Motor Adapter? How long?

How long is it going to be until the vex explorer to vex motor adapters are available?

I found out exactly how they should be built so its no biggy, you just take the same circuitry from the motor put it in a small sensor size enclosure’s and have a 2pin output for the vex explorer motors.

Here is the same circuitry that is in the motors, i got this from the how to add a non vex motor post.

Vex should sell the speed controller circuit lol that would be really really cool.

How much will these cost each, $5 or less i hope.
