So last night I ran into what I thought was a really good deal on a Castle 1406 5700kv 4 pole motor. I bought it with the thought of sticking it in my Rusty. My son convinced me it was worth a try in my Pede 4x4
So I got a chance to run it this morning thinking it would over heat but much to my delight it did not. I have it geared 12/54 and a heat sink from a Villian boat on the motor running on G Loc tires. The speed calculator puts this set up right at 50 mph. Motor temps on the can were in the low 130º range while temps on the fins of the heat sink were 150º at the end of a 2s 5200 mah pack.
Truck was noticeably faster than it was with the 3800kv motor geared 17/54 on the same tires. The 5700 is shorter and presumably lighter than the 3800 but I did not think it would be enough to make any difference but the truck did seem to be jumping further and higher then it did when the 3800 was installed and just felt a little lighter on it's feet, this may just be in my head.
Not totally sure if this motor is going to stay in my Pede 4x4 or find it's way into my Rusty but I must say I was impressed with it in the Pede and if it does not cause any issues with more use it might just stay in the Pede.
