Small update

Since posting the first rendering. I have “refined” it a bit more (I think)
Also I have changed the waterfall slightly to take a B5M battery bar. Did also cross my mind to make it hinged but this works for now and means theoretically you can just but a B5M bar and use it. Also grooved the motor mount to aid cooling and generally chamfered lots of bits to make it look pleasing to my eye.
With the chassis opted for a hole were the gear box would go, as it would be cheaper to cut a hole that mill a pocket out then to protect the bottom of the gear box I have made a skid guard/small rear bumper



I have ended up with 2 possibility’s:

Normal as we shull call it. Basically when the low gear box is on the chassis there wasn’t quite enough room for a saddle pack. So I have just made the chassis/battery are abit longer, just enough to just fit a saddle pack in.
However after I finished it realised there isn’t much room for ESC and the stuff you need


Click for 3D viewer -> https://skfb.ly/Twp7

I then looked to rectify this my making it longer (approx. the width of an ESC) my only concern with this one is that the wheel base may be wayyy too long.
On this version I have also pocketed out the would be 3D printed side pod bit so that brass weight can be added within them Think I will also do this to the above one, calso keeps print cost down.


click for 3D Viewer -> https://skfb.ly/TvZY

As I a way Farley happy with the gear box, that is now being printed in SLS Graphite plastic stuff (not via shapeways) via a similar website. Chose this stuff due to its graphite content should make the gear box a bit stiff and more durable that the standard plastic stuff (I presumed its not to dissimilar to the old losi graphite plastic)
in my haste to get it printed I have ended up print a MK1 (1st image) waterfall brace not latter one show in this post.

Once that arrived ill try and post some pics up, then ill set about

A: getting a proto chassis made in acrylic got a local guy who can laser cut one
B: Hack up my older/oldest CR2 chassis Drill a few extra holes in it and see what happens.

Got these this morning in the post!

overall very happy for my first proper attempt and a start to finish proces (design to manufacture)

Also very pleased with the material choice.i feel the graphite SLS will have better stregth properties

Cant wait to get home and start mocking it up.

So had some time this afternoon to take a closer look at the bits i had 3d printed.

i decided to make a prototype chassis to make sure

A. The 3d printed gear box fits/clears/bolts in

B.to get a feel for how low it would look

C.Get a rough handle on the wheel base of the thing.


This picture shows how much longer the chassis relative to the atomic extended wheel base chassis.
This is the negligible option as i wanted to try and keep it as close to a cr2 as possible. the other option i have is to make i quite a bit longer but would need to do a check to see if the wheel base would be ridiculous or not.
the extra length is needed to accommodate a saddle pack due the waterfall brace pushing a saddle pack further up the chassis.






Also made a very "crude" motor mount (not my best unfortunatley) but again just to give an idea see were things were at.
















The out come of it is.

Motor mount = fine.

Gear box- tweaks needed.Had to cut a 2mm x 1mm slither of the rear of the gear box to get it to sit in nice and how it should. will also need to relocate the hole were the screw goes threw the shock tower/gear box/shock tower.
as it does not quite line up.
Also going to address the side of the hole needed in the chassis where the gearbox goes into.now looking at it on and a psychical chassis i can play around wit the bulge on the gear box get it shrunk

other than that rather happy

Probably have to wait till next payday (snoreee) to get more bits printed and get the gear box internals.
Think i will complete the mock up then once happy get a chassis cut and should be straight swap(he ses)

CR2L is born!
(L is for Low or Liam...)
