Super capacitores, analise profunda
Com muita felicidade, a segunda parte do meu artigo sobre modelos outdoor com super capacitor foi publicado pela FFQ, edicao 78.
"Alexandre Cruz had presented a first article (Free Flight Quarterly #71, p. 8) where he introduced the possibility of flying high performance outdoor models with super capacitor energy source. Since then, the popularity of super capacitor models in free flight soared but mostly at noncompetitive or performance limited designs. This article brings a technical exploration over the power train commonly used for E20 models but having the Lipo battery replaced by a super-capacitor. This means direct drive 8.5mm coreless drone motors which are the largest high-performance brushed motors for drones, powered by super-capacitors in the 5F to 15F range, with output voltage from 3 to 6.6V.
The last part of the article concerns the application of the power train consisting of of super-capacitors and drone motors to small nostalgia power designs, in this article the Ron St.Jean Ramrod is scaled to E20 size, and its plan is presented at the end of the article. The powerful motor/super-capacitor combination endowed the model with a superb climb, encouraging the author to build other similar models, which he warmly recommends to the readers to try.
