I have a older model Skymaster T-45 , The Instruction page calls for the CG to be set at 180 MM from the leading edge of the wing. A friend of mind who is a engineer was looking at it & did some calculating has mentioned that the CG should be closer to 10 " or about 250 MM. Flying the plane for the 1st time this past weekend, I had no problem with no flaps , but with flaps it seemed to have a Elevator stall.
I would like to know what other's are doing ( CG Wise ). Also with the Flaps upthe plane tracked very well.Thanks for any help on this
