CoroWing SPAD

Last weekend at my flying club I joined in with the guys flying combat with their Unicorn Wings. I made it through the first round with just a lost winglet. Eight minutes into the second round, I pulled up into a loop in front of another wing and BAMM! The Unicorn Wing, which is made of EPP foam, went right through my BlueCor wing. For a $4.99 wing, it was worth it!

In rebuilding, I decided to use the CoroPlast corrugated plastic sheet I purchased on Canal Street. The wing is now a SPAD (Simple Plastic Airplane Design) and is indestructible. The wing still builds for under $5.00, sans electronics. You can find CoroPlast as low as $7.00USD for a 4′x8′ sheet, and you only need half a sheet.


I followed the same build guide and used a Kline-Folgeman airfoil. I did make a few changes, including:

  • Used all Coroplast.
  • Carbon fiber spar pushed through the flutes to increase stability.
  • Used 3/8″ square spruce instead of 1/4″ spruce. This increased the Kline-Folgeman step size.
  • Changed the propeller to a 9×4.5 from 8×6.
  • Increased the size of the Elevons for better response.

The CoroPlast is translucent and makes the wing look very modern and sleek.

    Can you please tell me what type of glue you use on your Coro Plast wings? Thanks
