I just finished building the RC Explorer Tricopter 2.5 running a KK2 board. All stick inputs checked good when doing the receiver test, however, the motors won't run and won't respond to throttle inputs. Also, the tail servo does not respond to stick inputs. I setup everything according to this, http://www.pyramidmodels.com/manuals/KKBoard 2.0-short-Manual.pdf. Can anybody help me out? Thanks!
