Jackal

i had decided to switch to the Atomic carbon CR2 for next season and started to collect the necessary parts together, whilst waiting for the nose section to arrive i did the 4th gear mod and prepared the rest of the CR.

but then i saw the Aluminium chassis and the 4 gear plate and thought i would wait until those came out. so with everything ready and having a couple of days free i started playing around with Autocad and pro engineer.

one thing led to another and i sent the drawing to a laser company and they sent these back

So off to the milling machine and a few hours later we have this

Now this is a prototype so a couple of errors were spotted but not enough to stop me carrying on.
will post more later

I started to assemble

as a temporary measure i dremeled the original battery holder

using the rear end of the cr i attached to the chassis and then removed the centre bracing, the reason for this will become clear later

attached the complete front end exactly the same as the cr2

the gearbox, when i started the design i made provision for the cr gearbox to be attached, however i also drew up a aluminium internal 4 gear box in pro engineer, to get this box CNC milled as a one off would be expensive and there was no guarantee that the car would justify it, so i had a problem, i didn't want to use the CR box as the idler gear mod is a bit exposed and to have mounting holes for both boxes was not practical, i have however an S2 4 gear box, a bit of measuring and adjusting the pro engineer file would allow me to use this S2 box and when the new box is made it would drop straight in.

first job was to strip and clean the S2 box

I modified an existing CR shock tower to fit to the car, the new planned box is designed to allow the Losi tower to bolt straight in without mods.

however a quick check with the S2 tower and it fits without moving the geometry around too much so i decided to use that

Thats the car pretty much assembled so on with the fitting out, pretty standard stuff for a 2wd, speed passion ESC, Orion Vortex 6.5, Trakpower "dark" saddles, KO standard size servo, a half height one would give more space but i managed to squeeze it in without problem

Looks very nice Jackal

Bodyshell and wing, i had an old S2 wing so shoved that on, managed to fit a losi shell with a bit of cutting but needs a bit more investigation, i had an old shell belonging to another racer which i somehow had possesion of so rather than paint some thing quickly i put it on to test run.

weight is 1650g that is without any extra weight added, tomorrow it gets its first run so we will see. any feedback gratefully received
