Correct. I have edited my previous post to match your observation.
You are assuming the voltage created in the motor is the same between a 25.5 turn motor and a 3.5 turn motor at the same rpm. This isn't the case. Let's say the 25.5 motor is rated as 1,500kv and the 3.5 is 9,000. This rating also tells you (roughly, not accounting for losses/inefficiencies) the voltage created by the motor when you spin it. At 3,000 rpm, the 25.5 is creating 2 volts. The 3.5 would only be creating 0.33 volts.
