In the last few days I was going through my collection of props and was balancing all my 7" and 8" props for testing on my Fox .15x.
Thanks be to God that I noticed that the Master Airscrew 7 x 5.5 prop I had balanced IS AN ELECTRIC PROP!
I'm still a little spooked by the story of the recent incident of a wood prop exploding and causing great injury. I am being more conscious of getting behind and staying behind that spinning prop.
I almost missed that the MA 7 x 5.5 is for electric motors because the letters are tiny and hard to read AND unlike some props that visually just scream, "I'm really thin! Don't put me on an IC engine," the electric Master Airscrew props look nearly identical to their IC props (at least in these diameters) and (at least to me).
Needless to say, I'm taping highly visible notes on my Master Airscrew electric props and I'm going to double check that my electric props are kept separate from my IC props.
