This is the SpitfireMKV with aileron gyro. It is a nice flyer. There is also a version without gyro if you want a more realistic feel.

4 .303 Browning Machine Guns and 4 Hispano Cannons: Down on Channel 5 (Dual Rates)

Features Retractable Landing Gear: Channel 7

It has springy scale landing gear.

The machine guns and cannons fire at slightly different times to make them look more realistic.

Enjoy!
