enya 25 r/c engine any info
 

I recently found an old plane at a swap meet. bought the plane on site and found a enya 25 mounted to it. The plane, I found to be rated for a 40 but this little 25 is actually plenty if not too much for it. I looked for some backround on it but I can only find info on 29's and such. What's the deal with this little motor? I generally fly 40 sized sport planes and have never seen this kind of performance from such a small package. If anyone has any info I would appreciate it. Info on other enya engines would be great too.
