So this one has me stumped.
These JJRC H31s are fun little quads. Not the ones I fly the most but they are sporty, pretty much indestructible and the price is right. Just the ticket when you’re not worried about camera/filming and just want to bash around.
Here’s the problem: I have 2-3 of these and the first couple work flawlessly. The last one I picked up will suddenly start doing flips and essentially dive right into the ground. The weird part is that is flies normally about 85 percent of the time so it’s not a total dud. Just very random out control movements.
Batteries are good, props are in correct place and good shape. It binds OK every time and I always do the standard calibration before every flight. Motors are good.
Opened it up and couldn’t see anything obvious on the board (antenna is OK & wires and solder joints look fine. I even switched transmitters to rule that out.
Maybe a bad board? Any suggestions or ideas?
