The Taiwanese brand Argus have introduced a new nitro engine for GT cars available in two versions: the 21-GT and the 21-GT Evo engine. ARGUS team spent plenty of time designing this new engine for 1/8 scale GT racing (a class that is becoming popular nowadays). The 21-GT provides strong torque to move the heavy GT vehicles around while still delivering power and high RPM performance. The cooling head features a stable and predictable heat transferring and low gravity.
The power plant uses a 3-port sleeve producing a liner power and a low fuel consumption. The three needle carburetor is more precise and easy to tune.
The 21-GT Evo version shares the same main features but brings some improvements. There is a dynamic equilibrium crankshaft (to assure smooth and improved acceleration), front and back high speed ceramic ball bearing (to reduce the resistance of rotating mass) and a new crankcase covered with heat sinks with black color which has the better cooling efficiency and to reduce weight.
