RE: which trainer???
I did the same as you, i did not have enough money for gas, but gas is much better to learn on. If you want a fun plane, i suggest getting the slow stick. Its nice, and the reviews about it are endless +++. I started with the wattage cessna, trash. If you want to go electric, get a balsa made plane, it will fly better nad penetrate the wind. I remember my foam cessna coudlnt take on 4 mph winds and screwed up. The wood electrics are expesive at first, but get much cheaper. I suggest getting one set of gear, such as motor, radio, and a plane. I suggest seomthing like the goldberg trainer electric.
