Have you heard of the Tiny Trak? If not, it's definitely worth checking out - it's just so adorable! I got my wheel file from a great resource over at Facebook, and everything started there. https://www.facebook.com/groups/181517579149618/ However, the original design requires gluing the drive wheel to the servo shaft, which is a bit of a hassle. So, I made some modifications that make it easier - now it won't slip and you don't need any glue. Here's how to assemble your Tiny Trak: 1. Print out the file. 2. Use a knife to scrape away at the edge of the middle hole, just like in this picture. 3. Cut a flat spot on both sides of the servo shaft. Start by cutting just a little bit first and then try to push the wheel in - it should fit snugly. You don't want to cut too much or you'll end up with gaps everywhere! 4. Screw the wheel onto the servo. You'll need the following parts: * A receiver: I'm currently using this one, which is on its way from Banggood. https://www.banggood.com/DIY-FRSKY-8CH-Receiver-RX-PPM-Output-For-X9DPLUS-XJT-DJT-DFT-DHT-p-987247.html?p=DG23031123036201501P * A 1S to 5V booster: If your receiver works at a minimum of 5V, you'll need this. https://www.banggood.com/Matek-DC-DC-Voltage-Booster-1S-Lipo-to-5V-Synchronous-Step-up-Converter-p-990756.html?p=DG23031123036201501P * A 9g servo: I've found that these Towerpro servos spin faster than the HBK Hextronics ones. https://www.banggood.com/6-X-TowerPro-SG92R-Mini-Micro-Servo-9g-2_5kg-For-RC-Airplane-p-1164389.html?p=DG23031123036201501P * A micro VTX: This is a great little camera for your Tiny Trak. https://www.banggood.com/5_8g-48CH-25MW-VTX-600TVL-NTSC-FPV-Camera-for-Eachine-QX95S-QX105-Micro-FPV-Racing-Drone-p-1235875.html?p=DG23031123036201501P * A 1s 45C Lipo battery: This will give you plenty of power for your Tiny Trak. https://www.banggood.com/5PCS-Eachine-E010-3_7V-150MAH-45C-Upgrade-Battery-USB-Charger-Set-RC-Quadcopter-Spare-Parts-p-1103569.html?p=DG23031123036201501P
