|
Same diameter as SPEED 400, 28mm, 29mm long, weight is 1.76 oz. 1/8" (3.2mm) diameter shaft. Can be used in place of SPEED 400's with much greater efficiency (longer running time on the same battery) and much more power. Use Jeti Brushless Controllers of 18 to 40 amp capacity. These work well with PMKG gearboxes. (Use M3 mounting screws.) |
