The Esky/Exceed Flight Simulator is a MUST HAVE ACCESSORY for anyone who has no plan to waste time and money to learn how to fly one of the most exciting toy in the world! Radio controlled helicopters are one of the hardest thing to master in the hobby-world and for anyone who is new to this hobby, expect to bust out your wallet to buy replacement parts because YOU WILL CRASH. However, with the RC Flight Simulator, it will definitely minimize your damage to the lowest and you will not regret because for all we know, this wise choice will cost you LESS than 20 bucks and the training is comparable to the same flight simulator that cost $300 from GreatPlanes and Horizon! With that big difference of price, you can just buy like 2-3 hot helicopters here!!!
