What plane is that and info about UCTKAM 2.5KP wanted
Hi all
I got a plane as a freebie!
Can anyone tell me what plane it is?
Also the engine is a UCTKAM 2.5 KP. I do not know how old it is. Unfortunately the main needle is missing.
Where can I get spare parts? I found out that the engine is the same as a MDS-15FR. Is that correct?
Also I noticed that there is no pressure nipple fitted to the pipe.
Can you fly the engine without pressurizing the tank?
Lastly, I have never run an engine with a venturi carburetor.
I am wondering how do you stop the engine in an emergency?
Any help is greatly appreciated. Thanks.

Old Soviet racing engine. Supposedly a copy of the Rossi .15 (there were all sorts of copies back then). I have one sitting in a box, Hobby Club was selling them for about $50 in the early 90s, when stuff started coming out of Russia. Not sure about the tank, I'd use a bladder, myself (like the old F1 racers used to do and like Combat fliers like myself still do).

I don't know if I would use a bladder on it. Usually a piped motor has to run about as rich as possible on the ground and clean up in the air and a bladder is quite sensitive on the needle setting. On Control line speed planes the tank is placed inboard so the centrifugal force makes it richer in the air . This is not possible on an RC plane without a throttle carb. I have a couple of Ucktam piped motors (and an old combat one too) and the venturi is fairly large. I would go suction and run it slobbering rich for a ground setting as a start. If it cuts out, piped pressure is useable, or even backplate pressure with a .015 hole in the pressure fitting. There can be absolutely no leaks. A fairly small prop is good to make sure it gets on the pipe too. Maybe a 7"4" to start. They are a fairly good motor for the time if you are lucky and get a well fitted one.
