Hi Rob,
I have never heard of head loaders. I think the true set up would be to actually hover to load the motor. Not sort of a load simulation but the real thing.
I could have straightened the mast and feathering shaft in my lathe with a dial indicator but had the parts and prefer to install new parts. I know of people who do scary things with helicopter parts, even blades!
What I don't like most about the shaft driven t/r is that after a boom strike, one needs to replace the expensive shaft., Eliminating boom strikes of course is the thing to do! Duh - - - - , fly the thing , not let if fly me!!
For tracking, I use a short of black electrical tape on the target blade, remove it after tracking.
It seems parts for the Trex 600N are getting more available plus are in line with parts prices for the Raptor and Falcon. I really like the Trex stacked frame for easier maintenance, like the Trex 450.

Thanks Rob,

Spence
