My CR-01 Jeep Wrangler

we love commenting on new trucks lol!
As per Aperture's request, here are the piccies.

The battery I was using was a hard case battery out of my savage flux and quite heavy so I got rid of the top battery mount plate and made a small, light weight alloy one mounted to the front diff above the servo.
It moved the weight down lower, but also allowed me to use a smaller battery.

The springs are also out of a savage flux HP, they're slightly longer than standard springs so the whole car sits up a lot higher but the weighted wheels help keep it on the ground for the most part.
I also run without the windows because I found that the extra weight is just enough to make it topple over at our favourite quarry. Eventually I may just get a lexan body for it.

The lower plate I made myself because I wanted to experiment with the link positions and to give the base a little more rigidity.

Specs: LRP Crawlwer motor + ESC
Spektrum DX3r radio
DualSky 2100mAh battery

There are more pics Here. Forgive the JD bottle, it helped me build the car and is there to give an idea of how much articulation it had when I built it.

After an eventful day I managed to snap the rear driveshaft completely off on the male side. I decided that wasn't going to stop me so after a bit of bush mechanic engineering I came up with:


Unfortunately I didn't get very far on front wheel drive only before THIS happened:


Which caused the male side to shorten so far that it only just fits into the other half.

Life's pretty straight without twisties!

I'm disaapointed... I didn't see any JD Bottle there!!! Razz

Nice rig, I want to see it traverse the tunnell, the driver must get one hell of a nose bleed from that height.

and can't beleive the twisted drive shaft, now thats torque.

The JD bottle is in the link to more pictures on photobucket.

I've tried to go through the tunnel, it's too wide as well as being too high. Since I posted those pictures I've shortened the springs so it sits a bit lower, but the wheel base is still far too wide for the tunnel. Maybe if I put the stock tyres & wheels back on it might but then I can't get up any of the hills Sad

Tamiya give you spare shafts in the kit so in a pinch I can put those in but with any luck I should have some steel ones coming.

I found the tamiya ones to be useless Mad
However i had a heap of old ( can,t remember the size now ) but i think it was 5mm allen keys
So with my spare set of tamiya ones i shoved an allen key thru the guts of the licorice stick ( gently using a hammer ) and then cut to length with a hacksaw . Never twisted the shaft after that .

I just got some traxxas ones and one of them was a straight fit, the other needed to be shortened 10mm. They're a fair bit stronger in the part that fits over the the star looking thing so that should at least prevent them from simply popping off. Let's see how they hold up to the torque though.

I discovered I had what appears to be glass reinforced fly mesh "cat proof" fly screen stuff.

Makes for good radiator grill material:


I either got it from Bunnings, or Mitre10 but it's probably available at most hardware stores or any place that sells fly screens.

Well after tumbling down the hill and breaking part of the window frame on my hard plastic body I figured it was time to retire it for something lighter and more flexible.

I'm tossing up between using the back end that came with the cab, or making a tube frame of some kind. Maybe a tube frame that allows for the use of the matching lexan back .



edit: Started on a tubular frame for the back end.

Started making a bumper template tonight for something to mount the winch on.






Thoughts? Tips?

edit:
Here's the first try, it's pretty damn dodgy. I tried to make it all out of one piece but surprise surprise, aluminium is harder to fold than paper Surprised so some of the folds are a little off. Or story #2 is that it was made that way so it looks like the car has been in a few fighting matches with trees & stuff Razz
