Technical Performance
The TYPHON MEGA 665 4x4 represents a significant step forward in 1/8 scale brushed RC buggy engineering. At 511mm long, 306mm wide, and 195mm tall, with a wheelbase of 328mm and overall weight of 2.92kg, this mid-motor four-wheel-drive machine delivers the power and capability that serious bashers demand. The high-speed MEGA 665 brushed motor produces substantially more output than competitive 550-size motors thanks to its larger 14-turn construction, supported by an aluminium heatsink and active 35mm cooling fan that ensures sustained performance during extended driving sessions without thermal throttling. The Spektrum SLT 2-in-1 40A waterproof ESC handles 2S LiPo batteries (maximum dimensions 165 x 51 x 48mm, minimum 5000mAh 30C rating) and manages power delivery through a responsive forward/brake/reverse drivetrain configuration. With a 15T pinion gear meshing against a 57-tooth spur gear, the 2.85:1 internal gear ratio delivers excellent acceleration whilst maintaining top speeds in excess of 20mph, making this one of the faster ready-to-run vehicles in its class. The independent all-terrain suspension with oil-filled coilover shocks and adjustable ride height absorbs significant impacts whilst maintaining predictable handling across mixed terrain. The dBoots 2-HO tyres mounted on tough 17mm hex multi-spoke wheels provide consistent traction whether you're running on dirt tracks, gravel surfaces, or short grass, whilst the sealed chassis with ventilation ports keeps internal components cool and protected from moisture ingress. Spektrum's SLT2 2.4GHz protocol ensures reliable communication at distance without frequency conflicts, and the S661 metal-gear servo's 125 oz-in torque rating guarantees responsive steering precision even during high-speed cornering.
