RE: First C/L plane
Oh and forget about setting the CG as the instruction suggest, there hopelessly wrong! I would say between 1-1/2 and 2 inches from the leading edge is best, start at an inch and work it back to suite you style. Remember nose heavy on a control line plane is much less touchy than tail heavy.
EDIT: One last thing, the fuel tank is a piece of poo too, mine was leaky and on the small side, if yours doesn't leak then give it a try.
