  1. Heck yeah 5 Star Review

    Posted by on Jan 20th 2018

    Very impressive stack, super clean, easy to install and very minimal tuning. Flys amazing straight out the box, with minor rate and expo changes needed to suit your flying style. Since I started using this stack my flying and video flow so smoothly. On my 2nd stack now on a second build and about to do a 3rd one. Lots of people are downing these stacks, I and some friends using them have never had any issues. I have literally decapitated my quad and ripped the stack off the quad into 2 pieces, resulting in the pins connecting the sec to flight controller off both boards. I got some wire and solder each section from one board back to the other and it still flys like a champ. So from that experience alone, totally convinced me that this is a high quality stack.

  2. Good All-in-1 stack 4 Star Review

    This a good all in one stack fir tight builds. I have had some trouble with the esc board and needed replacement. Support is good and I would recommend them. The only drawback is the receiver does not support sbus telemetry for the taranis.

  3. Easy to build, compact, and cheap! 5 Star Review

    For the money this is one of the best AIO stacks out there! Great parts in the stack and a compact build at a fair price point
