Many times I get asked… is there a way to remove the altitude restrictions?
To be very honest.. I don’t want you to, only because there are rules that we should respect.
But then again, why should your drone be restricted?
So the answer is Yes, you can! and you can do it on the H501S H501A and H501C
I have found a way to remove this restriction, and your maximum height is based on the range of your signal.
This is a mod I have not designed myself, nor did I make the video.

This mod is only tested in firmware versions: 1.1.11, 1.1.17, 1.1.21, 1.1.22, 1.2.3 and 1.2.6
It might work on other versions, but that is up to you to test, and if it works let me know!
All the tested firmware and required tools can be downloaded right here: Download firmware needed
Once you have all the software it is time to mod the firmware.
Have a look at this video, it is VERY easy to do!
By setting the max altitude string to 0 you remove the limitation.
Please do not change any other setting, this could mess up your drone and you might even crash it!
Be advised that this might harm your warranty with Hubsan, and you certainly are breaking rules in most, not all countries. Fly responsible!
