It will deff be harder to tune, and won't make nearly as much power.. try to get your hands on the highest nitro content fuel you can. You may even want lower the head a little.

Default Used to live at 9500 feet!

I grew up in a small town in Colorado (Sargents) Never ran rc's back then but ran everything else that burned fuel (dirt bikes, snowmobiles etc) the one thing I fought was engines being too rich due to the lack of air pressure at altitude.The carbs would load up and the engine ran like shit. I would ride my dirt bikes at 11,000 to 12,000 feet all the time, I would actually change out main jets on the trail! I ran the smallest fuel jet available so that it wouldnt flood the engine. There is about 2 psi atmospheric air pressure less at altitude compared to sea level. That's huge when figuring in fuel to air mixtures. I would really keep an eye on temps and lean the fuel down til it performs pretty good and really watch the temps until you figure the sweet spot. It will be considerably less powerful than what you are used to. Have a really good,clean air filter to take advantage of whatever little air you can get,
