Welcome to Club SAITO !

OK I have been watching a Greek build an 1/4 scale version of one of my plane projects on YouTube for a while. In the latest installment you get to see what engine he selected. I thought you guys might like to see. Skip to about 23 secs. will show the engine. My 1/5th scale will require me to scare up a Saito .91 or 1.00.

I'm sure you are not the only one feeling that way. I wonder how many guys are making up a bogus FAA number and putting it on all their airplanes so the locals got a number to look at? I haven't heard a database they can run the numbers through to check them. I think the FAA number is more for the appearance of doing something then doing something worthwhile.
Build, build build !
BTW, I did enjoy the video link. Sure beats buying off the shelf!

FA-100 is an oddball size. Much taller, (7mm) than the FA-115 and requires a wider mount.
The only proprietary parts are the crank and the piston. Everything else is common with other engines.

So I just installed a new set of rc bearings in my Saito 72 and there is a little slop in the main bearing. I can hear it. I wiggle the crankshaft from the front and it sounds like it’s coming from the main bearing. My gut tells me this is unacceptable. Should I order some higher quality boca bearings or go with what I have? Thoughts?

That is the very reason I don't use RCBearings, I ordered a set about 15 years ago or so for my friends Webra SilverLine 61 and I think the new ones were looser than ones I removed. Never again did I do that.
Boca Bearings for me only.

I got some from an eBay seller that were horrible. Tossed them all but did get a full refund.

Look for an FA-115, it fits the same footprint as the FA-91S, FA-80 and FA-65. ( 2-stroke 60 size mount) And, it is only 2mm taller and 1mm longer than the FA-91S. More power than the FA-100 too.

The seller said he was a rc bearings distributer. Basically, they’re crap.
I just found a Boca 6902RS in my stash that’s that same size as the main bearing. It’s a sealed bearing so I’ll pry off both seals and install it. The front bearing seems ok to me.
Wow,
I will let him know he just got a very bad review!
Never had a problem with the bearings or the service. I always assess clearances before installing new bearings.
Still buy most bearings locally in name brand boxes. Some folks don't want to pay that price though

So Gary, make that three bad reviews. Tell Paul whatever you like. He can come here and tell me how full of #$%^ I am but I'm tired of tearing down engines to replace bearings after 10 tanks of fuel.

Well I don’t mean to bad mouth anyone. Not sure if the eBay seller is Paul or not but he did respond to my question and shipped my bearings promptly. I can’t complain about the service but the product is not good quality.
I guess I’ll stick with Boca from here on out.

Most the time Paul is quick to respond. He forgot about me for 3 weeks after multiple emails one time but everyone can forget from time to time. No bad marks for customer service for me. I dont bad mouth people either, just products or customer service.

One thing I didn’t mention before is that the inner race on the new main bearing seems to be slightly narrower as well. The reason I say that is when I put the bearing on the crankshaft the outer race would rub on the counterweight. The original bearing wouldn’t do that. Also, in the picture you may notice the inner race is a littler thinner than the original bearing.

They aren't necessarily junk bearings, thay are the wrong bearings.
