When using a prop for pusher must put in backward to keep the attack edge
Any way I'm sure you read more than I do.
I must say I am with Crist on this one.... for a moment it looked like he was right and one of the pictures looked like the prop is installed the wrong way...
even looking at the pictures two posts ago they all look wrong.
Either the pictures return a false perspective or someone is well confused with propeller orientation.
a propeller has a concave side and a convex side. The convex side should alway point towards the front of the plane . I would not trust on the writing although the writing is generally on the convex side.
Now... here we are trying to help each other and I think some smart comments are uncalled for.
All of us write in here in good faith. This is a genuine case and believe it or not, this is a very common mistake .
A propeller mounted backwards will be so inefficient that the plane will feel underpowered despite the motor burning the right amount of power.
