That’s a bigger motor, should work with a larger design swinging a 9 or 10” prop. The ESC might be the weak link with a big prop, the Explorer would work with that motor, you could make a parallel connector for 3 of the small packs to power it. You could also skip the motor and make a simple soarer, use the ESC as a Bec or add a separate Bec and then the small batteries can power the RX. You could make a power nose and folding prop for the Soarer too, that would work with the small battery since the motor would just be used occasionally.
