Sims
I purchased the RF G2 recently, and am very impressed with the graphics and realism of flight characteristics. I have not flown RC for well over 20 years, and the simulator, I know, will save me $ in the long run. (I recently re-entered it)
I also think that being able to change the pilot's view of the aircraft, provides, especially a newbie, with a visual link how the plane really reacts to stick inputs ....without squinting! (Oh, I guess if I do that the tail slides left..wow...Yaw?...).
I think you get the picture.
Practicing coordinater R/A turns, landings, circling...etc. You can get the ops to do it all, and take some the first time apprehension out flying.
Well worth the investment IMHO JB
