no performance w/ 10-blade fan: exhaust too small

the exhaust is too small for a Change Sun fan - either you open up the rear end to at least 58mm so it will at least work decently in flight (for better static thrust choose 60mm), or you install a different fan - of the multibladers, only the Wemo Mini Evo will handle the small 55mm efficiently

Woot! Hey, she got up, flew, and returned to earth in one piece -- that's the definition of a successful maiden!

Now it looks like you just have some issues to work through.

As to the late rotation, I have heard a lot of people blame bottom cheaters, only to eventually find another issue (CG, thrust angle, incidence, elevator throws, etc) so I would check it out thouroughly before hanging my hat on that one.

In any event, you are over the big hurdle!
