Saw one of Dennis' motors run last weekend and all I can say is don't miss out on buying this engine. The engine has power throughtout the whole track. The combination of Dennis Richey and his motors are going to send other manufacturers back to the drawing board. The other motors that ran against the RD Motor were a Maxy Modified Salven, JP Modified, a couple of RB's but I don't know if they were modded or not...wasn't really paying attention to them since the RD Motor caught my attention on the track. Can't wait to run one. Great job Dennis and RD Logics.
