ST, got ya on the servos. What motor are you running in yours again? I will let you know where my batteries end up, my hope is the ignition bat goes up forward of the tank and the RX bats end up aft the tank where the ignition bat is now.. It's a nice spot to make a battery tray, but we know that never works out like we want.. I do plan on putting smoke on it this winter, long as i feel the extra weight won't hurt how shy flies...
