E-Maxx Stick-Crawler

Hi!

Yo, the next project to do...

I was a little bit sluggardly to develop an own direct-steering so I simply used the original one...

Wheelbase will be about 19,6". I got to find the 4 steering rods and some strong links for the chassis tomorrow, we´ll see...

looks pretty good for a start

looks nice i would like to see how this goes

wooow 19.5 wb is crazy, what you running jumbo kongs?

[Uncle_Manuel]

Thanks guys!

Hmmm, I have the Jumbo Kongs but they are reserved for another project. The Maxx will have the black cutted wheels for first. Perhaps I´ll try some 40-sized tyres later...

And no updates on this long weekend --> party at a friend´s home with lots of meat (barbecue grill) and alcohol...

Thats big.

looks good, but i think you are going to have a hell of a time getting the revo shafts to extend out so far without leaving them room to not slip. if there is about a 1/4 inch in to the female shaft, they will start to slip under load. good luck

Uhm, look at the position of the diffs and than add the layout of a stick-crawler - voilá!

Or in other words: This will be a layout with independent motors... ;)


I´m working on 3 projects right now so updates will follow these days...



...later...




...or so...

I did notice that the pinion shafts were on top. Are you going to make this a top loader. I have thought about doing this before with some worm gears for added reduction and self braking.

I have also thought about using a small planetary gearbox at each of the wheel hubs for reduction. The full sized monster trucks use this method to keep from breaking axles.

[Uncle_Manuel]

I´ll use a 1:50 reduction gearbox each axle, that should give enough power and smoothness for crawling. Disadvatage is the the mounting of that thing to provide the advatages of the stick-chassis...

I am really curious to see how you get the motor mounted...

[Flip]

Another idea that I've had was to keep the pinion shaft horizontal like it normally is and afix a gearbox to the pinion shaft. The gearbox goes up to where the motor is attached above the center section. The motor sits parallel to the pinon shaft. The Heim joint is then attached to the top of the gearbox giving you a good amount of ground clearance.

The only problem with the worm gear top loader idea is that the input shaft and drive shafts will be off center compared to the Stick. The only other way to use the worm gear idea is to build an axle from scratch where the worm gear arrangement takes the place of the differential.

Hi!

Finally some new pics: ;)

But I got to rebuild it. The chassis is too loose and the servos can clearly move in their monts under loading. So what´s the deal? I´m planning to strip it down to the naked axles and restart at point zero. Perhaps I´ll try the stick again, perhaps I´ll do something different - there´s at last a complete tranny from the E-Maxx that is gettin bored...
I´ll keep you updated... ;)

That motor setup is hella sweet man!! Sounds big to, nothing better than a super rig!!

[Uncle_Manuel]

Thanks! That geared motors (1:50) are impressive and very powerful. At 6V they deliver an axle-breaking 400 N/cm (don´t know the conversion for the american measures)! And I´m using 14,4V...

any updates on this rig? I've seen a couple other maxxes like this with stampeded trannys mounted on each axle on the skidplates and heared it was a go anywhere machine? Hows your setup?
