The beginnings of a diesel conversion maybe? Must have a very long connecting rod.

I've been doing both, throttle servo slow down and wot travel limiting for some time now on my gassers. Neither are my idea, both work great, especially slowing the throttle servo to match spool up time.

Hi Rob, welcome. There are several R3 R5 users that visit this thread from time to time. One of them runs all of his multicylinder Saitos on glow ignition with good results. Maybe he will chime in. One thing for sure, don't make any rash decisions about how your R3 runs until it's fully broken in, things change along the way.

I think this is the guy who intends to make a larger diameter to the overall on a FA 325 R5. He was hoping to extend the cylinders to accomplish it. It has been an interesting thread. Lots of nay sayers. And what the heck comments. I for one applaud his foray into the unnecessary.
He is pretty deep in that water.

I know, just didn't want to volunteer you for the onslaught of questions.

Thanks ! I have a FA90T as well,, lot of people warned me about it due to tuning,,
what I discovered is that the secret was in setting the valves very carefully it runs like a dream..

RoKit

Thank you !
Have been running the engine on a stand for about 1.5 liter fuel (5% nitro) about 1.5 hours +/-
this far it is tuned to about 1800---8700rpm with a 16x8 MAS prop. The peak rpm was 9300+ and then I opened the needle another 1/4 turn.
So all in all I am happy except for the temp diff I can feel touching the cylinders, no1 is like "normal hot" while 2 and 3 is less than warm.
I did order a Morris mini motors ignition last week, thinking that it will make the engine run smoother and prolong its life.

My plan is to mount the engine in a plane with ignition, monitor/log the temps and go from there.

My 120R3 runs like that too. The upper receives less fuel and oil than the lower two, so it runs hotter. It's a balancing act to provide a rich enough mixture for the top cylinder while still lean enough for a decent top end. I have been too busy with house and truck work to get the Corsair out and run up again. Last time I tried I found the fuel system setup didn't work well, the fill valve was damaged, so I took it all apart and made it a 3 line set up, and hopefully this time I can get fuel in the tank and get it running.

Good AM to my Saito buds, I have been tatoo'd with 1/16" black dots that will serve as targets for the radiology gun in a couple of days, then 8 weeks, 5 days per week of treatments. The Eligard shot I had reduces testosterone production to the extent that you are left sluggish and tire quickly. Not much macho in that.

Hey Mike, send me a couple of 65's to rebuild so I can have some easy fun. Thanks

Well Dave get a black texture pen and join all those tattoo dots together to fill time in in the waiting room, bit of imagination and you could have yourself a (cough) harley there hey! maybe even an fa125

Just about on my way round aussie in the van so thought I'd brush up on the baking skills.

And a bit of Monty Python humour.

RoKit

Good to know I am not alone..
Having a big difference in temps..

Not sure what it means in the long run.

1200SportsterRider

Thanks Pete, for the morning laugh.
Trouble is, those dots are in a perfectly straight line, one low down on my abdomen and one on each hip.

If you fellers didn't check those useless temperatures you would not need to worry.

Captcrunch44

ok my friend I will.

1200SportsterRider

Great, I look forward to it. Many Thanks

Hang in there Dave, Silly Question tho - would rotating the mount 120 degrees help?

Hah discovered another use for the laser. I cut and etched some 1/4" acrylic and found that I can melt pigment into the etchings with the laser. I just have to get some powder coat paint and give it a try. Just have to remember to turn the air assist off or there would be a cloud of dust instead of melted paint. Now to find what is used to bond acrylic to itself so I can make some motor stands for my Saito engines. These will be cool as cool can be too.

Now that is a handy list! Thank you!

1200SportsterRider

You're welcome. Horizon has that code system badly botched up at the moment, I hope they straighten it out.

1200SportsterRider

Horizon has the Saito FA 40-a in stock: https://www.horizonhobby.com/product.../SAIE040A.html

Their 10 x 4 prop recommendation is ridiculous. Here is my FA 40-a turning an 11 x 6.
