I recently crashed my quad into a goal post and killed it but I can find and betaflight f3’s in stock and I’ve seen that there may be an f4 version? Does any one know where there is one in stock? or is there an alternative to this ?(currently the features that i use are the osd, current sensor ,voltage sensor ,the timer and the pdb but i dont strictly need that.)the features I need are the osd and the voltage as a minimum and easy to set up ;computer wise, I can solder reasonably well.
Thank you ,any help would be appreciated.
