Snap Rolls... I've been wrong all this time..

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....

The way I do it is to have a ton of aileron in your snaps to make it fast. My 3D rate and my imac rate on ailerons is the same. I have very little elevator, and I "pop it" or jam full elevator then put the sticks in the corners. If you do that, it will make you consistent with your snaps.

Well.. it simply boils down to using whatever controls makes the plane do what you want it to do!!

Start a positive snap and go to DOWN elevator.. unless you are in 3D rates... likely the spin rate will stay positive and increase!!!

I have note read the thread through but my 30% yak will NOT snap 360 degrees if I dont use the ailerons no matter what I do, they are the most important part of the snap.

Dude I do not know who this guy is that you have respect for....I understand. But I have always used ailerons to snap. I mean think about it dude. You use the elevator, rudder and ailerons. I mean that is what I use...I watch Snap-o-saurus and he is in European mode and he uses ailerons. So I respect what your man says but I do believe you have been right all these years. He may just do it differently. Seems like it would be harder to do it that way.

Gremlin, is this just a ploy to take away Snap-A-Saurus's ailerons?

In all seriousness, the rudder/elevator snap is a "true" snap roll, however, it only works on aircraft with higher wing loadings.(I'm talking more than a 50 .lb 35%) some model warbirds will do it well, the early cap 21, and cap 231 .40-.60 size models did it well too, but with today's technology and rediculously light wing loadings, a rudder/elevator snap is virtually nonexistant in modeling circles.

I was waiting for this. Any scale flying aerobatic plane that was desighned in the 1970's and 80's such as the Cap21, Pitts, Chipmonk, Laser 200, Zlin and so on would snap like the real thing and in some cases elevator only, and look out for the secondary stall. Remember that a snap roll is a stall manuever. But with todays Wing designs and loading its impossible to do it. I would love to see someone even attempt to slow down a Cap 21 to do a harrier. It would snap and spin into the ground in a heart beat. AKA the snap 21. Great point to make that a real snap is elevator and rudder only but that only applys to aircraft you have to fly to the ground and not the over powered kites that we fly now. The tip stall snap has been built out of our planes of today.

When I was learning on a 150 aerobat, a snap was explained as a horizontal spin...elevator and rudder only. Use Aileron and its a flick roll. Models work very differently and almost always need aileron.
