Modellbau U.S.A. MB-339 CG
Whats the correct way to measure the C.G. on this bird. The manual states 195 mm from the leading edge. Is that from the front of the intakes, or what would make the leading edge if the leading was extend across the engine intakes. Also, saw somewhere that is was 220mm. So I am confused. Any help would greatly be appreciated.

If you have access to a small scale, you can set it very easily. Put the scale under the nose wheel and block up the mains so all is level. The scale should read approx 2 lbs or a bit more. Mine flys just great and shows 2lb 4 oz. at that setting, Any questions pm me.

Hal,
When you do it that way, how much fuel is in your UAT if using and main fuel tanks?
How does the plane fly, anything I should look out for?
What is your powered with? Mine has a Ram 500.
Thanks for your help.
Sincerely,
Jason
