[MOC] 7 - 6 Mark 3

[CharlesD]

Hello,

I would like to show you my project it has been a year and a half in the making and is functioning pretty well.

 

- Christie suspension, spring loaded track tensioner
- 6 XL motors, easily reconfigurable to 4 or 2
- 1:5 Gear ratio, 1070 RPM - 8 KM/h @ 12V / 730 RPM- 5.5 KM/h @ 9V
- Gear ratio reconfigurable from 1:5 to 1:2.333
- 3 buwizz needed for ludicrous speed @ 1:5
- Two versions, 42065 inspired racing tank and "drone" shovel loader
- Stud.io files are available in the bricksafe link

Drives very good, the track tensioner keeps the tracks from throwing themselves off in corners most of the time.

I have been trying to intgerate a gearbox but it gets too bulky or can not withstand the torque required.

Any feedback or advice is appreciated!

6XL motors + 3 BuWizzes?! damn that must be a hella lot pushing power. Would love to see a video of that thing in action)))

It has been a struggle to get the motors to all work on the same drive shaft and keep the gears from slipping. I think i finally have the most robust setup also in regards to the perpendiculair final drive to the tracks.

Problem is that the weight keeps on increasing, to the point where i think the weight of two extra motors and support structure is not compensated fully by the increase in power.
