JOHNSON 700 SERIES 683 MOTOR. IDEAL FOR R/C BOATS. VERY POWERFUL 100 WATT, 3 POLE MOTOR WITH BUILT IN COOLING FAN. This is a very high quality, high power motor with built in fan. We have test run these at high speed for 30 minutes at 12 volts and they stay cool and smooth.
My review of this product will be limited. I have purchased this motor with the view you for another project I have in miind personally, what I can say about this motor is that it is sturdily built and I know from past experience with motors this motor will be a very very powerful motor, and the high speed ratio to revs per minute is more than sufficient for any RC model water speed craft, and if your adventurous even model gliders. The internal fan built within the motor should give a model a clue as to the power of this motor. The seller of this motor knows his stuff.. sorry that I cannot include any photos as I am in the mist of moving abode and 92 miles away from where I am.
