Transmitter for RC cars made from Taranis X9 Lite

thingiverse

My First Complex Project from Scratch Works Surprisingly Well I'm thrilled to share my latest creation, a Pistola transmitter with electronics from Taranis X9 lite inside. This means it's likely the first 24-channel telemetry transmitter for RC cars! I've packed it with endless setting possibilities using OpenTX, logging capability, voice messages, and even a secondary controller via trainer port or wirelessly. As an early beta version, this project has been slowly developed and modified as I built the real transmitter. Not all parts fit perfectly together, but they work well enough. The throttle and steering wheel mechanics are from Himoto, and you can use different ones with just a little redesign. Everything is made of PLA, printed on my Prusa i3 MK2. You'll need around 40 M3x10 and 2 M3x16 screws, along with 3 M3 nuts to screw everything together. The PCBs and controls are attached with their own screws, while some parts are glued using superglue. The complex parts, such as the steering wheel panel and LCD panel, can be printed in one piece or separately and then glued together. It's up to you! However, I'll redesign the battery case soon due to its difficult sliding cover and poorly designed JR module holder. For now, it's not a priority for me. During assembly, you'll need some soldering (unsolder the PCB with an expansion connector, remove and attach the antenna, extend some wires) and purchase a longer FPC cable that connects the mainboard to the TX module. You can use the original cable, but the Tx module will be in a less-than-ideal position. The two holes on the connector panel are originally designed for a power switch and 5mm 3-color LED. The antenna holder can be glued to the back of the front panel – it's unglued on the photos. You should print the corner four times, of course! I hope assembling is straightforward enough that you won't need a bigger documentation, but if you have any questions, feel free to ask. So, download, print, enjoy, and modify! Photos and some modifications will probably be added soon. If you want to help, the blender source file is available on https://drive.google.com/open?id=1SpqS6wu6WTXdYKaxTYd7VznZc7YsVvIq – it includes useful additional objects like an M3 screw puncher and another Ferrari logo. Thanks to other designers whose products I've been inspired by or partially used: * nonoducati: https://www.thingiverse.com/thing:3100368 * dmyers7: https://www.thingiverse.com/thing:692350 * Painless360: https://www.thingiverse.com/thing:2456788 21.8.2019 – I added some photos of the controller prototype. The sixth unused hole on the steering wheel panel is an unused hole, originally designed for two potentiometers but now used by a switch. I plan to move the switch to the bottom panel and use these holes for potentiometers (two axes from the second joystick/gimbal). On the photos, you can see the prototype without center screws on the middle of long edges. To make the case more stable, I glued it instead. Oh, I almost forgot about the battery holder! I bought a simple one for 18650. Some assembly guide was added (assembly_guide.txt). A little bit more ergonomic handgrip was added, and you should print bottom_panel2 too. 5.10.2019 – The source blender file is now in 2.8 version. Improved ergonomics for controls on the steering wheel panel were added, as well as a redesigned battery holder so that the front panels (battery holder and front panel) are in the same plane. The JR module holder was also redesigned, and the battery cover was reworked. I'll make some photos after I print all the new parts.
