Hi George,

I've been using the 3ch SBus RX into a PowerBox SRS on a couple of models and it works great.

This approach is not a 'full' SBus system but gives me all the benefits of the Piwerbox, retaining all my existing servos, a single lead for 16+2 channels into the PB and cheap RXs. £55 for an 18ch RX basically.

The PB SRS also allows Futaba users the chance to monitor frame loss etc as well as run up to 2 RXs in satellite fashion if needed.

Try it! - I Wouldn't swap back!

Cheers
Mark
