Barry, I haven't said much here lately, Last Tuesday my Dr. "cardiologist" said I can't be outside when it's this hot. So, I have one of the new round, "and very cool looking TurboHeaders" for my Saito 1.25, that I can't test, planes I can't fly and a new Harley I can't ride. As Mr. Spock would say, "a colorful metaphor is called for."

Yep those are the guys . Big THANKS to you all , Im going to order a Perry and see how that does. Im running out of options tho.

Think there may had been something a little wacked out on the regulator seemed to be letting a little bit of fuel through after the engine was shut off.

The heat is brutal this week I dunno if Ill be going outside to fly for a while either. I was sweating yesterday just sitting in the shade. Or maybe I was condensating from all the humidity. [X(]

Chris, I have the 125 too and I know you'll love it. It's a smooth engine and a real stump puller. I had an unexpected incident while flying last week. My plane was about 100 feet high when suddenly the engine departed from the firewall and fell to the ground. I think the prop blade broke at the hub due to a pre-existing crack before I took off. The shock from the rotational imbalance was too much for the firewall. My bad, should have checked the prop first. The muffler was pulled out from the cylinder with part of the cylinder. The bearings are still smooth with no unusual sign of freeplay. Compression returned to normal after flushing out some small sand particles from the cylinder and valve chamber. No other damage except for some minor scratches. Good thing the ground was not too hard. I am now considering whether to send the cylinder to Clarence Lee for a plug insert, or to get a new one.

Mike, I broke the intake boss off of my 1.50 a while back, there was not enough meat left to do anything but buy a new cylinder. Yours looks just about in the same condition. I broke mine by having a ham fisted farmboy moment while tightening the intake manifold nut. My bad too.

Hobbs, I think so too. I'll go ahead and get a new cylinder. With the old piston and new cylinder, any advise on the break in procedure?

That was an unlucky hit, Mike. Sorry to see that happen. Yep, the 1.25 is a winner.

There is a guy at the club who has a Hots 60 with a YS that makes the plane scream. He was buzzing it one day with the prop sounding very loud and mean, just having fun with it and suddenly- silence. The engine and firewall separated over a marshy area. He actually landed the Hots without any other damage, but we never found his engine.

Hobbsy,

Sorry to hear about the docs advice. It has been way too hot around here for me. It usually looks like rain in the afternoons once it starts to cool down a little, so my flying time has dwindled a lot. So, you got the Harley in the pic?

I have a friend who runs his engines inside in a spare bedroom. He says that he puts socks over the muffler and learned the hard way to take down any pictures on the wall. I saw a guy start up a plane with the small Evolution gasser in his hobby shop once. It blew about 50 of those model railroad scenery packs off of the pegboard on the wall. Otherwise, it was okay. He used to crank and run a Moki 250cc radial in there too all the time.

blw, I consider myself very lucky not having the prop break on or near the ground. It took three of us to look all over the ground for the engine, muffler, and my precious cline regulator. We found it all! It was also good to find that the avionics were completely OK except for a stripped mini servo for the throttle.

Sorry to hear it, Dave.

Thanks, Ed, Barry and Mike. Mike I just put mine through my usual 40 minute break in, it actually had great compression with the new cylinder as soon as I bolted it together.

Thanks Hobbs, and do take care of yourself.

Have you written out and published your four-stroke break-in procedure before, Dave? If so, can you point me toward it? I have a bunch of new Saito engines that I want to break-in and I don't know of anyone more knowledgable about Saito engines than yourself. I would appreciate receiving your wisdom in this regard.

I bought my 2005 Kawasaki VN800 Classic in August of 2005. Less than six months later I received the same kind of news that you did from my cardiologist, although I was restricted for other reasons before that. It sits in the garage with less than 1,000 miles on it. I probably should sell it, but I'm stubborn.

I have a NIB Saito 3.25 5-cylinder radial, a used 1.70 3-cylinder radial, a 1.25, 1.00, .91, .82 (two) and a .56, all awaiting Christening (break-in). I'm going to run them this Fall when it cools off, if nothing else unforeseen gets in the way. Two of them will end up residing in my Sig Rascals (110 and 40). The R5 will reside in the Giant Aeromaster ARF. I might use the R3 in the Rascal 110 with a custom made cowl that permits the cylinders to protrude.

One of these days I'm going to send Jim an order for a bunch of Turbo Headers.

I wonder if anyone has ever converted an original gasoline fueled Tartan Twin to Diesel? I now have one.

Ed, it goes like this. I use a 16 oz tank and fuel with 18%/syn/castor blend.

10 minutes under 4,000
10 minutes at===5,000
10 minutes at===6,000
10 minutes at===6,500 to 7,000
refill tank and set LS needle with the HS needle at peak, richen top down about 300 rpm and burn second tank at various rpm of your choosing. Do a couple of full throttle power runs during this run. Fly

I converted a Tartan 1.34 single to Diesel operation.

How hard is it to replace a cylinder head on a Saito 100...thanks

Ed,

I'll be waiting for that order!! Have you seen the new design? The 1.50 and 1.80 size is now available.

Take care of yourself Hobbsy.

Hobbsy-

It was late last night when I posted that message about the more active moderators. I've edited it to include none other than yourself, so feel free to give me a swift kick if we meet up in Ohio later this year. I don't know how I could have made such a glaring omission.

Worry not Barry, I just help where I can and don't think about it too much, Thanks

Birman

Can anyone tell me the thread size for the exhaust manifold on a 72? Also, where can I get a tap & die for that thread size?
Birman

RC Specialties

Birman,

The thread is a 12x1mm. I have purchased a bottoming tap from e-taps.com to dress out the cylinder head threads. I am not sure if they have the dies. There may be other sources someone could offer.

Jim

Birman

Thanks for the information Jim. One of the guys in my club wants to make a 90 degree manifold for a special setup.
Birman

RC Specialties

Birman,

There are options available on the market that would probably be cheaper than buying a tap and die. However, I know how those special needs issues are. Good luck.

Jim

Birman

Jim, if you have the time, what are some of the options available?

As a long time Saito engine owner I am stumped at trying to id this engine that came with a plane I bought. It has the overall look of a 100ts but I am not sure. I need some help, can any of you long time Saito Club guys help me with this?

Thanks
