You said not to watch the video, so how could I/we comment on it?
Runs fine, but no wheelies? I wish we had snow so I could go drifting...
As for the Flextek issue = aw crap, not another company going down the pan. The arm doesnt look too baddly bent, may be able to straight it if you have a blow torch and anvil handy...
As for the future, I can only say to try another brand of arms & sell the Flexteks as spares (sure to make a pretty penny), or try not to crash
