What George said...

Before you cover the wing, make absolutely sure the control system is free and clear with not even the slightest "hitch". If you have any doubt about the strength of the bellcrank mounting it probably needs a tad more epoxy. Double check the bellcrank assembly itself. I actually forgot to tighten the nut once...I hate re-kitting my planes the hard way.
Keep the overall finish light. If you are using dope, silver, yellow and white are the most problematic colors for weight and coverage. The blues are good. Pick up some peel and stick fuel-proof decals to spiffy it up. Put the engine on some kind of stand and run more than a couple of tanks of fuel through it to get used to it's personality. Like kids, those noisy li'l buggers all have 'em.
