203 forum posts 19 photos | Some years ago I completed a 1 meter long tugboat, originally built by my son 25 years ago. Searching for a motor I found information on the internet to use a 12V brushed motor from a car interior blower. Cheap and with sufficient power to give the boat the speed belonging to its scale.

Edited By Bob Mc on 23/08/2021 08:09:09 Hi Bob. The term '400 type motor' ( called Speed 400 back then..) dates back a while, and very loosely referred to a motor around near 38mm long, a 500 motor was near 55 or 56mm long, etc. The old 400 DC motors were around 100watts max or so, 10 to 12 amps typically. If I recall, the Speed 400 was around 30mm in diameter. Are you set on a DC motor? Do you already have the DC PWM RC speed controller? If so that would set some limits on the motor amps/volts choice I guess. If you are not set on DC, the RC brushless DC motors are a good option. Much more efficient and more power in smaller packages compared to the somewhat dated construction of the cheap Speed series DC motors. A visit to your local RC hobby shop will deliver.. Eg:
