This is how I make KFm2 airfoils for my RC planes' wings. I use 1/2 inch pink foamboard, I use this same thickness regardless of the wing chord, and put the step at half of the wing chord.

  • O make My airfoil with a angle of 60 degree and with no curve, does it still have lift?

  • @7h3unkn0wn That should be fine!

  • hey thanks for the awsome vid but do you think the pink foam would work as just a wing for a micro airplane im trying to build? because i dont have much weight to spare with the foam sheet

  • @zomnbvc Absolutely! Check out my RC Cargo Plane video and RC Scrap Delta Wing video, they both have wings made of pink foam and it works just great.

  • Chicagosrc says thanks for the info.

  • @chicagosrc Not a problem! Hope it helped!

  • @rockyFLYR Well, I made a 60 inch version of my Delta Wing and was testing it out. It flies great! The extra size carried 8000 mah of battery and a GoPro with ease. It had over 900 square inches of wing area. It was just a prototype but I didn't reinforce the wing enough and suddenly it started to vibrate/wobble (this was about its 10th test flight) and I lost all control of the plane and you can see the rest! I plan to rebuild! Perhaps a bit smaller this next time.

  • @letmeplaymystrat Thanks! Yeah, about that crash. Well, I made a 60 inch version of my Delta Wing and was testing it out. It flies great!
