Vertical climb with a snappy recovery is always magic, to me. This airplane especially so. Almost seems like you have autosurfaces kicking it over. Just beautiful flying.
Yeah this one has turned out really well. I helped Caleb build one and his flies exactly the same. The foam and the split wintips make these much easier to trim than old school gliders, but you do have to know what to do with them. I've got a couple planes with autosurfaces and I fully understand Dan Berry's mantra that autosurfaces are for driving cars on.
That's the ideal transition with these. This airplane turned out to be exceptionally good at doing it reliably, however most of the top fliers tune their planes for something similar.
That's what I was thinking. I've not flown in a while, but all of mine would do a half roll at the top, rather than just leveling out. Maybe designs have changed to make that regular?
The big change is the foam flaps and spit tip sections which allow a greater degree of control over the rollout. For higher ceilings we still use traditional setups with a standard rollout into the glide.
@@desertblbuesman Materials have that ability…watch an aircraft certification video, the one where they deform the wing to failure. That little glider is quite strong 👍
You easily have a box to put it in. Look at the latch top type Tupperware type boxes behind you, a utility knife, and a hot glue gun, you can make a custom, latch-able box easily from that.
If it’s so cold inside wouldn’t the hot air created by the lights create an updraft? I see some fans up there that are meant to push the hot air to the sides of the building, I believe an updraft would be created by the hot lights with or without the fans on
We flew a lot of different stuff in there and saw no perceptible effects from the lights. And the other planes are super sensitive to even minute air currents.
@@douglassummers9901 it's an optical illusion to the best I can determine. It does loose height much more rapidly below 10 ft altitude because of the rough air at ground level. We never did figure out the cause of that, however it may have been from people walking in and out of the building.
I think you mean "attitude", not altitude, as a glider cannot hold altitude without thermal activity. It will always consistently lose altitude in still air.
@@jimsmalleimb7709 In a sense, yes. What I mean is, it conserves altitude efficiently, but attitude certainly comes into play, as the plane under advisement suffers less than some from the 'droop and swoop' phenomenon..
@@williamrobinson7435 Dude, there's no need to attempt to insult me. Clearly, you are the type of person who must double down on or excuse your error when someone dares to correct you. You can call me pedantic if you like, but self-esteem has never been a problem. Look in the mirror if you want to see someone you're describing.
Got Depron, Balsa and Carbon, never heard of Vector board before. Hmm EPP, sounds perfect for my models that always bumped things. Got some EPP, never thought of slicing it for indoor models, but I have sliced Depron. Need to go down this rabbit hole and learn these new tricks.
@@joshuawfinn I found my old hot wire Depron slicer the other day, just need to clean up enough bench space and try it on EPP. Found out about the oscillating wire CNC cutter, so want to make one of those. Used the 2.5W diode laser on my 3018 for the first time yesterday, it might be enough for balsa, just need to put it on a bigger XY frame, CNC kits, I can make spare models.
First build, I'd go with the One Sheet Glider or Nat Glider, as they can survive the learning process. If you're comfortable planing and sanding an airfoil, try a Carbonette 12, they fly extremely well.
I’m new to this type of things…please forgive my ignorance. How do you prevent these gliders from running into the ceiling and other obstacles, especially with the propeller driven planes? Do you have some sort of calibration/gauge of how much to wind up the rubber and or how far to pull back on the band for the launching gliders?
We do spend a fair amount of time adjusting for climb or launch height. For gliders you have to develop a feel for what power is needed. For rubber powered prop planes, we use a torque meter to monitor the power.
In the case of this plane, the flaps and wingtips are quite flexible so that the plane zeroes out at high speed (hence if it stalls the transition, it comes straight back down like a lawn dart). High ceiling planes actually fly a continuous loop in launch so that they roll and pitch upward from a steeply banked launch opposite the glide circle direction.
@@joshuawfinn ... Thank you for the explanation. I am an aeronautical engineer and I taught Aerodynamics at college, but the principles around free-flight model planes are totally alien to me. It's a nice application of aeroelasticity that in college we only studied associated to phenomena as divergence, flutter and control reversal. I.e. undesired stuff.
I have never lived anywhere that has a facility where indoor flying could take place. so I have never done that. I have been into flying model aircraft a long time, mostly RC glider, designing & building most of my gliders, even flying wing. However, I have never seen any free flight glide launch so vertically, just bunt over into such a stable glide. Obviously you put a lot of work into that but, how in the world do you do that? What are the principles involved in getting that to happen?
The flaps on these gliders (the foam part) deflect upward under high speed flight, and that combined with a little flexibility in the wing makes the model nose over. I use the wingtips as trim tabs to force twist in the inboard section of each wing to induce the desired roll on the way up and some rudder offset to yaw the model the right amount. CG is tweaked to get the glide happy, stab incidence is adjusted to ensure that the model is decently forgiving of less than perfect rollouts.
Sounds like you had a surprising weekend. So flying with a tattered plane and being successful means a ham fisted guy like me can build a relatively good flying plane. I’ll have to go back and watch to build vids.
Very surprising. It was literally a last minute idea, I grabbed it as I was finishing up my packing. When it comes to flapped gliders, the trick is having a good design and adhering to it with the correct materials, and then, much more importantly, knowing how to trim it. The Science Olympiad business forced me to learn how to trim them. My original Super Protégé trimming video is probably still the most comprehensive publication on that topic.
Hey Josh i was wondering how you get access to those huge open rooms. Edit: I need your help josh, I used a heat gun on a wing and tightened the mylar too much and now the wing is a little bit twisted. I put some coins on the corners and left it for about 3 days and it got most of it out but some is still there. Has this ever happened to you, and do you have any advice on what to do?
Bahahaha! Well staying out of jail is preferred. Seriously though, Kent is pretty expensive at $1500/day, same with most of these big sites, so when we get a critical mass of folks and a pricing agreement from a suitable venue, then the agreement gets signed and there we go. For smaller sites to do practice flying and local meets, consider looking for vacant warehouses, barns, and community centers in small towns.
Perhaps if you turned less sharply, the plane would stay aloft longer. Turning a plane tends to make it lose altitude because one wing will have less lift than the other. Very impressive though.
@@markmalasics3413 it's my channel, you decided to troll it. You've demonstrated you haven't a clue what you're here for. So yeah you look pretty dumb from here.
Nursing torn rotator cuffs. ;) Seriously though, we still fly hand launch. The plane in this vid got 3rd in indoor hand launch at the 2021 Nats, and I got 3rd last year with a different plane. My Polly C took 2nd in Outdoor HLG last year, and my Polly B has won 2nd in OT HLG the past two years.

That glide is flatter than fresh roadkill, Josh!!! Congrats

There is something really magical about the way free flying airplanes fly. Just mesmerizing.
Yes sir! That's what keeps me at it. Just can't get over how beautifully they fly.
@@joshuawfinn - it's home is in the air and that's what where it wants to stay 🎉❤
Congratulations. What a wild but consistent transition - looks like a mini bunt straight into it's right turn.
That's the ideal transition with these. This airplane turned out to be exceptionally good at doing it reliably, however most of the top fliers tune their planes for something similar.
Well done Josh. Congratulations.
Yes, that is the best free flight glider model I've ever seen.
Good job on avoiding collision with Kent State's steel roof structure. 🤠
Congratulations, Sir! Thank you for sharing your accomplishments with us!
Congratulations Joshua!
World record attempts are awesome! Congratulations on your accomplishment and good luck on future endeavors.
Awesome performance. Congrats!
Wow, Josh. That's impressive!
The transition at the top of the test flights so smooth and effortless, fantastic flyer you’ve trimmed 😃👍

What amazes me is such a light structure survives the sling shot launch.

I wish. It would take at least 4 of those spliced together to fit this awkward thing, and then have fun lining up the latches.
Really really nice work...congrats... must go back n try building some gliders myself... thanks for inspiration!
Now this is what I like to hear!

I wonder if you can get enough people under it if it will thermal inside?
I made the mistake of standing under its circle a few times and that caused it to dive in. It just can't handle the turbulence.
Love those transitions!
Hard to believe how consistent it is. I only had a few that weren't nearly perfect. Such a fun airplane!
The crowd went nuts! 😀

Randomly tuned into this. You seem easily amused ! Sort of like a cat with a ball of string.
Congrats!
Absolute dream 💭
i wonder how much better it would do in straight line flight, considering turning loses energy
Dunno...my trim inputs were based on flying it in a much smaller site and I was reticent to change things too much with it flying so well.
Wow can that thing fly.
I didn't realize ground effect went up to 40 feet.
Hahaha! Really looks that way doesn't it?
👍way to go 🎉
Why so tight on the circles?
I had it set up for a much smaller flying site and since it was flying so well, I decided not to change it.

We had that discussion. Unfortunately it would have meant completely retrimming the plane which seemed unwise given how well it was flying.
@@joshuawfinn well, maybe you should just take the chance and trim it.
