I have a OS HYPER 50. what is the best muffler combo for 3D high RMP flying? MP2 or Hatori. thanks

The ones I have seen that performed the best in my opinion. They had the Hatori JK special muffler on them.

Thanks david. I thought so too, but I hate the clamp that holds the muffler to the frame.

Terry Moore that is here on Helifreak. He has machined some nice clamps for the Hatori JK muffler. Might check with him about one.

I've found that for peak power, the MP2 puts out a little more than the Hatori Jk does, but that being said, the MP2 is harder to tune, and not as smooth through the throttle curve. At 2100 head speed the hyper/MP2 combo, really produces some awsome power.
