Finally test flown my drone

After a few days off I managed to spend some time throwing the last bits on my airframe to get a test flight done. Would have happened earlier but I blew a 3.3vdc regulator on my apm board which I had to replace.  So far looking good just need to tidy up and then put the FPV on.See More

I got distraced and had to disconnect and come back and since then I haven't been able to connect to the unit. I have tried a windows computer too and…See More
