Have a Saito 100 appx 1 year old with lots of flights on it. When flying last week I noticed an unfamiliar noise coming from the engine.
Upon checking the prop hub for movement, I found there to be - up and down and side to side play in the prop shaft. I can only guess it may be do to the bearings going bad.

Has anyone had prior experience with bearings wearing out in Saito engines? If so, do you recommend replacing - or returning the engine to Horizon for servicing.

Thanks - Jaketab

Replace them. You can get replace ments from several dealers as well as from the engine manufacturers. Just pay attention to disassembly, if you get in trouble, start another thread. Or do a search, several threads on timing the valve train are found on RCUniverse.

Best deal on bearings are from McIntosh in Arizona. Great service and good advice.

From the sounds of things the bearings are very bad , you can change them yourself unless its a warranty deal.
To answer your question Yes I have notice bearing failures more in saitos than other brands ,but it seems like once there changed out to a good quality bearing there about the same .
rcbearings.com has your bearings in stock at a good price and you can also upgrade from the standard steel bearing and race to either Stainless or ceramic.

Let me asked you this,do you always run the engine dry after you get done flying for the day?
What fuel do you use ? %'s of oil and nitro .
Do you ever use afterun oil?

Any or all of these can lead to early bearing failure if not used correctly.

Go to "welcome to club saito" under glow engines, lots of good stuff there. Try a search on bearings.

I've seen 2 100's have bearing issues, mine was one of them. Replacement wasn't hard and I have had no issues with the engine since. From what I could glean from the Horizon rep I talked to there was apparently a bad batch of bearings that went into some of the 100's, they sent me mine for free when I asked for the part numbers so I could buy them through my LHS. To say I was impressed with the service would have been an understatement.

I would suggest that you simply call them and get a set sent to you and replace them yourself. Like has been said earlier there are plenty of threads on the board here that have pics and all the info necessary to perform the changeout yourself.

I replaced the bearings in my Saito 100 with stainless steel bearings from boca bearings and have had no trouble since. Regards, Scott.

Scott,


Everything is OK, except the price you had to pay...

If you had gone shopping, [link=http://rc-bearings.com]RC-Bearings[/link] and Paul McIntosh, as noted by others, would have made a much better deal for you.

The same items, at just 1/2-1/3 of Boca's price.

Has anyone ordered bearings from RC-Bearings?

I have been buying bearings from RC_Bearings since Paul was still in England, I have used no other source since.

Paul McIntosh (RC_Bearings) is on RCU as “DesertSkyModels.

replace the bearings and you should be ok. also check the crankshaft end of your conrod, the bottom big end can get worn by the loose crankshaft not staying aligned during running. mine was loose in june 206 when my bearings packed up and i had to replace it as well because the bottom of the conrod was just starting to rub the bottom of the crankcase which could have led to disastrous results had i not noticed it in time. all fixed up and running perfect now.

If you do not feel OK with changing them then just hollar at us. I for one would be glad change them for you. It's really easy if you are good with stuff like that.. The rc bearings have instructions on how to change them. That is a 100 for you. I have changed 3 100s already. Change them to ceramic and you won't have to do it again.. and it's just pennys more..
