What in your opinion is the best flight sim for under $50. I want to buy one but dont want to spend too much of the money that is being saved for a better heli. I have a Tactic TTX401 that came with my Axe EZ and If I could figure out how to hook it up I'd use one of the free sims for now but Im not sure it'll work. If not then I'll need a sim with a Tx.
