The Avionic 3XG - 3 axis flight stabilisation controller not just works fantastic on you conventional planes plus also has added support for V-tail & Delta models.
Utilizing a single high precision 3-axis MEMS gyro, the Avionic 3 axis flight stabilisation controller is capable of stabilizing flight on just about any fixed wing aircraft! It provides added stability by automatically correcting the aileron, elevator and rudder channels in flight. This compensates for unwanted changes in the airplane's attitude due to wind and other factors. In short, it makes your airplane much more stable in flight! 
This is great for those who tend to fly in windy conditions, as it will compensate for wind gusts that would normally push your model around. It's also an ideal add-on to your favorite FPV model to keep it on the straight and level while flying.
This unit is very simple to install and use. The adjustable gain settings are pre-set to 50% offering mild stabilization. You can easily adjust the gain for each channel as desired to increase or decrease the compensation for the respective channel (AIL, ELE, RUD).
