Guys

I've been using PowerBox systems for around three years now, I started selling them two and a half years ago and so far my seven models haven't missed a beat.
Sales account for another 50+ units they again have been 100% according to customers reaction and re orders.
If you look at the manufacturing of PB equipment, its fantastic quality.

The advantage is that the servos are decoupled from the Rx-no interferance from long leads.
The signal is boosted, this helps control feel and effective range as the servos don't get into stepping as early as they would without the boost.
Voltage output at 5.9v is perfect for JR or Futaba servos (JR quote no 6v packs-5cell as they are a lot more than 6v when fully charged)
The two batteries offer back up and going for Competition or Evolution versions have fail safe switches so that they fail to on...switch on and you can remove the switches!

This is as good as it gets so far...
