I use the futaba 14 channel RX's or sbus, so shortage of channels never comes to mind.... Makes sense to use powerbox then! My viper was done when I bought it, I only re-did the layout inside. I have this pull cable thing for the canopy release that is a mystery to me, but works very well. About three inches back from the canopy there is a little wire pull. I circled it in the pic.
