Thanks to all of your posts,,,,,it is just what I needed. My tricopter is built and am at the point of connecting the kk2 board. All your questions and answers were spot on. Now I just have to wait on my just ordered usb-asp programmer interface to get here. Then I will flash my board with the Steveis firmware that all talk about which will enable me to follow David's video on setting up the kk2.
In the meanwhile, I thought I would see how far I could get with the stock firmware just for practice. And I came up with a couple of questions. I am using a DX6i and an orange r615x receiver. There is a cable to connect aux ports on both but I have no aux switch on my 6i. Should one connect the aux of the kk2 to the rec. gear port instead? I do have a gear switch on the 6i.(this is my first multirotor and don't know what the kk2 aux port will be used for with the tricopter)
Also, in David's setup he recommends that the two front motors rotate in opposite directions. But he said that they can all run in the same direction. (In my parts order I was unaware at the time for the need of cw and ccw props and just ordered standard props). I would like to work with what I have (at least until the next order). What is recommended by this reader base? Can I get by w/o too much trouble rotating all in one direction? If so,,,,,,how is the rotation direction of the one motor changed? I do not see a "change" option when I am in the motor layout of the stock firmware? Is this possible in the Steveis firmware replacement?
Thanks for all your help in advance!
