The man who thinks he can.

If you think you are beaten, you are;
If you think you dare not, you don’t.
If you’d like to win, but think you can’t
It’s almost a cinch that you won’t
If you think you’ll lose, you’re lost,
For out in the world we find
Success begins with a fellow’s will;
It’s all in the state of mind.
If you think you’re outclassed, you are.
You’ve got to think high to rise.
You’ve got to be sure of yourself before
You can ever win a prize.
Life’s battles don’t always go
To the stronger or faster man;
But sooner or later the man who wins
Is the one who thinks he can.

Handy Factors For Common Calculations

Calculating Pitch Speed:
RPM X Pitch Inches x .0009469 = MPH Pitch Speed

Convert wing area from square decimeters (dm) to Square Inches and back:
Sq dm x 15.5 = Square Inches
Square Inch x .064516 = Square dm

Servo Torque:
KG CM x 13.887 = Inch Ounces
Inch Ounces x .072 = KG CM

Ounces & Grams:
Grams X .03527 = Ounces
Ounces X 28.3495 = Grams

Expanding Your Airfoil Knowledge

Erik Dahl Christensen’s Airfoil History
If like me, you love to design aircraft and want to get a better handle on airfoils, Eric Christensens’s site is an excellent study. Click his home link to find calculators and other sailplane design information. Even if your not into sailplanes, the information is clearly presented and it’s influenced my thinking and understanding of airfoils on many levels. Studying other aircraft disciplines will help with your discipline whatever it is. I found the Airfoils section of this site very interesting. In fact, I may go back and give it a read again soon. I’m saving the link here for that purpose and to share it with you. I am currently working on my first sailplane kit and this site has helped me a great deal. Get some glue on your fingers!
