While the engines of our airplanes are on, it is impossible to see the
propeller from most angles because of the high RPMs. As you can see
this can be very dangerous and can even catch the best of us.
so, if you are ever doing anything with the engines:
- start them with the electric spinner or if its not charged then
flick it with a screw driver.
- Never flick it with your finger even tho this is a common way to
start engines among hobbiests.
- Never reach around the propeller. Instead move your body to the
other side of the testing stand.
Thanks for reading.
