So all the motors I’m finding require insanely large gear reductions when I plug their Kv values into calculators. I’m looking at this https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6374-192kv-brushless-outrunner-motor.html motor specifically. Theoretical speeds of 100+ mph meaning I’d either have to use a 8:1 gear ratio (a sprocket that large would weigh like 30+ pounds) to have good torque. Would a less powerful motor, like a 1000w be better and give me more torque with a gear reduction in the ~2.35ish range if I only care about hitting a max mph of like 25ish?
