It's was already doomed with that guy trowing.
this reminds me of myself some 10 years ago, when I took my electric powered RC Me109 with 1m wingspan for a first run. Wind was so strong, yet I was so stubborn. Two times launch ended like the one above, 3rd was a charm, it went almost straight up to 15m, and then plummeted like a kamikaze. Found the motor 10m from the rest of the wreckage, even the rotor shaft got bent!!!
Rüdiger !!!!nicht in den Boden !!
