Nice and cheap how that CG machine is, eh? Easily adjustable also.

Boatman, if you tend to groundloop with that gear, try using up elevator until you get to about 1/2 takeoff speed, when you let go of the elevator for just a moment, the tail will pop up, and you will have rudder authority that you didn't have until you got some speed. Try not to give much up elevator until you get some speed up, mine at least has a tendency to tip stall fairly easily, and seems to be sensitive to crosswinds. Just a heads up. This plane really likes the axles to be more at the leading edge than out front. Good luck on your maiden.
