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.
New improved
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:
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:
a more linear power been delivered.
Piston Pin:
of bending, also made very light.
Cooling head:
in order to handling of the car, whilst keeping good natural cooling effects when positioned in car.
