My setups

Slash 4x4 Steering - ACE DS1015
Works very well, with ample speed and torque
Endpoints (travel) set at 75%
Requires glitch buster cap or external bec with some ESC / RX combos

1/16 Erevo Steering - KoPropo PDS3101
Awesome performance, fast and strong
Slight modification required to fit


Cheers
