TNCA Microplano

In February 1918, the Talleres Nacionales de Construcciones Aeronauticas (TNCA), or National Aircraft Manufacturing Workshops, at Balbuena Airfield, Mexico City, completed the prototype of a single-seat fighting scout to the designs of Francisco Santarini and Capt Guillermo Villasana. A single-bay unstaggered biplane known as the Microplano, the aircraft was powered by a 180hp Hispano-Suiza eight-cylinder Vee-type water-cooled engine driving a Mexican Anahuac propeller, and was of metal construction. The intended armament was either one or two synchronised machine guns. Although flight trials of the Microplano were allegedly satisfactory, no series production was undertaken owing to the overthrow of the Carranza regime and the ensuing civil war.

Aesthetically it seems to owe much to the contemporary Italian fighters. It's possible, because in those years the Mexico government bought a small amount of Ansaldo A.1 "Balilla", and maybe its observers tried or saw other similar aircrafts.
But it's an opinion for which I've no evidence to bring.

señores Manuel C y Cesar Rosales: Después del primer vuelo de puebas, al Serie C se le hicieron importantes modificaciones en las superficies del empenaje, se incrementó en área alar en el plano superior y se incluyeros alerones (solamente en ala superior). el timón de área circular y elevadores flotantes conocidos por la clásica foto de perfil del Serie C resultaron muy inestables. Me interesaría construir un serie C modificado como se muestra en la foto de "la velada fúnebre" del 3 nov.1920 mostrada en la página del "MEXICANAVIATIONHISTORY". estoy trabajando en el plano de tres vistas de esa modificación. Saludos al Sr. Carlos de la Lanza de Monterrey... Excelente ejemplo de rescate de los modelos del TNCA.

Hi Nikolai! They did not move to the US as they wanted this plane to be Mexican, that's why. I'm sorry to say i found (at a flea market in Mexico City), bought and kept for years a large 1 /4 scale industrial, preproduction test model of another mexican airplane (circa 1910)including metal machined parts and FULLY OPERATING controls and landing gear, but at one time (I was young, divorcing and the plane was HUGE)SOLD IT! I now hate I did!

Why didn't they move to the USA?
They could comlete their project there.

Thanks for share the Mexican historic airplanes, some part of history said the fact that the Microplano Veloz achieved the no oficial speed record in 1920, here a simple free flight plan: /tectonite /iWeb /Site%205 /Mooney_files /Microplano-Veloz-1.jpg
