Plane is World Models 80" Extra weighing 16.5 pounds. Engine is G62 with C&H Synchrospark ignition. Running 40:1 mix with 87octane fuel and flying at 6000' above sea level. Turning a Menz Ultra 22-10 at 7100RPM +/-

I'm moving up to higher ground and will have to fly at 8500' now.

Could anyone recommend a tuned pipe for this engine? I don't want it to be completely radical and ruin my transition or midrange. I just want something to boost performance and compensate for the altitude at 8500'. I'd be happy if I could just keep from loosing any RPM. I want to continue using this Menz Ultra 22-10 prop as it seems to be the right prop for my plane and type of flying that I do.

I have tried to look for KS pipes, but no luck here using the search function.

Try ZDZ-motor.de
Click on the american flag for english. They will ship anywhere.

KS pipes?" Desert aircraft has them.

For a true 'tuned pipe' for a G-62, Macs makes one - http://www.macspro.com/

A friend of mine ran one of the '1097' pipes on his G-62 ( http://www.macspro.com/tunedpipes.asp ). It did indeed give quite a boost in power.

Current price isn't exacyly cheap.... plus you'd still need a header (which they also make for the G-62) - http://www.macspro.com/headers_side.asp

Anyway, I've seen the system work... and it does. Turned his 1/3rd scale Lanier Laser from an iffy 'sport plane' into a real performer.

Just another option to consider -

Cheers,

save some major bucks and go with the #1197 macs pipe instead of the quiet pipe. i used to run one of these on a zenoah 62 powered "go-ped" and it was still quieter than the original saw muffler.

also check tower as their prices on macs products are normally less than buying direct.
