A strong chassis andsmartlayoutis important foranyracingmaching, and it's no different with 1/8 scale rallycross buggies. The Pulse,withitshigh performance design, takes in all the latest racing refinements from the fastest buggies on the track and combines them in a fast and durable package! Check out the top features of the chassis and layout:
  • 3mm chassis made from 6061 gunmetal anodized aluminium, deep countersunk screws and sturdy dirt guards
  • 6061 aluminium radio tray, middle deck, and front deck for light weight and great looks
  • Composite chasis braces connect to radio tray to reduce weight and eliminate flex from the suspension
  • Hex hardware throughout for easy rebuilds and less hassle than normal Philips head screws
  • Low centre of gravity design for increased confidence in the bumps and better handling in the turns
  • Large flywheel opening allows rocks to exit chassis and extra-easy starting with any off-road type starter box
  • Sealed & padded battery & receiver box with sealed radio switch

A strong suspension design that is easy to adjust and control is key to a good racing machine, no matter what size it is or what type of racing you're doing. Our designers looked at all the top-performing cars out there and combined the best suspension designs into one ultra-competitive package. The Pulse gives you full adjustability: anti-dive, anti-squat, camber, caster, droop, Ackerman, roll centre, camber link position, shock position and wheelbase.
  • Proven race geometry with championship-inspired design. The zero kingpin 'inverse angle block' design is a definite winner, and out on the track it will give you the confidence you desire as you go head to head against the club pros!
  • Extra-strong race-engineered suspension arms are designed with the optimal balance of strength and flex to tackle the most demanding racing tracks and racing drivers!
  • The front shock tower is 7075 aluminium for extra durability and increased reliability. The rear shock tower is 6061 aluminium, anodized the same cool gunmetal grey.
  • 15mm dia large bore shocks handle the bumps and jumps, soaking up everything you throw the Pulse at. With a 6061 aluminium body, o-ring seals and thick shock shafts you know your tyres will be stuck to the ground when you need traction and control.
  • Strong steel turnbuckles with chunky gripping points for easy adjustment of camber and front toe.
  • Extreme steering angle for tons of steering - there's no other buggy with as much steering angle!
  • Extra-strong 6061 aluminium steering link with 3 adjustment holes gives you confidence that you won't lose control, and the extra adjustments let you fine-tune the Pulse buggy to your driving style.
  • You also get an integrated servo saver with an easy to reach knurled aluminium adjustment nut.
  • High torque, powerful metal gear servo factory-fitted for increased reliability when you need it most.
  • Swaybars fitted for zero chassis roll in tight turns: 2.5mm front, 3mm rear
  • No e-clips anywhere! The Pulse uses strong steel hex-head screws with locknuts to secure the suspension in place.
