I will be sure to lubricate the tail dirve wire. I will check and see what upgrades the heli has and determine what is needed then. I am told it has all the metal uprades offered, swashplate, head and tail dirve but we'll see.

I thik I will also disassemble most of the heli and loctite the bolts throughout.

Thanks so much for the info. Those links have some very helpful information.
