Jimmy j from all that has been said here and elsewhere on RCU you should by now have knowledge of what is available. We all have absorb info then make a choice based on what we think will be best for us. I chose JR Spectrum for several reasons that suited me and have not any a single problem of any kind with it in over 2 years. I have it installed in 16 of my aircraft and fly them all often, some nitro,some electric and one gas. I do suggest that you not buy anything less than 7 channels.
