Anyone run a lipo pack with in a stock mini wildcat? I bought a Turnigy 1600mah 2-cell lipo for the wildcat and gained a ton of speed. No gps but its almost as fast as my rio ep. I bet I gained about 3-4mph over the 1600mah duratrax 7.2v nimh pack I was using. Just gotta be careful not to run it too long without a cutoff.
