LiPo LiPo LiPo!

Sorry, re-read the thread... 5s on each motor will be enough power. If you truly go 5s2p, you'll be capable of 70 mph if you gear properly. :) good luck!

At those kinds of speeds and weight, you can do some serious damage so be careful!!!

But you know... a single big motor and controller will be lighter and more efficient than dual motors, dual controllers, etc... Why not 10s Lipo and a bigger Lehner motor? 22 series? Wait a minute... starting to sound like Promod's setup now. Heck, go 12S lipo - 6 on each side and get a 40.160 controller. Nobody can touch you then. You'll go 60 w/o even getting warm. You can probably even do 80 with 12S lipo.
