Redcat Racing Blackout SC

Name: Redcat Racing Blackout SC
Brand: Redcat Racing
SKU: RER07115

1/10 scale · short course · RER07115

Redcat Racing's Blackout SC is a four-wheel-drive 1/10 short course truck, sold ready to run with a 550 brushed motor of 16 turns and a waterproof brushed speed control.

It drives a 55T spur and rolls on 100 mm tires with 12 mm hexes. The truck measures 465 mm long on a 290 mm wheelbase and is 285 mm wide. The speed control accepts up to a 3S pack, but a brushed motor on a bigger pack runs hotter, so check it by touch after the first few runs. Redcat's parts list shows two different motor gears, so confirm which pinion is fitted before ordering a spare.

Brushed motor, so there is no KV: compare gearing by rollout.

Specifications

Spec	Value	Basis
Vehicle
Class The kind of vehicle the maker sells it as. It sets what the car is built to do and which cars it is fair to compare it with. Short course trucks copy full-size desert race trucks, with bodies that cover the wheels so they can bump each other without tangling. Drive All four wheels are driven. That gives more grip under power, especially on loose ground. The cost is more parts to maintain. Power A brushed motor carries current through carbon brushes that rub on the commutator. It is cheaper and smooth at low speed. The brushes wear and the motor loses power over time. Build Ready to run: built at the factory with the electronics installed. Some come without a battery or charger; the maker's box contents say which. Scale The maker's nominal size compared with a full-size vehicle. It works more as a class label than a measurement. A 1/10 monster truck is far bigger than a 1/10 touring car, so compare length and weight for real size. This one is 465 mm long. Part number The maker's product number for this exact version. A V2, a new color, or a kit instead of an RTR usually has a different number, and parts can differ between them. Check it against your box or receipt before ordering parts.

Drivetrain
Pinion The small gear on the motor shaft. Fewer teeth gear the car shorter: quicker acceleration, lower top speed and a cooler motor. More teeth do the opposite. It depends on the motor you fit, so the maker does not list one. Spur The large gear the pinion drives. A bigger spur with the same pinion gears the car shorter. Pinion and spur must have the same pitch, or tooth size, to mesh. The Gearing parts table below shows this car's pitch and part numbers. Transmission & axle Every reduction after the spur, multiplied together: transmission, differentials and axle gears. It is fixed by the design; the gearing you change is the pinion and spur. Final drive How many times the motor turns for one turn of the wheels. A higher number is shorter gearing: more acceleration and pulling power, less top speed.

Wheels & tires
Tire diameter The outside diameter of the mounted tire, tread to tread. A taller tire covers more ground each turn, which gears the car taller. At high speed tires can balloon and grow, so the real gearing gets taller as the car goes faster. Wheel hex The hex on the axle that the wheel locks onto and is driven by. A wheel must match the hex size to fit. 12 mm is the common size on 1/10 cars, so most 1/10 wheels fit; offset and width still vary. The wheel nut is a separate size, so check its thread too before buying nuts.

Power
Motor Brushed motors are rated by can size and turns rather than KV, so there is no KV to show. Motor shaft The diameter of the motor's output shaft. A pinion's bore, the hole in its middle, must match it. Battery The highest LiPo cell count the maker rates the electronics for. Each cell is 3.7 V nominal and 4.2 V fully charged. 3S is 11.1 V nominal and 12.6 V off the charger. Running more cells than this risks the ESC and motor. Many cars also run on fewer cells, only slower. Stock motor The motor fitted at the factory, as the maker names it. Brushed motors are often named by can size, such as 540 or 550, and by turns: fewer turns is faster. Stock ESC The electronic speed control. It feeds power from the battery to the motor as you work the throttle, and usually powers the receiver and servo too. An amp figure in its name is normally the maker's continuous rating. A brushed ESC cannot run a brushless motor. Set its low-voltage cutoff for LiPo, so a pack is not run flat.

Performance
Theoretical top speed A brushed motor has no KV rating, so no theoretical top speed is worked out. Compare gearing by rollout instead.

Size & weight
Length Overall length as the maker states it, usually with the body fitted. Useful for comparing real size, since scale labels are loose. Width Overall width as the maker states it, usually with the body fitted. A wider car is more stable in corners and harder to roll over. Height Overall height as the maker states it, usually with the body fitted. Useful when checking it fits a shelf, a bag or a car trunk. Wheelbase The distance between the front and rear axle centers. A longer wheelbase is steadier at speed and over bumps; a shorter one turns more tightly.

How to read these figures

Stock is as the vehicle ships.
Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart.
Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.
Not published means it exists but no source we could find prints it.

About teeth, pitch and bore

Tooth counts are the ones in the specifications above.
Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close.
Bore is the pinion’s hole, listed separately from the motor shaft (3.2 mm on the stock motor).

How these numbers were settled

The Blackout SC manual's exploded view on page 10 lists a BS213-026 marked 'Spur Gear 55T', and Redcat's part page prints 'Spur Gear 55T (.8 Module)' and names the Blackout SC.

The manual shows two different motor gears: the exploded view on page 10 lists BS214-007, while the parts list on page 11 lists BS214-006 marked '18T Motor gear'.
Redcat's part page for BS214-007 names only the Blackout SC Pro, so which pinion is stock is unclear and it is left blank.
The reduction after the spur and the final drive are left blank because the diff unit (BS903-104) and the gear shaft unit (BS213-025) are sold without tooth counts.
The tire comes from Redcat's part page for the black pre-mounted 1/10 SC tires and wheels (BS711-002), which prints an overall diameter of 100mm and a width of 43mm and names the Blackout SC; the manual's parts list shows the same tire.
The manual's specifications page gives 465 mm long, 285 mm wide, 140 mm high without body and a 290 mm wheelbase, with a 7.2v NiMH pack in the box.
Redcat's page for the Hobbywing brushed waterproof ESC (the BS218-015 in the manual) lists the Blackout SC and gives 'Max Battery: 3s 11.1v Lipo', while Redcat's page for the 550 motor lists a 2s limit, so the speed control's 3S rating is used here.
The motor is a 550 brushed can, so no KV applies.
A news post of 14 April 2015 announced the Blackout SC and SC Pro.
