Tom,

I'm not very familiar with the Smart Fly super switch, does it have multiple connects inside it? If it doesn't, than you have the same situation as using a standard MPI switch.

BTW, I balanced my Sukhoi tonight and had to move the receiver battery in front of the landing gear to get it to balance at the center of the wing tube. The plane has a DL50 with the battery and ignition mounted to the sides of the engine box. I'm using the pull-pull for the rudder. I would have never thought it would be tail heavy with the big fiberglas engine cowl. I was planning to go to one A123 battery after I have the bugs out of the plane, but it looks like it might take some dead weight up front to balance it with just one battery. Kind of defeats the purpose on this plane. Is this plane typically tail heavy? Going to the field in the morning to tune the engine and shake down the plane, then fly it Tuesday if nothing big comes out of tomorrow.
