yes, the Graupner Speed 200 ECO runs on 11-19V, nominal is 14.8V. So I decided to try with 5S. I have no experience with these motors, but I hope that if the cooling (by oil) is fine, then it will be ok with 5S.
Looking good. Did you CAD design the foil yourself ?
Hey Chris, did you test things running with 14.8v yet? I’m curious the current draw and results with that motor and ESC?
Mast connection was adapted in order to fit the Slingshot mast:
Looks nice, hope it works out well for you.
Are you water cooling that with rubber tubing or using the large aluminum tube as a heat sink?
That ESC seems really small at only 120A and using 12AWG wiring. It’s going to run hot, be sure to put a breaker between ESC and Batteries to try and protect batteries if things overheat and meltdown.
