Best Servo for Arrma Mojave

The Arrma Mojave comes ready for high speed action with its brushed 3600KV motor and capable electronics. But upgrading to a faster, stronger steering servo improves the Mojave’s agility and control for racing or tricks. In this guide, we’ll recommend the best servo upgrades for optimizing the Mojave’s handling.

Introduction

While the included servo is decent, it lacks the torque and transit speed for precise performance driving. Upgrading to a servo with faster transit times under 0.10 sec/60° and 200+ oz-in of torque transforms steering response and accuracy.

Key servo features to look for in a Mojave upgrade include:

  • Transit speed under 0.10 seconds for fast response
  • 200+ oz-in torque for resisting binding and crashing forces
  • Metal gears for durability
  • Waterproofing for running in any condition
  • Heavy duty ball bearings that withstand extreme use

We’ll suggest excellent high-end and budget servo options from leading RC brands to improve Mojave steering and control. Let’s dive in!

Key Takeaways for Mojave Servos

  • Look for 0.09 sec or faster transit times for ultra quick steering response.
  • 200+ oz-in of torque prevents servo savers from engaging under big impacts.
  • Waterproof, heavy duty metal gear servos withstand harsh racing conditions.
  • Aftermarket steering mounts improve geometry and weight transfer.
  • Beefier steering rods and drag links protect the servo output shaft.
  • Carefully tune servo endpoints and limit over-rotation travel distance.

Yeah Racing’s HV servo is affordable while still being faster and stronger than stock.

Servo Mounts and Linkages

To get the most from upgraded servos, also install:

Hot Racing Aluminum Servo Mount

  • Anodized 7075 aluminum construction
  • Optimizes geometry and steering precision
  • More consistent steering response

Upgrade the soft stock mount for $16.

Yeah Racing Titanium Steering Set

  • TiN coated titanium steering linkage rods
  • Ultra strong steel turnbuckles
  • Virtually indestructible parts

The $65 Yeah Racing titanium steering set is insurance against bending or breaking steering links.

FAQs

What servo do I need for speed runs?

For max speed runs, faster transit times under 0.08 seconds are critical for quick corrections. Torque becomes less important than pure speed for high speed stability.

How much torque servo does the Mojave need?

For a blend of racing and bashing, aim for at least 200-300 oz-in of torque. This prevents servo savers from engaging under big hits while retaining speed.

Is metal gear train a must for a Mojave servo?

Absolutely, at minimum get an all metal geared servo. The Mojave’s power and big crashes demand metal gears to avoid stripping. Nylon/plastic gears won’t last under extremes.

What mods help servos survive crashes?

Upgrade to aluminum servo horns, add a servo brace bar, limit throttle/steering with AVC mixing, and adjust servo savers to activate earlier. This reduces forces on servo internals during accidents.

How do I mount a bigger servo in the Mojave?

Larger servos usually require mounting modifications like trimming the chassis and fabricating custom mounts and linkage. Take measurements and test fitment before finalizing the mounting plan.

Conclusion

While the Mojave includes a capable stock servo, upgrading to a faster, stronger aftermarket servo makes a world of difference in steering precision and handling for racing, tricks, or blasting through rough terrain.

Faster transit times under 0.10 seconds paired with 200+ oz-in of torque gives you lightning quick response and the strength to resist breakage from big hits and crashes. Just ensure proper gearing and endpoints to avoid overloading even robust servos.

With a high end servo upgrade, you’ll immediately notice tighter cornering and improved control allowing you to push your driving limits with confidence. Your Mojave will handle like never before!
