Jon, great to hear. I've been wondering about how you liked it ever since you said you were trying it again. Good to hear.

JanisK, one thing to remember is that some drivers have contracts that state they must use all one type of radio equipment, including modules and receivers. You also have some drivers that DO use the equipment yet do not declare it! For example, the winner of the ROAR 1/10th Sedan On-Road Nats used Spektrum equipment. He never listed it anywhere...in fact he even listed a regular frequency on his on his sign up sheet and showed as much on the mains lineup sheet. I've also talked to a former IFMAR Champ about this down at Snowbirds. He mentioned to me that the person he gets his radio equipment through said not to use it because of the lag. Nothing from first hand experience. One of his Team Mates then made a great point to him which really got him thinking about giving it a shot: The latency in the Pro system now, today, is much much less than what his radio had that he used when he won his last WC. It was an interesting point. Sure I'd like to see more Pro's use Spektrum, but it will come. Spektrum users have won in classes at National events all over the country. Just off the top of my head, Spektrum users have won at the IIC in Vegas, The Tamiya Nats, Roar Fuel Nats, RC Pro Series Regional and National events, Roar regionals, Euro's, and more. And not to name drop, but just to name several top drivers who DO use Spektrum equipment, there's Frank Calahandra, Steve Slayden, Travis Amezcua, EJ Evans, Sonny Brown, and of course now the INfamous (which means very famous- 3 Amigos) Jon Kerr

In the great scheme of things, I wouldn't worry about who is and is not using it. I know I don't. I just turn on my radio and run...
