Parkfun Fusion - First FPV test - Nokia 6120c

Yey, my first FPV test. Taped the Nokia 6120c on top of the plane at the COG.








The phone weighs 90g.












Flew well without any problems, so it's time to upgrade the camera to the next level!

Repaired and airborne

After using a whole dual tube of Expoy, I have fixed my Fusion and flew it this morning.

I originally crashed because I was stupidly performing dive/climb manoeuvres that made the wings bend far too much. The whole thing nearly fell apart in mid air. On my last dive, I couldn't pull up enough, so the plane ate dirt.






As you can see, I have added carbon strips to the wings to make them more rigid. They really made a great difference this morning.

Now it's time to test fly with 100g of weight on the front for training before I buy a camera and stick it on.

First test of brushless motor

Time for test flight now. If nothing goes wrong, I'll find a camera to stick on!
