Has anyone had the oneway bearing in the clutch fail?

Went out Wed. (day before Thanksgiving) and was able to start my Compass 3D+ once. after that, couldn't start the motor. The start shaft just spun without ingauging the clutch. The temp was around 40 degrees.

Once home and the heli warmed up, the oneway bearing in the clutch trys to grab, then let's go. I've ordered a new clutch hoping this will solve this issue.

Finally got around to replacing the clutch Friday night. Yep...the one way bearing is toast! I hope this doesn't become a habit! I couldn't help notice the clutch looks somewhat like an Align clutch. I'll have to check that out...

Dont know the heli but isnt that bearing a replaceable item without having to purchase a new clutch?

I'm not sure if I can order just the bearing. And if I could, I would need an arbor press to remove and install the bearing. So I ordered a new one.

I dare, I dare! Sorry...I could help myself!

Make sure that you wash any grease out of the one-way bearing and replace it with light oil.

The grease causes the rollers to stick, so sometimes none, or only some of the rollers engage. When only a few engage, they carry the entire load from the starter, so it is easy to break the one-way when starting.

Cold weather, I should think, would aggravate the situation as the grease would be even thicker in the cold.

Both the Auto clutch one-way and the starter clutch one-way should be lubed with light oil, only. Tri-Flow works well, too.

This is true for any model (found this on with auto clutches, back in the late 1970's or early 1980's).

Flew my Compass 3D+ Christmas Eve and Day! The new clutch works fine, even in this cold weather.

I had been flying my Protos 500 for a while and noticed a difference with the Compass. It's a lot slower... Now I wish I had bout the 6HV instead. I've become a electric junky. I really like the power from electrics, but the flight times are shorter and it takes time to recharge the batteries.
