More Than Just a Tabletop Game: A Multi-Layered Hobby

• Warhammer 40,000 (40K): Grimdark sci-fi battles set in the dystopian 41st millennium.
• Combat Patrol: A streamlined, faster-paced version of Warhammer 40K using fixed box sets.
• Age of Sigmar (AoS): High-fantasy battles featuring ancient warriors, gods, and mythical monsters.
• Spearhead: A fast, tactical, and beginner-friendly way to play Age of Sigmar.
• The Horus Heresy: A historical, tragic civil war set 10,000 years before Warhammer 40K, pinning space marine legions against each other.
• The Old World: The return of classic square-base tactical fantasy battles featuring grand armies of knights, elves, and empires.
• Middle-earth Strategy Battle Game: Tactical tabletop gaming set in the world of The Lord of the Rings and The Hobbit.
• Kill Team: A fast-paced, skirmish-level game focusing on small, elite squads instead of massive armies.

How to Get Started

• Observation: The internal shims that sit inside the diff case behind the outdrives are remarkably thick and heavy-duty—roughly 1mm. This is a massive upgrade over brands like Team Associated, which don't even use shims here. The sealing gasket fits with ultra-tight tolerances, creating a perfect leak-proof seal.

• The Trap: When I initially test-fitted the bulkhead cap with finger pressure, the diff had massive play, as if the bearings were missing. However, once I tightened the screws properly, the tolerances seated perfectly, and the excessive play disappeared completely.

• Critique: The molding quality on these plastic inserts could be slightly cleaner. They fit into the aluminum blocks with an extreme press-fit, meaning adjustments trackside will require some serious effort.
• During Step 7 (installing the front sway bar and upper arms), my upper suspension binding felt slightly stiff when using all the provided shims. New competition kits often require a bit of track time to seat and "break in" smoothly.

• The Challenge: While the lower pivot ball caps went into the plastic threads easily, the upper caps required immense force. Fearing I was cross-threading the plastic, I backed them out, but the threads were pristine. The fit is simply incredibly tight. I had to break out a socket wrench handle to leverage enough torque to thread the upper caps completely home.

• Tweak: The rear chassis brace mount requires two screws to mount onto the bulkhead. The kit supplies M3x12 button-head screws, but due to the recessed pocket, the surface contact felt insufficient to me. I substituted them with heavy-duty M3x10 cap-head screws which sat perfectly inside the recess for a much tighter mechanical lock.

• Tweak: The brake guide pins had a very tight fit through the pad backings (likely due to the red paint coating), preventing them from sliding freely. I ran a 3.2mm drill bit through the pad holes to open them up slightly. Once cleared, the brake system operated smoothly.

• Omission: The kit surprisingly lacks servo mounting screws and washers. For a high-end racing kit, these should be standard hardware. Thankfully, I had plenty of M3x12 button-heads in my pit box to complete the installation.

• Great Feature: The lower shock mounting screws utilize reverse-threaded pins on the opposite side of the vehicle, which physically prevents the rotation of the suspension from backing the screw out during a race.

• Final Issue: The kit does not include the wire clip required to secure the front of the air filter housing. Without this brace, the filter element sits loosely under the body shell and rubs against the brake linkage. I have flagged this to the factory to ensure it becomes part of the standard kit layout.

• Plastic Brittle Factor: The vast majority of RC components are molded from composite plastics. In freezing temperatures, these materials rapidly lose their elasticity, become highly brittle, and snap significantly easier upon impact.
• LiPo Battery Protection: Ensure your driving battery is not as cold as the outside air when you start. Your LiPo pack should be pre-warmed to at least 10°C (50°F) before running. Cold batteries suffer from severe voltage sag, which limits power output and can permanently damage the cells under heavy load.
• Snow Means Water: If you are blasting through snow, remember that you are fundamentally driving in wet conditions. Once you bring the car inside, the snow melts, meaning your vehicle will require immediate water-protection maintenance (refer to our previous maintenance guide!).
• Frozen Ground Hardness: The terrain in winter is frozen rock-hard. If you are used to summer conditions where your model effortlessly crushes small dirt mounds or grass clumps, the effect in winter is the exact opposite—the frozen ruts will easily break your suspension components instead.
• Keep Yourself Warm: The cold affects more than just the model—you need to stay warm too. Your hands will be highly vulnerable to the frost. Operating a transmitter with thick gloves is practically impossible due to lost precision, and thin gloves offer minimal protection during extended sessions.
• Nitro/Gas Hibernation: If you own an internal combustion model—especially a nitro engine vehicle—it is highly recommended to put it into actual winter hibernation. Nitro engines cannot maintain their optimal operating temperatures in the freezing cold, and you will ultimately cause more wear and damage to your expensive engine than you get back in driving enjoyment.
• Snow Depth Limits: Deep snow creates massive physical resistance. Unless you are running specialized paddle tires or a heavy-duty platform, the chassis will simply high-center and get stuck.

The Ultimate Winter Alternative: Indoor Tracks and Scale Realism

Time for Tabletop Engineering

• Is it necessary to maintain an RC model, how do I do it, and how often?
• Am I allowed to repair and disassemble the model myself?
• Can I drive my RC car in wet conditions, mud, or snow?

Your Model is Not a Perpetual Motion Machine

"Am I Allowed to Disassemble and Repair the Model Myself?"

1. Pressure washing pushes dirt into bearings: Even though the car looks sparkling clean after a high-pressure wash, it actually isn't. A pressure washer excels at forcing fine sand and moisture deep into places they should never go—such as rubber-sealed ball bearings, hinge pin blocks, and tight gear meshes. The end result is a clean-looking car that suddenly refuses to roll or binds completely.
2. "Waterproof" does not mean rustproof: While many RC cars feature "waterproof electronics" on the box, you must apply common sense. An electric brushless motor will technically run completely submerged under water, but it is not watertight. Problems arise later when the internal iron components—such as the stator, shaft, and rotor bearings—begin to rust. Water and corrosion have a catastrophic, destructive effect on ball bearings.

How to Diagnose If Your Model Needs Service

Pre- and Post-Run Visual Inspection

• Ensure all chassis screws are tight (especially metal-to-metal screws secured with threadlock).
• Clear out any foreign debris (like small rocks wedged near the outdrives or steering rack).
• Check for excessive slop or play in the wheels. A wobbling wheel usually means either the wheel nut has backed off, or the wheel bearings are blown and about to disintegrate entirely.
