Well due to the increased crawlers on the forum i figured why not have a thread like the mugen/kyosho/losi threads.

ok let the crawl talk begin.



ok i have an idea to make a buggy drive train based crawler (like how maxx and savage crawlers are made) think this would work?

idea based off of this...
my savage/scorpion/tuber project - RCCrawler.com Bulletin Board

think what would work???? maybe Im not seeing a picture or something... I used to run an e-maxx based truck, tube chassis, maxx trans and axles etc... it was fun but supers get boring to me, they just laugh at the rocks. i did see a tc3 based build on RCC a while back...it was realy sweat, the guy made custom molded CF axles.

Large RC 4x4 Chevy truck with tube frame, independant + - eBay (item 230215264473 end time Jan-27-08 17:33:49 PST)

Somebody might be able to snag this cheap enough with that vague title.

The "independant" suspension on that must be like the "Inline" V-6 in the '04 Mustangs (don't laugh one of our old employees at StC's Dad was told that at what once was Sycamore Ford.)

what i was getting at was the buggy center diff stuff would that be ok to use?

Get an axial tranny or a pede tranny. Axial is bulletproof for $38 brand new

well i have a full TXT/Juggernaut tranny. its just at bubbas right now

what "buggy" diffs are you going to run? All this talk about supers lately is going to push me back into building another emaxx trcuk.....must resist!!!!

Kyosho 7.5 diffs

they could be used but, might take a bit of work....I couldnt find many pics of those and Im not very familiar with them myself... can you get spools for them? Looks like they have cvd outputs, will you be able to get long enough cvd's??? How will you build the axles around them? I dont mean to discourage by any means, these are just questions you need to answer before you start a build.. Bring them with to the Club meeting on the 2nd, I would like to take a look at them.

You don't want a "Diff" on a crawler (Front. rear OR center). The problem a diff will cause, is when a wheel or axle gets stuck (Which will happen while crawling), it will lose all power to that axle, and just spin the other wheels. You want to run a locked front and rear axle, with a locked tranny. This way, all 4 tires are always getting power.

Look into a Scorpion tranny, it has a VERY big gear reduction, which will send a lot more pulling power to the wheels. Also, look at a solid axle setup over independent suspension. both will work, but the articulation of an independent suspension, will keep the tires parralel longer, not letting the "working" part of the tire do it's job. Crawler tires get the best bite from the surface of the tire, very little usable bite from the sidewall.

yes i was going to lock them some how. and for making into a solid i was thinking about doing the same type of thing that is on the savage.

here is the diff

Travis.... Just sell it on ebay and pick up a "meant to be" crawler...

i wont get anything for it and i thought this would be a fun project

they make lockers for savage (i.e. and 1/8 diff)

Traxxas made a Spool also.

I think a buggy company makes a spool
maybe ofna.

Foams question...

I got those losi rock claws, they have relatively firm foams.

I have some old foams from jumbomaxx tires, and i cut them to fit. The thing is though, they are one strip not a loop.

With the speeds crawlers go, do I need to glue the ends of the foam back together or will it be ok (no worries of it splitting/overlapping)?

one axle down one to go. i ditched the home made solid idea after looking at so more maxx crawlers and just went with a lock out and it looks alot better i used revo push rods for the top "arm" for now need to get some turn buckels cause wheels are looking like this

\----/

pics up later

lockouts are what 80% of the maxx people use

Foams..... take the stock foam and cut it in half so you end up with enough foam for 2 tires....then basicly cut triangle chunks out (starring)

^HACK! lmao. j/k.

I've been practicing star cutting on some old foams. Getting better, then I find some really soft foams from jumbomaxxes laying around in a droor of mine, cut them in half and to lengh and man they feel good in my claws.

Mmmm my tcs order came in... pretty sweet.

thats not me. just a pic i found to help illustrate.
