clutch bell bearing

[Mike Spano]

where do you store the heli? nitros really need to be stored in a conditioned space to keep humidity out of the motor. I always ensure my throttle is totally closed and piston at blocking the exhaust port when I am not flying them. I also do not run my motors dry, I simply turn them off and leave them be.

I keep them in the Basement the humidity is at 40 %, I don't run them dry jut shut them off.
I was reading on an OS forum that some guys were having bearing problems also, they were the OS 55HZR limited.
That is the engine I run in two of my helis, haven't had problems with the other one!

[Mike Spano]

Yea, I typically change bearings in my 55hzr 2 times a year. Maybe 3 depending on the circumstances. My 105 on the other hand can go all season on a set (I fly roughly 10 flights on my n5c to every 1 flight on my n7). Try keeping your heli in a closet on a conditioned level of your home. Just wipe it down well and stick a paper towel in the pipe and be sure your carb is closed and you won't have any issues. The alcohol in the fuel will wick moisture in the air straight into the bearings. If that's not possible, consider a center Glide bushing.

I hope this solves my rattle problem, I hope to try it Saturday weather permitting.
Thanks for all help Mike, and everybody else that chimed in.

The humidity here turns nitro into rust soup if left for too long. If mine is going to sit for a while I pull the back plate and put after run oil directly on the rear bearing and also on top of the piston through the glow plug hole. Put the back plate back on, make sure fuel line is pinched, pressure line disconnected, hold a paper towel over the glow plug hole and turn it over a second or two with my starter to make sure the ring gets coated. It's stayed in pretty good shape for a long while now. When I'm flying every day/every other day I don't worry about it.

I try to oil my helis up if there going to sit longer than two weeks, I also plug the exhaust pipe with paper towel.
For winter storage I pull the engines out, clean them up and use lots of oil. I have only had one other set of bearings  do that on me.
I keep the whole house at 40% humidity year round, so that shouldn't be a problem.

[Tim J]

I was able to get out for a bit today  with my N5c, the new engine bearings did the trick.
 it sound's Awesome without the rattle.

[Mike Spano]

awesome. was the cage broken? I had one do that to me one time and it rattled. that is a little rare though.

[Tim J]

No the cage was fine just rough when turning it in my fingers.

[Mike Spano]

got ya.

I go through rear bearings regularly here in the Mid-West as during the flying season there is a lot of moisture in the air and since my heli's usually live in my truck the temp swings are just a fact of life for me. I do run them till they wont fire on the glow before storage. I might have to check out the Magnum Centerglide bearing out and see if that's the cure. I am too lazy to pull the bottom plate off my N7 an my N5c is easier but laziness prevails. I have a box full of new bearings to chew through 1st though.

[Tim J]

I was looking at the Magnum Centerglide bearing also, didn't know that was even an option for these engines.
Going to give them a call this winter, just to see what takes place.
 I pull my engines out clean and oil them faithfully, when I'm finished flying for the season.

Centerglide bearing is the ticket. Defiantly worth the money.
