Today a modelling mate gave me an engine from his RC helicopter - despite numerous attempts, he couldn't get the engine to "run right" so it's now mine to keep & play with Should be fun, I enjoy a challenge.

For those wondering, my friend replaced this engine with a new OS Max 37SZ-H ringed engine.

Anyway, I'm curious as to what brand of engine it is & any other info that is relevant - refer pics below. No names, letters or numbers are cast into the crankcase, although on the transfer port side, there is a nameplate (sticker?) that has on it "37" and what appears to be the initials "ST"? The carb has the number "2" cast on the side that faces the engine. Oh yes, and very attractive blue anodising on the alum heatsink head.

Thank you for your assistance [8D]

Looks like a engine by a taiwanese company, Super Flying Model. They used to sell engines under their brand name for a while. I don't think they manufactured them. That engine looks familiar.

Except for the logo sticky thing, the engine is identical to a pair of LEO engines that I had a few years ago. Must use castor oil with these engines or "they run funny".

It's a LEO 37

You used to be able to get parts from www.justengines.unseen.org

Here's a MECOA 32 Heli but they do not sell a 37. It is made by LEO of Taiwan

Thank you to all who responded. Knowing what you've got on the workbench & the background behind it only adds to the pleasure [8D]
