HeliSimRC Free RC helicopter flight simulator HeliSimRC is a freeware, Radio Control (RC) model helicopter simulator. It is designed to simulate the popular 450 size electric helicopters. HeliSimRC is intended to be used as a flight training tool, not a game. The design focus in writing this software was not on pretty graphics or a fancy look and feel. Instead, the emphasis is on authentic modeling of helicopter flight characteristics, and on offering features which enhance the flight training functionality of the software. in Radiostyrt > Helikoptrarwith helicopterradio-controlledrcsimulator
