IamA woman remote control airplane pilot who has won 6 national titles. I fly large scale airplanes (40% scale with a 150cc engine). AMA!
I have been flying RC airplanes competitively for 8 years now. I was initially surprised to see that there are very few girls involved in this hobby (I have met about 5 out of over eight years of involvement to give you an idea). That's the only reason I mention my gender, because the girl/RC combination is definitely 'uncommon' and sometimes people have questions specifically about that point of view. Edit: I don't think it's special in any way other than being kind of rare. At the peak of my involvement I would practice several hours almost every day. This allowed me to win all 6 categories of the Canadian National Scale Aerobatics championships over a period of 6 years. I love the hobby. I am also involved in RC helicopters, gliders, and cars.
Edit: I think it might help if I describe in a bit more detail the type of competition I'm involved in. It's called scale aerobatics (IMAC is the most widespread version). You get a series of 10 aerobatic maneuvers which are similar to what real aerobatic airplanes would do in competitions. You have to fly them as precisely as possible (there are specific deductions, like you lose 1 point for every 10 degrees deviation from what a line is supposed to be in the figure). It's the same 10 maneuvers all year, except for one round on the second day of the contest, which is called the 'unknown' round. You get a list of 10 surprise maneuvers the day before and overnight, you memorize them and visualize them and do whatever mental exercise you can to try to prepare to fly them, but you're not allowed to actually use a plane or simulator and practice them. The next day, you fly them for the judges and the first time you fly them, you get evaluated. There is also a separate event called 'freestyle', in which you choose a music or mix of musics and design your own routine (4 minutes length). For the freestyle, you get judged on technical and artistic criteria.
