A) How do you stop the engine running?
You normally set the radio so when you move the throttle stick and trim to the bottom the engine stalls (carb closed)

B) How do you prime a engine
I'm a bit naughty here, i use an electric starter, and pretty much wind it till it runs [:-], best way is without starting equipment connected to the engine (glo start, starter motor etc.) put your thumb over the carb, get a good grip on the prop and turn the engine over by hand till fuel reached the carb this kind of thing you will be taught at a club (i hope you planning to join, or have joined one?)

C) Do you glue the wings together with epoxy or do you attack them together a different way?
The way it's normally done if by fitting a dihedral brace (will be a bit of thick ply with an angle in it) with lots of epoxy, and nice coat on the 2 meeting ribs, then simply pushed together. It's also best when you've just put them together to lay them out of a board (or kitchen floor if it's flat...) with one wing propped up to give the correct dihedral


Hope that helps
