starcop - no CG issues with mine (didn't add any weight), but I have a YS 120 up front, a large 6V RX battery up against the firewall above the fuel tank, and an onboard glow driver (which sits ahead of the CG). Came in at 11.2 lbs.

Other than a tendancy to climb on throttle, no real bad habits (other than that pesky landing gear!). I'll mix some elevator to throttle, program aileron differential, be good to go.

Steve - watched on NEXRAD when the weather was headed your way (and towards Jordan) - I'll stick to my earthquakes
