Venus II spec is for the balance to be at 6.5" and says it could be varied 1/2" either way if desired for a permissible range of 6.0" to 7". My balance point (empty) was at 6.45". With a full tank, the plane balances at 5.6" and, after a typical 8 minute flight, it balances at 6.0. So, the question is, should I do the empty balance at 7.0" which would shift the full to 6.1" and the landing to 6.5"? I do notice that I need to re-trim at the end of the flight.

I know, move the tank to the CG!!!!! Before that, though, I'd like to see how the plane handles at the 6.5" CG.
