WAR Corsair Tail View Taxi Test
Вставка
- Опубліковано 2 жов 2024
- Made three runs tonight to test new vibration mount for the camera and to get the tail up again. Tried to record on the second pass but the camera only recorded 5 seconds. This was my third pass, first with the camera on the tail.
The tailwheel noise is quite evident on this run in the camera.
You can tell when the tail comes up, just from the tailwheel sound going away. Still tough to see the pitch change, but I could see it. The video looked better than I thought it would as far as the drifting to the right after the tail lifted. It felt worse, but it wasn't that bad. This run probably had a little right rear tailwind.
I rebuilt a Taildragger Sonerai II. Did about half a dozen slow speed taxi’s to check brakes and get feel for the amount of rudder needed to steer it. Next was three or four runs with enough speed to get the tail up, then reduce power and let tail come back down, that showed me if I had to abort tack off I had to be ready to quickly apply rudder to compensate for the quick reduction of engine/prop thrust. If throttle was reduced over four to five seconds then rudder correction was less critical. Next was pick a day with little wind, check everything and then fly it. So tail up at 45-50 rotate at 70 and fly. A few laps around the field to determine if trim adjustments needed, they were, and then set up for landing. Carried a little extra speed and successfully landed. Mouth was a little dry but the celebratory beer fixed it
That's pretty much what I am trying to do here. Get the tail up and level, but keep the speed low to keep it grounded. That may not happen that way, but I am ready if it does want to lift. I have started to come down to the airport later in the day to try and get calmer winds. This day it was calmer but a direct crosswind. I'm still looking at ways to help keep it straight on these test.
Go get some training before you wad this thing up and get hurt.
Don, it’s great that you are taking time to feel it out and gain more seat time, but I feel that you are playing with fire by doing high speed taxi test unless you are ready to get airborne. You are flirting with flight, high speeds like that in the three point attitude are a recipe for accidental flight. Either push forward and get the tail up or don’t taxi so fast. I fear that you may accidentally get airborne and either stall or throttle back and land hard. If you are going fast taxing and it gets squirrely, sometimes the safest thing to do is get it airborne to “save” it. Are you ready for that? Congrats on keeping it on the runway, I hope for the best!
With 55 years of tail dragger experience I fully agree with you
Getting the tail full up is the goal right now. That's why I was giving it more forward stick this go around. I can tell that it is more sensitive to speed with the tail low. I also know if I try to go much faster, it will want to lift off. I am always thinking about that. If it comes off, I will fly it and not try to put it down. I would most likely not have enough runway to stop. I'm very close to getting it level. The 90 degree crosswind doesn't help either. Plus that pass may have had a little downwind to it. I wanted to see if it was any better than the other way. The winds were @ 6 mph out of the north. So it was a horse a piece.
From watching these videos for a long time now and not seeing any flying videos or tailwheel training I am questioning if he is even rated to fly this thing.
I totally agree with you Tom, Well said, and very politely put.
I like the use of the word flirting.
Wind sock looked pretty limp.
You got this Don! Can’t wait to see that beauty in the sky.
i think we're all anxiously awaiting first flight as much as you are. 😉
I'm getting excited too.
Fast taxi with tail just barely off the runway is a risky maneuver. Throttling up to 'wheel landing' speeds with tail up in cleaner air gives *much* better directional control, plus it allows you to practice your 'taildragger rudder dance' skills. As a bonus, your forward vision improves greatly. Thanks for the update.
That's what I'm working up to right now. I want to get the plane to a level attitude. If I get it going much faster, I risk lifting off. I want to get a few runs in at tail full up before lift off.
@@Dynodon64 Old timers here told me if it felt good tail high/in regular flight attitude, to go ahead and climb at best rate of climb (+ 5 to 10 MPH safety buffer) to pattern altitude and do a few pattern circuits. Their logic was that if things go wrong, altitude is preferable to impacting terrain doing fast taxi or similar near the ground. They talked me out of crow hops like it said to do in an old FAA first flight for amateur builts publication I had. Your plane is solid, well constructed, and if you're pre-flighted ,fueled, mag checked, and pre-takeoff checklist done, A plan A, B, and C for the maiden flight, maybe that tail up could be your maiden flight...or not. I think you'll know when it is on only the mains. I did, and after 3 laps around the pattern, I headed directly out to local farmland and practiced stalls at 4000', then flying home.
Do you have your prop pitched to achieve optimal power on climb-out? I was super glad I did that. During first flight my air speed indicator quit, and I used the tachometer to estimate speed.
@@Robnord1 I follow your logic here, and that's pretty much sums up what I am trying to do. Once it is airborne, I need to do some stalls to calculate my approach speeds to landing. With and without flaps. The flaps also need to be tested slowly. They are an untested design. My main concern after takeoff is engine cooling. Will it have enough at higher power settings for an extended period of time. As for crow hops, I was hoping to try some, but may not have enough runway for them, with the slow takeoff runs to get up to speed. If I can accelerate at a faster rate, than maybe. Time will tell. It may just come down to power up and go if it stays on track. And yes, altitude is your friend.
I heard the tail rise up. Baby steps are better than no steps written on the landing flaps.😂 Think Sugar Glider, Don! Not Squirrel.
What a view! And you can hear the tail come off the ground
Take your time when you’re ready. We’ll see it fly.
👍👍 You're nearly there Don. Keep building that confidence for the takeoff. Amazing how you can hear the tailwheel getting light around 2:30 into the video then lifting off. Looking forward to congratulating you on your first flight. Good luck buddy! And LOL from the camera tail view it really does look like you're wearing that little Corsair! Haha!
Thanks as always.
Get that stick all the way forward and hold it there until the tail comes up, then adjust it from there. Barreling down the runway in the 3 point attitude is just asking to get airborne. I think it's time you seriously consider some tailwheel instruction. I can tell you no experienced instructor will ever endorse your current testing method. Take all this with a grain of salt, but understand that I've been following you for a long time, and I'd hate to see you have a mishap after all this work.
From the camera placement it was hard to tell if the tail was flying. The pitot tube mount gave a better advantage in my opinion. I’ll have to go back in your videos to see what/how you fashioned the tailwheel. It was plain to see the crosswind pushed you off the centerline.
I received my tailwheel endorsement 30 years ago in a 1941 Taylorcraft L-2 survivor. I remember how hard it was to keep centerline with even a 4-6 knot crosswind during my first solo takeoff so I imagine how hard to was with your light aircraft. Keep working it.
You could tell when the tail lifted just by the sound. The tailwheel noise stops. It was only up for about 6 seconds this time. Had to slow down due to the drifting to the right. I wasn't happy with the crosswind, so I didn't want to push it.
Awesome view 😊
Just seen your video haven't been watching them lately but your getting a lot better getting the tail up Good job
You could definitely tell when the tail wheel was off the runway, be mindful that at the right speed the plane will takeoff in a three point attitude vs having the tail up . my instructor had me takeoff in a three point and also t/o with full flaps and would cover airspeed so you would develop a sense of speed. you have done an awesome job building this plane.
keep up the great practice runs, put the camera on a tripod beside runway and off the tail, nice video but looks like a big thing on tail. again I think you are doing very well .
Thank you.
Maybe you might consider some time with a Instructor with a tail wheel rating to not the rust off.
Would leaving the flaps down help you enter/exit the aircraft? @2:38... she got a bit squirrely! I was not expecting a righthand deflection. As you said later in the video, it's something you have to get used to; which means hours and hours of more taxi tests.
Entering the plane is not a problem as is. The engine torque is what was helping the right drift, and some of the crosswind too. This prop turns the opposite of conventional aircraft, so left rudder is needed on takeoff and not right.
It's a scam! He's done flown it! He is doing this for fun after the comments about him scared to fly it. Guarantee it's a scam
Best camera angle yet! If your new camera has image stabilization, that might be worth a try. Also, even the cheap GoPro clones (I use those myself) should have a battery that lasts for about an hour, so you could just start recording before you start your first taxi run, and then stop recording after you have done a few runs, and then cut/edit the video later, removing the non-interesting parts. Would save you from jumping in and out of the plane just for pressing the record button. 🙂
This camera doesn't have stabilizing. It will record up to @ 2 hours. Don't know how the clip these videos yet, or if I have software to even do it. Time will tell.
V1 Vr V2 and takeoff/landing distance numbers? (Nice DIY camera mount!)
There are no published data for any of those numbers.
Have you balanced the plane with you in it? Are you current in a tail dragged?
Yes the weight and balance was checked with me in it.
I Love this view
I would have to at least tried to crow hop this thing by now and I'm not even a pilot!
That was the plan, but it may not be do able. A longer runway may be needed.
Just about the time the tail came up started to fly start to get a little squirrely that's about the time you have to power through it whenever you get ready
I'm sure full power will help out a lot, or make it worse. Any faster and I'm sure it will lift off on me. I'm trying to get it at a speed to keep the tail up and keep it going straight.
Great video angle. I loved it. I bought a cheap remote MIKE somewhere and that would eliminate wind noise which there wasn't much and then we could hear you and the airplane from the cockpit that way ,take your time you build a beautiful machine with patience and that will keep you alive don't pay attention to complainers pushing you into moving beyond your comfort level. machoism is a bad attitude.
"they are old pilots, and there are bold pilots, but there are no old bold pilots" it has been said
I'm not sure if there is a way to add a remote mic to this camera. It would help though.
Got to edit in the opening scramble scenes form Baa Baa Black Sheep.
What I saw agrees with your comments precisely. I was on the edge of my seat when the plane went right. Well done!
🙌🏼🙌🏼🙌🏼way to go Don 😎💯
May you have wind right down the the runway for TO. FAIR WINDS DON. Your getting there ✈️
Keep up the good work !! Anxiously waiting for the day this warbird is airborne !!
Good video, you might lower the camera view slightly to see the aft part of the cranked wing. Not much vibration or noise. On You-Tube there are several good B+W army training films on how to fly the P-47, S turning on the ground is demonstrated, mild S turns here might be a good habit to get into. Develop muscle memory on the rudder to counter gusts and crosswinds. See what the limits might be as you build more time with it. Best regards for the 4th of July holiday.
Thanks, I'm working on it, and will keep at it to get the muscle memory.
Don, I thought I commented the other day but I guess I didn't actually post it. I think you should screenshot the beginning of this video and use as your profile picture. The plane looks awesome with the sun at that angle!
Hey Don have you done a full CG on the corsair i fly a giant.scale an the corsair is a pain to get the cg right.with gear retracted witch rotates an goes to.the leading edge an makes it even more tail heavy. How did you cg your corsair if you have or havent cg the corsair love to hear how you did the Cg on the home built.corsair i watched your full build vids they where awsome about close to when i built my 93" ziroli corsair. Love to hear back from you how you did the cg check on the corsair. An how you did it.
Happy 4th and be safe from down here in Mississippi just south of Elvis. I do my best to keep the purple tails at FedEx safe and compliant. I'll be up in the area near you the first part of August, I'm from Mercer and my sister and bother in-law live in Sandy Lake. If it works out I might visit the Meadville airport then.
Let me know ahead of time, and I'll see if I can meet up with you.
Hi Don I recently completed a one off homebuilt about the same size as yours and found myself unconsciously making excuses not to fly it anything from I feel off today or wind not just right ect but once I realized it that helped me alot. I always felt so down when i got home and didn't fly it and as Chris Hintz said high speed taxi test don't really tell you much they just put you behind the curve so with that I did fly it and had a few problems that taxi test wouldn't have caught mostly trim and cooling but I did ok and that first flight was a thrill indeed so good luck to you
Ok brother it’s been awhile since I’ve been watching this vid I see no flights as of 7/2/2024. Now I don’t know how much more I can take of this taxing. We need to get this Corsair in the air!
It takes what it takes, I am going at my pace and not anyone else's. Sorry if it doesn't please you.
@@Dynodon64 Your absolutely right SNAIL PACE!
When are you planning to to actually get airborne? By this I mean an actual flight, not my gear lifted off for 3 seconds. Is there a mapped out schedule you are following?
Fantastic view, and filmed in the 'golden hour'. Marvellous.
It would have been better without the 90 degree crosswind.
Don you’re not going to want to force that tail off the ground like it’s a cub. That corsair is a difrent animal.
This isn't a Corsair, It's a sport plane that looks like a Corsair. But I understand your comment.
@@Dynodon64 yes sir I know I’ve flown what you have there
Are you going to fly it?
Why do you think I'm out here every week doing this, if I never intend on flying it. If I just want to run around on the ground, I'll build a Go Cart.
Tail wheel looks like it's tracking good. How's it feel?
Want me to fly it for you? I've never flown a plane, but I will.
Hey Don whats your eta on test flight you think or shooting for.
Don, for what it is worth, I use an external (to the camera) power pack for the GoPro. That way I don't have to worry about turning the camera on and off, or the batteries running low.
I have a remote button for it, but for some reason it stopped. Might have bumped the button and turned it back off. I'll keep trying it.
I agree with @Thomas it is an airplane and the danger now is on the ground ,have faith in your build ,I love it and I for one will give my prayers for your safety in that beautiful plane
Thanks, and I'm not pushing my luck with it. I'm being very careful with it. Some seem to think I'm too careful.
That was great, thanks Don!
Don, I just read in some other comments this video that you still may not have taildragger dual time. Is that true? If so, I'd stop even taxi testing. All of it. Gyro time doesn't count. If a throttle cable sticks or some other whacky event occurs, you're going flying, ready or not, and you'll want some solid stick and rudder time behind you. I took 6 hrs dual in various ultralight trainers plus 6 hrs in an Aeronca Champ. I had several surprises on my initial flight, but the training helped me easily overcome and get her down soft and safe.
I appreciate the comments and concerns, but I will keep on doing what I am doing for now.
Doing great
I felt like I was with you this time! What is the take-off speed?
Don't know yet.
Awesome
Well done again on the ground test, the tail position was more for an in flight type of footage, the pitot tube mount is better for sighting the flying tail shots : )
I'll try to get the wing view recording of the tail lift on the next go around.
@@Dynodon64 I am sure everybody following your construction and ground testing of the plane are greatful for all your output and the filming work, going "stick forward" to fly the tail section at this point in testing, had my heart in my mouth ! Maybe a small amount of flaps can help rotate the main wing and lower ground speed running of the maneuver ? : )
@@peterpatten5043 I need to test the flaps once it is flying. They are untested, so I will test them in small increments at a time, once airborne. Small amount of flaps can help with short field take offs, but that will come in future testing.
To me it looked like it started to fly.
Not quite yet, but I'm sure it's getting close.
Think I’d change out the tail wheel tire lot of noise/vibration.
It doesn't bother me, but it sure does make for some camera noise. I'll look for a rubber one, but no promises.
BRAVO!!! You have one, great looking bird with that tail cam view. That's very cool.
That view will look great in flight.
Testing is testing, I believe all airplanes have a never exceed crosswind component. Seeing how this is considered a Home built, you must have some idea of what that maximum crosswind should be.
In my models, there is a big difference between taking off on grass as opposed to hard pavement.
We try to start our takeoff slowly building airspeed, and as soon as possible, raised a tail to get that rudder into the slipstream to get more control. Anything we can do In the grass it’s much more easier to do.
I can imagine you would want to get that tail up in dead calm conditions.
Another thing I haven’t heard you talk about is what is your anticipated V1 andV2 airspeed.
PS because these are models, between 30 and 45 pounds and of course very expensive anything we can do to make them fly more scale and easier in Crosswinds and takeoffs does and can certainly help like Giro stabilization systems. But Dino, your stabilization system is the seat of your pants. More power to you. NWR😊😊❤
I agree with everything you just said. Thanks No data on the V speeds to go by. I think it will take off between 65-70 mph.
@@Dynodon64 didn’t I hear that there’s another corsair half scale already flying, I think in Tennessee or Louisiana?
@@nealrehm6900 I haven't heard of any other WAR Corsair still being flown today. There may be, but I haven't heard of them. My friend has a P47 he's going over right now and will be flying soon again. Other than his plane, I know of no one else at this time.
This looks amazing
Beautiful plane!
👍👍👍
You go Dyno!
🪶
Amazing Tail View
Glad you liked it. I'll keep mixing it up in future videos.
Ive been watching for a while now and enjoy every minute watching your progress building and taxing I remember my first solo many many years ago
@@wazboagie2338 I soloed in 10 hours myself.
The kindest pricktease ever offered, thank you again Don
You're doing it right. Baby steps. It will not be long before you go for it.
I think we are all getting tired of waiting. I understand testing but this is getting old. I hope the best for you.
he's just doing his best to ensure the first flight isn't also the last
There’s a whole process you have to follow to be legal in the experimental category. Multiple taxi runs at different speeds are part of it. I guess he doesn’t need to post everything, but this is part of this build getting airborne.
In due time.
@@spyder7758 Thanks for the support.
@@matthewf1979 Thanks for the support.
Just fly the thing
I don’t get it. Why is it always about the camera and the mount. Just get the dam tail up and go flying. It’s already July; before you know it summer will be gone. Just my two cents worth.
#1 It's not your airplane.
#2 He will fly when he's ready.
#3 I think he doesn’t have the nerve.
If I fly it without a good camera view, then you will bitch about it, and whine why don't I get someone to record it!
@@brianeisner492 No, I'm not stupid to push it beyond my current limits.
You haven't built a plane before
