Nearly Quad Symmetric
Posted: Sun Jan 29, 2017 2:26 pm
Got the urge last week to finally put this project together. It's a different take on a quad-symmetric suspension using RPM truck conversion arms up front and what started as a Trinity wide nose graphite chassis. The RPM front arms are 2.25" pin to pin while the stock width RPM rears are 2.23" so it's only nearly quad-symmetric. 
The chassis started off as one of those Trinity chassis with the Hot Trick width front kick-ups. The kick-up was cut down so that the inside front arm mount holes became the outside holes....making it slightly wider than an RC10T front kick-up. The original plan was to use stock AE buggy front mounts but I found that the Traxxas mounts matched the width of the rear arm inside hinge pins better than the AE ones. As it is, the inside front and rear hinge pins are maybe a few hundredths of a mm different, while the outside front hinge pins are wider than the outside rears by less than a mm per side.
Of course I had to design a custom front shock tower to work. A big thanks to Gomachv for cutting it.
I wasn't really planning to do anything custom at the back of the car but I decided to bite off Masami, and mod/flip the rear bulkhead (like he did on that car Asso-man! now owns), when the only spare rear bulkheads I found in the parts bin all had cut up battery cups and/or other other mods done to them.
The the 10T tower got chosen because it had plenty of room to pass a trans brace through and meant I wouldn't have to ask Jeff to cut me another custom tower.
