RE: Tail-heavy Top-Flite Spitfire
Need to be careful going too far forward with the CG.
l have test flown planes balanced in this manner that were ill handling excessively fast landing lead sleds.
With the CG set beyond the forward limit, power reduction and the drop in airspeed that comes with it will require a larger up elevator deflection to control the rate ol descent.
This will lead to higher approach speeds on final and the possibility of forcing a stall or running out of adequate up elevator to arrest the sink rate before touch down.
