T-REX 600 › T-Rex 600 - Main Gear Rubbing on tail Drive Gear

I have just replaced the main and small tail drive gears (one that belt is connected to) and have found that the two are rubbing together and producing a fine white powder.

I have got the spacer in between main and smaller one way bearing mounted gears, have checked the main shaft collar. What is going on with this? Is this a known problem? Had the heli for over 2 years and nevr had a problem. Also replaced main shaft, feathering shaft and all supporting bearings so this is all very strange.

Anyone got a suggestion for a cure?

TIA

I've had white powder on every electric I've had. Some are better, some are worse depending on the type of pinion that you use.

Your one way bearing has migrated up a little in your hub, if you have the tool reset it, just found mine the same way happens over time!

Update - works perfectly after adjusting the depth of the one-way bearing. Certainly something to keep an eye on when replacing one way bearings in the future. Thanks!
