RE: OS AX-GMS-Magnum-Tower - muffler differences
Thanks for the feedback Ed. I really should subscribe to RC Report. Too bad they haven't gone web page yet. I think I'd be willing to pay for that. Re engine testing at RC Report, I had the impression in the thread you were involved, not just doing it for personal interest. Re the Macs muffler, I like them because they're light, clean looking and more aerodynamic. Actually lost RPM you say! Might have to play with opening the exhaust opening and compare... in the summer when it's nice outside again. Too cold to play outside now! Cheers
