Ok, so after a bit of work, it was the esc. Replaced it and then had to do some additional balance work do to reinforcing of the tail feathers. Was able to get a few flights in today. As ou can hear in my video the motors are working perfectly. Thanks for the heads up.... I am currently thinking of trying the throttle mix as you stated in my dx8. It looks good to me, just curious why you went with 60% on the mixes?
Anyway here is fpv of my twins over Dayton, ohio
