Super loop
 

I was wondering if anyone has tried this, or even if its possible. First, I need to make sure what i know is right. Flaperons are when ailerons drop down, and elevator is mixed it to go down, so the added lift from the ailerons is balanced in the back. First, is this right?

If this is correct, what would happen if you used up elevator. So the ailerons raise from the added lift and the elevator drops. Would this cause a really tight loop? I would expect if you programed the flaperons to drop to almost full throw and same with the elevator, it would cause a really tight loop. Has anyone tried? Im getting a foamie, and im deciding on one or two aileron servos. If this is possible, I might just get two servos for this super loop.

So, has anyone done it, and is it possible? THanks

No. Flaperons, specifically, are simply drooping the ailerons to act as flaps. While one certainly CAN mix in some elevator to achieve/offset various tendencies, flaperons themselves refer only to the ailerons.

My own guess would be that you'd stall the airplane in a pretty big hurry. Of course, since we're talking about a foamy, that's really not an issue (unless it snaps out from under itself)....the thing's not using its wings half the time anyway.

Of course, given the size of control surfaces on most foamies, and their P:W, a fair number of them can do the "super loop" you're talking about ANYway.

But hey..why not try it? that's the beauty of a foamy...take it up a few mitakes high, and give it a shot...worst thing that'll happen is the thing tumbles around out of control...flip the switch back to normal elev/flaps/ailerons, and fly away. *heh*

I do that with my Goldberg Wildstick 40. I put in flaps (real flaps not flaperons) and pull the elevator. The thing does a loop that is a little over the length of the airplane. It's neat as hell.. almost looks like the tail caught up with the nose.. :D but I don't do it unless I',m 'a couple mistakes high' as gb pointed out.

awesome. I cant wait to try this out. Now, I just need to get some money to buy the foamie. The price came out to be about $200 more than I hoped [&o] .

It may be a good idea to take into account that this is most often used in fun-fly planes, or models specifically designed to withstand high stress loads. A foamy may not take to the stress so well and fail structurally.

RE: Super loop
 

Yeah.. you may find that some electrics are much (maybe a little more.. ;) ) more expensive than glow. LiPo's, ESC, motors, receivers, servo's, and the plane itself. At least with a glow you can get an engine fairly cheap. A decent one a bit more expensive. But often, the cost difference can be a bit of a shock.

RE: Super loop
 

You are so right. The Goldberg Wildstick is pretty sturdy and seems to be able to handle even my sloppy flying.. :D but it will do some crazy things, that's for sure.. even land!! ;)

RE: Super loop
 

What you are discribing here is elevons, which is when the ailerons drop and the elevator goes up, which does make for a really tigh loop, but as stated above, some planes will not handle this kind of stress.

Good luck!:D

The plane im looking at is called the "Nasty". It has a 38" wingspan, which has a carbon fiber rod going down the wing. Heres a link http://www.rcgroups.com/forums/showthread.php?t=390003

Its scratchbuilt, so if you all think it wont handle it, I might go up a size for the carbon fiber rod, for extra strength.

controline stunt ships have been doing this for yesrs in order to get 90 degree corners to do square loops.

Elevons are a dual function of elevator and ailerons, as often found on delta wing aircraft that do not have separate elevators apart from the wing.

RE: Super loop
 

Jim Dines is correct when he describes elevons...

There are instructions for setting this up on JR radios in the Uahgar 9 Ultra Stick 40 manual and programming guide.

RE: Super loop
 

seems to me the challenge isn't in doing itty bitty loops...but the great big loops

RE: Super loop
 

Yeah.. those big loops can be a challenge. Just quickly pulling on the elevator all the way gives a quick short loop. Good for Fun Fly events (most loops). But the real loops, the large ones, require some coordination, with the main part of the loop is the starting point. It must be straight and level. So, it requires some good trim adjustments to get real straight lines with "hands-off" and at one speed. Then once entering the loop, it requires a close monitoring of the position of the plane to keep the wings level all the way around. Then, coordinated throttle cut at the top of the loop. When done right, it is a pretty maneuver.

But my favorite maneuver has to be the long-slow aileron roll. Now that's a pretty move. Difficult to do because it also requires some coordination of movement also beginning with a straight line. Then the aileron roll has to coordinate the nose position using the elevator to keep the nose straight and level. Definitely requires some hand-eye coordination.
