I've searched for this mod that apparently involves simply resoldering 1 wire, but can't find it here or Google.
Could someone point me in the right direction? Pics would be nice too.
Thanks

More information would be good - are you referring to the Tamiya or Heng Long Leopard 2A6, and what do you hope to achieve with the elevation mod?

There is a mod on the Clark web site on how to due it for the TK boards if thats what your looking for .

If you mean the mod that allows you to...

1. use the airsoft cannon synchronized with the shell / reload sound...
2. Control the elevation motor to run in BOTH directions instead of cycling through in one direction. (on a mode 2 transmitter - it's LEFT stick at 75% up from the bottom and then use left and right movement to control elevation up and down)

Then follow my guide here...

Need to reconnect (or resolder) 1 wire. Basically its a splice.

Then you need to SWAP the position of 2 other wires with each other on one of the plugs. See photo on the guide on which wires and what it should like look.

Heng Long. So far, just to have proportional up and down. I'm removing the Airsoft.
I'll check out the Clark site

Either way just do what I did, it fixes it.

The TK22 site is HEAPS confusing. It took me ages to figure it out. I didn't follow the photo guide.

I looked at the control board specs for a tk22 and which wires should be connected to which pin on the main tk22 board. Then worked backwards and traced out all the wires

There's a table that displays this info. basically in stock form, some of the wires are connected to the wrong pins on the main board. SO it's just a matter of swapping the positions.

More specifically I used this chart and diagram...

The plugs you need to look at are CN9 and CN3 (middle column with the HL airsoft / recoil)



Where it says gun elevation motor TWICE for 2 pins, it doesn't matter if its negative (-) wire or Positive (+) wire.

LED's though need to have the correct polarity to function.
