Fokker ~ Thanks for the tech info's by answering BikerBob's post.... Interesting!!!!

I'm much more simplier - such as swaping motor sizes, batteries, prop sizes until I achieve what I was looking for. Learning by trails and errors is FUN!!! (Looking at other person build and their selections gives me a general idea on where to start)

In obtaining longer run time without spending truck load of money on high performance batteries/chargers such as lipo's, would suggest looking into gearing the drive train to keep the motor running cooler and extend the running time. Gearing would draw less amp and give more torque, probably would be the best answer beside having to get couple battery packs and swapping them out every 10 minutes. (Just my opinion)
