UltraFly Model Corporation is a Taiwan-based manufacturer of intermediate and advanced ARF electric R/C aircraft whose airframe parts are injection molded from EPS foam. They produce a line of brushless motors and brushless-compatible electronic speed controls as well. The products are distributed worldwide by Great Planes. UltraFly's goal was to determine the benchmarks of the size of the electric aircraft they would be competing against. They settled on 400-class park flyer aircraft with a retail price of US$85-100 ($95-110 European/Japanese).
