Big Al-RCU

Was shopping at a local salvage store that had acquired a large hobby shop inventory and saw a rather neat receiver. It was a 5 channel that incorporated a 30A motor control. and was labeled Hitec Electron (I think). But wanted to check specs before getting it, i.e., limited or full range, etc. Nothing like that shows up in their website. It is not the Electron 6. It was about the size of an FM-5 and enclosed in heat-shrink. Anyone know what the specs might be?
Thanks,
Al
