    Darin thanks for posting this info. I did not realize they would bind. I've tried it with a couple of my rx's and it wouldn't. Maybe its a hit and miss thing.

      Steven,

      I got a chance to talk to the gentleman who was having the issues last night, and after hearing what was happening, I suspect that the radio had little to do with the problems. And, you are right... it won't bind if they aren't both marine compatible TX and RX. I found out last night that his was the Marine TX as well, with the MR3000 RX.

      The story goes like this. Install radio and seems to work fine on the bench. As soon as he gets out on the course, the boat goes for a bit, then just dies, "like a nitro boat losing it's glow plug". Same story for heat two. "Almost like you had to bind and rebind while out on the course". Some more tweaking around and then no issues at all for round 3 and 4.

      It sounded to me more like the RX was losing the BEC connection and going into failsafe mode. Was in a 1/10th scale with older wiring setup in it that could have had corrosion or ??? and was connected to an AquaCraft ESC that "had been around the block". Likely had been used in a P-Spec Hydro or who knows what else over it's lifespan.

      Directly connecting an RX pack was never tried, and the radio system is now owned by someone else, so we may never know for sure, but I'll be in touch with the new owner as well, and if there are any issues with his setup, then I'll take a closer look at the radio system itself. Otherwise, it sounded to me like something other than the radio was causing the the RX to go into failsafe do to loss of power.

      I'll update as we investigate it further. Just wish I'd been there to help, because I'm certain I could have figured it out, and instead of people thinking that the Radio was the problem, they might otherwise realize that the radio was actually saving their model from being destroyed by doing exactly what it was designed to do.

        I have a DX3 which is not marine compatible, can this be upgraded to marine compatibility? and if so how much would it cost? I just gave away one of my FASST sets and have this old DX3 sitting around unused, over here FASST RXs are about £90=$135 so if I can get the spektrum upgraded to a usable state and a MR3000 RX to suit for that price or less that will be an alternative way to go.

          I have the DX3S and wasn't impressed at first. Thats because I was using the RX that comes with it which is not a marine RX.

          Then I got the MR3000 and have had no problems since. I like that I can use one TX for all my boats. And I love how small the MR3000 RX is.
