Spark Jums up and down after take-off

[Willie Bornman]

Spark jumps up and down after take-off. How do I fix this problem. Straight after take-off the Spark starts to jump up and down. When the left stick is pushed forward, it gains height but not smooth. Intermitted climb motion.

Check to be sure the bottom sensors are clean and clear of obstructions.

My SPARK jumped up and down like a pogo stick after installing a strobe on the bottom. After removing it, the SPARK flew fine.

I think the intense flashing messed with the sensors.

You might try calibrating the IMU.

Pay attention to the position of the DJI logo on the tutorial as the steps are taken.

Good luck.

Thank you for your reply.
I did the IMU calibration several times without success.

I bought new propellers a few weeks ago via Amazon. I thought the supplier was DJI and used them for a few flights without any problems, then suddenly I had this jumpy drone.

After reading a ton of threads I decided to install a set of used original propellers. The problem is solved.
Old sparky is running smooth again. It was the 3rd party propellers after all. Now I sit with 12 new unusable props in my bag. Not the biggest problem in the world though.
