Hello, my name is Ed. I live in Afton,Wyoming. I started flying helicopters about a year ago. Just planes before that. Learned on a blade 230, actually started with the mini s3 helicopter. I have a blade 230. And Oxy 2, OXY 4 And OMP evo 2. What brought me to the site is I have a question: on my oxy 2 it has the one way bearing installed. The other day after a flight my friend who is help me a lot with the helicopters asked me why, the tail rotor blade stopped turning while the main rotor was still turning. I told him I thought it was because of the one-way bearing, but he thought even with the one-way bearing it should still rotate the rear rotor. So here is what I have, if you turn the rotor clockwise it spins but gear and tail rotor don’t spin. Note the main gear and belt gear are not independent. if I turn the main gear, clockwise the main rotor and the tail rotor engage. Turning gear counterclockwise tail rotor turns but not main rotor. With the main gear and tail rotor pulley one unit I don’t see how you could have any other outcome. Please correct me if I’m wrong. I’m hoping I can learn a few things from you guys That have been doing this a lot longer than I have. any help on this subject is Greatly appreciated. BYW. Be kind, I’m older. (lived through the 60’s twice.)
