VEHICLE: ARRMA GRANITE BLS
TYPE: 1/10-scale RTR electric 2WD monster truck
PRICE: $249.99 (item no. ARAD42)

HOP-UP: Hitec HS-646WP High voltage, high torque, analog waterproof servo
Price: $42.99 (32646W)
Vehicles like monster trucks that spin large wheels will tax the stock steering servo. Upgrade to the Hitec 646WP servo which offers waterproofing like the stock servo but more importantly, has much more torque both to turn the tires and to hold them straight during high speed runs.

HOP-UP: Arrma aluminum hingepin brace
Price: $9.99 (AR320157)
Big monster truck tires, along with the speed generated by the brushless motor system, place a lot of strain on the chassis. Beefing up the hingepin brace with an aluminum unit will help keep the chassis solid.

HOP-UP: Arrma aluminum servo arm 24T
Price: $9.99 (AR340056)
While upgrading the steering servo, beef up the servo arm with an aluminum unit. Arrma offers red anodized aluminum servo arms and they are available in the three most popular spline counts: 23T, 24T and 25T.
