There should be a datum line on the plans, that's what should be level. If none is given, I'd keep the horizontal stab/elevator level if the stab is flat. If airfoiled, the leading & trailing edge of the stab should be level. With most aircraft, the wing will then be at a positive incidence. Slightly nose-heavy is desired for the first few flights. <div>
</div><div>We were at the field when a member showed up with a new 1/4 Aeroworks Extra. He asked the club hotshoe to do the first flight. Mr. Hotshoe does a preflight, finds a couple linkages need adjusting, then turns on the transmitter and finds a low battery. The owner hadn't charged th enough, so we put it on a field charger. We asked about the CG, owner wasn't sure it was checked. I pulled up the manual on my phone, found the CG and we measured and marked it with tape and a marker. With a guy on each wingtip, we picked it up and found it was very close, just a bit tail heavy. Plane was level when lifted 1/4" behind the marks. Finished charging, took off and it flew near-perfect. </div><div>With 2 people, you can check it easily. </div>
