Eachine Reddevil Review PID Betaflight 4.0.5



Eachine RedDevil 105mm 2-3S FPV Racing Drone with Crazybee F4 PRO, Caddx EOS2 camera, 5.8GHz 25~200mW Nano Video transmitter
Banggood Coupon: BGWKRED or Drones6
http://bit.ly/ReDevi

RedDevil is like Sailfly-X but with better Caddx EOS2 camera and powerful VTX 25-200mW. From the weight equal to 37 grams which guarantees a lot of fun.


Pro:
- VTX 25-200mW
- EOS2 camera
- F4 AIO board 2S-3S
- support all receiver

Cont:
- bad PID BF configuration
– camera canopy is wobble
– video antenna is too loose

My fixes:
1. add two cable tie to the camera canopy to resolve the video vibrations
2. add a cable tie to the video antenna to protect it
3. use textile adhesive tape to protect the motor cable
4. cut out the battery foam , so that the foam no longer presses on the front connector
5. replace the EOS2 camera with a Runcam Nano 2 if you have a FPV goggles with 4:3 aspect ratio
6. install Beta 4.0.5 with my Betaflight DIFF and the PID setting from Albert Kim SailFly-X

My configuration with FrSky Crazybee-F4 board. The PID's are from SailFly-X to fly 3S Lipo with Rate1 profile and for 2S Lipo with Rate 2 profile. PID's setting are from Albert Kim Betaflight 4.0 PID Tune for Sailfly-X
I have installed Betaflight 4.0.5 to the Reddevil with this changes:
