Broke college student here, but trying to break into the hobby for a club. Looking at ali express, I see a lot of what appears to be clones of the SpeedyBee F405. https://www.aliexpress.us/item/3256806991272338.html?spm=a2g0o.productlist.main.10.856c749aFJgsLO&algo_pvid=081c9352-621f-4aba-991b-37dd6f54a400&algo_exp_id=081c9352-621f-4aba-991b-37dd6f54a400-9&pdp_ext_f={“order”%3A"13"%2C"eval"%3A"1"%2C"fromPage"%3A"search"}&pdp_npi=6%40dis!USD!38.28!26.80!!!38.28!26.80!%402101d6fe17629142584933644e7aea!12000039710524926!sea!US!6655004038!X!1!0!n_tag%3A-29911%3Bd%3A5c010a18%3Bm03_new_user%3A-29895&curPageLogUid=w3cImWrPjc9a&utparam-url=scene%3Asearch|query_from%3A|x_object_id%3A1005007177587090|_p_origin_prod%3A
I was wondering if these can use the existing firmware for the SpeedyBee, or if I would need to port it myself.
