4WD Straight Axle SC truck

[NickRummy]

Yes I know it's been done before but I want my own

I started designing something like this years ago. I sold an MT2 to a friend a while back and ended up getting it back missing the diffs. So I thought what the heck, might as well start slapping parts together

I'm going to do a tube chassis on it. I'm not sure how much though. The rear end for sure since I plan on that being exposed. Instead of cutting on some aluminum plate and doing a ton of steel work only to find out I put mounting holes in the wrong place I decided to make a mock up chassis out of plastic. The final rear portion of the chassis won't look anything like this at all but this way I can make the chassis swiss cheese and find the right mounting locations for shocks and links and then use it for a template when building the final setup.

Wheels are only for mock up too. Turns out they have the right offset so I can just match that with a better looking wheel set. Rear shocks aren't final either. They're only 90mm eye to eye so I'm not getting the travel I want out of the rear end. Something around 100-120mm will be perfect. These lipos are for weight mock up only. I'll be using smaller packs that fit on this chassis.







This is just a box sitting in the front to hold the body up. The track width is nice and wide now.



I need to stretch the wheel base just a tad but I can do that when I make the final links.





Here's the drop out with the 90mm shocks.



Up travel won't be a problem.



As for power. I don't want to drop a ton of money so I'm thinking about trying one of these? Should put me right around 30mph on 3S which I'm thinking would be decent for my local tracks and some bashing. It's going to be around the weight of a monster truck probably. Anyone try these?

I also have to figure out how to take the outputs from the hyper 7 center diff and convert them to a standard 5mm shaft to make it easier to find center drive shafts.
