RC Car Chassis Tolerance Fix (Hyderabad based)

I have an in-house 1/28-scale RC car prototype built with a 3d printer that performs well electronically but shows inconsistent handling on the track. The root cause is the chassis: several mechanical tolerances are off and I need a mechanical engineer in Hyderabad who can diagnose the issues, redesign the affected parts, and guide me through a small-batch manufacturing run. Scope of work • Axles and bearings – refine fits and concentricity, specify achievable machining tolerances, and update drawings/models accordingly. • Rework on the chassis for minor adjustments for better packaging of electronic parts, battery. • We are also thinking of printing custom domes for the car. This will be a scope for future work once the chassis design is perfected. • Wheel alignment – correct camber / toe errors caused by current suspension arm geometry. • Add front suspension, currently we don't use any suspension. for rear access. we use TPU printed mount which kind of acts as a small suspension which works fine. But, we want to include front suspension. I'll include some images of both our model & some inspirations on what we need for front suspension • Gear meshing – adjust centre-to-centre distances and tooth engagement to eliminate noise and premature wear. current gears work fine but I think due to our tolerances and PLA print. it just wears of quickly. we need to do it with metal gears. • we would also love to have metal version of our model once plastic version is fixed. need inputs on which parts can be made with metal for best reliability and longevity I can supply the current STL and physical samples. Once the updated STL, 2D drawings, and a tolerance stack-up are complete, I’ll need you to coordinate with me for 3-D printing to get a first sample produced, inspect it, and sign off that the achieved tolerances match the design. Deliverables 1. Revised 3D files and fully dimensioned drawings. 2. Tolerance analysis report showing before/after values. 3. Manufacturing liaison notes and inspection checklist. 4. A short hand-off call to walk me through the changes. If you’re within Hyderabad city limits, quick in-person visits will be a big plus. Let’s get this chassis dialled in so the car tracks straight every lap
