Powerbox (Smart Bus RRS) for Graupner - by Booma RC

This Smart Bus RRS power distribution system came installed in a giant scale airplane I bought recently. This is the Graupner version and since I fly on Spektrum equipment I have no use for it.

It comes with the touch screen display for programming the board.

It also comes with a mag switch and actuator that allows you to turn the plane on/off by touching the magnet with the actuator.

The whole system is no more than 12-15 flights old and was bought new with the plane.

The AR board combo with the mag switch costs $384 new. I am asking $225 shipped to USA destinations only.

See info below from the Bouma RC web site or click on the link.


26 fully assignable and programmable outputs

Looking at that next big project and wondering how you’re going to power all those servos, the RRS system is equipped with 26 fully programmable outputs, all via the single SUMD output on your HOTT RX. A single GR-12L receiver will give you access to all the channels of you Graupner TX. Each channel is freely assignable to any input and can be reversed and matched to any other channel on the Smart Bus. Building that next giant scale model. Smart Bus has got it covered.

Easy to Use

Smart Bus comes with pre-configured channel mapping that matches your radio so model setup is really simple. Of course for advanced setups all 26 channels can freely assigned to any transmitter channel.

The Next standard in servo Matching.

In the RC industry precision is key. How can you expect to be precise when no two servos are identical, giving you varied results no matter how well you mechanically match them. Match your servos across 15 individual points, with 8000 step resolution and you can finally achieve matched perfection on your elevators, flaps, multi-engines and more. Take the hassle out of your new setup and have a model that raises your skills.

Sub-trim and reverse on all outputs
Ever spent hours, mechanically matching servos and never being able to get them just right or had to use a separate channel on your receiver, just to reverse a servo. With our intuitive and simple setup you can easily sub-trim at the centre and end-points of all your outputs on the Smart Bus. Using Smart Bus you can individually reverse your servos at a touch of a button. Smart bus gives you ultimate power at your fingertips.

Regulated voltage gives you precise, repeatable, results.

It is hard to be the best with a model that changes. With our high powered 220A regulator FETS we remove the change and give you pure constant regulation. As batteries are used their voltage drops, changes in voltage mean changes in speed and power of your servos. Regulating ensures your model is the same time after time.

RRS - Redundant Receiver technology

Smart Bus RRS is the safest in signal sharing technology, the redundant receiver system ensures your model by utilising two HOTT receivers. Unlike other power systems Smart Bus reads signal from both receivers at all times and runs an intelligent algorithm to select the best signal.

In the unlikely event that a receiver fails then Smart Bus switches to the better receiver in less than one signal frame to ensure you will have constant control of your model. Reliability is key with models today, with our redundant receiver system you can ensure your model is always reporting back to you.

With Smart Bus all receiver events are recorded and remain even when powered down so you can review receiver health and signal strength between flights.

Vibrant colour touch screen display.
Gone are the days of fiddly buttons and rotating dial frustrations, no more bind plugs and small screw drivers needed. The vibrant Smart Display gives you feedback and simple programming all in one touch screen display. With intuitive buttons and a single setup design. Your model will be in the air before you know it.
