The stock transmitter that comes with the Eachine E010 is awful, very hard to control the sticks. Here is my handle extension, which hugely improve control and comfort.
There are two different height of the extension: 15mm and 20mm, choose one of them. I would say 15mm is for thumbers, 20mm is for pinchers. I personally prefer 20mm as control is more precise.
Usage
1. Print 2 of them for each stick
2. Use a zip tie to hold them together
Here is my tutorial how to turn the Eachine E010 into a Tiny Whoop:
