I'm an old geezer going on 66 and no stranger to mechanics or R/C. Have been actively playing R/C Buggies and Truck/Truggy Bashing with my youngest son who is 37 going on what as i recall is @ 7 years now. So my draw to be here is CRAWLERS as the RC crawler.com site appears a wasteland of no contact or access.
So lets say HELLO and start out with a project I've shared over on the ARRMA forum, where sadly crawlers are not really spoken or seemingly cared much about.
Building with left over parts and pieces from upgrades done to other rigs, a bunch of fabrication parts, Utilization of ideas put to work I built this HYBRID CRAWLER based off the ARRMA KRATON platform.
Knowing IFS or full IS is not popular or generally given much attention ... My take was work with what ya got, think it and build it mentality .... Thus we'll start with an introduction of the base vehicle and give a few teasers to where it is now after @ 6 months of R&D and fabrication, mix-n-match parts applying etc ...
KRATON 6S chassis & base running hardware.
Putty lock up the differentials ( Not locked, but damn close )
Alter A-arm angles/drop, different shock towers & shocks increasing static height and wheel travel.
Place a 1/10 scale Outrunner Brushless into a 17-1 planetary gearbox and play with final ratios at center differential so it crawls SLOW with upper speed @ 10-12mph
High torque servos & steering racks,savers. External UBEC providing power, Bastens "Quad Steer" providing wheel steer options.
Adapt a Body off a Short course Truck, custom paint it and trim for clearances.
Put on wheels off an Axial SCX6 fitted with HYRAX XL's tires. Weight the inner hubs while doing so ( Lead shot in the inner wheel/ hub channel taped over & vented )
Do an exotic adaptation and take a second front end assembly and make it work in the rear creating 4 WHEEL STEERING. Place stiff aluminum upper A-arms onboard eliminating wheel torque flex on the a-arms ( No flex = No hop/wheel chatter )
Added additional BRASS weights to the front axle housings.
As it sits as a finished rig @ 16 pounds of All wheel IFS, All wheel steer uniqueness.
Really been a Fun Fun Fun project that where at now it Crawls and Paws it's way there really knarly ground and while to comp rig, it just works and works well IMO ... Subjective I'm sure.
If this post is of interest and folks here wish to delve deeper into all thats been done to create this one of a kind ARRMA KRATON KRAWLER ... would be happy to share & have that conversation with the community.

It had to be a little challenging to get the 4 wheel steer figured out on a basher.
