How To Install the MR-02 AD board into the MA-010.
PICTURE 0- MR02 AD Board set-What comes in the box.
Heres the AD board setup. There are a few things different from the MA-010 board, besides the obvious. First you see there are three POT wires. Secondly the ON/Off switch wire placement is different. Lastly, the plug is on the bottom side of the board.
PICTURE 1-AD Board spread out.
So the general swapping goes as followed.
1. Change the connection to the other side of the board.
2. Change the servo motor power connections.
3. Extend the ON/OFF switch wires
4. Replace the ON/OFF switch with the MA-010’s
5. Dremmel out a hole in the top plate for the new connection terminal.
PICTURE 2. Heres the pin we need to remove.(Sorry about the blurry photo I get my camera back later this week from the shop.)
Mark the inside of the connection with a pen so you can place it in corrently. Just keep the same side of the pin toward the inside of the board. This makes sure you can plug in the connection to your computer and the pins are still lined up correctly.. So remember to keep the same pins in the same holes...
To remove the connection just place some solder wick on the connection pins on the top side of the board. Heat the wick and slide out the pins.
Heres what it should look like.

Next we see two pieces of the board that don’t allow us to sit the connection down all the way. So we need to file down the connection to make it sit all the way down.
PICTURE 4-In this photo you can see where the connector goes-purple- and the offending pieces of the board-red arrows.
So you just grind down the connection and it fits like a charm.
PICTURE 5-Dremmeld down connector.
PICTURE 6-Assebled board.
That’s the hard part. Then just reverse the servo motor wires- Red and Black..
PICTURE 7-Servo wire swap. The purple arrow shows what wires to reverse.
Insert the New Pot into the servo unit. Swap On/Off switches, add in a ½ inch of wire to the ON/OFF switch wire.
Lastly just dremmel out a hole in your pcb cover and you are ready to play.
PICTURE 8- Car reassebled.
Then you can set your EX-10 or mars controller on super high speed and enjoy how much faster the car responds.
This is an invitation for anyone to comment, either good or bad (on all my posts)... Please we post here to help each other out. If i did somthing wrong or bad let me know, or if there is a way to make it better please let me/us know.
As long as its not... Your picture is fuzzy. - I know my good camera is in the shop...
@ sciencemike you didn't do anything wrong. I just don't want to step on your tutorial (toes).
Ok here goes the suggestions/alternatives
On the on/off switch you can use the AD one by snipping the 2 metal tabs off. Swap the 2 white wires around. Solder the long one to where the short one is on the board and on the switch. Put the short one where the long one was on the board and switch. These are now long enough without extensions or making new wires.
If you are not going to screw the pos and neg wires from the board to the wires from the battery box on the inner plastic cover but solder the wires direct from board to battery box tabs, you can just snip the center fin on the plastic cover to make enough room for the white computer connector to fit. No need to remove and mod the connector. The center fin is the vertical piece between the screw holes in the inner cover.
