today I followed a friends advice not to dismantle the prototype but getting new internals to make a second version. As I didn´t had a ready device the last few months I couldn´t fly also. So the prototype 2 will have to proof itself in the coming days.
So the electronics will be below 200€ (excluding battery) if you order in my favourite chinese online shop Bangood.
I know this is not cheap but this tiny beast is comparable to a 5″ racer frame from the flight characteristics and the durability.
