BCP major Vibration before takeoff

[New-heli-pilot]

Ok, so my BCP has been down for quite a while after a cras, and I finally just got new parts for it. FOr some reason though about when its starting to get where I can slide it around, it starts shaking horribly. Once it gets off the ground I have a very hard time controlling it, any ideas? i think the blades might be out of track, but I cant tell which to adjust because its just one big blur, and the taped blade appears to be on both the top and the bottom. Im thinking about buying a pitch guage and checking it, but just wanting to try anything else before I can get to the LHS to buy one.

Thanks in advance,
John

Check your feather shaft I bet its bent. Take off the blades put a allen wrench on the shaft inside the blade grip and turn it if its bent the grips will move up and down as you spin it.

I have a falcon 40 electric after a crash I had this horrible vibration got it back in tested it. started takeing it apart and realized the rotor head core where it attached to the rotor had sheered off and had to be replaced maybe see if its something along those lines. with that broke it makes a dramatic difference.. good luck mike
