there is nothing wrong with the benches. Our club has about 8 of these. We have been using them for at least 5 years. They are great! Sounds like both accidents occured because we didn't use common sense. Never, ever stand inline with the propeller arc. If that prop breaks and you are inline you are going to get hit. What are the chances that it hits the bench and bounces up and hits the pilot? In the first incident, you should always walk behind the plane to remove the glow stick. In regards to taildraggers, I always hold up elevator when running up the engine to keep the tail down. I also grab the fuse from behind when running up the engine just to be sure. Common sense fella's, you can't buy it, you are born with it!
