FMS Flight Simulator Encoder
Practice without crashing your models
Published in issue 328, January 2004
We all know that even the best pilots spend many hours practising on flight simulators before taking to the real thing, so why should it be any different for radio control planes? With the FMS R/C Flight Encoder described here you can polish your flying skills and gain the valuable experience you need without having to invest in a radio control or even to build a model airplane. In fact the FMS encoder will even allow you to use your own radio control to further enhance your flying ability. Last year the author purchased a JR 4-channel radio control (R/C) and built his first electric powered plane. Unfortunately the maiden flight was a disaster so a more serious look at flight simulators was in order. Unfortunately, the cost of the so called professional simulators was too much to justify. Searching the Internet, a website called FMS was found.
