PERFORMANCE

EQUIPMENT NEEDED (not included)

Inner Fenders
• The inner fenders are directly fixed to the frame to reduce flex and bend of the chassis and parts. They also avoid external objects entering into the chassis during the driving.

Front weight balance
• Weight balance of the GS02F chassis is leaning forward. This increases traction of the front wheels and provides better crawling performance at high angle hills or rocks. It also minimizes rolling over backwards when climbing.

Chassis Mounted Servo system

with panhard bar
• Steering servo in the GS02F chassis is located on the frame just as the real cars. Therefore the system eliminates bump steering effects which appear by the front wheel suspension movements. Additionally the panhard-bar is installed and cleverly designed to avoid any interference with nearby parts, so the front suspension and shocks can move freely.

Drivelines
• The drivelines to the front and rear axles are designed to arrange in a straight-line and this reduces fatigue or stress of the universal shafts and loss of power delivery.

Transmission
• Transmission of the GS02F chassis is designed to look as that of real vehicles. It also provides best performance for every driving situation.

Overdrive
• Overdrive system means the front and the rear wheels rotate for different speeds. The GS02F transmission is designed to rotate the front wheels faster than the rear wheels.

Better steering radius
• Vehicles with overdrive front wheels turn with shorter steering radius compared with non-overdrive vehicles. The overdrive also makes the control easier when the car is driving on rough surfaces.

Better climbing
• Increasing of the tire traction allows the vehicle to pass through steep slopes and obstacles without lifting the front of the body upward.

2-speed HI/LO transmission
• The 1st gear is for hardcore rock crawling and the 2nd gear is for hill climb or high-speed driving.

torque Twist Reduce transmission
• TTR(Torque Twist Reduce) transmission is designed to reduce unnecessary torque so the vehicle will drive with more stability. From the transmission, the front and rear universal shafts rotates clockwise and counterclockwise, and these opposite rotations compensate for rotational forces of action(torque) and reaction(reverse torque).

Dual slipper clutch

Dual slipper pads are designed to hold the spur gear evenly. Therefore the clutch allows more precise settings.

All metal internal gears

GA44 Axle
• The GA44 axle is designed for hard core rock crawlers in mind. This high endurance one piece axle is made of high strength materials and will look like real 1:1 scale vehicles’ when it is connected to 4 link suspensions. It is equipped with uniquely designed tilted differential covers and this design will help decrease damages of the differential covers and smoothly climb over the obstacles.

High steer knuckle arm
• High steer knuckle arm system increases the approach angle, so the vehicle can climb over the obstacles more easily than typical trucks.

adjustable CASTER
• The GA44 front axle has a caster angle adjustment system which allows users to choose a smoother and shorter turning radius or more straight running stability.

Metal diff locker

Hardened carbon steel CVA kit

Zero ackerman steering
• The GA44 axle is using Zero-ackerman steering system with CVA to ensure maximum performance with a short turn radius and smooth motion even on rough off-road terrain.

SD scaler shock absorber
• SD scale shock is a coil-over style shock absorber which is optimized for scale trucks. When driving, the oil inside the shock bodies will minimize the bouncing and high durability aluminum shock bodies and 3.5mm heavy duty shock shafts will ensure smooth driving on rough surfaces. Adjustable nuts will make it easy to change the ride-height of the vehicle so the user can quickly adapt settings to any driving conditions.

MT-1903 1.9 INCH M/T OFF-ROAD TIRE
• The MT 1903 off-road tires, made of super soft compound material provide much traction to the surfaces. The tread patterns are suitable for off-road driving and the large diameter of the tires enables it to run smoothly on any uneven road surfaces.
