JP Hobby ER-150 V1 Tricycle Retract Sequencer (HV)

The JP Hobby ER-150 V1 is a precision electronic sequencer designed to manage the deployment of tricycle electric retract systems. This high-voltage (HV) control box serves as the "brain" of your landing gear, ensuring perfect timing between your gear doors and retract mechanisms. Engineered for aircraft utilizing the ER-150 series retracts, this Version 1 controller is a lightweight, reliable replacement for pilots who do not require integrated wheel braking.

⚠️ Version 1 Sequencing Logic

Logic Style: This Version 1 controller is programmed to keep the gear doors OPEN when the landing gear is in the down position.
Critical Warning: Servos used for gear doors MUST be High Voltage (H.V.) type. Using standard voltage servos will result in immediate failure.

Key Features

  • Streamlined Sequencing: Automatically coordinates the movement of two main gears, one nose gear, and two dedicated door servos.
  • HV Compatible: Optimized for 2S LiPo input (7.4V - 8.4V) to provide maximum torque to your retract motors.
  • Ultra-Lightweight: Weighing only 22g, this unit is perfect for airframes where weight management is critical.
  • Simple Setup: Plug-and-play operation using a single gear channel from your receiver.
  • Compact Design: Measuring only 10mm thick, it easily fits into tight electronic bays and fuselage compartments.

💡 Gator-RC Modeler’s Tip: Powering for Performance

Because this unit handles both the gear doors and the main retract motors, we recommend using a 2S LiPo with at least a 1000mAh capacity. This ensures the unit has enough "burst" current to cycle all components simultaneously without sagging the voltage.

ER-150 Sequencer vs. ER-150 Brake Controller

Choose the right "brain" for your JP Hobby retract system based on your airframe's weight and braking requirements.

Feature ER-150 V1 (Sequencer Only) ER-150 V1-B (With Brakes)
Primary Function Gear & Door Sequencing Gear/Door Sequencing + Wheel Braking
Integrated Brake Module No (Requires separate brake unit) Yes (Built-in)
Logic (Gear Down) V1: Doors Stay Open V1-B: Doors Stay Open
Weight 22g (Ultra-Lightweight) 50g
Thickness 10mm (Slim Profile) 21mm
Best For Prop planes or jets with manual/no brakes Turbine & EDF Jets using JP Electric Brakes

💡 Decision Tip:

If you are already using JP Hobby electric wheels with brakes, the ER-150 V1-B is the cleaner choice as it eliminates the need for an extra brake control box. If you are flying a lighter airframe without brakes, the ER-150 V1 saves you space and half the weight.
