🌧 1/10 Electric Rally — Tarmac, Gravel & Mixed‑Surface A complete, competition‑ready rally setup guide for the XV‑01, covering tarmac, gravel, and mixed‑surface WRC‑style running. Designed for scale rally shells including Subaru, Escort, Celica, Delta, and Impreza.

What This XV‑01 Setup Guide Covers

Why the XV‑01 Is the Gold Standard for Rally

The XV‑01’s front‑motor, front‑biased belt‑drive layout gives it:

• Exceptional front‑end bite
• Natural rotation on loose surfaces
• Stability under braking
• Realistic WRC weight transfer

It behaves more like a real rally car than any TT‑02‑based platform.

Baseline XV‑01 Rally Setup (Start Here)

These settings work on tarmac + gravel and suit all rally shells.

Ride Height

The XV‑01 has excellent suspension travel — use it.

• Tarmac Rally: 10–12 mm
• Mixed Surface: 12–14 mm
• Gravel / Loose Dirt: 14–18 mm

Lower = sharper response. Higher = more bump absorption.

Droop (Critical for Weight Transfer)

Measured under the arm with droop gauge blocks.

• Front: 6.0–7.0 mm
• Rear: 7.0–8.0 mm

More droop = more grip on loose surfaces. Less droop = more precision on tarmac.

Camber

• Front: –1.0°
• Rear: –1.5°

Rally prefers flatter tyres for uneven terrain.

Toe

• Front: 0° to 1° toe‑out
• Rear: 1°–2° toe‑in

Toe‑out = better turn‑in. Toe‑in = stability on power.

Tyres & Inserts (Most Important Factor)

The XV‑01 responds dramatically to tyre choice.

Tarmac Rally (UK Roads / Car Parks)

Recommended:

• Ride 36 Rally Block
• Tamiya Rally Block (50476)
• Sweep EXP Rally

Inserts:

• Medium closed‑cell

Gravel / Loose Dirt

Recommended:

• Ride 33 Rally Block
• Sweep Gravel
• Tamiya Rally Block (50476)

Inserts:

• Soft to medium
• More sidewall flex = more grip

Wet / Muddy Conditions

• Deep‑lug rally tyres
• Soft inserts
• Vent wheels to prevent water ballooning

Shocks & Oils (Rough‑Surface Control)

The XV‑01 benefits from softer damping than touring.

---

Belt‑Drive Protection (Essential for Rally)

The XV‑01 is robust, but gravel can damage belts if unprotected.

Must‑do items:

• Keep the belt cover installed
• Tape over the belt access slot
• Use rubber‑sealed bearings
• Grease the front pulley area lightly
• Fit a rally bumper or foam block

Optional but recommended:

• Dust‑proof servo tape around steering posts
• Mesh over the front intake vents

Motors & Gearing

• Motor & Power System Guide for motor types, ESC settings, and FDR tables.

---

FDR – Gearing for Rally (13.5T / 17.5T)

Rally requires cooler gearing due to constant load.

Target motor temp: 55–70°C

---

Weight Balance & Chassis Setup

Battery Position

• Forward: More steering on tarmac
• Rearward: More traction on gravel

Chassis Flex

• Rally prefers more flex
• Loosen top‑deck screws slightly
• Use softer plastic arms if available

Handling Problems & Quick Fixes

Understeer (won’t turn)

• Add front toe‑out
• Softer front springs
• More front droop
• Move battery forward

Oversteer (rear steps out)

• Softer rear springs
• More rear droop
• Move battery rearward
• Add rear toe‑in (if adjustable)

Bouncy on gravel

• Softer oil
• More droop
• Softer inserts

Bottoming out

• Increase ride height
• Stiffer springs
• Add internal shock spacers
