Source measurement	Three initial design concepts were developed for the Model 45, including one with the Bonanza's signature V-tail , but the final design that emerged in 1948 incorporated conventional tail control surfaces for the benefit of the more conservative military (featuring a relatively large unswept vertical fin that would find its way onto the Travel Air twin-engine civil aircraft almost ten years later). The Bonanza's fuselage with four-passenger cabin was replaced with a narrower fuselage incorporating a two-seater tandem cockpit and bubble canopy , which provided greater visibility for the trainee pilot and flight instructor. Structurally, the Model 45 was much stronger than the Bonanza, being designed for +10 g and −4.5 g , while the Continental E-185 engine of 185 horsepower (hp) at takeoff (less than a third of the power of the T-6's engine) was the same as that fitted to contemporary Bonanzas.^[source]Beechcraft T-34 Mentor · Design and development; only the objects and conditions stated in this passage The Model 73 Jet Mentor shared many components with the piston-engined aircraft; major visual differences were the redesigned cockpit which was moved forward in the fuselage and the air intakes for the jet engine in the wing roots , supplying air to a single 920 lbf (4.1 kN) Continental J69 jet engine in the rear fuselage.^[source]Beechcraft T-34 Mentor · Design and development / Model 73 Jet Mentor; only the objects and conditions stated in this passage Equipped with hardpoints for training or light attack, able to carry 1,200 lb (540 kg) of weapons on four underwing pylons.

Thereafter, a range of improvements and alterations were progressively made upon the design as new models of the Rallye were introduced; typical advances included the adoption of more powerful engines, improved payload capability, and strengthened structure, the addition of wheel fairings, increased ground clearance for the propeller, expanded rudder and ailerons , and changes to the cockpit canopy arrangement.^[source]SOCATA Rallye family · Development; only the objects and conditions stated in this passage In the late 1960s, SOCATA pursued the development of an enlarged 7-seat version powered by a 300 hp (220 kW) Lycoming IO-540-K engine, the ST.60 Rallye 7.

Waco also sold the 150ST, 180CT and 235CT in the United States. However, the Rallye had little time to prove itself prior to Waco winding up its aviation activities following Berger's death in 1971.
