The new Optimus GP draws on that experience where important and is completely new where the demands of nitro power dictate. Fundamentaly, that means a whole new design of the main.
The durable, .21 class, rear-exhaust, pull-start engine is mounted longitudinally and transmits its power via an SG style crankshaft, aluminium, 3-shoe clutch and metal bell gear into the centre differential using a composite moulded main gear to absorb vibrations and reduce noise. Fuel is stored in the uniquely mounted, fast-fill tank that is designed to avoid the cracking that so many do in an impact.
The ergonomic, 2.4gHz radio system has its receiver in a water-resistant box and connects to a metal geared, ball-raced, 9Kg steering servo and a 3kg throttle/brake servo. A combination of power, precision and reliability that you would expect fromn DHK.
Fully metal, differential gearbox gears, fully metal shocks and shock towers are just part of the advanced specification that sets the Optimus GP apart from the competition.
