I just bought a used Duratrax Maximum ST off of eBay for $100USD (price seemed right and the seller had a good rating) and the .12 Torq engine is currently tuned for an altitude of 215 feet, at 95 degrees, with 100% humidity. I live at an altitude of 3,000 feet at 75 degrees with approximately 20 to 40% humidity. Being a noob I am not 100% sure how to tune my engine for my environment. I suspect that since the air is thinner at my altitude that I will be running richer than when it was at 212 feet. If this is the case I'll need to turn down the high and low speed needle about 1/8 to 1/4 of a turn then test run and measure the temperature?

I have 20% Nitro with 12% lubrication and a O.S. # 8 glow plug.

Any advice to a new member is greatly appreciated.


Thanks,
Matt

Less air pressure/higher altitude = leaner setting
The colder, the richer.
the less humid, the richer.

the whole thing is about tuning and at the bottom is a chart.

Thanks STPWNNR. This is a great page for tuning tips.
