1 kW motor : rear G360, GMAC, 9C RH212, Crystalyte H3540 - or front Grin All Axle ?

[goatman]

i have the hs3540 with the phaserunner, dont like the axle but grin sells the 3540 w/thru axle and good torque arm. im switching to the 212

at 17s/61v and 3200 watts, had to heatsink the phaserunner. if i was at 52v the PR would be in constant thermal rollback on hills

Thank you !
Have you built the heatsink yourself ? Do you have a picture ?
