There's a world of difference between interlocking plastic parts that need little modification to fit, and no matter if there's some misalignment or warp, and a wood "kit" that is more a box of sticks and sheet wood that has to have no warp or twist and each piece has to be played with to make fit. The best way to learn flying model building is to start simple and work up from there.

Starting off with that P-61 is like a rookie ball player thinking he'll knock it out of the park the first time at bat. There's the possibility, but a highly unlikely probability. Not trying to be a smart*****, but I and the others here want you to succeed, and have as much fun making balsa dust as we are.

Start off with a box-sided model with an uncomplicated wing, such as an LT-40 (Sig), and then build something like a Cub (fun to fly later anyway) , and then one of the Top Flite kits mentioned above. Get a feel for the techniques, and then walk the rope without a net by building from plans.
