Snap Roll

[ToddO]

I know this must be very basic to most, but I can't seem to find detailed information on how to do a snap roll. I have seen breif decriptions, but they really don't tell me how to do it or what it looks like in action.

Any help would be appreciated. Best Regards, ToddO

What i tened to do is bring the airplane going straight up, then pull both sticks to the LOWER left bottom of the radio and holding there for about 5 to 15 seconds. depending on how the airplane handles in the air. you can also try this in level flight but make sure you have ALOT of room to play with between you and the ground!:D ;)

The basic snap commands are full up elevator and full aileron and rudder in the same direction. The plane should do a sort of somersault in the air. You need to have plenty of airspeed for this to work. If you have a plane with significant vertical performance, you can do a snap while going straight up as Strega suggests. Strega is also right about not experimenting with this maneuver unless you have plenty of altitude since it's hard to know exactly where your plane is going to end up after a snap.

If thats a snap roll then what it is when you give full up elevator and full right aileron and full throttle and left rudder? Whattever it is it's violent!

The definition of a snap roll is a roll caused by one wing stalling. It's like a spin, but faster and horizontal.

It's possible to do it with no aileron at all on many models. Pull in full back elevator and full rudder, together and suddenly. Release the elevator after 180 degrees to reduce drag. The plane should still rotate (quickly!) until you release the rudder.

Yup, many r/e models snap roll very nicely. I have a small 3 ch bipe that rolls quite axially on rudder only, however the slightest touch of down elevator when inverted (to keep the nose up) gives an instant and extremely violent negative flick (snap) roll! This is extremely spectacular, and quite fun ... so long as you're expecting it ;)

Wow, I've always wanted to know how to do one. I've seen them on video.. very cool maneuver.

Thanks guys!

Although it is very violent!. Could an airplane break apart by doing so?

What can go wrong in a snap roll if not done
properly and how to recover from it?

Is it possible to get into a stall induced
spin if a snap roll is not done properly?

Thanks.

Since a snap roll is basically a horizontal stall-induced spin, you may want to be comfortable with spin recovery before doing one. Not that it's a big deal; just release the sticks and the plane will recover.

Not a whole lot can go wrong if you botch a snap entry as long as you have enough altitude to recover from an unusual attitude. Each plane snaps differently; get comfortable at altitude before trying them ten feet off the deck.
