I am both a private pilot and also flew RC for about 15 years. I would like to do so again.
About the real pilots not being able to fly the models, there are two or three thing at work there. As you know, real pilots use their feet for rudder, noit their left thumb. Also, when an RC is flying away from you there is little problem. When it turns around and starts flying back at you, the elevator is the same but aileron reverses, and that takes some getting used to.When you are inverted, elevator and rudder are reversed by aileron stays the same as when upright. Last, there is no "feel" for when the aircraft is about to stall ... that comes from experience.
Back in the bad old days, we tried to stay about 2-mistake height or higher. Today, with a trainer cord option, you can let the novice fly lower and closer in safety. Personally, I have trained maybe 10 people with a trainer cord and ALL learned much quicker than when we had to use just one transmitter.
Nice 109! I've never flown one, but have flown scale Fw 190's, a Thunderbolt, several Mustangs and one scale Spitfire. Mostly I prefer semi-scale since you can scale down the plane but you can't scale down the air. Semi-scale let's you use a slightly thicker-than-scale airfoil and retain good flying characteristics. Most actual scale planes I have flown had rather bad flying characteristics. I hope your flies well since it looks great!
Would love to try a scale Mosquito and would not care which mark was modeled. They all look good to me. Have seen one scale Sea Hornet fly (at an Arizona meet) and it was absolutely beautiful in flight.
Sorry for responding to the off-topic ... perhaps we should start an RC thread?
