I presently own a DX7 Jr Spektrum and 10 Rx's. I have not had a single glitch in 2 years of use. I use either the AR7000 or AR6200 rx's. Prefer to have the 2 rx's since that provides total directional reception,I believe. I mount them only with double sided tape. Since that tape has a thin foam layer it supplies some vibration insulation. I have not had any trouble. I fly electrics and glow. Main rx flat and satalite vertical at 90 degrees to main and antennas 90 degrees to each other. They can be had for several different prices depending on supplier. I use Todd's Hobbies. I'm sure you will be pleased with them if you decide on them.
