1512 2.5D vs 3D on 5S?

[rootar]

stum the 3d drawing as many or more amps on 18.5v compared to the 2.5d would only be true if you had extremely high gearing that REALLY REALLY loaded the motor, but only 40mph isnt anything for either of these, so the 3d will definetly draw les amps than the 2.5d on the same voltage. its only marketed as a 70amp motor while the 2.5d is a 78, this is at max voltage but you must take into account when running on the same voltage the 3d Will be more efficent on 5s and up, now getting down down below 5s i dunno how they react as much to the slower rpm because that would be a
large gear up to run the 3d at 40mph on 4s
