Gonna try to hit two birds with one stone on this one.

I've got a CG Chipmunk that I plan to build and am considering putting an OS 91 Surpass II in it. I see that Slimline makes an inverted pitts muffler for this engine (ref. 4012).

What are your thoughts on this combo considering looks, cooling, etc. - the thing costs around 90 bucks.

Also - I'd like to cover the plane with something like solartex so I can paint on the paint scheme.

Your thoughts on this? I'm tired of having iron-on coverings come off after a while. If I went the monokote route, can I spay the whole thing down with a polyurethane varnish to seal in all the stickers and stuff??

Thanks in advance for any input!
