I soloed my last two students after their 4th lesson at the field. They both used the G2 Flight Sim before hand for about a month. One is my friend Piddler. He then went on to a Midwest Cjerokee 40, then the Hangar 9 Miss America P-51D Mustang. He is a Great R/C pilot and does very well. However, the "Key Factor" is not to ask more than the Aircraft can give and not over exceed your own limitations. I always tell folks to practice new maneuvers on the sim first, then proceed to the field, once the sim goes well every time. I have flown R/C for 15 years now and I use my G2 sim on a regular basis. I fly on line with others to simulate being at the field. I too fly full scale aircraft, but the two worlds are very different and yet very similar. I have found the most difficult R/C students are those who all ready have a pilots license. The easiest to teach are teens as they are so "Video Game" oriented with very fast reflexes. I advise when flying any type aircraft to keep the performed maneuvers to within the ability of the aircraft and don't exceed your own ability. This should keep anyone from taking home a bag of parts from the field.
