Bundy is the preferred drink, but we get some good firewater (sugar cane sourced, not molasses rum amongst other things) and the other 1/2 is she who is most tolerant.
On engine blow ups I was reminded by an old ex Ansett mentor of mine about 2 beauts one was a JT8D in a DC9 that tporched on start up but we continued because it would blow out, well it did when engine hit the ground cause the rear mount bolts broke, and the Alison 501 in the L188 Electra that first sheared te reduction gear box and the prop fell into Sydney Harbour (well the entrance) and the engine saged on landing cause the upper 3 mounts broke around the retaining bolts.  This was on a retur flight from Lockheed where we had some mod work done but my best was sticking my head inside the combustion section of aRR Dart (hole in side of chamber ) and telling the pilot I could see nothing wrong inside the engine and him then trying to start it

Thanks Mike, the wind today is straight out of the north and my wood pile is dwindling fast.
I drove up to Virginia Beach Monday, felt that cold air myself. The air is dry compared to here, so it didn't feel as bad as I thought it would. Watching tankers pulling was a novelty. I got a kick out of a guy in a wet suit trying to surf in that water on purpose. I rushed home by Wednesday.
It should hit 72 today, planes already in the truck, while coffee brews. I'm guessing the field will be less crowded than usual. Everything is closed, may as well fly all day.

My Mother in Law lives in DeBary and said it was 28 the other night, unusual. No new Saito came so I'll just have to play with the old ones. Spaceworm wants to meet up and fly the first fit day.

I got a Saito-100GK right out of the blue... I must have said something a while ago and it stuck...

I wonder - has anyone put one of these into a Top Flight Mustang (Gold Edition kit)? Did you have to do anything special to make it fit?

Love that engine!

I got a early Christmas present just after Thanksgiving. It was a TF Gold Edition AT-6 ARF with a Saito 100. No problems fitting it in, but, of course the T-6 has a round cowl. However, I mounted the 100 inverted (with digital on-board glow), so it may not be that different than the Mustang? I will be fitting a TurboHeader muffler to it also

I plan to fly it first fit day with Hobbsy

Merry Christmas and Happy New Year to All.

Sincerely, Richard

HELPPPPPP
I bought an used Funtana S, complete except for the receiver.
I bought a JR receiver for it. The airplane has two servos for elevators. I bought a Y connector and plugged to the elevator slot in the receiver.
After binding, SURPRISE...... one elevator goes up and the other goes down.[X(]
I tried the reverse option and..... you guessed, one goes down and the other goes up, what do I do now?????

Get rid of the Y and plug each servo into the receiver. With individual channels reversing the servo will work. I you run out of receiver channels use a Matchbox or something similar or reverse a servo.

What JNorton suggest will work but for a simpler method is:

Unscrew and move the servo arm on one of the servos 180 degrees so that the pushrod is on the other side of the servo.

If you need it to stay on the same side of the servo for direct line of the pushrod to the control horn thenturn around the servoarmand also remove the servo and turn it around as well.

I need a little advice...

I have an FA-50 that has a very leaky intake valve so I took it apart and took a look.

The valve itself was quite worn on its face, but to my inexperienced eye, the seat still looked good. The fit of the valve in the guide seemed OK too. In addition to the wear on the valve face, there was also a considerable amount of deposits on it (yes, even right where the valve contacts the seat). I gently scraped the valve face clean and put it back together. Compression was improved, but was not nearly up to snuff (which I didn't expect, with that much wear and pitting on the valve face). BTW, I do understand that because the valve seats are chrome plating on aluminum you cannot lap the valves in on these engines.

I'd like to hear from some folks with experience as to whether a new valve would likely seat in, or if I'd more than likely just be throwing good money after bad. These are not expensive engines, but new valves would run me close to $20 shipped.

Also, any ideas as to what would cause such substantial valve face wear? I know little of this engine's history as I bought it second hand.

Thanks!

Try lapping with a little tooth paste.

Usually the valve is warped or the guide is bent. A new cylinder has a pretty good cost.

Silv, make sure there is plenty of clearance at the rocker arm, many here advocate setting the valve lash tighter than Saito recommends. Its possible for this tight setting to cause the valve to sit too lightly on the seat and leak. Saito recommends .004"

If you need it to stay on the same side of the servo for direct line of the pushrod to the control horn then turn around the servo arm and also remove the servo and turn it around as well.
Unless your geometery is the same, doing this will result in unequal throws. Do a CAD drawing and prove it to yourself. Hitec and a Futaba servos rotate in opposite directions.

Geez - How about just spending $20 on a simple reversing Y-harness from Maxx products instead? They're cheap and reliable and simple. Plug-n-play. I've got hundreds of flights on them without a single glitch.

Finally! A good frontal shot of Hobbsy. I agree with you, Dave. Your family has a proper respect for you, as they should. Now you are beginning to look your age. In another ten years, you'll look forty. Spirit years, that is...

Thanks Ed and Jim, I may be starting to look my age nut I refuse to act it. In a real age test I took last year I'm 54, I hope that trend continues. It's the Saitos and my Harley, that keep me young. I'd better say my wife too. She's 67 and doesn't have a single gray hair yet. Her mother was 75 before she got gray hair, she's 89 now.

Well, whatever you're doing, keep doing it, Hobbsy. You might appreciate this... my buddy has a great T-Shirt that says "If I ever knew that I was going to live this long, I would have taken better care of myself"

Now for a question... Hobbsy, W8YE or BLW will probably be the first to jump on this, but maybe not...

What is the difference between the Saito FA-125 and the Saito FA-125a ????

I got a very nice Saito 100 for Christmas but that project went South, so I may send (with my wife's permission) the 100 back and get the 125a. Can anyone remember the difference between the 125 and 125a??

Happy New Year everyone. Be the first to fly at your home field on January 1. That will tick everyone else in the Club off!!

When it came out it was called the 125a.

They are into later models now? I know the cylinder on the new ones look like the cylinders on the FG-20 gas engines.

I have three 125a's and two FG-20's

However, even though they are into at least the "B" production sequence, in the ads, they still call it the 125a

Last year tihis time I worked on a 125a that had the latter style cylinder on it. It really ran good.

You will like the 125. They have the same foot print as a 100.

I have a 125 on a Twist 60 and it is an absolute blast. I also have a 125 on a You Can Do 60. They are my favorites.

It's a nice engine, for sure. There is supposed to be a little more power in the 125a with the new style cylinder.

That is the only 125 that I have. It is on a pattern plane that is somewhere around a 90 size. It pulls it ballistic any time I want.
