Default Align 700mx

Align 700 MX
7 turns in 13 ga. Parallel LRK wye's 835Kv and should peak well over 10kw. LRK winds or single layer fractional slot concentrated winds have shown in lab and real world to work better with sensor less drives. less torque ripple better efficiency, more torque, higher amperage ratings are just a few of the benefits that come with rewinding in this style.

Here is some Spudz FE Boat cal plots on the Tuned Align Single Layer parallel wye 700 mx. The prop wizard found an ABC 1918 the most efficient for 10s 9800 mah hydro in performance trim. Alot more in this motor....

Motor constants
Rm .oo5 ohms
Kv 824
Io 3.27 amps @ 22.5 volts
Weight 448.8 grams

28,221 rpm
141 amps
4.995 kilowatts Pin
4.728 kilowatts Pout
Run time 4.15 minutes
Est. Speed 79.42 mph

ABC 1818 calculated as most efficient prop for performance hydro @ 12s lipo 9800 mah with this motor

33,940 rpm
153 amps
Pin 6.394 kilowatts
Pout 6.125 kilowatts
Run time 3.85 minutes
Est speed 90.12 mph or 145.03408 km/h
Eff. 95.80 %

The efficiency doesn't drop of till apprx. 268 amps. So it would be apprx. 12kw and over 2 ft/pounds or torque @ that point.
