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.
@joshuawfinn
@joshuawfinn Год назад
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.

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.

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

@@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.

@joshuawfinn
@joshuawfinn Год назад
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.

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?
@joshuawfinn
@joshuawfinn 11 месяцев назад
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.

@adb012
@adb012 Год назад
Josh, how do you manage to shot it straight up high speed and prevent that it starts looping, given that it is trimmed for a slow speed?
@joshuawfinn
@joshuawfinn Год назад
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.
@adb012
@adb012 Год назад
@@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.
@kenwebster5053
@kenwebster5053 Год назад
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?
@joshuawfinn
@joshuawfinn Год назад
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.

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.

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.
