Hi,just rebuilt my gas Pred.With the usual new bits,mainshaft,spindle,blade grips,bearings etc.
I've noticed bad vibes on the heli now,should the yoke run true?,viewed from the above.mine doesnt,real obvious at spoolup and down.i cant honestly remember before the crash as it was a new built kit.
it appears like a bent mainshaft,but the shaft seems ok.
Blade tracking is spot on too.Blade balance is good also.
One of the two small bolts,in the base,side, of the head yoke, snapped while undoing it during the stripping down and is stuck in,unable to loosen or tighten.
i just put a new one in the other side and tightened it,asuming it would fit snug as before.
any advise please?
