g-day mate
i taught myself to fly
i am 16 and started when i was about 10 building and flying bulsa flat wing gliders very simple but they gave me a realy good idea as to how a plane flies , trimming , COG ect ect
when i was 12 i got my first rc plane a very small electric twin engine thing called the {SDM Dragonfly} which is controled by diferent prop speeds on each wing
then i got a 3 channel J3 cub electric still then i took that out and taught myself to fly that one and then i got the Parkzone Typhoon 3D and lurnt to fly that with a small amout of help on my first flight from a guy i met down the park and about 3 years later i got another small 3D plane then a parksone F27-c stryker and then about 6 years from the start i now have me a 60 size katana 3D which i have flown twice and have no troble with it 
so im saying it is possible but it is hard and takes a longgg time and a few extra $$$
sims are awesome for lurning get one
if you can get help
good luck  and happy  flying
