My experience-limited ,as yet, with the Pletty:
AXI-noisier, heavier,slightly more fussy re timing on CCHV85HV esc-mine is OK,but some won't behave with the latest firmwareand the brake is noisy with the earlier firmware...
Pletty-quieter,smoother,easier on the CC85HV to program.
Able to use the APC21x14-I think the max on the AXI might be the 20.5X14The pletty is really nice on the 21x14.
Lighterthis can help the downlines without having to use the brake-esp on the 21x14...
