I flew mine for the second time this past weekend, it feels much better now. I moved my two flight batteries from over the tank to over the nose gear, I left the 2100 LiFe turbine battery over the tank. I'm also using a Mercury SRS so my setup is very similar to Joe1199 above. It requires just a hare of down elevator when inverted early in the flight, pretty much neutral towards the end of the flight. I flew my big T-1 right before I flew my T-1 mini and they both feel the same except the mini is much more sensitive in the roll axis. Speedwise, my mini with a K85 feels faster than my T-1 with a KT 140, but I have not substantiated that with GPS/Radar numbers yet. Smaller aircraft usually feel faster to me so it could just be my perception of the speeds.
