    I just want to let you know, no other build I’ve ever done has lasted as long as this one has flying around at The Underground parking garage(besides the 1S Pixel). Usually they last no more than a couple of trips but this one has been there like 10 times now and survived at least 8-10 good crashes into concrete. Given my track record that’s pretty amazing.
