it is the toilet overflow tank!
22:04 looking suspiciously like the unibomber sketch there
Jimmy did you go to Mission Barbecue with your son? I love Mission Barbecue!!!! I love the fact that they not only have great food but they also stop everything to play the National Anthem at noon everyday. Would treat you out if you ever get up to Jacksonville FL. Give me a shout.
Water in the ailerons... is that a typical nuance with the Lancair?
there goes the lance air's tip tanks :)
Of course it will start! It’s a lycoming!
Don't tell me you ate the twizlers, that was made for when you havea leak on the go then you pu a string of that off to make a homemade o ring to get you back 🤣🤣🤣
There’s zero grease on the bearing I would worry more about that than breaks you maybe making a unscheduled left turn
You will notice Jimmy greased it ( them) up on reinstalling the wheel. Also what a crappy design on the brakes that the piston popped out. No rubber piston dust seal like on a car disc brake calliper.
That was such a cool sight when you blew past Mike @ 193 knots, Jimmy...
Jimmy, i would pull the ailerons, and check for internal corrosion, unless those are fiberglass, also you should drill at the lowest point for a drain, just my 2 cents.....Retired Navy Airframe tech.... Fly Navy
Honestly that work is not only an embarrassing mess, it's scary dangerous. Tight gaps freeze up more readily . It's a compromise and those appear tight maybe it's the camera .
I don't know.
Hey Jimmy, love your videos. But, with all your resources, have you ever thought about seeing an orthodontist?
You cheeky bastard!
Nice Tape Job Jimmy 🤣🤣🤣
wonder how many times you tan the car battery down in the car leaving the doors open for hours while filming this?
Thrust required to go faster is the square of the airspeed increase (2X speed requires 4X moe thrust).
Just as I tip. I do believe, IIRC , that when the F15 did the time/height record, many years ago, it accelerated the climbed, then dived (dove?) to accel, then climbed again etc.
Jimmy. You need to be very careful when changing gaps and clearances on Airplane control surfaces. Doing the wrong thing can create 'Flutter' which is deadly to an airframe. Check with the original owner to see if He had a test done for control surface flutter at different speeds or check the airframe manufacturer to see what they have on gaps and clearances vs airspeed.
He was doing wing joint (fixed) and flap (also fixed except take off and landing. I think he did something on inboard end. Not a big deal. However you are correct doing an aileron seal or elevator seal can change feel or effectiveness.
4 ways to slow your Plane down. 1: drill two holes to let the ballast water out 2: put sticky tape on to hold it tight 3: leave the bomb bay doors open 4: add new brake shoes for even more stopping power and ohh yeah suck a bug for good measure 🦟 GO Jimmy
I remember the time my dad showed me my first hammerhead in a old N3N-3 like 20 yrs ago. I think atleast 5-10 gallons came out of those ailerons lol Tasted like river water and piss!
You need some flames painted on that plane !!!!!!
If he doesn’t watch out one day he’ll have real ones I’m afraid. I have him on a prayer chain.😂😂😁
That's why you need a pitot tube cover when tied down outside.
Glider pilots love smooth surfaces, lots of tape and gap seals everywhere! But better be careful with that gap seals! A test pilot friend once told me this story: He was hired to do initial flight testing on a certain single engine piston kit plane. The builder came from the gliding background and added gap seals on the elevator that were not in the kit plans. During flight test it was noted that the flight characteristics went from "okay" to "not acceptable, happy to be on the ground again."
You are too funny at 10:15 when you say that tape on one wing is worth one knot and the other side will be worth 2 knots. 👍👍🥜🥜
Everything is appropriate on Jimmy's world !!!!!! Let's line up that beautiful 310 for the climb race !!! Blue skies !
Jimmy, have you forgotten what you said about having to add another wire for the second mag on the new lycoming mags so they would run together
Hi :) Maybe i´m wrong, but at 13:00 i can see, your aileron is slightly bent... Even better visible, when you move it up and down. It´s not much, but it´s not 100% straight.
Check the speedometer cable
🤣
I commented the same on a previous video that if you could find someone with a Beech Stagger Wing it would be a cool and good looking race !
That video ending was Funny. I laughed pretty good...Taco Bell...Thanks Jimmy. Follow your Excitement 🛩
Thank-you for your content.
You are so chill. I would've freaked out pulling the paint of the wing
Great video Jimmy a lot fun to watch. I guess you know now your landing g gear door was down. Few mph id say. Thanks for posting I enjoyed
Jimmy: I would use Kapton tape to seal gaps, its very slippery, comes in the widths you need.
Landing gear in general seems to be Jimmy's achiles heel.
That added weight and complexity and high insurance (consideration for gear up landings) is the reason so many General Aviation aircraft owners stick to fixed gear aircraft. 😙
Great stuff 👏
@6:20 I am sworn to secrecy. "I knooooooow noth-zing"
