Can anyone help me ID this Engine ? I am new to this glow and got this cheap dont know if it even works or not dont have it yet. But if anyone could help ID it I would like to get everything I need to mount and run it.

It looks like an OS Max, Max-H or Max-HP. 1965-1970. Does it have "Max-H", "OS" and a number on the side of the crankcase?

I do not know if it has any markings yet I just bought it today off of ebay for $13 wanted to use it to get in to GLOW and learn about the engines and do it cheaply. I will find out some time next week when I get it if there is any print on it.

$13 ? Sweet! Let us know what markings it has when you get it... (What did the ad say?) Also post more pics if possible when you rec'v the engine-

The add said "THE MOTOR HAS COMPRESSION. COMES WITH GAS TANK AND MUFFLER. AND THREE WHELLS. NOT SURE OF THE NAME, ON THE SIDE IT HAS MAX OS AND A 15 IN A CIRCLE. IT HAS SOME KIND OF MOUNT. THATS ALL I KNOW SOLD AS IS, DO TO MY LACK OF KNOWLEDGE".

the item number is 3187254876

I believe we have identified your engine.

1975 OS Max 15 R/C.

Nice engines.

I agree that is most likely the engine I appreciate the assistance guys. Here is a [link=http://www.osengines.com/history/ostimeline05.html]link[/link] of OS engines 1969-1975. Now I just need to research and learn how to run, maintain, and fly it.

nice engine. i once had the thunder-tiger clone and while it wasn't really big on power it sure was easy to run.

this engine has a plain bearing and lapped iron piston/sleeve so you should use at least 20% oil, preferably all castor, if you want it to last. and last it will if treated right.
not knowing the history of the engine i would give it a proper break-in. short, very rich runs with complete cooling in between.
