Hobao Hyper is the only truck/buggy that has been suggested and it's just what i have been looking for. Not too small, 4WD and spare parts are easy to find. Certain it doesn't have camber? Would 1/10 rock crawlers do the job? Any bigger crawlers available? This is what i'm trying to do http://www.msuk-forum.co.uk/gallery/image/30733-axle/

Motor size is based on the instructors experience from previous years. I assume that planetary gearbox allows the use of such tiny motor.

Hi I'm building a autonomous robot(university project) that should navigate on a corn field. Our team doesn't have any RC knowledge so help would be appriciated. It will resemble that Basic structure Four wheel steernig, four wheel drive One motor+steering servo per axle RS540 motor + gearbox Team xray xb9 central differentials coupled to the gearbox with a gear Custom stiff axles We need Steering knuckles Wheel axles+hex nuts and bearings Dogbones It will go quite slowly (~1.5m/s =5.5km/h) and be heavy (under 20kg) We will have to shorten the dogbones(differential won't be mounted on the centerline) If the wheel axle and it's dogbones are not compatible with xb9 differential it won't matter We want tight turning circle and crab steering Wheels will probably be custom made (milled plastic+glued tread) Requirements Strong dogbones, small dogbones won't survive the cutting and coupling Strong wheel axles, one axle snapped during previous competition Knuckle with no camber, it will look funny and make our instructor unhappy. We are trying to keep it simple so no caster blocks. Bonus points We have two leftover cnc knuckles for Kyosho mad force if the new knuckles would utilize mad force compatible axles we could use the leftovers Good availability in europe(need to get spares fast when we break it) Any suggestions?
