Good mate-up Dave. Any plane under the control of a green transmitter has to fly well. The Saito "Hobbsy Special" will serve proudly for you.


The LT-40 here is FA-72 powered, spent most of the last twenty years hauling around pontoons over a nearby lake. Plenty of power.

Now, get busy and start wearing it out!

Default Spinner nut?

I know this is an old thread and all my fourstrokes bar one are Saito and on every plane I use them with an aluminium back plate spinner except one which I have a Saito 62 with 12x6 three blade prop, the exact set up youo have on your bright yellow plane here in the photograph. But can I ask you this question, in all my 38 years of flying rc planes I've never used a spinner nut on a Saito engine. But this particular plane I have now with the Saito 62 and three blade prop I have it secured with the prop nut and locking nut. It makes it a wee bit more difficult to use the electric starter. So do you go without using the locking nut and just screw on the spinner nut over the top of the prop nut? If so , is this a safe set up? Would it throw the prop? I'm very safety conscious and would like your opinion? Kind regards Aidan.

Hi there, do you just use a spinner nut over the prop nut and disregard the locking nut? If so, is this a safe set up? I would like your opinion as I am very safety conscious. Kind regards Aidan

When using a Spinner Nut I don't use the original prop nut or lock nut. I just tighten the spinner nut against the prop washer. Tight TIGHT!

There's little chance of it coming loose unless the engine is over primed at startup or run too lean at wot.

Many thanks. I have my Saito 62 on the Calmato Sports 40. Flys it very well.

Nice looking setup. The Saito FA-62 is a good match for the Calmato 40. I like your use of ball links.

A couple of friendly tips:

It's a good idea to secure the crankcase vent tubing to something. Clamped to the firewall with an inch of tubing extending below the fuse works well. Some prefer to route that vent to the muffler tail piece, via a clamped on piece of brass tubing, so the exhaust stream carries away the oil.

For a better looking exhaust sealant, teflon based plumbers paste (cheap) works good as does Swak paste (more expensive). I actually prefer Swak but I've been having satisfactory results with plumber's paste (RectorSeal T plus 2"). The excess can be wiped off after the exhaust is tightened leaving a robust, leak free, tidy looking engine.

Many thanks for those useful tips. In relation to the crankcase vent tubing, that only stays on when I'm not flying and has a fuel plug stopper at the end. When I go to the flying field for a days flying I simply remove the fuel tubing and at the end of the day put it back on again. The orange gasket maker sealant I bought in America. I've tried everything over the years and I found that this stuff works great and I've never had a muffler come loose in over 20 years using permatex. I'm just recently bought a turbo header for my Saito 72 and look forward to trying that out. In all my Saito fourstrokes I have everyone connected up to the throttle servo using the Dubro Fourstroke Throttle Linkage System. It works great.

This is the Calmato flying just over a year ago with the Saito 62.

Your very welcome. The Calmato has not been out since then as I have been flying some of my other planes. But the next time I go to the field I'm taking it with me as its due a few flights. Thanks for watching. Kind regards Aidan

Default Whistling Calmato 40

Amazing speed with only an FA-56.

The 56 is a real torquer, I have images of one, (that I can't post) turning an HY 12 x 6 at 10,008 and a Xoar 12 x 6 at 10,001 rpm. Also one image of it idling at 1,370. Hooraw, I gottem to post.

Brilliant and great landing also. The Calmato 40 is a nice sports plane and is ideal for the Saito 56.

It appears that someone has stolen the name.

Default Saito 62

This float plane from 12 years ago has the Saito 62 on board. The same Saito 62 which is now on my Calmato 12 years later. In all those years ive never had to do a thing to the engine other than put fuel in it and start it up. Its still got the original glow plug .

Nice, Aidan. Thanks for the vid.

The 62 is running plenty rich in both vids. Saitos will run seemingly forever tuned like that.

Thanks Glowgeek for your kind comments. I like to run all my Saito engines rich and I like to see a smoke trail.

What prop were you using when making that 1370 RPM idle ?

To be honest, I do run my Saitos a bit leaner, both needles, but still within an acceptable mixture range. I adjust the high speed needle as lean as I can without sagging on extended uplines. The low speed needle gets adjusted lean enough for 20-30 seconds of reliable idle before the rpm starts to drop. Both needle adjustment are performed with the engine at full operating temp. And guess what? The engines still last seemingly forever.

Granted, most of my dozen or so Saitos are mounted to warbirds where I have a need for speed.

Good stuff. They are fantastic engines and give very little trouble.

Dave,
Do you recall what prop the Saito in your last pic was using when idling at 1370 RPM?
