I myself have not tried it, but i have thought about it. Dont forget the vortex is a sensored brushless mate. As said previously in the castle creations thread, there designing an update to allow the use of sensored motors with the mamba max, you can run a vortex with the mamba, its just that the vortex might not run at its optimum performance, because the ESC is sensorless. Hope that clears things up for ya!!
What I have - Brushless Slash 4600kv, DX2S
What I need - Boss Motorsports 10.5, TRC LCG chassis, Ford F-150 SC body, Proline Protrac & a Brushless XXX-T CR MMP4600kv. Not alot!
