I would really appreciate your help. I have recently crashed very badly and had to replace the frame and main shaft of my heli. When I wanted to put back the collar on the main shaft I realised I do not know which way it should be positioned as it is not symmetrical. Does any one know if it should be positioned as on this picture:
or this one:
Additionally after putting the heli together, replacing the main shaft, feathering shaft and the balancing pole mounting (EK1 0401) I noticed there is a resistance when I turn the main rotor. It's not much of it but it's definitely more than before the crash. Any idea what could be causing it? I attach some pictures below. I would appreciate any ideas.
Thanks for your help
