Fi-115 is a toothpick-class FPV drone frame designed specifically for the DJI O4 Air Unit, providing a purpose-engineered mounting solution for DJI's O4 digital FPV transmission system in a 2.5-inch propeller micro drone form factor. The toothpick frame architecture prioritises minimum weight and maximum strength-to-weight ratio through a slender arm and thin-plate construction approach that reduces all-up weight to the lowest practical level for the 2.5-inch propeller class, directly extending hover time, improving agility, and reducing the kinetic energy of any impact during FPV freestyle and indoor proximity flying, where the micro drone format is most operationally relevant. The Fi-115 designation reflects the 115mm motor-to-motor diagonal wheelbase, positioning this frame in the compact micro class between sub-100mm whoop builds and full 3-inch toothpick configurations, with the 2.5-inch propeller diameter delivering the balance of thrust, efficiency, and physical compactness characteristic of this intermediate frame size.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe frame is specifically designed to accommodate the DJI O4 Air Unit mounting dimensions and antenna routing requirements, with dedicated mounting points and clearances for the O4 Air Unit camera, antenna, and main board positioned to maintain the structural integrity of the toothpick arm layout without the compromises required when adapting a non-O4-specific frame to DJI O4 hardware. This purpose-built O4 compatibility ensures clean antenna placement for optimal digital video link performance, correct camera angle adjustment range for the DJI O4 camera module, and secure O4 Air Unit retention in the crash-intensive operating environment of FPV freestyle and micro racing. The kit format includes the complete frame component set required for assembly, providing a weight-optimised, DJI O4-compatible 2.5-inch toothpick platform for pilots transitioning from analogue micro FPV builds to DJI O4 digital video on a compact, lightweight toothpick frame.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"AlfaRC","offers":[{"title":"Default Title","offer_id":67819230461995,"sku":"30461995","price":2549.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/FR-651__15493.1778743701.jpg?v=1791811427","url":"https:\/\/www.indianhobbycenter.com\/products\/fi-115-toothpick-frame-for-dji-o4-air-frame-kit-for-fpv-2-5-inch-propeller","provider":"Indian Hobby Center","version":"1.0","type":"link"}
