Can-Am RC Side-By-Side | Build It, Drive It, Fix It

An RC side-by-side is a remote UTV buggy built for dirt runs, with tunable suspension, sealed electronics, and swappable parts.

If you like the stance and attitude of a real side-by-side, an RC version scratches the same itch without the big-ticket upkeep. It’s a compact rig you can tune, break, repair, and tune again. And each change shows up the next time you pull the trigger.

This article covers what makes a Can-Am-inspired RC side-by-side feel “right,” how to choose a solid base, what parts matter most, and how to keep it running when the fun gets messy. You’ll get practical setup targets, sanity checks before you buy upgrades, and a clean troubleshooting flow for the stuff that ruins a weekend.

What makes an RC side-by-side feel like the real thing

Side-by-sides have a few visual cues that sell the look: a wide track, a low roofline, long-travel suspension, and tires that look more like off-road rubber than street tread. On an RC build, those cues come from proportions and setup, not decals.

Stance and track width

A good stance looks planted. It also keeps the truck from bicycling in turns. Wide arms help, yet the easy win is wheel offset and a tire that fills the wheel well without rubbing at full lock.

Suspension travel that works, not just looks tall

Long shocks and soft springs can look right on the bench, then bottom out nonstop on dirt. Travel matters, yet damping matters more. You want the rig to compress, settle, then rebound once.

Body fit that doesn’t fight the chassis

Many “UTV” bodies are made to fit a narrow range of wheelbases and cage layouts. A clean fit comes from matching wheelbase first, then trimming carefully, then setting body posts so the shell sits level.

Picking the right base before you buy upgrades

The fastest way to burn money is upgrading a platform that can’t handle the kind of driving you want. Start with your terrain, your speed target, and how much wrenching you enjoy.

Choose your scale by where you’ll run it

Small scales can be a blast in tight spots, yet they get bounced around by rocks and roots. Larger scales roll over rough ground better, weigh more, and hit harder when they cartwheel. If your area is rutted dirt, leaf litter, and small rocks, a mid-to-large scale usually feels calmer at the same speed.

Decide if you want a “bash” rig or a “trail” rig

Bash rigs are built for throttle, jumps, and mistakes. Trail rigs are built for control, ground clearance, and slow speed torque. An RC side-by-side can do both, yet it feels best when it leans one way.

• Bash leaning: higher speed, tougher arms, better shock shafts, stronger driveline parts.
• Trail leaning: smoother throttle, lower gearing, better tire compound, sealed bearings, tidy wiring.

Look for a drivetrain that matches your abuse level

If you love full-throttle launches and landings, pay attention to the weak links: spur gear material, diff outdrives, driveshafts, and slipper or center diff setup. If you like long dirt loops, look harder at bearing sealing and dust protection.

Electronics sealing and heat management

Dust and water are a tag team. Even “water-resistant” electronics hate muddy grit packed around a motor can. A fan helps, but it needs room to breathe. A sealed receiver box is great, but the wire exits must be snug so dirt can’t sneak in.

Battery safety is part of the deal. Charging and storage errors cause the worst outcomes, so keep your routine tight and boring. The U.S. Consumer Product Safety Commission has a plain-language overview of battery hazards and charger risks that’s worth reading once and keeping in mind when you set up your charging spot: CPSC battery and charger safety notes.

Can-Am RC Side-By-Side setup tips for rough trails

This is where the rig starts to feel planted instead of twitchy. Don’t chase “one perfect setup.” Build a baseline, run a full pack, then change one thing at a time.

Ride height and droop

Set ride height with the battery installed. Press the chassis down, let it settle, then measure. A practical target is enough clearance to avoid constant chassis slap, while keeping the arms near level at rest.

Droop controls how far the suspension extends when the wheels unload. Too much droop can feel tippy in fast direction changes. Too little droop can make the rig skate over bumps. Adjust in small steps, then repeat the same test turn at the same speed.

Springs and shock oil

Springs hold the rig up. Oil controls how it moves. If it bottoms out, you can add preload, go up in spring rate, thicken oil, or add a touch more pack with piston choice. Start with oil changes before you jump spring rates.

Tires and foam choices

Tires are your traction and your suspension in one. Soft compound grips, yet it can roll on the rim if the foam is too soft. Firm foams keep the shape, yet they can feel bouncy on roots. If you run loose dirt, a slightly taller tire with open lugs often gives a calmer feel without touching shocks.

Steering throw and servo saver

Binding steering is a quiet parts killer. If the servo buzzes at full lock, reduce endpoints until the buzz stops. Then check that the tires don’t rub the body at full compression.

Gearing for control and heat

Gearing changes everything. Taller gearing raises top speed, yet it also raises motor heat. Shorter gearing can feel punchier and cooler. If you can’t hold a finger on the motor can for more than a couple seconds after a hard run, back off gearing or improve airflow.

Parts that change the feel the most

Some upgrades change the look yet do nothing for how it drives. Others change the feel on the first corner. Spend on the parts that move the needle.

Shocks and shock shafts

Leaky shocks ruin consistency. If your rig pogo-sticks, rebuild first: fresh o-rings, correct oil level, clean shafts. If shafts are bent, replace them. A straight shaft is cheaper than a ruined shock body.

Arms, hubs, and steering links

Arms take hits. Hubs and steering links take the blame when the front end clips a rock at speed. If you upgrade, pick parts that don’t turn the rig into a brick. Some flex saves the rest of the chassis.

Differentials and center drive

Diff setup is the hidden lever. Thicker diff fluid can tame front wheel spin and pull the rig out of turns with less drama. Too thick can push wide. If you run mixed surfaces, a moderate baseline is easier to live with than a maxed-out setup.

Threadlocker where it counts

Metal-to-metal screws back out from vibration. Threadlocker fixes that, yet you only need it on the right fasteners. A medium-strength formula that still allows hand-tool removal is the normal pick for RC hardware. Henkel’s technical sheet describes the intended use and removal level for Loctite 242: LOCTITE Threadlocker Blue 242 technical data.

Build checklist that saves time on the first run

Before the first hard pack, do a quick pass that prevents the classic “two minutes in, five parts out” moment.

1. Check every wheel nut and re-check after the first battery.
2. Set steering endpoints so the servo doesn’t strain at full lock.
3. Confirm gear mesh, then re-check after one run if the motor mount is new.
4. Look for dogbones or driveshafts that bind at full droop.
5. Route wires away from the center driveshaft and spur gear.
6. Make sure the body clears the tires at full compression.
7. Bring a small kit: wheel wrench, hex drivers, spare body clips, tape, zip ties.

Baseline setup targets for a Can-Am-style RC UTV

Use the table below as a starting point. It’s meant to get you close on day one, then you tune from your dirt, your tires, and your throttle habits.

Area	What to set or choose	Why it helps
Ride height	Arms near level at rest	Steadier cornering with enough clearance
Droop	Moderate extension, no “dangling” stance	Less tippy feel in fast transitions
Shock oil	Start mid-range for your platform	Controls bounce without making it harsh
Spring preload	Just enough to stop constant bottom-outs	Keeps chassis off the ground on rough dirt
Tires	Open-lug off-road tread	More bite in loose soil and leaf litter
Foams	Medium foam, firmer if it rolls	Supports sidewalls in corners
Gearing	Conservative pinion to start	Lower motor heat and longer run time
Steering endpoints	Reduce until servo buzz stops	Protects servo gears and saves battery
Fasteners	Threadlocker on metal-to-metal only	Stops screws backing out from vibration
Bearings	Sealed bearings if you run dust or mud	Longer service life between cleanings

Running routine that keeps parts alive

Most breakages come from two things: heat and grit. A simple routine lowers both.

After-run cleaning that doesn’t wreck bearings

Knocking off loose dirt is fine. Blasting bearings with water is not. If you use water, keep it light, avoid direct spray at bearings, then dry the rig and add a tiny bit of bearing oil where your platform allows it.

Heat check and gearing sanity

Heat creeps up as the drivetrain wears and dirt packs in. A motor fan helps, yet you still need to check temps after a hard run. If heat is rising over time, clean first, then re-check gear mesh, then look at gearing.

Battery habits that reduce risk

Charge on a non-flammable surface, stay nearby, and don’t charge damaged packs. Store packs at storage voltage when you’re done for the day. If you want a straight-to-the-point safety list for lithium batteries, NFPA’s guidance is a solid read: NFPA lithium-ion battery safety.

Common problems and clean fixes

When something goes wrong, it helps to treat it like a small system check. Start with the simplest cause, then move toward parts replacement only after you’ve ruled out the basics.

Symptom	Likely cause	Fix
Steering jitters at idle	Loose servo saver, weak BEC, noisy connection	Check plugs, tighten saver, test with fresh receiver battery source
Clicking under throttle	Stripped spur/pinion, worn diff gear	Inspect gears, reset mesh, rebuild diff if teeth are damaged
Pulls hard to one side	Toe out mismatch, binding hub, tire foam collapse	Reset alignment, check bearings, swap tires left-right to test
Overheats after short runs	Gearing too tall, packed dirt, tight drivetrain	Clean, check driveline free-spin, drop pinion size
Random cutouts	Low-voltage cutoff, weak battery, loose connector	Test with known-good pack, inspect connectors, set correct cutoff
Bottoms out and slaps chassis	Oil too thin, springs too soft, ride height too low	Thicken oil, raise ride height slightly, tune preload
Diff leaks	Pinched gasket, worn o-ring, overfilled case	Rebuild with fresh seals, check case screws, fill to spec
Wheel wobble	Loose hex, bent axle, worn bearing	Tighten, replace hex, inspect axle, swap bearing

Upgrades that pay off after you’ve got a baseline

Once the rig runs a full pack without drama, upgrades make more sense. You’ll know what you’re fixing, not guessing.

Better tires before more power

Extra power feels fun, yet traction and control let you use it. Tires that match your dirt can make the rig feel new, even with the same motor.

Servo reliability for heavier UTV bodies

UTV bodies and cages add weight up high. Steering loads rise fast when you run sticky tires. If your servo runs hot or chatters under load, a stronger servo and a clean endpoint setup will feel calmer.

Shock tuning for your style

If you jump, tune for landing. If you run rough trails, tune for chatter control and stability. Keep notes: oil weight, piston, spring, ride height, droop. A phone note after each run beats memory.

Buying parts without getting stuck

RC side-by-side builds can turn into a parts hunt if you mix platforms. Before you click buy, match these basics:

• Wheelbase: body and chassis should match, or you’ll cut so much you lose the look.
• Hex size: wheels must match your hub hex.
• Shock length: too long can bind driveshafts at full droop.
• Battery tray: confirm the pack fits with room for straps and wires.
• Spare parts access: keep wear parts easy to get: arms, hubs, spur, driveshafts.

Final setup loop you can repeat every time

Here’s a simple loop that keeps you from chasing your tail:

1. Run one full pack on your normal route.
2. Write down two issues you felt, not ten.
3. Change one thing that targets the bigger issue.
4. Run the same route again at the same pace.
5. Keep the change only if it shows up on the ground.

That’s how a Can-Am RC Side-By-Side build turns from a cool-looking shelf piece into a rig you trust to run hard, get dirty, and come back for more.
