great madien flight, or was it?!?

Finally after 2 months I get my new bird in the air. After a few corrections and trims, it seemded to behave like it should. But, then something happened, something I did not expect. Afer a few moments of hover, it began asending and desending in the air. I turns down the throttle and it would stop, I increase the throttle and it won't stay steady. I also noticed that the main blade screw will not stay tight and become loose during flight. I know I can't loctite them or put some kind of of sealant on the screws, anybody have any ideas.

You have to put loctite on the spindle screws.

You need to go over all the screws in the head again - make sure none of them is open!
Is that the screw which goas through the blade? there is no way it can come loose of the nut is the correct one unless it's defective - then you need to change it.
