Sonerai Structure

The Sonerai I uses a minimum of different sizes of tubing to reduce the cost, without hampering

the integrity of the design.

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 wing is all aluminum and is composed of two panels that fold alongside the fuselage,

enabling the Sonerai I to be towed tail first on its own gear.

Stainless steel cherry rivets are used to skin the wing.

The Sonerai's wing spars are constructed from 2024-T3 .040" aircraft aluminum.

The ribs, ailerons and skins are all 2024-T3 .025" aircraft aluminum. The spars are built up using

strips of aircraft aluminum and riveted together.

The wings are installed to the fuselage using 6 easily removable taper pins.
