The RTAF-2, officially designated B.ThO.2 (), is a single-engine training and liaison aircraft that was developed by the Royal Thai Air Force's Science and Weapon Systems Development Centre in 1957.
The RTAF-2 was developed from the Fuji LM-1 Nikko, itself a derivative of the Beechcraft Bonanza. One prototype was built in 1957 and tested in 1957âÂÂ58, although no further production followed.
By 1984 the sole example had been turned over to the Royal Thai Air Force Museum, Don Mueang District, Bangkok.
