Tactic TTX300 steering angle increaser

thingiverse

I wasn't thrilled with the stock radio's steering angle, so I created this gearbox to boost the distance the wheel turns from 100° to 170°. You'll need: 2 x 12 x 18 x 4 bearings 1 x 5 x 10 x 4 bearing 3 x M3 x 5 button head screws 2 x M3 x 8 screws 1/8" or 2.5mm drill bit Phillips head screwdriver (Hex drivers or hex keys if you use hex head hardware) Installation: 1. Remove the steering wheel from the radio by prying off the small cap in the center of the wheel, removing the screw, and taking out the steering wheel. 2. Insert the 5 x 10 x 4mm bearing into its intended slot in the main gearbox. 3. Place the main gearbox centered on the steering post at the desired angle, then place the main gear on the steering post and insert the second gear into the 5 x 10 x 4 bearing. 4. (For this step, it's recommended that you disassemble the radio to avoid damaging its internals; I'm not responsible if you ignore this and destroy your radio) adjust the mesh between the two gears, then use one of the gearbox holes as a guide to drill a hole into the radio, insert an M3 x 5mm screw. 5. Insert both 12 x 18 x 4 bearings into the gear cover, then install it on the radio but don't screw it on yet. 6. Adjust the mesh of the gears again to ensure smooth operation, then remove the cover and drill a second hole for the other M3 x 5mm screw (you may need to remove the main gear). 7. Attach the main gear using the original coarse thread screw. 8. Using the M3 x 8 screws, attach the cover. 9. Install the original steering wheel with the last M3 x 5mm screw.
