dang geek glad u ok.i got a few cuts before trying to flip a sharp prop but nuthing serious as urs.i find it not to easy and pretty dangerous when i am adjusting my eng.cause u gotta run it full throttle to find peak and the usually preflight checks.thinking seriously bought getting a tie down system like a wooden stake and rope and maybe u should to.cause i got fear for a full or idle spining prop.heard bout one guy that the impeller was spinning and it ran all the way up his arm just cutting away.lucky the poor guy didnt bleed to death.take care geek and just think it could have been much worse.
