who says 5S for 30/1?!
My two 30/1 have now a long live with 4S 3800er and MIniFan or HetFan @100-120A and 52000rpm and >1500W
But if you dont cool the motor, you get easy a problem. We have damaged/ exploded a 30/1 rotor in a f5b hotliner @4S 170A because of bad cooling and high rpm. The balance weight will also get away....The rpms are a problem if it really turns 75k rpms.....
Who wants to test it?!
my Lubach F16 is really hot with 1500W and 1190g with the FULLYMAX 3800 35C cells......
