RE: Emcotec/Smartfly/Powerbox
I have the Emcotec DPSI Twin with computer interface, two 5000mAh Longgo LiPo batts, the ICE display and filter capacitors for both receivers. The switch design is simple and confidence inspiring: it will not switch off unless you physically move the pin from one hole to the other. The Emcotec stuff is extremely high quality, well designed and well made. I highly recommend it.
