Has anyone attempted this yet? If so; is it possible to bore out to a .60 displacement?

Just curious

HUMMMMM, now that's a interesting question, unfortunately I'm not sure your going to get a real definitive answer. This might be the time to step back and just say no!!!!!

It could very well be that the bore is the same,

the OS50SXH bore is 22mm, the OS site does not show the bore for the 60SXH but the 60FX (aero) is also 22mm.

Also, boring out the sleeve would require replating, while translanting the 60 sleeve would probably not work because of the difference in height of the exhaust port.

I see in your profile that you are using T600's, is it for them? You know you can fit a 60 or even a 90 in that heli directly..

Yes, using the N600 however I was curious to see if anyone has done it. I know it's becoming a common thing on motorcycles and other high end engines and so forth, but not sure if it's going to have the same outcome.

I understand the fact to re-plate and re-sleeve the engine; it would be a nice to have little modification if it was easy.
