RAH-66 Comanche maintenance event.

It’s time to get aircraft ready for the flying season. Most in the hangar are ready for the season however “Homer” likes a little more maintenance than the others. With running duel motors, and ESC’s along with all the parts to hook everything together and then, for it all to actually work as one harmonious flying machine has been a daunting task.

This is actually my second Comanche. The first one was nitro powered. It looked great but lacked in performance. It would hover around but lacked in tail authority to become a viable flying machine. It ultimately met its demise which was a god send.

I was able to acquire another fuse from Joe Howard about 15 years ago. I set it on the shelf and began thinking of all the things that did not work and how to make changes to make it work.

This machine has been flying for 13 years. Over this years I do the annual maintenance around this time. It is a very solid running and flying heli but does require a little more attention than most. I figured I would share this maintenance event with my fellow modelers so you can get an inside look at what make this thing work.

Hope you all enjoy and thanks for dropping by,

I was pretty busy over the weekend on Comanche. Everything looked very good. The motor and gear box bearings were replaced and the shaft bearings were inspected and lubed. The grip bearing were inspected and lubed. Cleaned and inspected re-shimmed the TGB gears from .27mm to .30mm to take out some end play from the new bearing install. All the bearing on the pitch control assemble replaced lined and re assembled.

Replaced main motor bearings waiting for a replacement motor shaft. Inspected and lubed all main shaft bearings.
