----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----I tried something neat last week:
I noticed that the back side of my prop was quite scratched up so I removed the old paint and gave it a new coat of black paint.
When the paint dried, I noticed I had painted it with the black paint that I bought for the dashboard. The surface was all rough.
Since I knew quite well that reducing the boudary layer on the back side of the prop would theoretically reduce drag and generate more lift on the shiny front side, I decided to test it before sraping it all off.
Static RPM seemed to be a little bit better, maybe just my immagination.
Slimb seemed definitely better.
I tried some special powered stalls and with tanks half full and only myself in the plane, I was climbing at over 500 FPM while advancing only 30 MPH.
No chance of a departure stall in a coupe.
Though my testing is far from scientific, the paint is staying on there.
After all, in THEORY it is supposed to work.
has anyone tried anything like this?
