Hi, I made a tricopter following David Windestal's design. But instead of using a HobbyKing board like he suggested I used a kk 5.5 blackboard with Tricopter V2.9 XXcontrol KR by Minsoo Kim firmware. I have gotten it to fly, but am still having trouble making it hover and over all control. Would changing to a HobbyKing board make a big difference in performance? I'm trying to decide if I should change boards. Any help would be great.
