Hey Gary,
Sonny Brown just emailed me back and said to try it with a receiver pack as well in the 12th scale. Both of the ones that wouldnt bind were in a 12th scale with No receiver pack....but the 3rd one was in the same car and it worked

. I am going to try it here in a bit with a receiver pack and also try it in my TC if that doesnt work.
Both the TC and 12th scale have MRT Speedo's and the 12th scale has a 9602 Futaba servo.
Michael Skeen bought 4 of the Micro receivers and only 2 of his worked as well. When you turn them on with the bind plug in it only flashes twice and then goe's out. The one that worked in my TC keep flashing as it supposed to until it was done binding with the radio and has worked perfect for 2 weeks now.
Thanks for the help.
EA
