|  XXX-T What motor
Just picked up a XXX-t roller i'm going to put a brushless system in it. Was thinkin about a Castle system 4600,5700,or7700 it will be used on the track most of the time. Going to run it on a 2s 5000 pack.

Since you are limited on voltage, I'd say the 7700  My T4 is stupid fast on a 7700. I stuck a 5700 in it and just didn't have enough for the ridiculously long straight up here at my local track.

I run a Mamba Max with the 5700 motor on 2s 5000 in my Stampede. I love the torque, its hard to keep the front down. I get up to around 45-50 mph or so on the street, almost fast enough:neutral:. I would go with the 7700 though, and then you can change power by using a few different sized lipo's.

5700 no doubt. I've run both a 5700 on 2s and a 6900 on 2s in my B4 and the 5700 is much better. More torque and can handle more voltage if you ever get a 3s or something. The 6900 will run a little hot racing and the 7700 is only good for high speed passes which gets old. |
