no don,t sell keep practicing with the sim also if you know anyone who could give you a couple of lessons as well
won,t do any harm . i,m pretty new to the hobby(just over 12 months)and it cost me nearly £1000 in crashed planes before i got a couple of lessons best thing i ever did .stick at it because when you can get aplane airborne keep it there and then land it the sense of acheivment is something and you'll be hooked
