ParkZone F-27 Stryker

The ParkZone F-27 Stryker is an electric-powered delta wing foam aircraft designed and distributed by ParkZone, a division of Horizon Hobby of Champaign, Illinois, USA, and sold in countless hobby shops throughout North America as a RTF (ready-to-fly) package.

This aircraft includes a 3-channel radio, with the three channels corresponding to controls for throttle, pitch, and roll axes. The signals for the elevators and ailerons are digitally mixed by the transmitter to control two control surfaces on the rear edge of the aircraft known as elevons, which combine the functions of the elevators and ailerons of traditional aircraft.

The Stryker has no landing gear, and is meant to be landed on soft surfaces such as grass.

The aircraft also has no rudder control. Its need for a rudder is minimized by the aircraft's lack of a landing gear, as there is no need to keep the aircraft perfectly straight while landing in a crosswind. In flight, turns are coordinated by pulling slightly back on the elevator control. When the stick is pulled back in a turn, the elevon on the inside of the turn continues to deflect the airflow while the deflection of the outside elevon is neutralized. Because the elevons are long enough to reach the wingtips, they can induce yaw on the aircraft to induce turns. This elevon yaw can also be used to enter intentional spins and recover from them.

Two models of the F-27 Stryker are currently in production. The original is the F-27B.

The F-27Q is slated for...
