Hi Just bought first plane yesterday, went with the cheap trainer to see If I can actually do this as a hobby (wanted to all my life).. .anyways I bought the tiger shark, put it together.. my problem is of course in flying, I have no crashed the plane, need new propellers and new cockpit door... but my question is

Both times it crashed it was becuase as it left my hand and climbed it turned left and I couldnt get it to run right to go straight... what is the reason for this? how do I control this?

any advice would be appreciated .
