Re: 1/10 Caterpillar D8T Build (3D Printed)
That looks like a really good start!
Which 90 deg. gearmotors are you using for this? Any idea how much force those tracks can hold before something goes pop?

well, this build will be mostly for show and for the pleasure of seeing it run, so yeah, dont really know whats the max stress the tracks can hold, lets just see how long till the first one explodes... Last edited by Orange RC Works; 01-20-2023 at 11:27 AM. |

Re: 1/10 Caterpillar D8T Build (3D Printed)
Thank you, i thought it looked like that's what you were using. I'd been considering those for a project. Any idea what size motors those use?
Sorry, I wasn't sure if you were planning to try staying plastic track, or prototype a few then send it off later to be printed in metal. Can't wait to see this one come together

Re: 1/10 Caterpillar D8T Build (3D Printed)
At first i thought it was too slow and underpowered with a couple of 2S lipo batts, but when i changed to a 3S set, it changed dramatically.... and i think the speed kind of matches the full scale ones at full throttle... i had it climb a 20 degree incline and it climbed pretty good until the tracks starts sliding on a smooth wood surface lol... i think im ok with the power system and it did not get hot at all (motor & esc)... so i call it a success. thanks

Re: 1/10 Caterpillar D8T Build (3D Printed)
Yeah good call, 3s makes more sence for the 12v motors.
3.7v, 7.4v, 11.1v Your prints are looking really nice

Re: 1/10 Caterpillar D8T Build (3D Printed)
Thanks, I actually do post print processing to smoothen the edges and re drill the holes etc... the bottom of the print usually flare out on my ender 3 so i have to file it off more so when i have to join two parts together, i just hate cleaning up material removed from the prints lol...

Are they just N20 motors....

Re: 1/10 Caterpillar D8T Build (3D Printed)
It looks like you are controlling the motors with just a toggle switch. Do you have any end limits on your actuators?
If you have the limits installed, I'd be very interested in seeing how you pulled that off. I've got several projects in the works where end limits on the actuators would be nice to have, but as usual with most RC projects, space is at a premium. Ten pounds in a five pound sack is a good description for a lot of projects. You said that you are using the M3 version of the gearbox with the threaded rod output as your actuator screw. What are you using for the nut? I know you've got this type of actuator on your powered ramps, but they won't get used as much as the ripper will, or the blade if you use the same type of actuator there. Any concerns about lubrication and/or wear of the screw/nut? Don |

Re: 1/10 Caterpillar D8T Build (3D Printed)
Yeah those are n20s.. I have some like that of various rpm's so I can make my own cylinders like you did... been kicking the idea around for a while now just haven't started on them..
Did you print the inside of the cylinder to fit the nut or just press it in.... I have some of the brass press in threads I want to try too.... |

Re: 1/10 Caterpillar D8T Build (3D Printed)
I see.....
The rod, a cylinder in a cylinder... so you don't see the rotation... That was my thought... It looks good in 1/10 I'm not sure if I can get everything small enough to look right in 1/16. I might have to just deal with seeing one cylinder rotating.... But thank you for showing the exploded view it helps a lot... |
