I have a H9 Twist 60 with an Evolution 100 NX on the nose. Let me say it is more than enough power....WOW! My problem is..........It's too loud! I have the OEM muffler on it, & anything over half throttle makes a lot of noise. I can't keep flying it this way. The stock muffler does not have a baffle in it. I see on Horizons web site that there are two different mufflers with different prices. Does anybody know if one of them is baffled? Or if anyone else has this problem? Thanks in advance............
