RE: ESM 74
Sawtooth: The sites suggested by Aghost are filled with tips and suggestions in the building and flying of this plane. I gained alot from the reads. I had Home Depot custom mix 4 oz jars of each ofthe 3 colors. The medium blue is spot on. I simply brought in two flap sections and they read the colors off of their spectrometer.Let me know if you need their formula.
