Whew!! I just finished reading this humongus thread and I took the plunge... I have a Patty and a DA 50 coming from RC Superstore.com - they gave me a great price and are shipping both for free!! The only thing I did'nt get was a muffler, I called DA to see if anyone was working on a Pitts style that would'nt rob any power from the motor and they are'nt aware of anyone working on anything... they also said that the Slimline or the Bisson (with the ends cut) are quieter than their straight can and that I probably would never notice or need that extra 300 rpm on the Patty...I Cant wait to get this baby - Guess I'll help keep this thread goin for a while longer....
