Stiff aluminium servo base for B-Max4

This aluminium servo mount is supplied as a direct replacement for the B-Max4 chassis to provide a stable fixing point for standard RC servos on this platform. It aims to minimise deflection at the servo mount so steering inputs remain consistent during suspension movement.

Constructed from aluminium, the mount offers improved stiffness compared with common plastic parts. That stability aids in maintaining steering geometry, which is important when fine-tuning toe, trim, or steering endpoints.

Installation is straightforward for those experienced with B-Max4 maintenance: the part sits in the original servo area and uses the existing mounting holes. After installation, check servo horn clearance and linkage geometry before locking in final trim values.

Specifications

  • Item: Servo mount
  • Material: Aluminium
  • Model Number: YOKBM200L
  • Compatibility: B-Max4 chassis

Opt for this aluminium mount to firm up the servo mounting on the B-Max4 chassis and to improve consistency when setting up steering characteristics.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does a rigid mount change steering feel?

A stiffer mount reduces unintended movement at the servo, which makes steering responses more direct and consistent, especially when making precise trim or toe adjustments.

Will this affect servo centring or endpoint settings?

It can make centring and endpoints more repeatable because the servo mounting plane is more stable; always recheck trim and endpoints after fitting.

Is there a weight penalty to consider?

Aluminium is typically heavier than polymer alternatives, but the increase is small; the trade-off is improved stiffness and more predictable handling during setup.

Which servos work best with this mount?

Standard 1/10 scale servos that match the B-Max4 servo footprint are suitable. High-torque digital servos benefit most from the firmer mounting surface.
