I think he got 400 hours out of his before the bearings went. Had to send his prop back to Germany, too. On a related topic: He and I have discovered that the MT prop controller box sends lots of noise back down the 14V buss when the prop pitch is changing causing false "hits" on his Stormscope. An inline filter on the power lead to to the controller has solved the problem. --John
