Question
Spoilerons and Pylon Racing

I notice that some racers set their planes up so that on the straights the trailing edge is lifted a few mm to improve speed and then on the turns the trailing edge is dropped to normal position to improve lift and thereby tighten the radius of the turn.

My question is: How is this done? By a TX mix where the spoileron setting is mixed with the elevator I presume? Or is there some other way?

Thanks in advance!

I mix elevators to the spoilers, so when you pull they come down.

Peter,

This only works on some airfoils, usually not enough gain to make it worth the effort. But those who do it use a separate servo for each wing panel (naturally) and an electronic mix function in the transmitter. On the JR transmitter, it's called the "flaperon" function.

One place where flaperons are helpful is on landing. I prefer to have the ailerons kick up slightly (actually a spoiler effect) as Red suggests. This dirties up the airplane and raises the nose for a slower glide.

Hope this info is helpful.

Cheers,

Duane

Never actually raced with it man, but snap flap is good fun. You do definetly get a boost in turn speed. A few models Ive set up a mix where 100% throttle reflexes the TE of the wing, and up elevator drops the TE (snap flap). As DHG says, it depends on the model as to how well it works.

Set up a few mixes and give it ago

Thanks guys, I might just have to give it a go!




(I use spoilerons on a switch for my gliders and hotliners but never mixed with elevator and/or throttle before and just needed a push....)
