It's all relative to the size of the plane and the size of the control surface.

On a plane with a short control surface, 1" can represent extreme movement of the surfaces....

E.G. on an Alpha 40, this is a tremendous amount.

On a plane like the Laser, 1" might be small enough for a "lazy" or loose loop.

It depends upon the plane.


The Yak is built for 3D manouvers with high rates....

Being able to snap it hard, is part and parcel to how it is supposed to fly... but this can cause problems for the pilot if they forget about it, or try to fly it like a trainer...

On a Yak, letting the plane "settle in" to a landing is a good way to assure that it will snap.

Coming in under power will prevent this.
