OOPS. Battery Fail

[yochanan]

Flying Sparky yesterday when battery got critically low, at 5ft altitude.
“Returning to Home in 10 seconds”. WHATTTTTTT?
In just three seconds, RTH took over and the battery failed before reaching the home point.

Now,……I know how to cancel it. Broken arm I think I can fix with JB Weld epoxy specifically for plastics.
Startup, camera and function of the motor appear all normal.

Wow! Sorry for your misfortune. Hope the jb weld works.

That's what happened to my Spark, up into the tree and back to the ground.

Gimbal is broke, replaced it, but now I have vision errors and the gimbal still doesn't work properly.

I'm going to tinker with the DJI Assistant and see if that fixes anything.

If that doesn't work, I guess it's back to the operating table.

The body of the Spark is available for purchase and there are YouTube videos showing how to transfer everything over if the J B Weld doesn't work.

There's some soldering involved at the motors if swapping frames.

Good luck with your repairs.

Yikes. You’re very organized and methodical. I hope it works.

Thanks. It looked very involved. Just my luck that if I did that, I will end up with error messages like many report.

In a couple of days I’ll put a reinforcing bead on it.

If you can find some fibreglass mesh, open weave, maybe give it a brush of JB over that (the repaired arm area), apply some strips of the mesh, brush over again, good reinforcement.
Hope it lasts for you.

 

[yochanan]

Not a bad idea.

Test flight 100% successful.
Hard to believe the electronics and sensitive camera gimbal could suffer an impact like that and not be killed.

They are a tough little drone, probably the toughest of the DJI drones.

Appreciating that fact, I bought a new one on Ebay from this guy as a back-up. Pleased with my purchase

Might be nice to figure out where the magnetic sensor is in the Spark. I know that if my Mavic Pro gets anywhere near any sort of metal, it messes up the magnetic compass. I've got lots of experience with JB Weld, and while it is absolutely the best, strongest epoxy, it has metal in it. This can be demonstrated by mixing up a batch, then putting a strong magnet near it. The JB Weld will travel toward the magnet! So I hope this does not affect your compass.

This isn’t regular JB Weld but a clear, plastic epoxy made only for plastics. Great info but I think I escaped that risk with this. I’ll try a ‘magnet test’.
