Tank Track 2in, Track, grousers, sprockets by fastmike75

Last crawled date: 3 years, 1 month ago

Tank tracks are a remix/redesign of Thingiverse 163486. Tank tracks are redesigned to work with these sprockets and has a different track pitch of .775". Use brad nails (listed in instruction) to hold the track together. Tracks are 2" wide and I have tested them to hold up with Brushless motors and Lipo batteries printed at 20% fill. I tried 11 different design changes before finally getting these right and they hold up far better than I ever expected. It was a lot of fun trying to break them!
Tracks can be used with or without grouser bars. Grouser bars give excellent traction (except on smooth concrete!) and no metal contact with surface (unless you wear the grouser down to screw). There are holes in the flat surface of track to mount grousers.
Drive sprockets are designed to work with ServoCity .770" hubs. This should make it very easy to get drive motors, gears and shafts to run track.
You can design your own tank or see my things for all of the 3D printed suspension, gear boxes, idler wheels, frame rail drawings, body and electrical parts to build a complete tank from 1/8"x1 1/2" flat aluminum rails and metal angle brackets.
Some of the pictures have Vee's built into the track for traction, the tank just ripped them off. Grouser bars work much better and way more traction.
The tank in the picture has 94, 3D printed track segments, 47 per side.
There are two YouTube Videos of tank project. One video with dual Tamia/Mabuchi RS540 motors controlled with Sabertooth 2x12. https://www.youtube.com/watch?v=dRz3TS2hO10
The other video is a 120 second gear box meltdown with Traxxas 38,800rpm Velineon 3500 brushless motors VXL-3s ESC and Dual 3S Lipo batteries, I figured the gearing I have, tank does about 11mph. https://www.youtube.com/watch?v=DlbDo2PSruk
The tracks hold up really well.
Just added a Tank Track that is 1.94" wide, same as remix track, so you can stay the same width if you have already started.
Also added a grouser drill guide to drill holes in track in the right place for grouser bars.
Update: There are more pictures of the tank in the photo gallery at fastmiketanks.com.
Update: Have updated Kyosho Gear boxes 2694014 and different suspension arms and wheels 2699624 for this tank in my things. There are also CNC machined frame kits, motor rails and parts on ebay under the same name, to help you build a working tank.
