Been flying my T-Rex for a month now, What maintaince should I be doing/looking out for?
I am keeping my eye on the belt, bolts, gear mesh, blade condition, and battery balance.

Are there things I should be lubing?

Since I did not build the head or tail assemblies, is there something in there I should be checking?

Any thing would help as this is a NICE helicopter and I wish to keep it that way!

TIA

Foist and foremost, the poor tail shaft will moan a little if you lube her spinners. Use something like 3-In-one oil, or similar viscosity (thinner would be better than nuttin), prop the boid on its side, supply a drop in the pocket of each bearing and let sit. If in doubt, flip her over and do the other side, later. Wipe up excess. You can do all the bearings like this, but if you use dinosaur oil, you don't really want to let it weep through the grips and reach the dampers/o-rings. TP and Q-tips can clean her up all nice and purty-like when yer done. Ideally, the bearing sides should be wiped completely clean before lubing, to prevent any grit from migrating down into the little beasties.

In addition, check the main & tail shaft bearings & lube them.The Align bearings aren't very good, I've replaced the main bearings after about 5 flying hours.You'll need to remove the head & main shaft to check them well.At that time relube the one-way bearing.The one-ways seem to hold up well.

I had a couple of one way bearings break on me. I noticed the tail drive gear would always seem to get stuck with the main gear. In other words, the head wouldn't free spin after applying thrust to them. I replaced the sleeve lubed the snot out of it and finally got a new bearing installed. The last solution worked. Not a peep yet (knock on wood)

check all the links connected to the head unit.

check to see that all screws are snug on the head unit.

make sure the screws to the motor are still on tight

check the belt for wear, some are lucky and they last awhile, while some have belts that don't last too long.

Take off main blades and make sure that the allen bolts are still tight on the feathering shaft.

while either on throttle lock or having 2 wires of the motor disconnected, double check your pitch for all modes of flying and that none of your servos bind in extreme stick positions.

confirm that your speed controller is programmed as you wanted it to be and that throttle hold actually works.
