What engine is this

[Will Davis]

This engine was Bought by a Control Line Scale flyer at a World Championships around 1990 . It appears to be a 50 to 60 size , baffle piston . Good quality, Run some on the bench , but plan to put in a ARF  due to the rear exhaust , it is a little different than most of my models

No idea what it is, but the number on the case probably indicates the displacement.

10cc = .60ci

Russian or Ukraine, most certainly. Nice work. They have  to make their own screws, 'cause they can't go buy that stuff, so slot heads are it. At Golden State (Clovis), I heard that Sergy Belko had bought boxes and boxes of socket head screws to take home, and he did have an engine and other items for sale. In fact, this engine might possibly be a Belko. His stuff was beautiful, and worked very well. The fella can fly really well, too. I think he left a couple days after the contest.  Steve

    It appears to be of good quality throughout . I have run it more on the bench, starts and sounds like a good stunt motor , maybe a little over compressed , I will try to fit it into a plane and see how it goes . It has a real nice bolt on rear exhaust muffler , no coupling , with a support mount on the rearof muffler  .

 I like the needle valve Assy  too, has a retainer cast into the case to stop the NVA from rotation , nice touch

It's logical that it would seem over-compressed. Remember - a vast % of European engines are designed to run w/o Nitro, and therefore a higher compression ratio is necessary . . .

I have one of Belko's motors, and this one does look a bit similar.
The casting and finish lood very similar. And, as Ralph said if this
is in fact a Russian or Ukranian (most likely) motor, then they are
designed to run with very little or no nitro at all.

I have one of these as well. One of the Russian team members told me at the worlds at Muncie that it was a copy of the Discovery Retro.

 It's not Sergey Belko's work. My guess is Strakhov (RU) or Listopad (UA)
 Any text on the other side of case? L

 From the LAN-logo I'm pretty sure that it's an engine by Alexander Listopad. Not Russian but Ukrainian. It's not exactly a copy of Retro, allmost all East-European stunt engines use similar design principles. Also note that shaft has plain bushing. Propably a well-running with not too much power engine for a lightweight model. When running it, it's better to start with 80/20 all castor mix and a lightweight wooden 10..13"-6 prop. Only after that it's worth experimenting with synthetic oils, nitro and so on. L

Thanks ,

Great to know the origin , I plan to use Castor , since the plain bearing , with a good break in .
