Technik RC

Great project — a 6x6 Mercedes build sounds amazing! Yes, our dual-input differential supports power output through two differentials, though please note it cannot be locked. If locking isn't a requirement for your build, it should work well for your setup.

Regarding using 2 motors on a central shaft — yes, this is possible as long as both motors spin in the same direction, which is achievable with our system.

For your ideal configuration, we'd recommend:
- Porsche Brushless RC Set (includes receiver and controller)
- 1x additional brushless motor with 1/16 planetary reduction
- 1x additional differentials

A: Power Functions is the original plug-and-play IR remote system — simple, but limited in range and speed. CONTROL+ adds Bluetooth, an app, and sound/feedback for a smoother experience. Third-party performance boosters plug into the same motor ports but deliver noticeably more power, pushing top speed beyond stock LEGO electronics — at the cost of faster gear wear if the model isn't built to handle it.

A: Typical range is around 10 meters (33 feet) under normal conditions. Low batteries or obstacles between the device and model can noticeably shorten that effective range.
