I have a JR-R1 radio that I put a Spektrum DSM into. After I first had it installed I had Range problems, I sent it to Horizon for repair and they replaced the DSM unit. Everything was Ok for a while. I bought a new truck and new reciever for the truck, and now I am having range issues again, I get mabye 150ft away and lose signal. Is anyone else having the same problems or did I just get some lemons??? Im sure I'll be sending the reciever in for service or replacement It just sucks to have to wait 2- 3 weeks to get them back from Horizon.
