You could still use the motor . . I would. Just run a band-saw through the middle of the motor box and shorten it the desired length using balsa traingle stock in the four corners.
The Hyperion motor is dimentionally exactly the same as the Hacker. Bolts straight on. As a matter of a fact, the specs for the motor are very close just 100kV more which is perfect for the 5S pack. Would almost bet that this series of Hacker and Hyperion outrunners are made in the same factory. They sure look close.
I might have tried that motor if it weren't for me running 6S, the kV is too high for 6S. I thought about using the Axi 4130/16 (the other motor they list as a drop-in) but I've had bad luck burning them up the past year. If I can't find a hacker A50 16S by tomorrow afternoon I might do what you suggest and simply modify the motor box.
Would you cut it in the middle, take out some and join it back together or knock out the firewall, shorten the box and try and re-key it in?
Thanks for the suggestions...
