Freek,

I think I have a ligher setup than some. I'm using the Saito 100, which is a very light engine. A YS 91/110/120 is in the neighborhood or 9-11oz more. Servos are HS-625MG, 1.9oz each. The battery pack is an 1100 5-cell. Only additional weight is a SIG tailwheel which probably weighs an ounce or two more than the stock one. I've got 3oz of lead on the front of the engine mount for balance. Currently the CG is about 7-7/8", possibly a tad more or less.

I can tell you for a fact that the wingloading is not way above what it should be. This thing floats forever!
