UFRC Big Bully GR1 4WD 15 Brushless Buggy 12S, RTR Version, painted body shell

UFRC Big Bully GR1 4WD 1:5 Brushless Buggy 12S, RTR Version, with painted body shell. Big Bully GR1 - the new 4WD metal model from UFRC incl. TT56112/520Top Tuning Monster Brushless Motor 520kV.

Y1549 ZTW Beast Pro 300A 12S ESC. SPM5120 Spektrum DX5C Smart 5CH DSMR radio control incl. 2 pieces y1570 CYS S0650 large scale servo, 55 kg/0,11 sec for Steering.

2 pieces y2009 Top Tuning Digital pro Servo 25 kg for Differential lock. 2 pieces of 4S batteries with EC8 connectors total max.

Size for both batteries combined: length 193 mm × width 125 mm × height 100 mm. Besides its excellent workmanship, there are many special details that clearly distinguish it from other vehicles on the market. Its external dimensions are not much bigger than those of a 1/6 car, yet its wheelbase is on par with many 1/5 cars and it has no overhangs at all; its tires fit a monster truck 230 mm diameter! This results in amazing handiness for a large scale car combined with outstanding off-road capability. The GR1 comes out of the box almost as an all-metal vehicle.

Tuning parts to reinforce the model are no longer necessary. Center and rear differential come standard with mechanical locks which can be activated independently by the radio. Of course, a radio system with the appropriate number of channels is required to use this feature.

The dimensioning of all parts is designed for great reliability, e. The ball joints in the lower trailing arms are standardized industrial swivel bearings with an inner diameter of 6 mm, and the driveline can handle 12S hands down. But according to our experience, 12S operation is simply unnecessary. Nevertheless, we offer 12S equipment in the options menu.

Oversized drive shafts also on the front axle are machined and hardened steel with fixed joints at both ends and sliding piece for length compensation. The tires feature a vulcanized fabric reinforcement made of Kevlar; ballooning is actually a thing of the past for them. Thanks to Kevlar, the fabric belt can be relatively thin, so the tires are soft and flexible despite the fabric. Aluminum servo arms for all 4 servos (steering and differential locks) are standard. The levers of the two steering servos are adjustable.

Each steering servo has its own adjustable servo saver. A stainless steel adjustment tool is included. The Ackerman rod features four ball bearings. Shock absorbers with 8 mm piston rods and hard anodized shock bodies.

All drive gears milled from steel and hardened. Two voltmeters can be optionally installed in the receiver box to monitor the traction batteries. The cage can be removed with only 4 clips, but even that is not a requirement for battery replacement. Inclusive original FG Monster Buggy body shell with rear wing. Big Bully GR1 (1/5 4WD solid rear axle). Main features of the 4WD Big Bully GR1. The strength of the components supports 12S power.

The wheelbase of 1/5 scale cars: 565mm. The length of 1/6 scale cars: total length 790mm (when equipped with wheels with a diameter of 230mm).

The weight of the GR1 ready to run with 2x 4S/10.000 mAh batteries and 700KV motor is about 22 kg. But if you think now that this is a ponderous steamroller, you better think again. A "Tank on speed" is a better description. Despite the weight, wheelies can be called up at any time thanks to the appropriate gear reduction, even if the controller is only set to level two of four in acceleration (punch). At the same time, the possible twisting of the chassis is almost like that of a crawler. With the diff locks activated, the GR1 is almost unstoppable.
