I figure that would ne nessacery, since the head is "up"on the stand and the fuel tank is low and it will be opposite in the plane. I just hope it is not too far off and I can get it as close as it was prior to installing.
I plan to "ground test" the model on a long paved open lot near me without the wings for assurance it does'nt get airborne. Ill try the mixture control and get a feel for its ground acceleration to gauge how much real estate I'll need for T/O and taxi it around for a feel of the steering and see if I get the "Byron Boogie" and cure that as well.
