G24: ESC Servonaut special for trucks

Servonaut G24

The Servonaut G24 has been specially designed for radio-controlled model trucks and optimized for Servonaut GM32 and GM42 geared motors. Internal software is used to simulate a 4-speed automatic transmission.

Recommended for use with a Servonaut sound module (SM3 or SM7) : The G24 offers a highly realistic sound and driving experience: the engine sound is enhanced by gearshift sounds during acceleration and deceleration.

If connected to two receiver channels, the G24 features cruise control functionality (just like the Servonaut M24 or E22 controllers). If the control channel is omitted, the G24 has normal control behavior (direct forward/reverse) like a S22 ESC without cruise control. Simulated gearshift sounds are made fully automatically.

The G24 is an ESC for brush motors up to 20A. The ESC Servonaut G24 automatically detects 7.2 V (7.4 V lipo) and 12 V (11.1 V lipo) batteries after switch-on and adjusts the cut-off voltage accordingly (lipo saver function).
Caution: Use only NiMH / NiCd batteries with 6 or 10 cells or 2s or 3s lipos!

For a more realistic driving experience, acceleration and braking actions are limited, simulating a heavy vehicle. Thanks to Servonaut EMF brakes, you never lose control, even when driving downhill. High-frequency PWM switching avoids additional engine noise (no whistling).
Two diagnostic LEDs help identify any problems.

The G24 has outputs for brake lights and reversing lights. The brake light operates realistically. The G24 is protected against overcurrent, overload, excessive temperature and low voltage. In these cases, the motor will slow down or stop.

Difference between G24 and G22:

The G24 is equipped with a Bec system, which is more powerful than the Bec system of the G22 and can operate at a supply voltage of 12v without overheating.

The 5v 4A BEC is powerful enough for a receiver and several standard analog servos even under a 12v supply.

Features:

• Operating voltage: 6/10 cell NimH or Lipo 2s / 3s
• Motor current: 30A / 30s - 20A 5mn.
• Switching frequency: 16kHz
• Switching BEC receiver power supply: 5v 4A
• Reversing and braking light: 2 x 700mA, protected
• Protection: Imax, Tmax, Umin (protected against excessive consumption, overheating and low voltage)
• Dimensions: 70x38x9mm
• German and English instructions, French manual by Tecnimodel
• Includes a female BEC socket for parallel powering of a sound or lighting module

Operation - with cruise control:

The G24 uses two receiver channels: the engine control channel (blue socket) operates the engine speed (joystick forward) and the brakes (joystick reverse). With the switch channel (white socket), you can switch between forward and reverse.
With the engine control channel held in neutral, the speed is kept almost constant (cruise control function).
Forward or reverse switching is only possible when the model is stopped.

Operation - without cruise control :

The G24 uses only one lane, the white socket must remain unconnected.
The driving lane (blue socket) now operates the throttle in the most usual way, like a Servonaut S22. In neutral position, the brake is active. To stop the model slowly, move the stick slowly towards the center position. Do not allow the stick to return abruptly to neutral. A small movement away from the center position switches the reversing light on and off.

Operation - Gearbox simulation :

The G24 simulates an automatic transmission.
The vehicle's dynamic behavior depends on the active "gear".
With more throttle applied, the G24 will shift into a higher gear later. Deceleration during gear changes is also simulated, as is clutch engagement.
If the model decelerates slowly, the G24 will shift from one gear to another. With more brake, the G24 will jump out of gear and into the appropriate gear once the brake is released.

A few tips:
The G24 offers an extremely realistic driving experience and, with a sound module Servonaut, perfect sound.

But for best results, you need to drive the model realistically. Don't over-brake or over-throttle, and move the lever gently, especially when driving without cruise control.
