Default Trx4 Wide Project

Thought I would share a project I put together in case someone wants to try it or just curious. I was itching to do another out of the ordinary build. I had a Trx4 Sport chassis in a box for awhile that I wanted to do something with instead of just get portals and build it up I wanted to do something different and wanted a wide more stable at speeds Trx4. So I put xr247 axles under it with a 2 speed tranny. I measured out and tried the stock lower links to get the wb and did a little rod end adjusting and it was going to work. I used the rear uppers and a little red end playing with and it worked well. I first tried the panhard setup, I didnt like the position of the servo setup after some trial and error I decided to just 4 link it. The trx4 rails are tougher to drill through than I expected lol. I made some angled spacers to make up for the bend in the chassis and mounted the servo on the axle instead and it worked out good. Gearing was a worry because of no gear reduction in the xr247 axles so I went with a 35t motor with a 11t pinion on the 45t spur gear. I like the speed so far just on 2s, but I may gear down a little more on the motor. I still need to add a few things to complete it, but its running.
