Hello, I want to start a topic for all my WIP mocs for help and what not, and a place for all my unfinished projects or ideas. I'll start off by posting some pictures of my buggy chassis, with 2 l motors and a servo, and all wheel suspension: Posted Image
Posted Image

two l motors for drive, geared down once, and tires spin off startPosted Image
Posted Image

Posted Image

good suspension travel... Posted Image
with simple body.. Posted Image

Well, I found that picture right after the post, at the time I had only pictures of chassis, because I took it apart for my upcoming Crawler V2 Posted Image

Looks like you could fit a standard AA battery box in there as well. Nice!

Interesting design.  Haven't seen another one quite like it.

Thanks, I guess I could share some interesting models I built long ago, in case anyone would like to see more than pictures, like explanations or just discussion, like my modified version of zblj's raptor... Posted Image

A tip for people who use these tires on these rims- DO NOT LEAVE ANY WATER IN THEM! Because you'll take off the tires days later like me  and go Posted Image from the smellPosted Image

I really like the shape of the raptor mod.
Not a lot of technic models have that sort of roundness. :thumbup:

I am away from home so no pictures but is it possible to connect four L motors together in a sort of planetary fashion? I am thinking of doing this for a offroad buggy or crawler, one thing for sure... it will be BIG im thinking like two motors side to side, and two more on top and bottom, each with a 24t gears, in this shape-  + with another 24t in the middle

OK, been messing with LDD (its a pain for me), and came up with this: Posted Image
m motors since L's dont exist in ldd.     change of gearing for offroad- Posted Image

ok, getting the hang of ldd, made a start to some kind of chassis, braced everything up, and I think i'll do this rather than buy a bunch of buggy motors because my dad has the final say on what I buyPosted Image (its his money until I get a job)
so two more L motors it is! Hopefully this will work-whatever it isPosted Image Posted Image

Blimey.:blush:
It's a good idea to support the motors at the back as well.

yes, it will be easy because of the L motors' many pinholes, here is just m motors as a placeholder for the L's.

I don't see any adder in there like I suggested in the other topic.
With out one you will loss a bit of power and also your motors will heat up with the strain.

Im not sure how to do an adder with all these motors...any ideas would be helpful though. as for strain or heat, my rally car does heat up, but only if its put under decent load or running nonstop for a while...  Posted Image

I look forward to what you come up with, im guessing something like two motors on each side of a 5x7 bracket, and a differential in the middle, with (image) part on each side so motors can be parallel with the bracket? lol if I read your mind.

If you find that it is too wide for your moc than you can always put one on top of the other and then add gearing to join them together.:sweet:

@ z3_2drive (a.k.a. max butvinik):  That's a fast Rally Car!  If you put it into your Crawler, it will be like a Baja 1000 racer!

I think there are too many power losses:

1) knobs generate too many friction
2) model is too heavy and tires are grippy - central differential is very pleased

With 4 L motors it have to go much faster than in video...

Try
