Default Magnum Center-Glide for OS 105 experience

Good morning everyone,
I'm considering doing the Centerglide conversion for an OS 105hz-R.

Hoping to hear if there are any negative effects of having the process done, and how long the Centerglide will last (number of gallons?).

Someone on YouTube indicated they had power/tuning issues after the Centerglide was installed, so hoping to see if that was 'user error', or if there was a downside.

I'm hoping reduce a big maintenance item from my nitro helis by doing the Centerglide conversion.

Any thoughts/experience/advice would be welcomed.

I heard they are pretty expensive for the larger motors.

I don't know if it is herd mentality or not, but it seems that everyone that bought them says they love them and they last "forever".

I don't have any plans to use one.

CONS

- People have had tuning and running issues. It's due to not having the right tolerance in the bushing.

- After a while you'll notice crank wear right where the crank sits in the bushing (crank will need replacing).

- Expensive and have to send the engine out

- No telling how long Buzz is going to be around to continue to provide his services. Already hard trying to get a hold of him.



PRO

- If it's perfect, you can run many cases of fuel maint free without worrying about the main bearing letting go.

I don't have any 1.05 engines but I do run the .55. On my nitros I just replace the rear bearing before I run them with a very high quality ceramic bearing. Once I do that I've never had a bearing failure. My current .55 has about 500 flights and is still going strong on its ceramic bearing.

Interesting - how much time do you have on the ceramic bearings? 2 years? 4 years?

Also, I see you are in Houston. Have you stores the helis in climate controlled environment?

I'll be moving back to Houston shortly, and my helis will likely be kept in a non-climate controlled garage.

My current .55 is going on about 5 years and on its first set of ceramic bearings. I think the bearings were about $60 from Boca.

I store my helis in my garage. Its not climate controlled. My nitros get flown most weeks. If I have to store for a long time I do use some marvel mystery oil in the engine.
