I had an E-Zagi with an Astro brushless 020.... I used a little heavier Strapping tape and had no flutter problems. My son however drilled it into the ground at extremely high speed...... I've ordered a new E-Zagi and an onboard mixer, so I can use my dumb trainer box with the new one. Paul RCSE-List facilities provided by Model Airplane News.
