OK, I have the Wagstaff 300 and am now considering a gas engine (BME 50).

I have absolutely no experience with gassers and have some questions:

1. Do I need any special starting equipment?
2. What gasoline do I use (literally, BP, Shell, am I nuts, etc?)
3. Do I need a special gas tank?
4. Does the gas engine need a "glo" warmer per se?

Thanks for responses and sorry for the really basic questions. I am trying to decide what type of engine would be best for me (and the plane), i.e. two stroke, four stroke or gas.
