How do I do a snap roll?

Guys can I just confirm how to do this. A snap roll is full up elevator, full left aileron and full right rudder correct?

It all depends on the airframe. For 3d planes, it's mainly punching WOT quickly going into it, then giving full up elevator, and full right aileron/rudder (or left). For inverted, you give it opposite aileron as rudder.

Then for sport planes, some will like to do it better inverted than upright, and others will like to do them upright. Then SOME will do it the same either way

How about that, thats what I thought it was. But for some reason I cant seem to do blenders on the sim using 3D planes. I climb high, put it into a dive with little throttle, left aileron for a few revolutions, then full down elevator and right rudder and medium power. Plane sort of goes into a spin, but its certainly not flat and it keeps falling. Stupid hobby, why is it so hard

I thought if you were rolling left, you would give left rudder to make the left wing drop faster. Isn't that what makes it snap over?

That's what I thought too. At least that's how I've been doing them. Bang both sticks left or right = snap roll.

Both sticks in the same direction for a snap. slightly off topic I know, but I've been doing what I was told was a "sullivan" roll. A really cool maneuver, basically a snap but with opposite rudder. You lead slightly with the elevator and it's always a climbing maneuver. Come down the runway, full throttle, lead with up elevator, hard aileron and hard opposite rudder. If you're disciplined enough to always lead with the elevator, you can do it on takeoff, if not, well ......

The June 2010 issue of MODEL AIRPLANE NEWS has a whole story on how to do snap rolls with all of the positions of the transmitter controls.

No, you'll need left rudder if you're rolling left. Right rudder is going to push it out of the blender

Sullivan Roll!
Guess that's what I do .. It just looks so pretty and flies right out of it when released.
Though I think I am leading with the rudder. Now I will make a conscious effort to lead with the elevator.
Thanks

I don't think that's right. If you're inverted, you want right rudder. (this is for a blender, which Mike says ends in an inverted snap roll)

Thats what I read, but I just cant seem to do it. It doesnt sound very hard to do, but my plane just slowly spirals down to the dirt. Maybe Im letting it dive too long and build up too much speed, I dont know

"slowly spirals to the ground" sounds just like an inverted flat spin, which is essentially what you want. If it is flat, the addition of a little throttle will keep it from descending quickly. If it isn't flat, it will race to the ground faster.

He said "snap roll", not blender.
