DHK Optimus 4WD 1/8th Scale Brushless Monster Truck 2.4GHz

Nitro performance without the mess and noise, that's what the Optimus is all about! What's more, it's just about ready to run out of the box.

The high power, brushless, inrunner motor coupled to a durable 60A, fan-cooled ESC extracts maximum performance and fun from the included 3 cell 2600mAh Li-Po battery. Enough to give all but the most serious .21 nitro engine a run for it's money! Keeping the motor cool is handled by the fully-finned, CNC-machined motor mount. An optional fan is also available if you operate on really hot days.

But power isn't everything. You need to transmit that power into the ground and this is where the Optimus scores yet again. You have 4WD through 3 differentials, metal gears in the differentials and metal drive shafts. The front hub carriers are aluminium for low unsprung weight and durability. Needless to say, everything is fully ballraced for long life and minimum power loss. Grip is transmitted via full-dish wheels and mini-spike tyres. A tread pattern that works well on grass and dirt alike. The wheel style is both strong and practical. By shielding the hubs, dirt is kept away from the universal joints and bearings.

The anodised, T6 3mm aluminium chassis has all the screws recessed to limit damage to the heads and the side protection plates for the radio are moulded in tough plastic to resist knocks over and over. The top spine again uses anodised aluminium and creates a really strong structure to resist bending in jumps and rough off-road driving.

Suspension is courtesy of snazzy, anodised, 16mm, oil-filled, metal shocks plus anti-roll bars both front and rear. Camber and toe-in can be adjusted on the front and camber only on the back. Shocks mount on the tough, anodised, aluminium shock towers and have optional mounting positions top and bottom.

The aerodynamic rear spoiler is moulded in super-strong, flexible plastic to absorb those 'roll-overs' and come back for more. The same is true for the front bumper. Even the body has good impact resistance, thanks to the flexible, clear plastic chosen.

The radio is a fully computerised, 2.4GHz FHSS system. The transmitter has a full LCD display for programming. A really unusual standard feature for a car of this class. The steering servo offers 9Kg/cm of torque through metal gears and ballraces. Just about as tough as it comes!! Of course, there's a servo saver in the steering to absorb those unexpected shocks to the servo as well.

Included as standard is 240v AC, balance charger that can deliver 1A of charging. Again, a rare feature in a car at this price level. All you need extra are 8 AA size transmitter batteries. They can be Nimh re-chargeable or dry cell type. If you use Nimh cells, you will need to obtain a suitable charger for them.

With all this high spec. gear, you want style as well. The Optimus delivers! The body is modern and practical and the colour co-ordination extends from it to the metal parts of the chassis.

If you are looking for a serious 1/8th electric buggy, with serious performance and spec. but would rather not break the bank, the DHK Optimus is the only logical choice.

Please Note: If you have not used an RC car before we recommend that you familiarise yourself with the controls prior to use. We do not recommend the use of RC cars in confined spaces or domestic environments. Your model is covered by a manufacturer’s warranty; however this does not cover damage to parts, due to driver error or loss of control. Like its full size counterparts; an RC car has its own sacrificial parts which are designed to save additional components from damage. These inexpensive items are engineered to fail first and are commonly available. In simple terms, accidental damage is not covered by the warranty.
