JUST LIKE THE TEAM RUNS


Ideal from Club through to the highest competition racing Dragon IV engine 


– 3 port .21 size engine 


(pre broken-in with new 7.5mm carb and injector backplate) V2


The new Alpha engine, the Dragon IV, is a pre broken-in, 3 port engine designed to the


highest specification.


Very easy to tune and within 2-4 tanks, be ready to race.




New improved


Crankcase to improve the efficiency of intake and exhaust


Flow of fuel from the carburettor to the combustion chamber, and this results in less losses


and greater fuel efficiency, furthermore, an increase in engine power.


Ceramic bearings:


Reduced friction, lower weight, improved longevity.


The high quality material ceramic bearings are fitted as standard


to the Dragon IV, and with less drag, more energy can be applied to the wheels.


It’s reduced friction, lower weight for reducing the drag, and increasing


the engine power and the speed-up function.


DEC Crankshaft:


Reduced engine vibration, resist wear, good lubricity.


The new version of DEC Crankshaft, has the Alpha Patent – Dynamic Equilibrium,


which can efficiently balance the inertial force from piston pin, from conn-rod, and


from crankshaft rotation, to reduce the vibration of engine and to increase the engine power.


The timing on the crankshaft has been altered for more power and


a more linear power delivery has been achieved when combined with the new piston and liner.


Piston/Sleeve:


Redesign air intake can provide the fuel efficiency, more power and


a more linear power been delivered.


Piston Pin:


The piston pin improves the hardness surface and the durability in order to reduce the possibility


of bending, also made very light.


Cooling head:


The new cooling head adds one more layer, but has been lowered for improved centre of gravity


in order to handling of the car, whilst keeping good natural cooling effects when positioned in car.
