ROAR:

8.5.4.3.4 ROAR Spec 21.5 motor: Only three slot “Y” wound stators are permitted. No delta
wound or slot less stators are allowed. Only circular (round) pure copper magnet wire
permitted. The three slotted stator must be wound with 21.5 turns of two strands of a
maximum diameter of 21AWG or 0.0724mm per slot. The resistance for each slot of
the stator shall be tested and a minimum resistance figure will be determined upon
submittal.

Isn't it 21AWG = 0.724mm? Is it a typo, there is one extra ZERO on the 21.5 rule...please clarify.
