Hobbsy,
I have two of these older Webra .91 Speed engines. I have yet to use either. I need a muffler solution and I see the ST on yours. How well does this setup work? RPM on the ground/prop? I have the Dynamix on both. After reading all the stuff on the Dynamix, maybe just leave the OS 7D carb off and go with it. I may use one in a AKM Models Su-27 if it will perform as needed. Let me know what you think. Tuned pipe recommendations will also be helpful. Glad to read less nitro is good too.


Thanks, steelie211 Dan
