Does anyone have any experience with the Hangar 9 Mustang 60 scale with a .91 2stroke installed? I'm replacing the installed YS91 4stroke for another project and plan to break-in a new .91 2stroke in my P-51. If anyone has this combination, I would love to hear how it's working for you,... any mods. required?, adjustments to CG?, prop suggestions after the break-in?, I don't expect any suprises but thought I'd ask!

Thanks In advance..

i fly my h9 mustang with a super tigre g90, with a bisson pitts muffler. this weighs about the same as a saito 100. i use an apc 14-6 prop. another good muffler is the slimline large volume pitts muffler. it takes an hour or so of breakin before it settles down and idles its best. these mufflers have large outlet tubes compared to the stock muffler. if you squeeze down these tubes some this gets the back pressure high enough so it tunes well thoughout the throttle range. this setup turns about 10,500-11,000 with the engine set to run a little rich on the ground - you need to let the engine warm up for a minute or so before setting the carb - it will warm up further in the air. all my tigers run grreat . by the way i use 10% omega fuel.
