RE: Which Reciever?
I have a few each of the 555's and the Electron 6. These are solid performing dual conversion receivers. The Electron 6 is the smaller of the two and the ones I have work flawlessly. Range is the same as with any of the 8 channel RX's. I use them in my electric planes and in a .25 sized plane and have had no problems. I use mostly Hitec equipment.
