Low CG Maxx

[nitrostarter]

So I picked up a 3905 Maxx roller, added a CC1518, 4s/6s and a MMM and had some fun bashing with it. Until I broke the stock chassis 2 times at the common breaking point by the bulkheads.

I didn't want to get another stock chassis, or buy the FLM(although I wish the G4 was still being produced...) so I decided to try something slightly different with it.

After having fun with some truggies on the track and enjoying their handling, I thought it might be beneficial to the Maxx to truggy-ize it. So I picked up some 1/8" 6061 alu sheeting, 12X24" in size and got to laying it out.

I measure the bottom of the stock Maxx from skid to skid and added 3/4" to the length for some added wheelbase. Then drew it out how I wanted it. I based the layout after the common buggy/truggy layout using the motor in the right rear, lipo on the left. I'll have the steering servo on the left front and the MMM on the right front.

The bottom plate still need some trimming but is pretty close to being done. Its basically a solid piece, eliminating the stock skid plate. The bulkhead bolt right to the plate. I need to fab 2 spaces for the center diff and drill a couple more holes. Here's the current layout and status:



I plan on using a strip of alu to tie in the front to the center to the rear, mounted at the bulkheads like the top of the stock chassis would. This will also provide a spot for mounting the receiver.

The center CVD's shown are Traxxas brand. The rear cvd will be perfect for both the front and rear center. So i'll pick another one of those up. I picked up a complete center diff from a Ultra LX of ebay for $8 shipped and a RC-M motor mount to pair with it. Steering will be handled by the stock setup and a Futaba 9351. Power will be a 1518 on 4s for now. Geared at 14/51 will be 42mph. I may have to throw in some LST diffs to add some gear reduction and durability as well.

I decided on the Ultra LX diff since the whole assembly was so cheap. But I also got it for the fact that Ofna has a center spool kit that drops right in for when I'll want the locked up MT feel. I'll likely pick up some buggy shocks and run a 4shock setup too.

With this layout, I can really slam the body post down. I'm thinking of picking up a Proline Bulldog body for the truggies and putting on it. Would look like with some Maxx Mashers!
