I have an OS FS-70 powered Revolver and did a kit review for R/C Report magazine. Balanced correctly at 110mm. it is an excellent flying plane.

You did notice the control movements, I hope. Low rate on elevator is only 5/16" each way and high rate is 1/2" each way. This is not very much.

If you use excessive movement, you can easily snap the plane. Bear in mind it is not a 3D plane for doing hard up walls, but more of a sport pattern type plane. If you are used to a very light 3D plane with a thick airfoil, you'll have to learn how to fly this plane, which is heavier and has a thinner airfoil. It does snap fairly fast, but it is controllable. An avalanche is one maneuver where you use a snap and it's easy to do.

The low speed handling is also good, but bear in mind it isn't going to slow to a crawl like a light 3D plane.

You might also want to put in some exponential on the elevator for smoother control input.
