Hobbyking's QRF-400 BIKE

Post by RTECH on Mon 22 Aug 2011 - 20:27





The QRF400 1:4th scale dirt bike is a big size R/C dirtbike
with plenty of power and quality components. The cast alloy rear
swingarm gives the bike almost 14mm of wheel travel, great for big air
jumps, triples, whoops or rough ground! Trick style, large
bore, upside-down front forks are designed to take big impact while
keeping the bike stable. The bike takes a 3,000 to 4,000mAh Lithium
Polymer pack and requires a 60A+ car esc.
Careful attention has been paid to drivability, the riders weight has
been lightened by 30% over other bikes of similar size, and the rear
wheel has a spider-gear gyro inside to balance the bike at slower
speeds.
This bike is capable of very high speed and with the rear
chain and sproket unguarded like a real motocross bike, we strongly
advise users to not allow children or pets near the bike while it is
running.


Spec.
Length: 530mm
Weight: 2349g
Motor: 540 Brushless 2100kv (REQUIRED)
Wheel Front: 160mm Moto-X Wheel Rear: 145mm Enduro
Steering Servo: Standard High-Torque (Included)
ESC: 60A+ Car ESC (100A Peak) (REQUIRED)

Contents.
QRF400 Moto-X Brushless Bike
Standard High-Torque Servo
Rider Figure
Decals
Pre Painted Shell

Required.
Motor: 540 Brushless 2100kv
3000~4000mAh Lipoly
60A ESC
Radio system (Tx/Rx)
50 meters of dirt, and quick reflexes!

These offroad bike have gyro in the rear wheel . That means even when the bike slow down, it will not fall easily because there is another turning wheel inside the the rear wheel.
This make controlling of the bike much more easier.
