it was windy all week and today i decided to fly any way and crashed.
flying outdoor is so much harder, and my only indoor spot is underground ASDA parking so its not high and lots of concrete post every 10m....

head is to badly damaged so i decided to get an complete head as in the original cnc head i broke hex screwdriver inside jesus nut and now i cant remove it without cuting it out :(

i started this hobby couple of weeks ago and so far is very unlucky for me... but its very addictive.

and hello to everyone in this forum :)
