Overall the drone fly's well, very nimble and fast at the same time. But there are some areas that need some updating.\u003c\/p\u003e\n\u003cp\u003eSoftware : I would like to use Betaflight 4.5.1 the more enhanced GPS rescue options. It seems strange that a brand new drone would be on firmware from 2023 (4.4.3). The FC cannot be upgraded to 4.5.1 as of now because the tune cannot transfer correctly. I feel this is a serious issue to address for future compatibility and user appeal.\u003c\/p\u003e\n\u003cp\u003eHardware: The radio receiver module should be soldered to 4V5 pad by default to allow testing with USB connection instead of battery power. I also noticed there is no ESR capacitor for decoupling VBAT. There doesn't seem to be much room to add one. But this seems unorthodox for ESC designing and electrical circuit theory.\u003c\/p\u003e\n\u003cp\u003eSupport : The 3D prints are a great touch however the website STL files are out of date and they are not compatible with this 04 version. The Redfox A3 FC datasheet is also not carried on the website and I would prefer a PDF version than a paper copy.\u003c\/p\u003e\n\u003cp\u003eOverall the drone is very fast and fun with great flight times and stability. I plan to keep working on this drone to add upgrades and would love to keep in touch with SUB250 to provide more feedback and user experience.\u003c\/p\u003e","brand":"QiiFPV","offers":[{"title":"O4 Pro_PNP","offer_id":43318273638478,"sku":null,"price":439.99,"currency_code":"USD","in_stock":true},{"title":"O4 Pro_ELRS","offer_id":43318273671246,"sku":null,"price":449.99,"currency_code":"USD","in_stock":true},{"title":"O4 Pro_TBS","offer_id":43318273704014,"sku":null,"price":459.99,"currency_code":"USD","in_stock":true},{"title":"Without O4 Pro_PNP","offer_id":43318273736782,"sku":null,"price":179.99,"currency_code":"USD","in_stock":true},{"title":"Without O4 Pro_ELRS","offer_id":43318273769550,"sku":null,"price":189.99,"currency_code":"USD","in_stock":true},{"title":"Without O4 Pro_TBS","offer_id":43318273802318,"sku":null,"price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/4191\/7774\/files\/imgi_130_1_Main_0000_1aa7833f-2606-4369-b6fc-05e96cdc2f9a.jpg?v=1768293863"}],"url":"https:\/\/www.qiifpv.com\/collections\/250g-fpv-drones.oembed","provider":"QiiFPV","version":"1.0","type":"link"}
