I'm so psyched this conversation is happening. I've just not been happy with the plane, figuring it was me, or the neutral wing angle.

Velco, I find the plane does fly better with a little less weight than the 10S 4900mah Rhino setup. I love those packs, but dropping to 4000mah reduced the weight up front by 250g changing to Zippy 4000mah packs (985g is weight of the packs). Not sure though what would happen with the extra weight but CG moved back.
