So I use a hanger 9 starter with a 4 cell LiPo.
I sent him same set up. He puts 4 cell pack in something else and tryís to use a whole bunch of different battery combinations that didnít work so he buys big ass magnum something starter puts a 4 cell Lipo on it and now he can start his engines But allís is trying to start 30cc size engineís.

the plane is some sort of vintage race plane that had floats. That were taken off to be a land based plane.
and yes we filed a 337 with the FAA

I pulled the 4*60 wing down to replace the retracts, and will need to beef up the pivot brackets, they broke loose. Still need to get the Saito 90 run up, haven't started it since I got it. I think it will run.

Might not be a terrible idea to open it and check for rust real quick? Nice engines but they all hate rust.

I killed a used 56 and a 62 due to rust. They both felt pretty smooth before I started them. Just say'n.

Already took it apart and cleaned it, everything looked good, just a bit gummy from Castor.

Anyone have an idea how much run time a Saito .50 will get at 3/4 throttle with a 6 oz tank?

I've run an fa45 for 20 min on an 8oz tank with varying midrange throttle and a few wot passes. Plenty of fuel left for landing. I'm guessing here but I think an fa50 would run 12min or so at 3/4 throttle on an 8 oz tank. A lot of that has to do with needle settings though. Recommended tank size 10-12oz.

I know what an FG-11 with a 12oz tank will do. About an hour or more.

Thanks! I was trying to decide what size tank I need for my Tiger 2 if I put a Saito .50 on it.

An FA50 will fly it, an FA62 will wake it up and reveal it's true potential. Just my take on it. Most people fly them with ,46 to .55 size 2 strokes which both make a great deal more power than a .50 4 stroke. Again, just my preference.

Measure the OD of your header?

If you don't have the header it's trickier. Measure the inside diameter of the exhaust port and then add 2.17mm and then round up or down to the closest mm.

For thread pitch: count how many full threads there are in a 10mm length of threading. If there's 10 full threads then it's a 1mm thread pitch. If there's 8 full threads then it's a 1.25mm thread pitch.

The FA45S thru FA62 has 10x1 thread and the FA65 tru FA100 has 12x1 threads. My 170R3 has 10x1 threads. I'm guessing the 200R3 is 12x1

Here is a Tech note from MacGregors: Muffler (Left) for Saito FA-170R3 and FA-200R3 Four-Stroke Radial Glow Engines.


A picture for proper installation.

Tower Hobbies specs for the 200R3 state that the muffler threading is M12x1.

Looks like Triumphman made a good educated guess?

Here is from the 200 manual

Bore: 1.06 in (27.0mm) Crankshaft Threads: 8 x 1.25mm Cylinder Type: AAC Cylinders: Radial Displacement: 2.00 cu. in. (32.98 cc),2.00 cu. in. (32.98 cc) Engine (Only) Weight: 46.4 oz (1366 gms),46.4 oz (1366 gms) Muffler Type: 10mm Flex Exhaust Pipes included Muffler Weight: 4.4 oz (125 gms) Prop Range: 16 x 8-10 17 x 6-8 Recommended Fuel: Glow Stroke: 0.76 in (19.2mm),0.76 in (19.2mm) Total Weight: 50.8 oz (1440 gms),50.8 oz (1440 gms)

I think the 12 mm is for the gas engine with the black elbow adapters.

Engine run, home brew Saito 50 GK made from spare parts, new crankcase.

Plug===Glo-Devil 4c Special for Saito and Enya
Exhaust Early Cast

It has a great, clean midrange. I didn't expect 10 +.

Ignore picture #2, it's a different engine.

That is a very respectable performance on the .50!

Same thing happened to me when I ran Crunchy's 50. Over 10k with a 12x6 is FA56 territory! IIRC, his 50 was only 100 rpm shy of the last 56 I had.

I can't remember, does the 50 have the fuel metering slot at the back of the throttle barrel? All the ones I've run that had that had a clean midrange.

Thanks Mike, I sent a slightly stronger 50 to a friend yesterday, I hope that guy's tach reads like mine.

Lon, I've never seen what you describe as a slot in the back end of the barrel, except on a 65.. You happen to have a picture.

Yeah, that's it Dave. I guess I must remember that from the 65's. Best carb ever, wish they were all like that.
