OS 120 AX muffler?
I'm ordering a 67in OMP fusion and going to put a OS 1.20 ax on it. What muffler do you recommend?

Re: OS 120 AX muffler?
I built two of them for Randy's Hobbies in Houston (shameless plug!) and they had the 120 AX on them. I used the standard muff and took out the baffles on both. Talk about a real ripper........

Re: OS 120 AX muffler?
Another vote for stock... ran one for several years this way. Made more than enough power for my application, but I would take out the baffle.

Re: OS 120 AX muffler?
I had a Fusion with OS1.20. Used the standard muffler. You will have to file the engine mount just a bit to get the engine in. Great plane and great engine, unlimited vertical. Also the engine servo space could take only a micro servo, so I used one which failed in a few flights probably due to the vibration. Cut the hole bigger and use a std servo if you have the same size on your plane.
