Oliver Cletrac inspired chain tractor

thingiverse

I designed the farm tractor on a scale of 1:6, using it as a driver every 1:6 action figure can be used and I chose the Oliver Cletrac HG 42 tractor as a prototype. Some parts are glued together, others are positioned with magnets, the backbone of the construction is the two square tubes. Here's a video of the first indoor test drive: https://youtu.be/zu37hACGBpY Parts required for completion include: 2 CHIHAI MOTOR 12V DC Gear Box Motors - 50 to 80 RPM (RB Motoren) 2 speed controllers and a transmitter with mixing functions, or a special chain controller 2 10mm square tubes 220mm long 12 round Magnets: 10mm x 2mm 62 chain bolts diameter 3mm metal or carbon 20mm long 2 nuts M5 for the drive wheel 2 grub screws M5 25mm for the drive wheel 2 self-locking nuts M6 for the lead wheel 2 screws M6 40mm for the lead wheel 4 ball bearings 6x13x5mm for the lead wheel 6 nuts M4 for the chain guide 6 screws M4 x 16mm for the chain guide Here are the drive components I used: I drive with a 12-volt setup, battery = 3s 1500mAh 12-volt Motors with 80 RPM: https://www.banggood.com/12V-DC-Metal-Gear-Reducer-Motor-High-Torque-DC-Gear-Box-Motor-p-925500.html?rmmds=myorder&ID=512747&cur_warehouse=CN Speed controller: It is essential that the brake can be switched off! https://www.banggood.com/Waterproof-Brushed-ESC-160A-3S-with-5V-1A-BEC-XT60-Plug-For-112-RC-Car-p-1030025.html?rmmds=search&cur_warehouse=CN I do not use a mixer for tracked vehicles, I mix the two motors in my transmitter. What has changed: 13.02.2020 - Assembly instructions added 15.02.2020 - Information about the electronic components that I use 11.10.2020 - new power drive (read PDF) I chose this engine: https://www.banggood.com/Zhengke-ZGB37RG-12V-60rpm-Reduction-Motor-DC-Gear-Motor-37mm-Eccentric-Shaft-Output-p-1296605.html?rmmds=myorder&cur_warehouse=CN Of course, this engine also works fine: https://www.servonaut.de/shop/de/product_info.php?info=p529_getriebemotor-rb35plus51.html
