One thing not mentioned in the newbie thread, and I feel it is important, ALWAYS drain the tank and empty the carb when done flying for any length of time if Ethanol is present in your gas, the ethanol will eat the gaskets and dry out the fuel lines. I made the mistake of having a half tank of fuel in my weed wacker left over for the winter, it sat for about 7 months with that fuel in it and when I went to use it, the gas poured out the tank where the fuel lines are and I found they had disintegrated from the Ethanol. So much for using sta-bil. Gas was still good, no varnish, but no fuel lines either.
Modern carburetors aren't susceptible to ethanol like older models. I use the same gas in my weedeater and chainsaw as in my RC engines and have for years. The only reason I empty out a plane is to keep it from leaking when I put the fuse on the rack inside my trailer.
