Rango - Build diary

[Ellis]

Hi guys. Tormenta 2 got pretty knackered last year, and whilst we'll probably patch it up and get it running, it'd be nice to have an all new machine for the champs. I'm building and funding this one solo, so I've spent a few months brainstorming/designing/cheapening and in the past month or so, ordering parts.

Rango is a 4WD machine with a small drum up front.

Some details, feel free to skip!..

-Construction: 15mm 7075 aluminium weapon bulkheads with 20mm HDPE sides, 1mm ti base (non structural), 5mm HDPE top. 12mm HDPE back panel, 3.2 or possibly 4mm hardox wedge on the front.
-Weapon: ~2kg "drumette" doing around 9k rpm.
-Drive: 2x Johnson 885 motors @ 18v (about 600w each) powering 75mm wheels, around 15mph top speed.
-Speedos: TZ85s
-Battery: one of the 5s 30C Optipower packs, probably 4300mah.
-Radio: anything I can get cheaply
-Things: stuff

Quite a few parts have already arrived/I've started to make. Still need to get the battery, 3 speedos, weapon construction, hardox front end, etc.

The main aspect of this machine is its drive. It's essentially a rambot with an electric flipper on the front.

I had intended to make a simple machine as my first solo build, which I have completely failed to do. And I'm pretty late on starting so chances are this'll be riddled with reliability issues if it's even complete by April. I bought a hobby lathe a few months ago so if nothing else it should have some nice shiny bits. :P

Will update with some pics of what I have so far at some point. For now, that's it, cheers.
