I added a lemon RX with ppm out to my Taranis to be used for a wireless buddy box. I also added a small momentary switch, hooked up to the bind button, so that I can bind it without opening up the TX, just turn on the TX while holding down the button.
I hooked up the ppm out from the rx to the trainer input of the tx, and found a switched power connection to power the rx from.
I used a 5V regulator, but in looking at the specs, I don’t think I had to.
Make sure when you mount the tx, it is not in the way of the movement of the sticks when the case is closed. I just used double side tape to mount the rx. With the TX case closed, you can still see the LED of the RX if you look through the small spaces in the gimbal (may need low light, and to look from different angles)
Once you have the rx connected, you need to set a custom function to activate the trainer and to calibrate it for the buddy box you have bound to the rx.
Long press menu
In this menu, when you move the sticks around on the buddy box, you should see the numbers at the bottom move around.
Click + and – to move around the page, go to each mode and set to := (for replace channel when trainer is activate)
Set Ail and Rud channels to -100, this way you can bind a blank model from a speketrum tx, and everything should work.
Use + and – to get to the Cal setting, then press enter, set buddy sticks to center (including throttle) click menu to reset all numbers close to 0....Continue Reading
then I cut the wires off the end, and added in 2 more wires (one positive and one negative) and wired them to a small socket. Then drilled a hole in the back of my battery cover, jb welded in the socket to the battery cover, and put the new lipo in the TX. Now I plug the Dragon link into the trainer port and the power port, and this turns on both the DX9 and the DL.
I started with the WL Toys quad and got the attachments. I really like the attachments, but donít like flying the quad so much, it is way too mushy for me. So I got a blade 180qx board, and put it on the WL toys frame. The board mounting holes did not line up so I used an old gift card, cut it to size, poked holes for mounting and mounted it like the old board. Then double sided taped the new board to the gift card.
I got an RC Switch to activate a couple of the add ons, cut off a connector from the stock board, and wired up an adapter to activate them.
