I think 50%plane made the right comment at the outset. " I do NOT suggest a "cheap".... ".
747, what are you using the sim for? Your kids just to play with in passing, to actually learn certain realistic characteristics about model airplanes or Heli's?
Are you just looking to learn the basics to see if this controlled flight thing is for you or are you trying to learn certain techniques in your flying.

I could keep listing the questions but as was said before, do yourself a favor and spend the $$$. Around $200+. There is no substitute for the value of learning on a SIM at equal cost of your first plane with the unlimited savings per crash over and over again each time you try to learn something new.

If landing, torque rolls, recoveries 1 mistakes high etc. is relatively easy for a new flier..... the SIM may not being doing all that it should. You'll end up learning the reality though on your first, and forth and... real crash.

If you're serious about it, why waist the money on something that doesn't fully teach you basics and advanced stuff as you move along to transition to actually getting out there and flying. Plus with a good SIM you can still use it over the winter months if you can't get out and fly as much.

Don't get me wrong; OLD school, there was no such thing as SIMs for RC. So Ya! You can still learn on Cheap but the better the SIM and the more practice on manuevers, the better the pilot.

Choice is yours. Pay now or Pay later!
