I recently purchased the new Commander 2 as my first plane and it's been great. After a couple of failed attempts in too much wind I had a great flight yesterday when it was nice and calm out. My only complaint is that it turns great to the right , very sharp. But itdoesn't turn left so good, it'll turn left but slow and wide. On the groung both sides of the taill seem to have the same amount of movement. Any ideas on how to remedy this? Thanks

Hmmm..... That's a bit of a head scratcher. You describe the right turn as "really sharp". My FBC will not turn right or left "really sharp", unless I give it some throttle. Is the left turn still poor under throttle? You don't state what mode you are flying in. I would suggest you use expert mode. Don't let it frighten you because you are a new flyer and don't see yourself as an "expert"- you will have more control.
Try: Put the plane in expert mode. Get plenty of height. Try a hard right turn on full throttle. OK? Level out. Now try a hard left turn, again on full throttle. It should be the same as the right turn. (Let go of the controlls when the plane has turned otherwise it will enter a spiral dive - this is why plenty of altitude is in order).
If your control surfaces were level at the pre-flight check with the battery connected and the TX on, and both control lines were tight with no slack, the plane should perform the same left or right. If it does not, contact Hobbyzone. They have a very good after sales customer service reputation and will replace a faulty plane.
Let us know how you get on.

Hi,
First, make sure the plane is straight, and not twisted or broke or bent from 'hard landings'
Veiw the v-tail from a ten foot distance from behind.... make sure the front (compared to the back) of the V-tail is pointed directly toward the front of the airplane.... If not, tug it over till it is straight.
Make sure the right rudder (the one that moves up when you give it left stick) does not have any slack in the control line. The line should be just tight. (this is the most likely cause). Tension the line a little (this should help!).
You could also move the control line down a hole (closer to the elevator) if this does not solve the problem.
Also, if the plane is flying too slow (trying to climb too steep), it will turn better to the right due to prop torque. You could gradually adjust the tail down (per manual) for a little less climbing, and more speed to improve the left response.
If none of this helps, provide a little more details based on CPF's notes above....
Hope this helps.
Have fun!

Thanks for the suggestions. I'll have to try it with the ACT off too. It's a little too windy today but I'll give it a go when it's calmer out and post back the results.

All of those suggestions are good, let me add one more. Make sure the wing is square on the plane. If the wing is offcenter one way or the other, then the plane will do exactly what you are describing. Sometimes in our haste to get the plane in the air, you won't notice the wing isn't on quite right. It would be nice if they put more accurate location points on the front and back of the wing. You can make your own by finding the exact center point of the wingspan and marking it with a permanent marker on the leading and trailing edge of the wing. I learned to fly on the Firebird line of planes and I still think they are the best beginner electrics out there.
