How to optimize a plane? Remove everything that is not needed, like a long fuselage or the horizontal stabilizer, add some RC equipment, add a strong motor... and here you are: The LIDL Devil.
After having a hard trial and error phase to find the correct reflex setting and motor down thrust, the LIDL Devil is pure fun to fly. Its speed and climb rate are crazy and even slow flying is not an issue.
The only thing I still struggle with, is the launch (see outtakes).
For the onboard footage I used a RunCam Split 2 mounted on the wing (close to the fuselage). This had a very negative effect on the flight characteristics. Top speed was reduced by 30%, climb rate was significantly less and the reflex and trim setting used for flight without camera were completely wrong.
I would not recommend keeping the camera installed permantently, despite the great footage.
