soo...guys! what actually is an IMAC snap? as much as i understand:

*come at medium speed
*pitch the nose up
*give full rudder and aeleron (same direction)
wingtip should be stalled...

but the stupid question is,
*how do i know that the wing IS stalled and im actually snapping instead of doing tumble-roll-whatever?
*the plane should roll on aeleron axis or aeleron-elevator axis? (sorry, allways mixing pitch and jaw)

I'm just a 3D guy who dabble into a little bit of precision . But what it must have is a pitch departure at the start of the autorotation.

Yuuup!

RE: IMAC snaps.
There is a load, snap, set-unload. For positive snaps, there's a positive "pitch departure" load, full aileron, rudder, and generally full elevator at the start/load to kick in the stall, relaxing the elevator through the snap after loading.
Negative snaps have a negative "down pushed" load.

An IMAC snap roll is a stall maneuver regardless. The judges look for the stall, or at least a distinct indication that the nose has gone up a little.
Elevator helps stall during the initial snap, rudder helps kick it around, aileron to add the roll into snap roll.

"The judges look for the stall, or at least a distinct indication that the nose has gone up a little"... yup. to add, they want to see the pitch break and a yaw distinctly before the wing comes around in auto-rotation. If the plane starts rolling more or less on axis before the pitch/yaw, then you get a zero...

Exactly.

I know this is a 3D thread, but for those of you who want the real scoop on understanding all things IMAC, here ya go.
http://training.mini-iac.com/Default.html

Look at the criteria, head down to the snap family videos, and have a real gleg at the differences between good snaps and bad snaps and other IMAC things. Everything you need to know about flying IMAC is riiiight there.
