Which connector size to choose?
 

Im looking to buy a 70mm motor and am wondering if the 4.0 mm bullet connector is going to be able to handle the current or if I should get the largest 5.5mm ones. Thanks for any help.

on my motor, 1512 I use the 5.5mm...IMO I'd go for the 5.5

Thanks. :mdr:

I run 5.5mm on all motors, esc's, and batteries. Except my MMM combos that have 6.5mm on the motor to ESC connection.

Either the 5.5mms or the 6.5mms. I run 5.5mms on my 70 and 80mm motors and they run fine, but I'd go with 6.5s in the future for better MMM compatibility.
