The Sonerai I is a mid-wing sport plane, racer, designed to meet all Professional Race Pilots Association (PRPA) and Formula Vee Racing requirements for 1600cc Volkswagen powered aircraft. The Sonerai I will accept engine displacements from 1600cc through 2180cc.
The Sonerai I uses a minimum of different sizes of tubing to reduce the cost, without hampering the integrity of the design. The wing is all aluminum and is composed of two panels that fold along side the fuselage, enabling the Sonerai I to be towed tail first on it's own gear.
Stainless steel cherry rivets are used to skin the wing. The fuselage and tail surfaces are constructed of standard sizes of 4130 steel tubing that are fabric covered. All aluminum sheet used is 2024-T3 .025" except for the spars which are .040". The fiberglass cowling removes easily to allow complete access to the engine, magneto, tank and instruments. The landing gear is manufactured from 1/2" x 5" 2024T-351 aluminum. The Sonerai I features an 11 gallon tank.

The Sonerai's fuel system will handle both auto fuel and aviation fuel. If auto fuel is used a fuel pump must be used to pressurize the fuel delivery system to the carburetor. The engine's compression ratio must also be matched to the octane of the fuel being used.
