Ryan ST

The Ryan STA was a low priced model I purchased from HobbyKing. It came with spring wing support rods that came off in the first flight. The CG is tricky but possible. If the battery is too far back, it will roller coaster, and if it's to forward, I was  not getting off the ground. When I lost the support springs and rods, the wings wobble and bend on bank and yank turns.

The Ryan STA does have some speed. I didn't want to go full throttle and turn too hard or the wing will give. I would have to say it's a good model for the low price I paid, but it could have come with a longer wing span.

The Ryan STs were a series of two seat, low-wing monoplane aircraft built by the Ryan Aeronautical Company. They were used as sport aircraft, as well as trainers by flying schools and the military of several countries.
In 1937 the ST-A Special was developed into a military version, the STM (also ST-M) series. Changes included wider cockpits to enable military pilots to enter and exit while wearing parachutes, and provision for a machine gun on some examples. Variants in the series included the STM-2P single-seat version armed with a machine gun delivered to Nationalist China; and the STM-S2, which could be fitted with landing gear or with EDO Model 1965 floats.

The first Ryan ST flew for the first time on 8 June 1934 and production began the following year, when nine aircraft were delivered. Except for 1937 (when 46 aircraft were built), production rates remained low for several years, at about one aircraft every two weeks. This changed in 1940 when deliveries to military forces began in earnest; production that year was just under three aircraft per week. Total production of civil and military aircraft prior to the entry of the United States into World War II amounted to 315.Another 1,253 military versions were produced in 1942 and 1943, for a total of 1,568 aircraft of all models. 
 Some U.S. Navy versions of the ST-3, the NR-1, were converted to specialized ground trainers to teach cadets how to taxi aircraft when on the ground or after landing, and especially in crosswinds. The main wing was clipped back to the landing gear; a small nose wheel added to prevent ground loops; a roll cage between cockpits to protect the pilot and cadet; and the throttle modified so the engine could not go over a certain RPM.
