I am on a revision that seems to be holding together nicely. But its only been raced for 2 rounds, so I really don't have a lot of input for a term that I consider appropriate. The R3 seems to be faster in a straight line due to the nature of the twin engine, but the RC has it beat in the handling and brakes by a mile.wow, this thread petered out quickly, at my local track, people seem to be running from their fully-built RC's to R3s. Makes me wonder if its an opportunity or a warning. . .
