Hobby Lobby Hunter/Tornado suspension arms

thingiverse

Longer suspension arms for Hobby Lobby Hunter & Tornado RC cars from early 80's are now available. Common to both front and rear, these upgraded arms feature: * Track will go up 60mm total * Zero caster and camber - except for rears, see below * Upper arms designed to maximize shock travel and angle within space provided, creating a more damped feel, but you may need to adjust spring perches * Lower arms designed to accept anti-roll bar end links * Bump stops setup for ~40 degrees total movement, ~20 degrees at max droop and compression, helping keep dog bones from popping out and binding against drive cups Front: * Front A-Arms have print in place ball joints; rotate the ball 180 degrees before use to firmly hold front axle knuckle king pin pivots * Reuse existing hardware, but source a few new parts Rear: * Upper arms designed for equal length suspension, causing wonky geometry with negative camber at full droop and positive camber at full compression; correct the geometry by making upper arm shorter or creating a new taller rear hub * "It's fine" for bashing though Required parts: * 4x HPI Dogbone #101064 (or any dogbone 90mm long from center to center with 8mm drive balls) * Longer steering links * 8x M3 x 18mm screws (for bump stops) * 4x M3 x 25mm screws (for shocks) * 12x M3 nylock nuts These upgraded arms are likely to bolt right up to Robbe Pantera, Serpent Cobra, and Graupner Hunter models. They will definitely bolt right up to Skyward Labs Mean Mudder models. Update Nov 25, 2017: Untested part files added for 1' camber all around, 10' caster up front, and 1' toe in in the rear; printer issues prevent printing.
