Woops, it's been a couple days... But the truck is now "finished" (with quotes because we are never actually done with them).
The servo mount is made from T-Maxx throttle servo mounts that were put in a vice to be narrowed with the help of a heat gun, were then cut down to let the servo sit lower, and were drilled.
Motor mount is 1/4" thick polycarbonate bent to a 90 deg. angle with a heat gun, and drilled to accept the motor and the screws to hold it to the chassis:
The brake setup uses the pads/rotor from the MT2, and an (obviously) custom actuator bar bent from steel music wire, that is held to the chassis with screws
. The mini brake servo is a Hitec 5245mg that was left over from when I put in a standard size servo onto the chassis for my CRT.5. That servo is simply servo-taped to the chassis.
The brakes are decently strong, certainly nothing too impressive, though
Next up was ESC mounting. Quite a pain, considering the size...
But I figured it out, and managed to incorporate the ESC mount into a brace for the motor mount, that will keep the mount from flexing (from the weight of the motor), where the flex could cause the spinning can of the motor to hit the motor mount. The brace/ESC mount mounts to the motor mount by 4 screws, and 3 screws hold the ESC to it.
Then I had to figure out a battery solution. I had a virgin Dewalt 36V pack that was out of the casing. I knew I wanted a shotgun-style pack (like the NiMh stick packs) because that's what would fit on the chassis. What I did was simply bend the tabs that were already between the cells, to give me a VERY simple 6s1p pack, that took all of maybe 10mins to make, with the only soldering being to attach wires and a Deans connector to it. It is secured to the chassis with industrial strength Velcro along the whole underside of the battery.
With the 4 remaining cells I plan on making the same style of pack, but shorter. The result will be 10s1p A123... Can you say POWER?
And here's another overall view:
You can see the custom rear brace, and there's a similar brace in the front that's kinda hidden, that attaches the front upper deck to the chassis plate.
