Convert you Dx2.0 to a dx3.0 free

[brushlessboy16]

Was searching around and ended up finding this neat little trick. The only difference between the 2.0 and the 3.0 is the placement of one 1ohm resistor.

By removing this resistor entirely you gain the computer features of the 3.0
-4 model memory
-Model naming

Features like
-Deadbanding (for those poor nitros)
-exponential curves
-Adjustable frame rate
- and the list goes on

By taking that same resistor and moving it to a different spot on the board you get the 3rd channel.


I wanted the four model memory and didnt have a soldering iron tip fine enough to resolder the resistor to the board so i just plucked it off with a screwdriver so my radio has all the computer features of the 3.0

Spektrum DX2.0 to DX3.0 conversion

By following this tutorial your DX2.0 will get all functions of the DX3.0. (3 channels, 4-model memory)
To convert the DX2.0 to a DX3.0, all you have to do is add a single (SMD) resistor, and remove one if you want the 4-model memory.
It has to be a 1K Ohm (that is 1.000 Ohm) SMD resistor, as shown here. (Dutch website)

The spot where you have to add the resistor:

The spot is marked with 'R43'.

The spot where you have to remove the resistor:


This spot is marked with 'R36'.

When the resistor has been added and the transmitter is switched on for the first time, you will hear a long (and quite annoying) beep and see an error on the display,
because of the extra functions. By switching it off and then on again all DX3.0 functions will be available.
After the conversion all settings are reset, so it might be useful writing them down before converting.
