90% normal is better than most of society. My mother just had hip replacement surgery, she complained that the food in the rehab center is bad. She must be doing well if that is her main complaint.

Default Saito 300

I recently picked up a conversion kit from C&H ignitions and am wondering if there are any threads on the conversion process.Also wondering if one needs a puller to get the prop driver off a 300 T.Any info is appreciated..Thanks Steve

I don't think you need to removed the prop driver to use the C&H conversion kit. w8ye and BLW can show you some pullers though.

You do have to pull the prop driver,because the magnetic ring slides over the back of it....

Steve, there are references to pullers all through this thread, I know it's kind of a pain to hunt for them though. I am going to do my 1.50 but will need a new prop driver as I did a home made and mine has a rare earth magnet buried in it. My home made bracket is not adjustable without making a new bracket.

The puller is overkill, but it's the only pic I could find when I got it. Mine is more simple (and cheaper). The tools do the job without a problem. I think both puller and bearing separator were in the $40 range at Harbor Freight.




Almost forgot, the last time I used this pic someone pointed out the 3 arms are backwards for the job of pulling thrust washers.

Sorry for the low light focus quality. This shows the separator in place and then the puller positioned and ready to crank off the thrust washer.

I am almost finished swapping my Tiger 60 from being Fox .74 Diesel powered to Saito .80 powered. I had to rig up one of my home grown swing lever throttles without much room to do so. As you can see the engine compartment isn't very large. I had to keep things tight. Both the Saito .80 and the Toger 60 are skinned up, the plane is about 12 years old and the Saito is about 24 years old give or take a couple of years..

Nice work, Hobbsy.
That TurboHeader looks exotic.
Does the swing lever throttle add any slop to the linkage, being that you have 4 connections instead of 2?
What are you going to do with the Fox 74 diesel?
(Sorry, I have an inquiring mind today)

Thanks HS, I carefully selected a 2mm control rod and I have some 2mm Sullivan connectors, the Sullivan connector fits the throttle lever precisely . I used a Z bender to put a Z in the 2mm rod and it fits the hole in the servo arm that serves as the swing lever. It's all very precise and nearly friction free. The is a thin piece of fuel tubing in the servo arm splined hole that serves as a bushing, by tightening or loosening the screw in the servo arm I can adjust how precise and add a little tension to it to control any shaking. I must be a degree less engineer. I love to tinker. I should probably paint that Saito again, I chose a poor paint the last time.

PS, the Fox is sitting in a box with Corrosion X in it.

Adrian is working on 5 & 7 cylinder versions of his single sensor/module CDI.

It is based on the same principle as the Saito FG84 system.

You need to contact Adrian as he has many products that are not listed on the C&H website.

A couple of things. On the week end I went to the field to sniff nitro and ether and indulge in the usual talk fest. Any way my old flying mate, new 91 well run in and installed in a World Models Midget Mustang. Only varience from standard was an OS F plug. Running 20% synthetic oil and 10% nitro (the wimp). Any way after a good session (previous week) on this day a/c lacked power. Ah you say needs HS and maybe LS needle adjustments. Partially right and after much stuffing around with such things as remote glo system and carby adjustments etc the plug was pulled. What was a new plug the previous week was now dirty and crappy, new Saito plug fitted and a/c flys like a dream. Never seen a plug (new) die that quickly before.
Re the throttle stand off. Ever since I found my first Dubro catalogue while workin in Malaysia, I always look there for cost effective/time saving solutions. In this case I would have used a 4 stroke throttle stand off, cheap effective easy to install but not as satisfying (engineering wise) as making your own.

On pullers, the name eludes me but there is a Yank after market mob that makes all sorts of specialist tools (for automobiles) including pullers and seperators that really fit the bill for us tinkers. TRW or ARW I think, come in blister packs and white and blue packaging. For people in OZ try Coles or A.I.S.

C&H sells CDI conversions that can be used with either glow fuel or gasoline. A full gasoline conversion uses a different carburetor.

I prefer to use glow fuel with CDI as methanol has a potential for about 25% more power compared to gasoline.

Converting to CDI with glow fuel will result in a 20% improvement in fuel economy while increasing power slightly over glow ignition when the same glow fuel is employed.

I'm about to come into possession of a 2.70 Saito twin. Does anyone have a scanned copy of the manual?

Bob, this is maybe even better, Clarence Lee's test of it.
