About this Blog

This is about the combination of two interests, Radio Control vehicles and Science Fiction models. Its also about vehicle design. The models have to satisfy two main precepts.

1. The vehicles have to work, ie be driveable, but not nescessarily win any races or rock crawling competitions.

2. The main thing is that they have to look cool.

Creeper 6X6 part 3

I was pretty unhappy with the look of the body sitting so high on the chassis. I contemplated abandoning this body and trying something else ( this would have been the second body to be abandoned for this project). Before committing to scrapping the body, I thought to try lowering the stance of the chassis a bit by the use of some shorter shocks, to see if that would improve the proportions enough. I found some red anodised shocks on Ebay from China for $5.00 a pair. That's an incredibly cheap price so I figured what the hell, if they're crap and it doesn't work I haven't lost too much. As it turns out they are well machined and nicely finished except ... they are not actually filled with silicone fluid but with a tiny amount of some mineral oil and the pistons are a really loose fit. I cleaned out all the oil and filled them with silicon fluid but with the pistons are so loose in the bore and have two slots rather than holes, they don't do much damping. However they hold up the chassis and it doesn't look too high now so I am continuing on with this body. They also look a lot better and match the anodising on the wheel beadlock rings and suspension links, plus the black springs are nicer.

I also started on outfitting the electronics into the chassis and actually took it for a test spin... it works! The turning circle is large compared to the 4 wheel steering of the toybash truck, and it's even larger when the diffs are locked, however it climbs well. The center axle is at this stage unlocked as it does not have the switch mechanism being made out of  the axle halves that don't have the molding for it. I am thinking of permanently locking the diff for that axle for the superior climbing performance.

The Turnigy Ubec will supply the power for the lights via the nylon connector in the photo above. I also got some switch boards from Pololu.com which will allow the lights to be switched on and off from the third channel of the radio control. This was suggested by someone on the RPF forum where I have been running the Toybash truck project at the same time as this blog. Its really tiny, smaller than a postage stamp and I haven't wired it in yet to see if it works, that's the next task.

Happier with the sit of the body I couldn't resist filling in the detail well on the top and started some panel work.

The tranparent blue parts at the rear are two halves of a little water pistol that comes in party prizes. Anything made of the right sort of plastic, styrene, ABS or acrylic is a candidate for use as detail parts. The white domed shapes are the buttons from a scrapped washing machine.

More soon...
