Hello All,
I have a quick question.
I fly in Las Vegas and it's starting to get HOT! Should I richen or lean out the needle on my carborator? What about the low end ajdustment?
Last time out it would fly good for a while then when it comes time to land or non-aggresive flying it wants to die and I must dead stick the landing.
I have been flying for just over a year.
I'm flyinf an OS 1.20 in an edge 540 that has a few(3-4)Gallons of fuel(Master 15% nitro with 18% oil) through it and I add 1-2 oz. castor to it.
Thanks ahead of time.
Mike
Jester said it well. Anytime there is
less oxygen available, then the fuel mixture needs to be decreased. That is why some fliers think that their newest fuel is better in cold wx, or worse in warm weather, same as going from 1000 ft elevation to a 2000 ft or more. One just has to tune the machine. Like you, once you get above 10-12000 ft. your energy tends to wane. 18000 ft. MSL, is 1/2 atmosphere and it drops quickly as one climbs.
