V202, JD 385 throttle not giving enough lift

Hi,
I'm running a modded devo 7e together with a JD 385 quadcopter and the 4.0.1 firmware.

The problem is that even when i max out the throttle I do not get enough lift power to rise from the ground.

This worked with the original remote before I harvested the BK2423 transmitter from it.

Any ideas on how to troubleshoot this?

Thanks,
Erik

Do you have the Sticks calibrated?

Is the Channel output going from -100 to +100?

Problem solved.
I had mounted the propellers incorrectly.
