Bob,

I ordered my Excelleron, expected delivery is next week. Like you, it is hard to argue the cheap power cost of a ST2300. The extra wing loading seems minimial. Looking at this option, I see the extra weight forward (i.e. ST2300) and extra weight (as you said move the battery to the tail) would increase the yaw moment (mass)? My question to you, as I'm not more than a Tiger II pattern want-a-be, would this be a problem for spins (i.e. extra mass means harder to start spin and harder to stop spin)?

Greg.
