I was looking for an engine to run while taking a break from gardening. Saito 50 GK in new crankcase, new bearings and new rig. A one hour run used 8 OZ of fuel. I mounted an Iron Bay regulator just to exercise it. The crankcase is set up for front vent, the back plate is the original with the rear vent. The front vent opening is plugged with a same size grub screw.
Saito 50 GK
Fuel======Wildcat 10% full syn.
Glow Plug==Glo-Devil 4c for Saito and Enya
Exhaust===Stock Cast pre-revised revised by me.
Prop======XOAR 12 x 6
Max rpm===10,130, 10,110 shown after 45 minutes run time at various rpm mostly above 5,000.
Idle========1,810
I engrave the muffler size on them.

I wanted to run up some today, but its cold and raining. grrrr. Yesterday was nice, but I had work to get done, like maintenance on the JD x500, and getting the grass it's first mowing, which takes a couple hours even with two mowers going. By the time I was done, all the lifting and bending and rough ground bouncing me around killed my back. So today, just going to go to my shop and replace the motor mounts on the SSE and call it ready for maiden. Maybe put the drawer handles on the workbench and give the drawer fronts a coat of Minwax. Then maybe get around to organizing the work benches now that I have drawers to put stuff in. I also have two doors to find hinges for to mount on the workbench.

Cold here also, I am going to do some rearranging also, I am going to move and maybe remove my larger band saw that has 9" wheels, mount my lathe in it's spot and build dedicated drawer for all the lathe accessories, and there are a lot of them. And the lathe will have it's own vacuum cleaner. I rarely use the big band saw but use the small one a lot.

My Saito 50's collection is a little excessive. Three 50's and two 56's, both 56's are silver, the one on the RCM 40 is all original.
A side note, I had an Iron Bay regulator on the 50 I ran yesterday, when I went to remove the engine from the PSP, I pulled the pressure release plug and residual exhaust oil shot up to the ceiling indicating a good tight system.
The Iron Bay regulator held tank pressure all night.

Dave, nice Pile-O-Engines.
Curious about the regulator as I have never tried one.
Does the regulator hold pressure when the engine is at idle? For how long?
Do you have to lean the lsn when using a regulator?
Is the transition off idle better using a regulator?

If you set the engine up with the tank in a good position there will be no change when the regulator is installed other than you can run the engine right at peak because there is no mixture change from full to empty. Some complain that you can't get the engine much richer than about 250 rpm rich of peak. It is a demand regulator and won't supply much beyond the demand. Which is just fine since there is no longer a need for it. It will idle longer than you need, I've never tried to see if it would run out of pressure. Acceleration is of course clean and crisp without the rich top end. Lube is adequate at peak.
John at Iron Bay was not sure the regulator would feed a Saito 2.20, I cleared that up for him.

the only thing I can say that I don't like about the Cline and Iron Bay Reg's is their size, if some one were to put one on the market half the size for half the price there would be many more sold. but with that said the size would not stop me from buying an Iron Bay .

I decided to pull the cloth off my Chipmunk and recover it with plastic, and that came in today. The colors are very close to the rustoleum I used, so the cowl will match, but I need a whiter white since the Rustoleum turned yellow. If the FA100 will mount to the same holes as the Magnum 91, I may swap engines, but if they don't I will keep the Magnum on it.
Nice job acdii.
Yes, the mounting hole centers of an os/magnum 91fs are close enough to an fa100 to work. I just swapped out my fa100 with an os91 on my 4*60, selling the plane that way. The prop hub is further out from the mounting holes on the fa100 than the os91 though.

Its my machining bench, balsa dust on it would be bad. Besides, I got a new control board and filters for my shop air cleaner to combat the dust. Worked great when I routed the drawer and door faces. My balsa benches are on the other side of the shop too, don't want dust in the laser.
New APC are all balanced. The worst was the 15x8, it took 30-40 strokes with 220 grit emery cloth to blade balance. The rest were in perfect blade balance after dulling the TE. Hub balance was perfect on all 6.
The factory 125 muffler tailpiece arrived a couple of days ago, thanks Gary!
All set for the 115/125 shootout, waiting on weather.

If weather holds out like they forecast I think I will see if I can get the YS63 running in the Liberty Sport. I just now realized I never put a needle extension on that one. I looked everywhere to find instructions on setting up the regulator and came up empty, so hoping it works now that it is clean.

there as confused as I that you are run such engine in your liberty sport
Don't be looking for test runs for a while, lots of rain here for the next 7 days. High humidity is not conducive to testing IC engines turning props. It's a double whamy, moisture displaces fuel in the intake charge and props are harder to turn in moist air. I'll wait for conditions to improve.

Power to weight ratio. It is the lightest engine I have with the power to fly it. I was going to put the Gemini II 120 on it, but would have needed 7 ounces of dead weight in the tail, then considered the FA100, but would have still needed dead weight in the tail. The next engine I have without dead weight in the tail is the YS63, so thats what is on it.
