Using A Spektrum Dx7s To Control The Ex-B3

I am exploring the idea of using a Spektrum DX7s (RC Transmitter used with RC cars/plans and boats) to communicate with an EZ-B3, thereby controlling two brushed motors? The design's current configuration is:

  1. One EZ-B3
  2. Two 7.2volt NMH battery's at 3000mAH
  3. Two ESC ( Traxxas XL-5, Electronic Speed Controllers)
  4. Two 7.2volt brushed motors and transmissions

The 2.4GH receiver connects the DX7s to the BZ-B; the EZ-B connects to the ESC's; the ESC's connect to the motors and the batteries connect to the motors.

my questions are; 1. which add-on 2.4GH receiver works best with the EZ-B?; 2. since the batteries are connected directly to the motor, is it still necessary to cut the trace?

Any help will be appreciated.

Attached file has a Visio drawing of the circuit.

It's not that simple , if you want to use a dx7 radio then get a spektrum ex and use regular motor controllers like you would a car or boat. The ezb must be connected to a pc running ezb software either directly or wireless with Bluetooth. , but I know dx7 has a cable to plug it into a pc and use it as a gaming device

Arobers: personally I can not see the attachment with the picture, I would like him to talk about it, I have a futaba radio ff7 and I would like to use it in combination with ez-b, ie the robot can be remote control by radio rc and also by self-ez-b. We may have to connect each receiver channel for each digital output of the ez-b with servo Y-cables, but so pwm pulses are directed also to ez-b and not think it's good Perhaps some system to allow the ez-b output PWM input but not to damage the circuit. I think a very interesting topic with many possibilities.

I forgot, I use a cable to connect my pc rc transmitter to use the rc flight simulator, but this makes the wireless station is not but if it works to set it as a joystick. The cable I bought on ebay.

R2D2, You should use an RC Multiplexer to switch between sources. This is what I use: http://www.robotshop.com/cytron-8-channel-rc-rx-multiplexer-2.html
