Have hobbyzone firebird commander 2, new to flying. Could not get it off the ground, kept veering to right - and my friend's new, same plane, also did the same, yet veered to the left. Help
Some RTF aircraft are not quite RTF as they sometimes need trim adjustments. Also, a wing could be heavier on one side than the other as RTF models are mass produced with cheap and cheaply assembled components.
For a quick balance check, remove the prop and obtain an electrical terminal block (aka Chocolate block). You will need just the brass terminal insert with both screws.
Remove the prop and put the terminal onto the prop spindle. On the other open end of this, you need to insert a small curtain hook (ones that are used to hold up net curtain wires). Insert this into the other end. To the hook, tie a short length of nylon or cotton. Suspend the cotton from a platform such as a shelf. You need to be able to hang the aircraft without it touching the wall but it needs to be close to the wall. Once done, obtain a tape rule and measure the leading edge END of the wing. Move the tape to the other wing and make sure that the same position aligns with the same mark on the rule. If it doesn't, you need to add a minute amount of weight. About a gram, to the higher wing.
If it is fine, then remove the cotton and then tie a loop into it. Make another cotton string loop identical and hang it one plane length away. Using a small piece of sticky tape, tape the cotton to the tape and then to the extreme top of the tail fin. Loop the other cotton loop over the prop spindle, making in effect a cradle system. Again, use a tape rule to ensure that the both wings sit at exactly the same height. Add a piece of tape to the lighter wing to level it. A better way is to use nail varnish as it levels itself and prevents wing surface issues.
If both wings are okay, then it may be the tail fin rudder. It could be stuck on the right side rather than in the middle. This makes the aircraft fly to the right the faster the speed is, even taking off. Try trimming the rudder with the trim control on the transmitter or servo link.
If all else fails....buy a model boat as it could be the operator....
