RE: Starting Bench Safety Issues
After using a starting table for the first time 15 years ago, I would never even think about starting on the ground.
We also have 10 of the t-shaped tables at our club, I personally don't care for those either, as I find them to be to tall and I don't care for the wing restraints. They are riddled with prop strikes after only 2 years, apparently people have trouble removing there planes without hitting them.
I prefer the table below which we use at our other flying site, adjustable for all length planes and much shorter and less complicated than the stands shown above, made of scrap cedar from a deck project, this table is close to 20 years old and has been outside the entire time.
