Just yesterday I was able to make three last second recoveries from almost certain total loss crashes almost without thinking thanks ENTIRELY to training on RF. I can also do stall turns, inverted turns, inverted flight, immelmanns, Cuban 8's, crosswind taildragger take-offs, and slip landings after only 5 months of (very off and on) flying thanks to about 10 minutes a day of playing with RF in the evenings.
Tell your dad that REAL MEN use simulators!
