Luis, Luis,

What motor, pinion, and how much pitch?

Is everything free to spin?

Is there an extra twist in the tail belt!

Answer all so I can help you.

ESC/BEC
Sounds like the heat build up in the controller has/is weakened the ESC..
On an inexpensive unit, you might have done better to pick a higher amp rated one.. it is allowing a voltage drop that is causing the dreaded "brown out" in your Spektrum rx's..
Lot of draw on the systems with digital servos, and worse if it had a fbl unit!!
Pretty sure if you invest in a better ESC, or add a separate bec, like the Castle Creations 10 amp.. your problem will go away..
But, your set up also needs to be correct for all of this to work properly too, as asked prior to my post..
Good luck and remember to have fun!#

ESC
I would suggest the Castle Creations
Talon 35
All around good ESC with a strong bec built in.. and priced a little above similar units..
Yes, I am on the team for CC, but I will only recommend products that I believe in..
