K&B 35 Stallion

[Bill Johnson]

I picked up a K&B 35 Stallion recently. The engine is virtually brand new. It has never been run and has the original K&B plug.

I understand this was a low cost alternative to the Green Heads. Is it worth running in a stunt plane? What plane would be suited to it?

[Dave_Trible]

Bill I don't think I'd invest (any more) new full stunt airplanes on it.  I latched onto 4-5 new ones pretty cheap on the bay. My thought was to put one in the Sterling Spitfire I built,  like one my cousin had in the 60s. The other I figured to put on trainers for grandkids.  Pretty well cooked two trying to get through the pattern on the heavy-ish Spit.  Finally put a McCoy Redhead in.  Better.  Use the Stallion on a light profile sport plane.  I have heard folklore about a few having good luck with it.  Mine will stay on the shelf.

The K&B Stallion 35 was my first "big" engine back in the 1960s when I got tired of flying half-A. Break it in carefully on a mild, oily fuel and run it on same and it should last quite a while for you. Mine had many flights on several models until I ran out of mild fuel and filled the tank with Supersonic 1000. Boy, did it run fast! But when it came down it was completely worn out. Lesson learned... It was built to a price...

The Stallion is like the McCoy motors and need a real break in. I had several and they ran fine for stunt. I thought they were better built than the Fox 35 and more powerful.

I have PowerMaster GMA 10/22 that's boosted up to 25% oil by adding castor, but do you think the 10% nitro is too much? I think that's still pretty mild compared to SS 1000 which, if I understand correctly, was 25% nitro.

Stallions were LOUD.  Only two screws hold head &a cylinder to the case. Not recommended to use a"clamp-on" muffler. Good sport motor .. cheap....probably "disposable" rather then repairable.  A good newbie entry motor.

I ran clamp on mufflers on them. The clamp is on the case not the bolt on sleeve. I would guess the bolt on sleeve is the weak part but I never had any problems. I ran one in a sport scale model for a long time. I gave them away to flyers who needed motors. There were several variations of the motor. Mine were the chrome case version.

I was going to say that the only ones I saw were shiny cases, not matte like the OP's picture. I would guess they were tumble polished with some good abrasive & media, but definitely not "chromed". Hand polished, maybe.  Steve

I flew the S&*% out of a CG P-40 with a worn out Stallion. I liked it but then I was doing more than banging it around the sky. I have a new one I thought I'd try but haven't been there yet.
