About this Plan

Quote: "An accurate scale model of the T-34 advanced military trainer still seen today on active duty. It is easy to fly yet stuntable. Beechcraft T-34 Mentor, by Bud Atkinson.

SCALE builders are always on the lookout for good scale subjects; ones that will adapt to model building and have good flying capabilities. Many times an airplane that is ideal for RC scale is overlooked. I think the T-34 has been, up to now, one of the overlooked. It's easy to build and has very good flying capabilities, much the same as our Class III stunt ship.

The Beechcraft model 45, named Mentor after the trusted servant of Greek mythology, first flew as a prototype in late 1948. Since that time the Mentor has served as a training airplane for thousands of United States Air Force and Navy pilots and continues in use at some military installations even today. Approximately 100 of the Wichita-built trainers are still in operation at the Pensacola Naval Air Station.

The Mentor was designed and privately financed by Beechcraft as a primary and basic trainer for the military services. It filled the design requirements so well, that over 1000 units were produced by Beechcraft for domestic and export sale. The aircraft was also produced under license from Beech by Japanese, Canadian and Argentine firms.

The Mentor, a single-engine, all-metal, two-place trainer, was built around the then-new Beechcraft Bonanza design to assure high performance while retaining economical operation and low fuel consumption.

The prototype aircraft was test flown December 2, 1948, by Vern Carstens, now retired, who was then Beechcraft's chief test pilot. The prototype Model 45 was powered by a Continental E-185 engine. It had a cruise speed of 160 mph at 10,000 feet and a top speed of 176 mph. Service ceiling was 18,000 feet and gross weight 2650 pounds.

The Mentor was stressed for ten positive and 4.5 negative G's and was fully aerobatic - a feature demonstrated in exhibitions at the Cleveland and Miami air races in 1949 and 1950 by the noted aerobatic pilot Beverly E Howard. Betty Skelton also flew demonstration flights in the early Mentor. Additional demonstrations were flown in the United States and overseas by Beechcraft and guest military pilots through 1949 and 1950, winning every evaluation competition entered.

First production model of the Mentor was delivered to the US Air Force, October 1953, at Edwards Air Force Base. There it underwent evaluation in training conditions similar to those it would en-counter in actual use. At one time during the evaluation, one Mentor was flown 23 hours and 20 minutes continuously with only seven brief ground stops for refueling and crew change.

A total of 1904 Mentors were manufactured by Beechcraft from December 1948 through 1958. These included 353 of the YT-34 and T-34 models produced from March 1950 to October 1, 1956 for the US Air Force. The US Navy version, the T-34B, was in production from October 1954 to mid 1957 with 423 units delivered. Beech also produced 318 units of the Model 45 for export.

Fuselage Construction: The T-34 fuselage is simple and straightforward, much like any stunt ship, and since it has slab sides and bottom, it makes for easy construction... "

    ScaleType: This (oz7726) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
