Keep us posted. Im eager to learn how it goes .Just found this thread. Great work KC3FPV.
I'm considering swapping out the motors on my first H and fitting it with a set of Cobra motors. Looking at the specs you have got, I think the 2213/36 700kv model is going to fit in pretty nice. Looking at their data sheet, the specs seem to align pretty well with your findings on the standard H motors, which should mean that I will be replacing the unit with motors which should put no additional load on the power system. If anything, I think they will run a little more efficient. I also plan to use the Master Airscrew 9 X 4.5 multi rotor props with this set up. It will be a little while until I can get this all done, but finding this thread has certainly helped me in trying to work out a replacement motor of similar specs.
Did you ever get any new data, I made some prop adapters too.
Ralphy - did you end up making a 'universal' type prop adapter? The only ones I have seen, so far, will only take a DJI style prop. I have some new Master Airscrew MR props that I would love to try on my H, but they are made for a straight M6 motor shaft.
