Many of the successful tanks ran or used to run upwards of 1500 watt per motor (2 per tank). That should give an idea of the power requirements needed to make heavier tanks turn and move easily.
Brushless will make it into our tanks. I'm looking at a pair of rather large brushless outrunners that could output as much as 2500 to 4k watts if needed. Yet it is not watts that makes the big outrunners a good motor, but the sheer torque they offer.

When my tank are drivaable, wee will se if youre right. I no about the 680 watt -But i have 2 planes with that motor, and in both planes i pull way more than 800 watt, exatly they pull 960 watt-And they dont get overheatet. A freind of mine made a elecktrick bicykle, with that motor, and running almost 20 kmh with no problem-And he weight a bit more than my tank-And i have 2 of these motors :-) Den fredag den 29. marts 2013 19.34.49 UTC+1 skrev Garnet: The motors you are looking at are great for airplanes but for heavy tanks they dont have the torque. They have reasonable hp but they dont have the power. They only have 680 watts.. not 800. I have many brushless motors in my rc cars.. up to 3 hp for a 25 lb buggy that used to have a 30cc gas motor. It works great for that .. but it does not have the torque to move heavy objects. The big brushed motors have big magnets and wiring so they can move a wheel chair or scooter weighing 200lbs or more. You say that the regulators.. ESC... are difficult to find, they are easy to find and are very cheap. I think that the motors you are talking about will not work in anything that is 1/6 scale. >I have many electric motors of all sizes and types.. for tanks you need a >tank size motor. >My 2 cents worth.. >Garnet > >On Friday, 29 March 2013 03:40:41 UTC-6, Niels Erik Kristensen wrote: >Why du everyone use big heavy and week brushed motors?
