I assume you’ve seen my video on Youtube (if not, scroll down) and want to make your grasshopper do the same. In short, you can achieve this by just updating 2 (or 5 to be more exact) components’ firmware. Lets head to the Ideafly Grasshopper upgrade right away:

Ideafly Grasshopper upgrade

Lets understand whats going to happen:

First of, we are going to replace the flight controller’s firmware, from Cleanflight, to Betaflight. Betaflight, for those of you who are new to drones, is a more advance version of cleanflight. It starts with BETA because it is a beta version of cleanflight. BUT, beta doesn’t mean it is not stable.

Second, we will upgrade the ESCs firmware, from Blheli to Multishot. Multishot is a newer, and faster, ESC protocol.

Lets start!

Disclaimer,

If you break your drone, brick your ESCs or flight controller and etc, it’s your problem 🙂 It’s not a simple process and if you’re don’t know what you are doing, it’s probably not for you. Come back when you know what you are doing. thank you.
