My Deadcat SK450 is back running and as well as ever, the youtbe proof is above. The modifications I made:
- Replaced 3DR Pixhawk and GPS with Hobbyking Micro APM and no-name GPS.
- Removed 3DR power monitoring module.
- Used Spektrum DX6i radio and DX610 receiver.
- New landing gear shock absorbers (see picture).
The finished unit is shown below:
