Redwing pretty much nailed it with his comments

I had a fighterbird last summer pretty similar to the firebirdxl.

I would go one step further and recommend that if you are seriously considering staying involved in this hobby that you GET RID of your firebird!!!

Here's why;

The firebirdxl and copies of it flew and react so differently then conventional (3-4 ch) models that learning how to fly one will not help you when it gets time to try your next model infact you will be at a disadvantage since you will have to UNLEARN some things.

Redwing recommends flying the model and using power to aid in turning he is correct. However on conventional models that are tirmed out it is possible to fly the model with the throtle in one spot. Also on mode 2 radios the throtle is on the left stick and the elevator is on the right stick when flying the firebird you use the wrong stick to control altitude.

I'm not bashing the firebirds... It's just that having experience with conventional glow powered and electric powered planes that I see the firebird as more of a toy that will quickly teach you bad habits and potentially turn you away from this hobby.

If your interested in a small electric plane (parkflyer/slowflyer) then I would suggest the GWS Tigermoth or picostick. These planes fly and react in a manner that is much closer to other models you may want to fly..

As allways getting some experienced help is worth more then you may imagine...
