Datsun Pickup build - Resurrection of Big Bear
 
Bit of background to start, my dad's first hobby grade RC was a Marui Big Bear. He loved that thing. 17 years ago, he stripped out the gears trying to fit in a small space at high speeds. It has been sitting dissassembled in a box ever since, till earlier this week.

Took the body to work, and in my spare time I made up a frame

Cutting in half, used an angle grinder and a nice tapeline

Welded in supports, and threw on some paint. Its not done yet, I still have yet to finish my welds, but I want to wait untill I have suspension parts and weld on the brackets.

This is a mockup, with aproximate ride height and tire size (about 3 in OD)

Thats all I got so far. Tomorrow I am going to add body posts to properly mount the body. I will update as I can afford parts, the big thing right now is axles cause there dont seem to be any used ones on ebay. This by no means will be a full out, hard core crawler, but more of a trail runner that would be used for mild crawling at most.

Cheers guys!

More done today, made some body posts. In a right pain in the butt to drill a hole in a round rod, but I did it

Po mans body clips

Then I started to make a sheetmetal canopy. Personally I dont like the look, but its a good spot to house my radio and battery and whatnot. I will have the back door on a hinge and magnetic latch thingy. This is my improvised bender, the vice isnt even bolted to the table

And I am this far, the window that is against the cab windo is welded in

Ive been looking at chassis all weekend, and almost none sit like mine do on the truck
http://i1083.photobucket.com/albums/...81ADF7EB29.jpg

And I wasnt happy with it, nowhere to put electrics other than in the bed under the canopy, and that setup would have given me a high CG.
I came up with this, pretty standard shape but I am happy with it. This id just a template, made from a coathanger. My next chassis will most likely be made from solid 1/4 inch round steel stock, Im out of box tube. Due to my lack of knowledge with 4-link geometry I will probably leaf this.

Cheers, gonna see if I can get this new chassis bent and welded tomorrow

what axles are you gonna run MRC, i built a bigbear awhile back i think the bodies are kick ass, i took the easy route and used a l-trail chassis, subscribed to build

Thanks man, If I can find a set of MRC axles cheap enough I would go that route, otherwise Id be getting the cheapest axles I could find and narrowing them

Re: Datsun Pickup build - Resurrection of Big Bear
 
there was a set of mrc axles in the classifieds a couple of days ago for a decent price

Go with some 1/16th [wheels with cut and shut tires I think everything else will be too large, looking.

Re: Datsun Pickup build - Resurrection of Big Bear
 
Im visiting my mom untill thursday so Im away from the truck, and bored. So I made a practice leaf spring from a cheap tape measure that decided to crap out.
http://i1083.photobucket.com/albums/...5A500DCFFC.jpg

Its a 3 leaf pack. I like the stifness but these wont be used. I dont know how long the actuals need to be and this recoil stuff is only slightly wider than 1/8th of an inch. But now I know how to make em, kinda.

Also made a bungee cord. My first attempt works but looks a little funny. I will probably add some heat shrink tube on my next ones
