Serious nitro, competition performance without the mess and noise, that's what the Optimus XL is all about! What's more, it's just about ready to run out of the box. All you need to add is a charger and some AA batteries for the transmitter.

The Optimus XL is performance bread and is not for the feint hearted.

The high power, brushless, in-runner motor coupled to a durable 100A, fan-cooled ESC extracting maximum performance and fun from the included twin 2S cell 2300mAh Li-Po battery setup. Enough to give many nitro engine a run for their money. The motor is kept cool by a finned, CNC machined mount that you can fit an optional fan to if required.

But power isn't everything. You need to transmit that power into the ground and this is where the Optimus XLcomes into its own. 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 ball-raced for long life and minimum power loss. Grip is transmitted via large, tough wheels and chunky tread pattern.

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.

Beware! This buggy is seriously fast and can cover ground much faster than you may think. You will need to hone your driving skills to master the Optimus XL!
