Ditto on the sharp apc props. I was flying a foamy with himax 2025 gws 6.6:1 and apc 1238. At the time I still was not able to hover belly-in, and the new 1238 prop made the foamy torque so hard even full right aileron couldn't keep it from spinning. I gave it full down elevator and full throttle at the same time and flew it into my face. I ended up in the ER with my top eyelid sliced through right above the eyelash roots. Doc said if I had not shut my eye I might have lost sight in my left eye. To add to the misery, the doctor glued my eye shut while trying to glue my eyelid back together![&o] I had to tear my eye open with tweezers- talk about pain. I couldn't sue though because I work at the hospital and it was off-the-books backdoor treatment. Thats what I get for free medicine!
