DXpert is a modular, micro fixed-wing maker platform weighing 50–150 g. It features an original airfoil optimized for high glide ratio and ultra-low-speed flight, enabling safe indoor and backyard operation. The airframe uses quick-release wings and tail with no pre-installed wiring, while a belly slide-rail system supports swappable payloads including FPV, VTOL, and airdrop modules. Control surfaces—ailerons, elevator, and rudder—operate as independent wireless nodes, coordinated via a unified mobile app alongside smartphone joysticks, IMU motion sensing, and professional RC transmitters. An AI flight diagnostics assistant guides tuning and modification. The platform serves RC hobbyists, makers, and families through a progressive unlock path from basic differential thrust to advanced aerobatics and autonomous programming, all on a single airframe.
