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.
