1st Buffer-Pack 25F V4.12 for Helis 450-700 # 1st9542 51,99 €

1st Buffer-Pack 25F V4.12 for Helis 450-700

The new version of 1St Buffer has been upgraded.
You can use the buffer as usual, but switching off the buffer is now even more convenient.
In addition to the button on the buffer itself, the buffer can now also be switched off via a channel in the receiver with an assigned switch.
This is a great advantage, especially for models in which the buffer is installed inaccessible.
To do this, the buffer is connected to a free slot and a switch is assigned for this channel, which toggles it from -100 to +100.
The buffer uses its LEDs to indicate whether it is in the process of being switched off.
If it is in operation and supports the system, the red LED flashes as usual.
When charging, the green flashes.
When it is full, all LEDs light up.
After the switch is pressed, the buffer flashes red and green alternately for a short time and then switches off.
Don't worry if you use it incorrectly.
If you accidentally launched the model in the buffer from position, there is no risk.
The buffer must first be switched to the on position and then to the off position before it turns off. This minimizes the risk of switching off the buffer unintentionally. Likewise, some time passes before switching off, so that in the event of an accident, the switch can be quickly switched back to Pos on.

HOBBYWING DC-Booster for 1s Lipo, Output 6V 2 Ampere # HW30601000 30,90 €

Wed, 11 Mar 2026 00:15:59 +0100

DC-Booster for 1s Lipo, Output 6V 2 Ampere

1S DC-DC BOOSTER is a DC-DC power booster module which can draw power from the 1S Lipo battery then boosts it to the voltage (6V) suits the receiver & servo and provides the continuous output current up to 3Amp.
1S DC-DC BOOSTER is mainly applied in 1/12th scale RC vehicles.
The 1/12th scale car usually uses 1S Lipo battery, and BEC in ordinary speed controller is step-down. In that case, the BEC output voltage will be lower than 4.2V that cannot meet the power demand of the receiver & servo. Therefore, 1/12th scale car has to run with purpose-built 1S ESC with the built-in DC-DC booster or external receiver battery connected if the speed controller hasn’t the built-in DC-DC booster. However, things will be different after adopted this booster. Then the receiver batteries can be abandoned and users can be free from charging and maintaining the receiver batteries.

Specification

Input Voltage: 1S Lipo or 3-4 Cell NiMH
Output Voltage: 6V
Output Current: Continuous 3A, Burst 6A
Dimension: 28.0mm*26.8mm*11.8mm (L*W*H)
Weight: 10.2g
