Maybe you’ve seen those hobbyists flying their rc airplanes, performing incredible aerobatics and thought you might like to get involved but be aware you are unlikely to succeed by just splashing out and spending your hard earned cash on the most impressive and advanced model in the shop.
Flying a radio controlled airplane and performing aerobatic stunts takes some practice and plenty of it. You may well be better off getting a cheaper smaller model to start with just to get a feel for how much concentration is really required to control a model airplane, then you can think about moving on to more complicated models.
