I've done all three methods, hard mount, Lee's mount and Hyde mount. And now that I think about it, All three have been successfull from a noise standpoint. My Jupiter with an OS1.40 on a bolly muffler, with a 4 blade and Lee's mount was almost inaudible in the air and I've been asked more than once if it was an electric. My $140 Hyde mount was ruined in a crash last summer (wind shear, and I'm sticking to that story). So this year, all my stuff has Lee's mount to keep the price under control. I get in three-four flights on a single charge (1100 ma battery pack) and I'm lucky to get 100 flights a year. What I'm trying to say is Troy is right in the respect that if you need a plane to last 3,000 flights, better spend the money to do it right. But it would take me ten years to get that number of flights so I am perfectly happy with Lee's mounts, Hayes clevises and rustoleum paint.
