Since I blew out a motor on my Diatone hybrid the other day I decided to swap one of my older 'spare' motors, which was a different kv than the rest - I was expecting the quad to barely even get off the ground, but to my amazement it flew just as well as having all 4 matching kv motors! This is a huge game-changer for me, as I have 4 quads right now that are all down due to one motor being toast on each, so now I can have my fleet up and flying again!

Motors:

3 x FPV Cycle 25mm 1870kv
1 x Mamba Toka 1700kv

The PID controller in Betaflight has capabilities to adapt the way it flies the quad to cater for such differences. Have a watch of the following video. You will be amazed
