The only things remaining are to re-check the balance and re-check all the radio set-up. Here's the discussion on balance on my RC GROUPS thread:

I feel like determining balance is my Achilles heel. I very frequently get it wrong on the maiden and the position indicated on the plans is most definitely wrong. I just barely got the model back in one piece with it "balanced" at that point.

I think part of the problem is the different ways that different modelers used the term "balanced." To me, that word means that the model is "level" (for example, with the stab parallel to the ground). Other modelers talk about "balancing nose down." Well, that's not really balanced it is. Can you imagine people using a weight balance like that and saying "balance it with the left side down a little bit?"

Anyway, the number I seem to be coming up with for the CoG is 9cm behind the LE of the upper wing. If I put my fingertips at that point, the stab is about level (I think since I can't really see it properly and hold it at the same time). If I place my fingertips at the 12cm point marked on the plans the model adopts a significant nose-down attitude with the stab also pointing downward.
