F6F Hellcat Profile Carrier
THIS model is the result of over five years of development through three sets of AMA rules for Profile Navy Carrier. It took first place at the 1979 Nats in Lincoln with an out-of-the-box stock engine, winning out over a large entry of skillful competitors, many of whom had expensive custom engines. The basic design has been built as a TBF Avenger and SNJ Texan as well as the F6F Hellcat by my friends and me. Minor changes to the fuselage outline and the shape of the tail and wing tips can change it into just about anything, as long as the moments and areas are retained. Although all these models resembled their prototypes, the earlier versions sometimes failed to receive ten scale points under the current rules.
Ni-Cd Battery Evaluator
ON A WEEKEND OUTING last year as I taxied my plane back to the pits after a flight, a friend said, "Look at your meter!" The meter on my transmitter read zero. I parked and pressed the battery test button. It was well into the red region. I have enough problems flying without dead batteries, so one rainy Saturday I decided to make a battery tester. A voltmeter alone tells little about state of charge and nothing about battery capacity (milliampere hours). It will identify a battery approaching the end of its discharge curve, however.
