I like the mufflers on the Fox 15, as it gives your hand a firm gripping area for a better hurl!
Actually a much more user friendly engine for the Akromaster is an OS, Magnum, or Thunder Tiger .10 , as these have plenty of power, light weight, use common fuels(and not much of it!), and fly a light Akromaster just fine. I actually have a Supertiger X-11 on mine right now and it has PLENTY of power, but they are somewhat hard to come by.
Scott,
I have the OS and TT in .10, .15, and .25 and they all work fine. In fact one of my TT .10's is in the other Akromaster shown previously. I have a Magnum .15 but it has not yet been in a plane.
I also have Fox .15's including original (bought new when they came out) "steelfin" Rockets, the .15X's shown plus a couple more of the middle ones, the schnuerle in both plain and BB in both RC and CL and fortunately not a bad runner in the bunch. I DO take the time to run engines on the bench, break them in, and get used to their particular characteristics...they don't all run the same.
BTW, I use the same fuel in them all. The only Fox that needs excessive oil is the .35 stunt
AFAIK.

PS> I would never hurl an engine.
