JR Quattro Mode 1 to 2 modification

This is a fairly easy solder job but not reccomended for the novice as it intails working with SMC components.


WARNING!!!!!!!
Don't do this unless you are willing to possibly break your radio..



Step 1:
Remove the Battery and Chrystal,
Remove the 6 x Phillips head screws holding the radio together.

Step 2:
Move the Ratchet, Level and Level Spring to the desired position.

Step 3:
Remove the 4 microcontroller PCD retainer screws

Step 4:(Point of no return)
(if radio is in mode 1 move the Bridge (0ohm resistor) from red to green) and other way around if Mode 2

Step 5:
Reverse the stripping process and test.


if all is good RX Channel 1 = Throttle and corresponds to the throttle stick
