ElMod 4WD Miniature Central Unit

The universal central unit combines a variety of driving, lighting and sound functions in a compact board. With various expansion options you do not compromise and shape the range of functions according to your needs.

Scope of delivery

• ElMod 4WD board
• Power supply cable
• One cable for the drive motor
• Cable set for analog receiver (eight channels + power supply)
• Volume control and connection cable for loudspeakers
• Four cables for the lighting
• USB dongle with USB cable
• Four double-sided adhesive foam rubber dots for fixing the board in the model

Optional accessories

• FX Expander: servos, turn signals and advanced light functions
• FX SBus: Connects to SBus-compatible receivers. Allows up to 16 channels to be used.
• ElMod Bluetooth: configuration and driving functions via Bluetooth^®

Drive

• 10 A strong, short-circuit and overload protected driver for the drive motor
• Physics engine: realistic driving behavior by simulating mass inertia. The vehicle drives “like a big one”. Acceleration, deceleration, top speed, gear shifting and many other characteristics are simulated.
• All driving parameters are adjustable

Steering

• Steering via steering axe and a servo motor with optional speed-dependent steering traverse
• With optionally available FX Expander: Steering of up to two more individually configurable steering axes via servos with optional speed-dependent steering traverse

Weapons

• With optional FX Expander:
  • MG muzzle flash via LED with adjustable firing cadence
  • Vertical and horizontal adjustment of the main gun with servo motors
• Shot sound of the main weapon

Lighting

• One or two LEDs can be connected directly to all light channels. No further wiring is necessary.
• All light connections are short circuit proof. The LEDs can not be damaged in case of accidental polarity reversal.
• Dimmable front light that can be switched off via the remote control
• Combined tail light with brake light with separately adjustable brightness
• With optional FX Expander:
  • Three additional freely assignable light channels
  • Indicator with warning light function

Servo functions

• With optional FX Expander: connect up to two servos for different functions, for example (list not complete):
  • vertical and horizontal movement of the main gun
  • control of additional steering axis
  • Opening and closing of hatches
  • Operating windshield wipers or radar
• Max. 2 A continuous current consumption for all servos together

Sound generation and noise

• Support of all ElMod sample sets for extra prototypical sound reproduction
• Integrated sound unit plays several different sounds simultaneously
• Sound types drive
  • Multiple starter sounds with distinction between cold and warm start
  • Multiple shutdown and start-up sounds, engine sounds for driving with simulated gear changes and distinction between full load, part load, engine brake and mechanical brake.
  • Turbocharger whistling
• No steps between engine sounds
• Speed-dependent driving sounds such as chain or chassis squeal
• Optional ambient and environmental noises
• Speed-dependent turret rotation noise with optional distinction between drive without and with motor assistance
• Sound for elevation of the main gun
• Fire from main gun optionally as single shot or continuous fire (e.g. flak)
• Variable sounds for bullet impact with simulation of impact at different distances
• Shooting noise for MG
• Up to 24 individual sounds that can be triggered via the radio system, such as horn, radio announcements, etc.
• Plain text announcement when battery voltage is too low/too high
• Configurable volume level of a noise type (e.g. raising the volume of the MG and lowering the volume of the engine) and configuration of multiple sound parameters
• Adjustment of the volume via an included rotary potentiometer
• Adjustment of the volume via a rotary knob on the remote control
• All included sample sets are stored on a PC/notebook-readable microSD card. They may be changed at runtime via the ElMod app.
• Integrated 10 W digital audio amplifier for connecting an 8 ohm speaker
