BMK B1 Remote DT & Timer

Regular price £25.99

   US-Canada Customers! You can find this product on J&H Aerospace US


Remote DT B1 is the ultimate remote dethermalizer/timer for small free-flight models. Not only for competition models, but for others that we do not want to lose, but also do not want to put an expensive and heavy DT system on them. It also works as a rubber to electric flight conversation system. 



The Transmitter:

The transmitter, which is the size of a matchbox, features a single-button interface for activating or deactivating receiver functions. Each digital transmitter has a unique transmission code and operates using a single CR2032 coin cell. The receivers learn the code during the binding process, so a single transmitter is sufficient for an unlimited number of receivers.

 



The Receiver:

 The receiver offers 9 different modes, such as Servo, Band Burner, and E20 motor control functions. It is specifically designed to operate with a 1S LiPo battery, although any power supply between 3-9V can be used. Please note that the output is not regulated and will match the input voltage, so it is important to ensure that your output devices (such as servo, motor or band burner) are capable of functioning at the battery voltage.

Timer D/T Modes

1- Servo Toggle Servo travels from left to right when the timer countdown is completed or the Remote DT button is pressed. It travels back when the button is pressed again and so on. You can cancel the DT operation in mid-air if you are using a pushrod-operated DT system.
* The Servo Toggle modes may not be suitable for the competition because you have full control of the servo. Please consider Mode 3 or 4.
2- Servo Toggle - TRISTATE
Same as Mode.1 but the servo travels between 3 positions(left-centre-right) by the remote.
3- Servo Cycle
Ideal for the competition models. Servo travels from left to right for 2 seconds then returns to the arming position automatically.
4- Servo One Way
Ideal for the competition models. The servo travels from left to right with no return.
The onboard timer button click is required to return the arming position.

5- DT Motor - Band Burner Mode
Ideal for a lightweight setup. You can use geared micro electric motors, hacked servo, band-burner etc.
The output will turn on for 2 seconds with the remote DT or the timer will do the job automatically when the countdown is complete. The remote DT process can be repeatable in case of a failed DT action.

6- Electric Flight Motor (Timer> OFF, Remote DT> OFF) Competition mode
Ideal for E20 model competitions. The motor output will be turned on when the onboard button is released(hand lunch). You can turn it OFF with the remote or the timer will do the job automatically when the countdown is complete.
7- Electric Flight Motor (Timer> OFF, Remote DT> ON/OFF) Electric model fun mode
Ideal for E20 model fun flights. Same as Mode 6 but the remote can be on and off the motor whenever you like.
8- Electric Flight Motor + 2 Seconds Delay + Ramp (Timer> OFF, Remote DT> OFF) Indoor Competition mode
Ideal for indoor ROG/ROW (no push or hand-launch). 2 seconds after the onboard button is released, the engine starts smoothly. You can turn it OFF with the remote or the timer will do the job automatically when the countdown is complete.
9- Electric Flight Motor + 2 Seconds Delay + Ramp (Timer> OFF, Remote DT> ON/OFF) Indoor Fun mode
Ideal for indoor ROG/ROW (no push or hand launch). Same as Mode 8 but the Remote DT can be on and off the motor whenever you like.






    Notice:

    1) The DT Delay(Abad+) function introduced on 18 September 2023 is available for the new timers from this date. You can delay the DT time by using a compatible BMK SkyLink 434Mhz hand unit



    Questions and Trouble Shooting

    • The Receiver is not responding to the remote DT when the servo is attached.
      Unfortunately, your servo is not compatible with this timer. Some servos have a conflict with the receiver design and the receiver will not respond to the remote DT if that happens. Please try a different servo model.

    • The Transmitter LED is blinking fast.
      Replace the battery with a quality CR2032
    • The Transmitter is not working.
      Check the battery / Replace the battery

    • Can I use an external button for the timer?
      Yes, just solder a button between the external button pads to extend the onboard button features.
