What exists
- RC-3D-CAR — COMPLETE: 1/10-scale Arduino-controlled RC touring car in FreeCAD 1.1; 52 in assembly, 28 unique parts + 2 utilities; chassis, steering, suspension, drivetrain, body, lights — STL/STEP exported, print-ready
- RC Bluetooth Smart Car — in progress (2026-07-19): ESP32 Classic Bluetooth SPP + Flutter Android HUD (dual joystick); L9110S H-bridge; link failsafe (stop if no command in 400 ms); firmware/app/SPP proven; motor Dupont wiring unreliable; compact PCB v0.2 is the product path
- agri-drone — NEW scaffold: design pack for agricultural quad-X: hub, arms, motor mounts, landing gear, spray tank cradle; macros and parts not started
- esp8266-firmware — dual-target ESP8266/ESP32; flashed and verified on ESP32

Status
RC-3D-CAR Complete; Bluetooth car In progress; agri-drone Scaffold
RC-3D-CAR is complete. The Bluetooth RC car is in progress. The agricultural drone pack is a design scaffold — not a flying product.
