Something maxx-related with more than 4 wheels.

I'm wondering how hard it is to learn to use one of those things, I'm thinking that it would be nice to make the battery compartments of the ERevo a little bigger to accommodate some 4s or 5s batteries in parallel. Many of the packs I see on the web are a little too large to fit. I'd love to be able to make the battery compartment up to 10 mm taller and maybe 1 or 2 mm wider. Do you have a good plastic welder to recommend?

Thanks

Ok, did some more work today on the "Project X" , which will be a 6x6 lst based truck.

1st up was removing the stock steering setup and replacing it with a muggy system. This cures a bunch of problems for me. I am not fond of dual servo steering setups, and the lst setup with the servo mounted savers is a bit sloppy under power with large tires. The muggy setup has a std 1/8 style bellcrank mounted servo saver, and a very solid tiebar holding the cranks together. Plus the muggy has basically the same bulkhead and suspnsion setup as the lst, so the geometry and tierods are all correct. I will have to make a new chassis plate for the truck, as the steering servo will not fit in either of the stock locations. I plan to turn it 90 deg from stock and place it just behind the current servo holes. This will allow for a short link between the servo arm and the bellcrank.

2nd was to fit the pass thru diff into the rear bulkhead. This was very simple. I just removed the rear bumper and rear bulkhead support and repaced it with a muggy front bulkhead support. This is the part that sits on the back of the front bulkhead on the muggy, just in front of the steering posts. It fits perfectly, and has a support for the nose of the diff that points rearward. So the pass the diff is fully supported on both ends, so I doubt that I will have any issues with it. I need to make something like this for the maxx 6x6, as the rearward pointing nose of the pass thru diff is currently not supported...

The driveshaft that will connect the pass thru diff to the rear diff is just a lst1 wheel shaft with the cvd cup of a center driveshaft on it. I am using an ofna hyper8 diff cup to accept the dogbone end of that driveshaft. Pretty simple, and the parts are off the shelf, a big plus IMO! i planned to use a lst2/muggy wheel driveshaft, but the ball end of the shaft is bigger the center driveshaft cvd cup. Luckily the lst1 wheel cvd shaft fits with no mods.

The rear suspension assembly is off my muggy, just using it to mock up what I need to order. It is completely stock, nothing modded save for the addition of the ofna drive cup. I plan to use lst shocks all around, and put the muggy back together... i have almost all of the parts needed to build another bulkhead setup.

Power system will be a hacker c50 11xl on 6s lipo with a MMM. I modded the tranny to forward only, but retained the manually actuated high/low gearset. That way I can have a normal high gear for bashing, and then switch into low gear for some crawling/climbing. Going to run 6 moab 40 series tires (not the xl) on beadlocks. Gearing will be for around 35 mph in high and whatever I end up with in low. Braking will be via the MMM, no mech brakes for me!

I still have to make the extended rear skidplate and upper brace. These will tie the rear and center suspension assemblies together. I also plan to use a set of the muggy chassis braces to tie it together diagonally. I may also make some side supports out of thick plastic to tie the skid and upper brace together and form a box section. I plan to bash this truck, and jump it, so I want it strong.

Time to go to the hardware store and pick up a new blade for the bandsaw, so that I can cut the 6061 al sheet that I just received. Here the pics, the wheelbase is 23" !!!!!!! So this beast will be big!
