crazyjr, yup that's me. Hope you are enjoying it.

There's a thread on rctech with much more information than the rclaps site. The cost of the transponders is $65 with free shipping, so it's cheaper than the AMB's. The added convenience of having the same number was well worth it for me, not to mention it's a much better transponder that has replaceable wires, works down to a lower voltage than the AMBs (good for my 4 cell 1/12 car) and it puts out maxx signal strength all the time.

It took about 3 weeks from the time I sent it to the time I received it back. Return shipping was less than a week.
