it was close, but I would say the x440 is a bit faster(did not have gps on that thought)

What prop next? It looks like you may be able to use a X642 or that prather temps and amps permitting.

I guess that prather 220 is less pitch and only slightly larger then x642, so I will try that next.(needs a bit work, that steel is hard to work with compared to berilliym)

Honestly, only the motor was warm after 6minutes of wot on x440! (1,2,4 and 6 min runs, did not try 6mins at first)

the k45 is another option to test
