Hello,

I have a World Models Super Chipmunk ARF.

I'm at the point were I need to mount the engine, in this case an OS 90 Surpass. What is the best way? Inverted or 90 degrees? How did you conceal the stock muffler? Did you use the provided mount? While using the provided mount the closest I could get the spinner backplate from the firewall was 135mm. Will this be a problem? The direction call for 125mm.

Finally if anyone has a picture or two I would really appreciate it.

Thanks,

John
