RE: Welcome to Club SAITO !
Hello Saito experts. I have a unique engine failure situation on my work bench. Firstly the engine is not mine. It belongs to a fellow club member. It is a Saito .56 and in flight the engine suddenly stopped. So violently that the spinner nut almost spun itself off. Upon disassembly and inspection it was found that the engine had dropped a valve. (guessing valve retainer failure) The valve of course bent and pushed out the bronze valve guide, broke the rocker arm and cracked the piston putting the repair bill (parts only) at $124.63 plus shipping. Unfortunately he is not the first owner of this engine and has no reciept of purchace. So does anyone have any ideas as to how he can repair this for a more reasonable price or did he just make a cool paper weight?

I have a Saito FA 100. I am new to Saitos and am in need of adjustment advice.
I adjusted the inset screw on my engine when I was changing the orientation of the throttle. What is the starting adjustment on this screw? Thanks for a reply, Stan

[&o]I had a used .56 and was sorry to put it down. May still have some of the bones? Is the cylinder wall damaged by the piston ? My cylinder was totaly used up. The piston was rocking inside, even with a new ring and piston !

That is too rich on the Saitos with the plastic arm. After you get it running and adjust for proper mixture the screw is a little below the surface of the plastic arm

Thanks for the reply and explanation. I also have a H9 Sop Camel waiting for an engine. Maybe I should put the 90T on this instead of the Skybolt.

The Cylender is a wash simply due to the destruction of the bronze valve guide. They do not sell it seperately. However if you have all the other parts and all that would need to be purchaced is a cylender head then my buddy may save the engine. I look forward to hearing from you.

RE: Welcome to Club SAITO !
I have now reassembled my saito 100 and have the vavles set at .002 and the thing vibrates bad! When i loosen the valves to .008-.010 it smoothes out great! Why??????? Thanks

RE: Welcome to Club SAITO !
It is not making as much power with the valves opened up
The timing may be off a tooth? Can you check it by checking that the overlap position is at top dead center?

Anyone know where I can find a prop nut for my Saito .91 that goes into a Corsair?

Good call! Thanks.
I had found:

but the Higley looks better methinks, and the price is right!

The 90T pulls that plane around just fine and has some to spare. Keleo has a 90T exhaust for $50 that sounds great and puts the pipes right where you want em out the bottom.
If you have all the wing wires installed I would highly recommend passing a safty wire through the eye of one of the turn-buckle screws, then thru the turn-buckle, then the other eye and fastening. Even with the lock nut these have a way of loosening and then you loose the turn-buckle. (Especially with the 90T) Also the flapping wire and t-b screw pokes holes in your covering. Not my personal experience, Just advice well heeded from another menber...I used 22ga from some scavenged alarm or phone wire. Bread ties with the covering stripped off works, too.

I do not know if your engine is repairable but to give your situation some reality, price out the cost of individual parts to repair this engine. I'm sure that you will find that the total cost of indiviual parts is not worth trying to repair the engine and that it is more cost effective to just buy a new engine. You can get cost data at www.horizonhobbies.com

Check the 4 stroke 4 sale board and fleabay .56's show up on there all the time at about $100. even if you have to replace the bearings and ring that's only another $25 or just put the top end from the "new" used motor on the old bottom end.

Tell your friend to look at the buy-sell section, engines-4 stroke under the RCU home page. You can find some new saito 56 for about $175

It's been some time since I last visited club saito. Good to be back here again.
Anyway, I need to make a grip washer that goes between the thrust washer and spinner backplate of my Saito 125 (the serrations on the thrust washer has worn off). What would be the best type and grit size of sandpaper to use, and what type of glue is best to glue the discs back-to-back?

RE: Welcome to Club SAITO !
Hello folks. I need a little advice. I have a Saito 100 on a Hangar 9 60 Corsair. I have the low speed tuned in and I have the high speed a few hundred rpm's off of peak. This engine has about 1 1/2 gallons through it. I am running the H9 plug, 15% Byrons w/16% oil, APC 14x8 prop yesterday but problem is with any prop I've tried. I am in Oklahoma.
Problem is, it runs great, leaves a nice little smoke trail, no complaints with it at all except in a fairly steep dive at full throttle it will cough, and it even sounds like it has died but then it comes back to life and I pull the throttle back and everything is fine. My question is, what is causing this coughing, nearly flaming out on me at high speed? I have a Saito 91 that has never done that in 10 years.
Thanks for any advice.

I checked the clunk and it looks good. If I back off of FULL throttle just a shade so that the engine doesn't hit top rpm in the dive it doesn't cough. It's when it hits that max rpm that it happens. The rest of the time it runs great. No problems at all in level full throttle flight or even in a dive if I back off the throttle just a shade. I just hate having to back off when what I'm trying to do is go Fast!
I wonder if a tiny air leak somewhere might cause it. I was hoping someone had encountered this before. I can't read all these posts to see if they have. Thanks for the help, and I welcome anyone who has experienced this before.

Bones,
Some tank kits that come with ARF's has fairly stiff tubing for the clunk. This prevents the clunk from following the fuel. If it only happens in a steep dive, I would make sure this is not the case.
