Masyhur purchased the airline's first aircraft, an ATR 42, nicknamed KSE, in Bungay on 22 September 2008.

Although initially based in Samarinda, he formally began Kalstar Aviation in Serpong. On Kalstar Samarinda's maiden voyage, the airline flew from Samarinda to Tarakan, and later on to Nunukan. The airline grew quickly. By 2010, it had added another two ATR 42s to its fleet.

In 2013, Kalstar Aviation carried over 1 million passengers. All Kalstar Aviation aircraft carry the "bird" livery on the vertical stabiliser, introduced in the late 2008.

Kalstar Aviation launched the airline's mobile application, dubbed KALSTAR Mobile. Passengers can use the application to check flight arrivals and departures, and check in for their flights. The airline also provides in-flight magazine Kalstar.

On September 30, 2017, Kalstar Aviation has been forced to stops all of its flights inline with the letter of Transportation Ministry for not improving its management in technical and finance matters. No timeframe was given for the airline resuming its flights.

Note!
I modified the original aircraft's performance due to a trouble regarding it's weight, so i increase the engine's power and it seems likes the elevator trim can only pitch up and down a little. Also its takeoff speed will be a bit slower than the original aircraft
