Integrity is more important than beauty. I've seen works of art show up at the field with perfect covering, only to see the gear rip off on landing, or a flight control come loose in flight...or one of the most popular...the nose gear set screw come loose. Don't worry about perfection. Even a plane that's not perfectly straight will trim out fine at the hands of an experienced instructor. Here's what to worry about...your glue joints are solid as a rock! If the instructions said use epoxy, make sure you don't cut corners with CA. If you put screws into wood (such as servo mounting) it's a very good idea to install the screw, then remove the screw, then run some thin CA in the hole, let it soak in and dry (hardens the wood), and then put the screw in for good. This way your wood won't strip out under the loads of the servo. Make sure your fire wall is fuel proofed, unprotected wood soaks fuel in and doesn't last long! Another thing that provides extra security is a small piece of fuel tube around your control surface clevises so they can't pop oven. Also make sure your wheel collars are tight! A dab of silicon sealer on the axle and threads of the set screw helps keep them there. Give your control surfaces a moderate tug... make sure they stay in! I could go on...but your instructor will give your plane the once over before he takes it up...these are the important things...I've seen a lot of pretty planes hit the dirt and shatter from pilots paying too much attention to looks, and not enough into the airplanes integrity...I've also seen some real ugly clunkers go on and on and on and on...because the owners know what's important!
