Hi,
I can't comment on the Knuckle H-quad directly as I dont have one - I built a batbone tri. But I assume it uses the same flite test mounts - in which case I have had no problems mounting the motors other than you will need longer screws that come supplied with the motors - I used M3 x 6mm. I mounted the motors on the bottom of the mounts, the props I ordered went on fine and I didnt have to reverse shaft etc.
I'm a noob too and have since learnt that this motor/prop combo is more suited to fast agile flying rather than weight lifting and camera work but I shot this on my first day of flying so assuming the H quad isnt too much different you should be able to fly no probs - guess it depends what you want
