I run two of these in my CEN Racing F450. I have experimented with 6 or 7 motor and ESC combos in that vehicle, these Spektrum ones are permanent. Smooth and can go pretty slow as well. I use the F450 as a tow rig and it does great pulling a couple TRX4s. Have a 3rd on hand that I will probably put in a trx4.

This thing is bad ass! I run this in my Axial Ryft Crawler build with a Vfd Twin Transmission,paired with the Vanquish 43/13 ring and pinion's,absolute unit! The FOC technology is such a bad ass feature. Order this for your Crawler. I guarantee you won't be disappointed. I just ordered the 2300kv one. I don't even have anything to put it in but I know I want it lol
