Revmaster was founded in 1959 to rehabilitate VW automobile engines, and in 1968 they started to design conversions of these engines for aviation.

-The company was first located at Chino airport in California and finally at Hesperia, in the same state.

“Revmaster R-2100”

-Initially there were two models adapted, the 1831D that gave 65/72 HP and the Revmaster 2100 cc that gave 100 HP.

“Revmaster engine, special”

-The latest R-2100 version has what we understand to be a “low voltage” ignition, because together with each spark plug it has the high voltage coil with the shortest possible high-voltage cables.

-There is a total of 8 coils and in the photo we see two of them together under the rocker cover.
