First flight - derbe evo

Image
The copter had its first flight yesterday. With the 5.5" Graupner Race-Props, the speed is absolutely amazing - I still need to learn how to control such a fast device properly.

Here is a quick + dirty video:

And Shrediquette is still open source of course, so here are the 3D files:

The arms are from the Claerials HUMs quadrotor: http://claerials.com/shop/hums-ersatzarm/






Shrediquette derbe evo: Finished, first flight this weekend (if it's not raining constantly...)

The derbe evo is ready, I just need to find a suitable antenna...

Some images of the assembly process...:




There is not much space inside the frame, but everything fits. The assembly also went quicker than I thought. I just need to replace all the motor shafts of the Graupner Ultra 2806 2300 kV motors (due to a hard crash), and then I am ready to go.

The take-off weight is just 447 grams.

I think I now have all the parts that I need to start assembly. The frame weight is 77 grams (without electronics).

Here is the latest teaser:
