apologies if this has been posed before - we are just beginning working our way into the subject matter.
We want to add both SW and (light) HW components to a multicopter for safety experimentation, in both indoor and outdoor applications. I’m looking for a reasonably robust commercial multicopter that allows me access to the PX4 SW running on it. It would be perfect if it has expansion ports - but we could work with just a circuit diagram would be OK.
Does anyone have any suggestions?
Thanks for any help. Best H.
