Flying toy quads are fun but they aren't much help when it comes to flying in acro mode. The Eachine H8 quadcopter runs an open source firmware which can be updated. Firmware provided by silverxxx from rcgroups has the ability to fly in level mode or an acro mode. Big thanks to him!
The hardest part of this project was finding which software to download. There were a lot of choices and the right one wasn't always well documented. Hopefully this video helps!
The overall upgrade process is not too difficult and the end result leaves you with a toy quad that can fly in acro mode for less than $20!
