I've built myself a hexacopter purchased from the martint (build your own drone) that has verygood service:)
I have spektrum dx8 as r/c controller
I have a strange problem, lives far north in Norway so here is Temperature around 0 degreesnowadays.
When I connect the battery to hexacopters outdoor sound engines of rapid beeps and will not start, indoors it works very well.
If I keep my finger on FDTI micro chip on the blue circuit board (APM 2560), the beeper graduallydisappeared. I have tried another blue circuit board and it's the same problem.
Some times 2 and 3 motors works, and the other beeps.
But I will not fly if the fault Temperature-dependent and come back in the air.
Anybody have any ideas about what can be?
