Hi John: wow..Thanks for the information. You should try to call him...He has always returned my calls..I talked to him a couple of days ago for a half hour..I had all but made my mind up to get one until your post..What other problems has he had. He claims he has had only one problem...also have you talked with Guy Marcotte or have you tried to call his old sales rep. Ray I think WAS his name. he passed away awhile back. I was trying to contact him with obviously no reply.

The pilot bearing was a bushing which didn't work out. It was replaced with a needle bearing that couldn't stand torisional movement of the crankshaft and the PSRU input shaft, this design has now been replaced by a double bearing arrangement on the input shaft to eliminate the pilot bearing. Twice I have lost the oil, 80W, first time due to a vent tank for expansion, the second time the output shaft seal fell out due to the aluminum case expanding faster that the seal, resulting in a fire at 4000 AGL at 190 MPH resulting in a bad landing in a wheat field. I have had no luck contacting Marcotte about getting any information on the redrive and all I know about all the problems I have read in the Contact Magazine, so in my opinion it is a true field test operation and buyer beware.
