thanks for the info, but one thing, you say its almost impossible to balance a ag plane. with the loads and all, but as a moddle, it dosnt dunp a load , only the fuel from the tank I use, so wouldnt this make it a differ matter, of would the fuel tank kinda be lick the hopper in a ag plane, only not dumped as fast. ive seen the agplanes fly around my school, it seems they only are in the air at least 15 mins max, so that seems that my R/C agwagon would also kinda be scale in that matter.
