Most Arrma Typhon 3S owners start upgrading the car too early.
The chassis is already fast enough to expose weak setup habits, rough throttle control, and poor tyre choices long before it genuinely needs huge power upgrades.
That is why so many “fully upgraded” Typhon builds still feel nervous on rough dirt, overheat after back-to-back packs, or push wide in corners despite hundreds spent on alloy parts.
This guide is not about building the fastest Typhon 3S possible.
It is about making the car easier to drive, more reliable over full sessions, and more enjoyable on the surfaces most owners actually use: dusty car parks, loose dirt, rough pavement, and uneven grass.
Upgrade Order Matters More Than Upgrade Cost
This is where beginners usually waste money.
A Typhon 3S with poor steering precision, wrong tyres, and overheating electronics does not become better because you installed aluminium shock towers and a bigger motor.
The car is not faster if it cannot use the grip.
Fix upgrades in the wrong order and every expensive part after that becomes harder to judge properly.
So here is the upgrade path I would actually recommend after real ownership.
Buy First: A Better Servo
The stock Typhon 3S servo works, but it is one of the first limitations you notice once the car starts seeing rough outdoor use.
After repeated runs on rough car park asphalt and loose dirt, the steering starts feeling vague under load. The wheel reacts at the transmitter, but the front tyres hesitate slightly before settling into the corner.
That delay matters more than beginners realise.
A stronger, faster servo immediately makes the chassis feel more predictable over bumps and during quick direction changes. You notice it most on dusty surfaces where the front tyres are constantly fighting for grip.
This is also one of the few upgrades that improves both bashing and controlled driving.
Just avoid the beginner mistake of buying the cheapest “high torque” servo online without checking durability or waterproofing. A servo that develops slop after a few wet sessions is not an upgrade.
Why Servo First?
- Better steering precision on rough surfaces
- More confidence during braking and turn-in
- Reduces vague handling feeling beginners blame on tyres
- Helps the chassis settle faster after bumps
This is the line I would not skip.
Buy Second: Tyres That Match Your Surface
The stock tyres are decent general-purpose options, but no tyre works perfectly everywhere.
That becomes obvious after a few packs.
On loose gravel, the Typhon 3S can feel unstable under power as the rear tyres fight for traction. On dusty driveway concrete, wheelspin masks throttle control problems and creates extra heat in the drivetrain.
Most people reach for more power here. They should reach for better tyres.
Surface matters.
For rough dirt and loose dust, prioritise rear stability and predictable side bite. For smoother asphalt or compact dirt, focus on reducing ballooning and improving consistency through longer runs.
This is also where beginners discover an important RC truth: tyres change the car more than most alloy parts ever will.
Check the tyres after five minutes, not after one hero lap. If the inside edges are overheating or ballooning badly on long straights, the setup is already telling you something.
Nice Next: Cooling Upgrades
Cooling upgrades are not exciting, but they solve real ownership frustration.
The Typhon 3S generates noticeable motor and ESC heat during repeated high-speed sessions, especially on rough public surfaces where the car constantly accelerates from low speed.
This becomes worse when beginners copy gearing setups from speed-run videos.
When the ESC fan is screaming after repeated full-throttle passes, the gearing is telling on you, not the electronics brand.
A quality cooling fan setup and sensible gearing help the car survive full battery packs consistently instead of feeling strong for three minutes before thermal fade appears.
Cooling Upgrades Worth Considering
- Reliable ESC fan replacements
- Motor heatsink and fan combo
- Sensible pinion gearing for the real surface
- Better airflow around electronics during dusty sessions
The part is not expensive. The repeat overheating is.
Suspension Tuning Before More Power
This is where many Typhon 3S builds go backwards.
The chassis already has enough power to expose suspension weaknesses on rough terrain. Adding more motor or aggressive gearing before fixing suspension setup usually creates a harder-to-drive car instead of a faster one.
If the car skips across rough pavement, bottoms out unpredictably, or traction rolls after quick steering corrections, focus on setup first.
Check these before adding power:
- Shock oil condition
- Suspension arms dropping freely
- Ride height consistency
- Bent hinge pins after crashes
- Tyre condition and insert wear
A Typhon with properly working suspension feels dramatically calmer over uneven terrain.
That is especially noticeable on loose dirt where cheap power upgrades simply overwhelm the rear tyres.
Skip For Now: Heavy Alloy Upgrades
This is where YouTube builds and real ownership split apart.
Heavy alloy arms, towers, and steering parts often make the Typhon 3S feel more impressive on the bench while making crashes more expensive and handling less forgiving.
Plastic flex is not automatically weakness.
A flexible suspension arm can absorb impacts that would otherwise transfer force deeper into the chassis. Cheap alloy upgrades often remove that safety margin.
Then beginners discover the real cost after rough landings:
- Bent hinge pin mounts
- Bulkhead damage
- Added chassis weight
- Steering bind after impacts
- More difficult suspension tuning
That cheap chassis becomes less cheap very quickly.
Unless you are solving a specific durability problem you have personally experienced, most beginners should leave heavy alloy upgrades alone.
The Best Typhon 3S Upgrade Philosophy
The best Typhon 3S upgrades are the ones that improve consistency.
Not just speed.
A reliable steering system, tyres matched to the real surface, manageable temperatures, and properly working suspension make the car dramatically more enjoyable over full sessions.
That is what experienced owners usually learn after the expensive phase passes.
Bottom line: fix steering, grip, cooling, and suspension before chasing huge power or alloy bling. The Typhon 3S already has enough speed to teach you the rest.
