Please don't flame me... but I have always used ailerons with the rudder when I snap roll. I always pitched first, then snapped. I never realized that it is only elevator first, then rudder. I just read an article by Scott Stoops (I like and respect his articles a lot) and learned this. Who else has been using ailerons? Thanks.

you mean to tell me that all this time I have been doing it wrong?
I too use all three elevator ailerons and rudder to do my snaps, i always thought that you used the ailerons to help the plane roll better, well I'll be jiggered. learn something new every day around here, I will try this the next time I fly

Hey gremlin where did you read this article? I guess I need to refresh on the basics because I have been using all 3 for 20 years. oops

So it is just elevator then rudder?

Ok I could be totally wrong here, but I have NEVER seen anyone flying precision snap an airplane with no aileron. True, many airplanes will snap this way, but it's typical in RC flying to use aileron in the snap. Using little to no aileron sounds more like a full-scale snap...

Yeah guys, If you watch any pro do a snap roll they use ailerons. The snaps would be slopy and slow without them. You were right before hand.

Agreed. Good luck flying a snap like that in IMAC and not getting a 2 heh. It works good for full scale sport aerobatics, not so well in competition aerobatics. There is no rule that you can't use ailerons, just that you have to have a noticeable break to signify an accelerated stall into the snap (a true snap, not just an aileron roll).

I tried this method a few times on models and it typically ends up being a barrel-ish roll and losing lots of energy. So I cheat and use ailerons heh.

You are right. A full scale snap uses rudder and elevator (yes I've flown full scale). Models just don't wrap up good without the ailerons.

Read further in the article and he does mention that some planes will snap better with aileron input and of course planes will differ.

When you use ailerons its called a barrel roll.

For the most part I will agree that for RC scale aerobatic, planes ailerons help the snap. However, some high wing RC planes actually snap better without ailerons. This is just personal experience, and might not apply to others. LOL

iv always had to use ailiron to make it snap fast enough,, tho iv only had smaller planes and they would do it with jsut rudder.. it just doesnt lok the same... my .02 cents

Huge difference between a barrel roll and a snap.

One is a heck of alot more violent

a snap roll on a full scale uses no ailerons and using the rudder will snap the plane around when stalled, but I'm not sure how well you'd go around with rudder and elevator on a model plane

I first tried snaps as a teenager and my father was telling me how to do them. He flew full sclae not models and had snap rolled a Decathlon. He said elevator and rudder only. Some RC planes will snap good without ailerons but mostly if they have a high wing loading or snap tendencies built it. To do snaps with most RC planes you need ailerons to make them look like we want.

So I think rudder and elevator only is a full scale thing like others have said....
