RC Maker SP2 1/10th EP Onroad Touring Car

FIRST BATCH SOLD OUT - NEW PRE-ORDERS ARE FOR THE SECOND BATCH (NOV/DEC LIKELY)

RC MAKER SP2 1/10 EP Touring Car Kit

The RC MAKER SP2 is a competition-level 1/10 electric touring car developed from the successful SP1 platform. Following 18 months of development, the SP2 retains the core DNA of its predecessor while being comprehensively re-engineered to improve handling, durability, adjustability and ease of maintenance.

Chassis Options

The SP2 is available with three interchangeable chassis specifications. Select your preferred chassis style from the product options.

• Carbon Chassis: 2.2mm carbon-fibre chassis weighing approximately 63g. Includes front and rear brass centre weights.
• Aluminium Chassis: 1.5mm aluminium chassis weighing approximately 85g. Includes front and rear brass centre weights.
• Steel Chassis: 1.2mm PVD-coated spring-steel chassis weighing approximately 137g. Centre weights are not included.

Each chassis uses the same 110-degree steel countersunk screws, allowing straightforward chassis changes without requiring a different screw set.

Suspension

• XS shocks and springs reduce unsprung weight and improve handling response.
• Coaxial shock and pushrod geometry provides smoother shock action, reduced play and a lower moment of inertia.
• Optimised suspension kinematics improve traction and cornering response.
• Shock bodies are fixed to the bulkheads to reduce friction and unsprung weight.
• Rigid upstop adjustment using a grub screw or screw-and-shim arrangement.
• Suspension arms are 3mm longer with mounting points positioned 6mm closer for improved corner speed.
• Minimal components mounted to the suspension arms help reduce unsprung weight.
• Delrin components and polished steel ball studs minimise friction and wear.
• Adjustable rocker height using a slider system allows quick and precise fine-tuning.
• Steel pushrod components replace conventional ball cups to reduce wear, weight and friction.
• Pinned upper shock mounts provide smoother shock action with reduced play.

Sway Bars

• Ultra-lightweight design with adjustment accessible from above.
• Ball-raced construction allows easy installation and removal.
• Positioned for the lowest possible centre of gravity.
• Minimal component count.
• Compatible with 1.0mm to 1.3mm sway bars.
• Front and rear sway-bar components are fully interchangeable.

Hubs

• Lowered axle height provides a wider tuning range.
• Direct mounting provisions for analogue and digital caster tools.
• Oversized 6 x 11 x 4mm inner bearings improve durability and reduce play.
• Matched polished balls across the hubs and inner arms maximise component compatibility.
• Optimised scrub radius provides a more aggressive steering response.
• Hard-coated wheel hexes minimise play and wear.
• Integrated mounting option for aero discs.

Steering and ARS

• Lengthened rear toe links provide more linear rear toe gain.
• 8.0mm steering rack with optional steering-lock stoppers.
• Consistent ball studs throughout simplify compatibility and spare-parts management.
• Low-CG one-piece servo mount with enlarged locating pins for precise and durable alignment.

Bulkheads

• Top-deck mounting is raised by 4mm for more rigid and progressive chassis flex.
• Raised differential and spool positions improve corner speed and driveability.
• Front-left/rear-right and front-right/rear-left bulkhead compatibility reduces the number of spare parts required.
• Laser-etched belt-tension positions provide clear and repeatable adjustment.
• Increased suspension-arm clearance enables higher roll-centre settings.
• Precision locating pins provide repeatable alignment.

Motor Mount and Top Deck

• Raised motor mount with revised mounting positions and equal-length top decks for centralised chassis flex.
• The motor is raised by 0.5mm, allowing additional chassis material beneath the motor pocket for improved flex and durability.
• Screw-in steel layshaft improves tolerance and durability.
• Larger locating pins provide durable and repeatable alignment.
• Integrated pinion-tightening access hole located underneath the chassis.
• Adjustable front and rear belt tensioners are included.
• Compatible with an optional centre belt tensioner for Modified-class racing.
• Generous pinion clearance and motor adjustment range accommodate low final-drive ratios.
• Cuttable top-deck tabs allow fine-tuning of chassis flex characteristics.

Drivetrain

• Threaded aluminium differential halves provide clearance for the longer suspension arms.
• Optimised differential gear spacing improves durability under demanding conditions.
• Larger driveshaft bearings and a coupler-free design reduce friction and wear.
• Lightweight hardened outdrives and driveshaft components minimise rolling resistance and wear.
• Larger centre-pulley bearings improve rigidity under high loads.
• Improved ball-bearing durability and smoothness throughout the drivetrain.

Bumper and Body Mounts

• Low-CG front bumper assembly improves handling balance.
• Bumper stoppers are integrated into the front bulkhead for easy bumper removal and uninterrupted chassis flex.
• Carbon bumper mount includes an integrated pocket for the INOV8 Adjustable Hood Support.
• Split-style rear body mount reduces moment of inertia and allows adjustment of bulkhead flex.
• Moulded rear body-post spacer reduces weight over the rear of the chassis.

Chassis Design

• Minimised chassis footprint reduces scrubbing during cornering, acceleration and braking.
• Three interchangeable chassis materials provide additional tuning options across different track surfaces.
• All chassis variants use the same 110-degree steel countersunk screws.

Hardware

• High-quality nickel-plated YFS screws are used throughout the top of the car for durability and corrosion resistance.
• High-quality 110-degree countersunk steel chassis screws feature durable 2mm hex drives.

Included Equipment

• Differential tools.
• 1.1mm sway bars.
• Two 4.5-coil springs.
• Two 4.25-coil springs.
• Front and rear brass centre weights with the carbon and aluminium kits only.
