Completed

After eight weeks the Electric Banana is complete and ready for a maiden flight. AUW: 620 gr / 22 oz and powered by a 1300 Kv motor, 30A ESC, and a 3S LiPo/2,200 mAh battery. Wing span of 38 inches and a wing cubic-loading of 10.6. Power measurements with an 8x6 propeller showed a maximum full-throttle input power of approximately 140W. Assuming an efficiency of 80%, would yield about 110W maximum. According to my calculations this is more than sufficient for a basic 4 channel training and some aerobatics. Some pictures after an outdoor taxing test.

Wing and fuselage finish

Finally got my covering tools delivered. The covering iron was much easier to use then the household iron I tried before, and the hot-air gun was a huge surprise. I've never used hot air to stretch Monokote (or Monokote-like) covering, but the results I managed to achieve would not have been possible by simply using at iron. After completing both sides of the wing I decided to adorn it with some decorations. The bottom of the wing will get a checker box pattern in red, and the top of the wing will get a few red stripes to break the monotone yellow. I am using the Windex method to activate the glue and fix the red decorations to the yellow covering. I was told that I could do this only with original Monokote covering material, which is what I am using. So far, the Windex method works well, the liquid dries up, and the squares seem to be securely fixed. The fuselage finish has a natural balsa look with only a few coats of varnish. I am using Sanding Sealer for this instead of Dope, w
