Here is a diagram from the manual. This is how it fits on the crankshaft. One side of the nut labeled #28 has a machined groove for the 'cone' section of #110. This is easy to reverse if you aren't paying attention.

Had me worried that I just had my Dad buy a bad motor. I found 2 82s on horizons site, one discontinued and the other not.

I have no idea about the crankcase, but you can tell the difference by the pictures.

It is just the old "A" version and the new "B" version

They redesigned the engine for the FG-14 and then they went back and changed the Saito 72 and 82 to be like the gas engine.

The cylinder and all the moving parts are the same in both versions

I am not a Saito expert, but I never heard of the Saito .82 having a crankcase problem in its original form. I suspect that the introduction of the B model has more to do with the introduction of the 14 cc gas/spark version. Why make two different crankcases when one will work for both versions? Just my $.02 worth.

Enjoy!!

Did the $300 also include servos? That is an awesome deal when you consider that the Rascal airframe alone cost $220. I bought mine 4 years ago before the price increase. Along with the Tower discount at the time, I got it for $185. They were a pricey ARF, but worth it.

the motor mount that is in place from the nitro motor. i was looking at the one that comes with it . its is nice but it is heaver than the hanger9

Status: offline 		Hello

I have a 72 thats about 3 years old and always worked fined but for some reason I could not get it to run under 5k rpms. The only way to do it was to keep the ignitor on but as soon as I removed it died. I tried new glow plug with no success. I haven't flown this plane for a little over a month now and I don't know if that can affect the engine. I tried to adjust the LS without success but I think that by know if too out of place, could anyone tell me what is the factory setting for the low speed needle so I can reset it.

Status: offline 		If its a plastic throttle arm set it about 1/16th inch inside the flat surface of the throttle, if it is a metal arm set it even with the end of the throttle barrel. Its easiest to set the LS with the HS needle at absolute peak. If you attempt to set the LS needle with the HS rich you end up chasing the needles all over the place. It will end up about where this one is.

Status: offline 		The Saito 200R3 is a very sweet motor and very forgiving. I set the initial high end at 4 turns out so the first 5 minutes would be very heavily lubricated. The motor started right up after using the built-in primer spout at the carburetor’s opening.

I am using the McDaniel ignition system so did not notice the #3 cylinder going cold at low RPMs. I did however test it after I ran the 4th 10 minute break-in run because of what I had read here. I removed the ignition system and started the engine with a glow starter; one cylinder at a time. The motor started at ~2500 RPM setting just as easy as if it were on all three. Then you just walk the igniter to the other cylinders (very carefully) and start the other two. I used an IR temperature gauge to judge who was running and how well. #1 and #2 ran between 150-170 degrees Fahrenheit depending on RPM. #3 would shut down and go to 90-110 after an idle below 2100 RPM. I could be running a little rich which could have caused this. I am running now at ~2-1/4 turns on the High Speed needle. All I know for sure is that problems with #3 never occurred with the ignition system. I now have the ignition set to come on at 1/3rd throttle and less and I’ve flown 6 flights (10-12 minutes each) without an issue.

I have several Saito radials and use an ignition on all of them. I never worry about an ignition on the singles even the 46 seems to work fine after started.

Hope this helps answer any questions posted or not.

Thanks,

jimm

The 0.015 decompression shims for the Saito 150 were once offered by C&H Electronics, but they are no longer in business. Anybody have a suggestion where they might now be found now and purchased?


You can contact Horizon Hobby Service department about these.  We still have them available.
