Pitch with a KK2 board

[SimonHenn]

Hi guys, 

I`m building a quadcopter with a KK2 controller board. However, I use the tilting of the rotors to yaw the drone and that works fine. Then, I wanted to replace the functionality of traditional pitching with rotating all rotors either to the front or the back to move forward or backward. Unfortunately, that didn`t quite work as imagined and I`m not quite sure why. Could it be that when the board receives a signal on the pitch channel it expects the craft not to accelerate forward or backward but to move around the pitch axis and when the sensors don`t detect such a movement (because pitch is replaced by tilting rotors) the board somehow tries to correct it and the craft gets out of control ? 

If so, has any of you guys an idea how I could solve this problem ? 
I thought maybe I could use the aux channel as an additional channel to implement the forward/backward movement through tilting the rotors. Is that possible ? 

Thanks for your help!

I hope someone can answer your question. But this FC goes way back. I know some of the members here were not even born when this was around.

Which one would you recommend ?

It depends on what you to do? I am not sure of your objectives.

Just build a fixed frame quadcopter to fly fpv like what you see on YouTube?

Do you want a tilt frame quadcopter?

What purpose is this quad for?

The goal is to build a VTOL airplane. That`s why I don`t want to pitch to move forward but tilt the rotors. Yaw is realized through tilting rotors as well, roll works just like with a quadcopter.

It looks like you do have the correct FC. I assume you loaded the VTOL custom firmware. I probably recommend you ask your questions at the link below. Most members here are not familiar with this type of setup.
