I'm sure they are fine engines, depending on the application. The rear induction engines could be interesting ... for a speed plane anyway.  :)

I ran the ST G.15 in A speed in the middle '60's. Nice engines, quite fast (if setup right) for the day. The K&B is the same model ('67, I think, wedge head from casting) I pitted in Rat. It'd go 134 with a trimmed 9-8 Tornado nylon and 40%, otherwise stock. It started so good that we didn't need to practise much. My pilot flew Navy Carrier, and could put the plane down in the right place. I ran the ST .29rv in B and B Proto, but it was a lapped, flat topped piston, while that .40 you have should be a baffled piston, probably ringed. I'd expect the ST would be on par with the K&B, but last longer. We had to replace the piston/ring/rod/cylinder every winter on the K&B.
There is a move afoot for a Vintage FAI FF class...'60's F1C's would be great fun...for that G.15...if you have a place to fly them. D>K Steve

I also ran the Tigre 15 and 29 in CL Speed in the sixties. I still have my Speedmaster handle, magnesium pans, and the spinner from my last ST 15.  :##

That G-21 40 is a first generation RC Pylon engine, similar to the engine I ran for a season in my first Lil Toni. Great museum piece.

Take care,

Ron

They are also good for some good money on the bay. The ST 15 will bring the most, then The ST 40 and last would be the K&B 40.

Actually they're pretty useless, just pack them up and send them to me, I'll be sure to take good car of them!!!!!!!!! LL~

Really, they were the best of the best when new.  Progress has made them collector's items, put them on the bay you will probably get a surprise what they will go for.

Hi

I see a tremendous amount  of rust and corrosion on these motors,  You may want to peek inside and check them out for rusred parts and bearing.
The last one K&B..looks like one I got in here that had been cleaned with Dawn Power Dissovle.  I was clean on the outside but had massive corrosion and rust on the inside and all other parts that were covered


Regards
Randy

The only rust that I can see is on the needles of the ST 15 and the Torpedo, all the internal parts are RUST FREE and in PERFECT working order. The Torpedo has a little patina on the outside of the crankcase but everything else is pristine. Randy did you get my message about the 60? What do you think?


Thanks, John
