Default Does anyone know about flaperons?

I see ads in the model airplane magazines for JR transmitters and the ads mention flaps coupled with elevators for tight loops. When I read my manual for my JR transmitter, I can't figure out how to do that or how to set up flaperons. Does anyone know how to do this, or know of any articles I could read that explain this in laymen's terms? Bob

Flapperons will allow you to make your ailerons go opposite of elevator inputs while still acting like ailerons.

Example,

Up elevator = down flapperons
Down elevator = up flapperons

Usefull on fun-fly type planes.
Generally, people put them on a switch so they dont have to be on all the time.

Elevons have the mixing I described in the tail surfaces or on a delta wing.

Flapperons as I described relate to normal ailerons working in conjuction with a normal elevator.

I have flapperons and they have nothing to do with the elevator. They just allow you to engage flaps and still have aileron control. At least I thought they were flapperons.

This is what Bob originally asked.

You are right, you do have flapperons. Yours just arent mixed with the elevator.

I explained them in reference to what he originally asked.

Wayne, Thanks for the information. Is there a way to use a switch on a JR783 transmitter to use the flaperons? Bob

I fly an 8103 JR radio so I am not familiar with your radio. I am sure you can though...

Go to the Radio support forum and ask Danny at JR. He is a great guy with tons of knowledge. You'll have an answer by lunch tomorrow.

Please see my post under the "Device to provide elevons?" in this same forum. There is a description regarding mixing the different control functions and what they are generally referred to.

With elevons, you mix the functions for elevator and ailerons together. This would be used on a flying wing type model where the only control surfaces would be the controls at the trailing edge of the wing. You could split them - making the outer part an aileron and the inner part an elevator. But mixing a single control surface to do both jobs is more effecient.

When they are mixed, the control surfaces on both wings work either as ailerons (working in opposite directions) when you move the stick right or left, or as an elevator - moving the same control surfaces up or down in relation to the elevator stick movement. You can see that by holding some "up elevator" the controls would be in that (up) position, but you can still give right aileron control for instance while holding the "up elevator".

Flapperons involve mixing the flap channel with the aileron channel. They are similiar to elevons but when using the "flap function" the "flaps" stay at the position on the non-self-centering flap control on the transmitter. So you can have say, constant "flaps down" while still being able to have aileron function with the same control surfaces.

Another system the control-line folks have used for years is coupling the flaps with the elevator. Flaps move opposite the elevator. This can give some extremely tight loops - both inside and outside. I've also heard of some R/C'ers using this system years ago.

Its being done all the time now.

Fun-fly type planes benefit from this mixing for wild maneuvers.

Just to confuse this topic a little more.........
On my 33% cap 232 I use Spoilerons. This makes the ailerons go up with up elevator. It helps on some 3D maneuvers such as harriers, walls, terminators, etc, etc,
Anything where you need to stall the wing out quickly to get it into high Alpha (3D)

Bob,

I'm not sure how to do this with the JR783, but on my web page http://home1.gte.net/drandles/radioc...switching.html

I describe how I did it on my JR 8103. It should be similar.

Default Flaperons

Bob,

I used to have a JR 388 which is practically the same as the 783. I'll try to remember how I did it and, as has been said, it is about the same as the 8103.

First, you need to go to the Model Set-Up Menu where you select the model. Choose a Wing Type of Flaperon.

Next you must have 2 aileron servos. The right one is plugged into the aileron channel (ch 2) and the left one is plugged into the flap channel (ch 6).

Third, go to the Functions Menu and Set your servo reversing.

Scroll up to, I think, mix E-F.

Hold full up elevator and press either + or - go set the flaps (both ailerons) to a down position. I usually use 100%, but you can use less.

Hold full down elevator and press either + or - to set the flaps to a up position.

The switch that controls flaperons is the Elev-Flap Mix switch. This is the 3-position switch on the left front of the transmitter. The center position is off. The up, Elev, position is on for flaperons. Down is the Land position if you set flaps, etc. for landing.

If you need more into, e-mail me.
