Walkera Runner 250 Advance Upgrade
This documentation will be discussing how to upgrade Walkera Runner 250 advance to the MultiWii 2.4. This upgrade does not require any hardware modifications or disassembly. It can be done with the normal USB firmware upgrade procedure as describe by Walkera. You can also revert back to any old Walkera official version. I included to the MultiWII some modifications that will prevent the walkera flip of death. It will emulate the zero throttle air mode.
