Project 005 : SumVee HDE (HEAVY DUTY EDITION)
---Part 1 : perfect rear steering (4WS)
I had considered updated project 005 with rear steering via the "summit standard rear steer system" (similiar to what is detailed in the Summit FAQ, THE SAME SYSTEM EVERYONE SEEMS TO BE USING ). But I wanted something sturdier, with stock perfect geometry that would not succumb to bump steer. So I went back to my project Funky Gecko.
In that build I decided to "simply" cut 2 chassis in half and install a complete front section onto another complete front section (with the front section being longer than the rear, project Funky Gecko ended up becoming a 1/6 scale rig).
But this time along with a duplicated front steering section I wanted to keep the original summit size and dimensions, along with complete battery boxes.
Step one was to purchase a 1.5inch x 8 inch steel "backbone" to support the rear (front) section.
and created a second complete front end out of spare revo parts
next was to dremel-carve a niche in the chassis to seat and support the backbone firmly
pre-fitment was rather impressive. later I will drill some holes and pop-rivet the back bone to the chassis for additional sturdiness
Drilled some holes into the backbone to match the stock bolt pattern (what a pain) and cut a section for the diff lock actuator
and bent it ever so slightly to match the bend in the stock chassis
overall fitment looks impressive
the length is not perfectly spot on, I realized that I needed a few more cm to fit a servo on the end of the chassis. kinda hard to steer without a steering servo. but size wise it is still within acceptable specifications
the weekend is here and its time to play with the kids, will update with the steering servo placement and support bracket next week.
