We might experiment with ramping up speeds when we get the drivetrain built, but until then, we are focusing on actually getting it built.

The cylinder isn't mounted on this plate, I didn't want to attatch anything to that plate in case we end up taking it out. that 3rd plate is just simply extra support to prevent sagging.

Sorry, should've worded that differently. I realize that the cylinder is mounted to the second plate. When I said mounting, I meant gearbox to chassis.

Would it be at all possible for you to post the CAD for this gearbox? I myself am in the process of designing a custom gearbox with ball shifters for both a PTO and for shifting between two speeds, rather than using a dog tooth for the PTO as you seem to have done.

Oh man, I never thought this thread would come back up. I'd love to post the CAD, the only problem is that it's so old I'm not sure if I have it anymore. I'll dig around and see if I can find it and post at some point

Thank you in advance, traxxasracr1.
