Polk’s new system is nice. I used Paul Norton’s at Fred’s during the Invasion. We did have one glitch during the ops. For some reason the TX just stopped controlling Paul’s MU diesels. Paul was able to get it going again, but I think he had to re-bind the TX and RX to get it going again.
As Tony observed, a lot of us water boilers already own a 5 channel 2.4 GHz radio system, so this softens the blow to get started. I don’t remember how much teh basic Spektrum RX unit is, but at about $125 US, the Beltrol is a lot easier for me to buy than the new TE.
Now, if you could come up with an after-market kit to mount the Spectrum TX electronics in something a little easier to carry around, you’d have a grand slam. When I saw the name, I thought that’s where you were taking Ric’s idea.
