My competition model is 98gms. I use a 500mAh single cell and a micro Airtronics receiver 3.5 gm servos. Contest balsa. Steve My latest Bug, #4, a Lightning Bug, weighs 110 grams, without too much effort to work on the weight. The pod is finished with 2 oz glass tape applied with CA and sprayed metallic blue with automotive lacquer. The canopy is finished with 1/2 oz glass cloth applied with CA and sprayed white with ACE appliance epoxy, retained with a tab and a magnet. The main ribs in the wing are reinforced with 0.12 mm x 1.5 mm carbon and the trailing edge is 0.7 – 0.5 mm x 3 mm trapezoidal trailing edge, both from A2Z. The wing is retained by a 1/8” carbon tube in the front and a 4-40 nylon screw in the rear. The tail surfaces are ‘skeletonized’ with the same carbon as the wing cap strips. The elevator is retained by two 2-56 nylon screws. Covering is Ultracote Lite transparent white. All of the tubes, wing spars and tail boom, are tapered, items left over from prior projects. The pushrods are 0.030” carbon rods in bondable Teflon tubes from Rick Walba, tailboom.com. The servos are Dymond D44s which are now, unfortunately, unobtanium. The receiver is a Spectrum AR 6300. The battery is a Kennedy 240 mah Smart Lipo. This winter I’m going to build one more Bug or Lightning Bug with a new airfoil and a bit of an effort to watch the weight, just to see if my prior Bugs can be improved upon.
