ok, i just got a trade for a unfinished CA extra 27%. covering are only applied on one side of the fuse, so i have to do much more. this is MY FIRST gasser. i really need help setting a gas engine up. i've seen guys at my field got problem w/ gas engine because of interferences, how do i avoid those? i'm planning to use a Brison 3.2 engine, would a 20 oz tank be enough? how long of a flight would i get? is there any difference from setting up the fuel tank from glow to gas? how about the engine mount? for this plane all i see it a plywood box that protrude out of the airplane... what do i need to BEEF this up making it strong enought? and i heard guys on RCU that they GLASS the engine mount.. if i do it, where would i glass?

ANY pictures will help... thanks a lot

I would suggest , first , to do a search on "RF" and "Brison", your question has been answered on RCU many times and the info is readily available.
