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.
Matchbox size transmitter has a single button interface to activate or deactivate the receiver functions.
Each digital transmitter has its own transmission code and operates with a single CR2032 coin cell.
|Working Frequency||:||434 MHz|
|Range||:||up to 2750m|
|Power Consumption||:||35mA when the button pressed|
|Battery Life (CR2032)||:||>5 years when idle|
|Low Battery Warning||:||<2.5v (flashes 5 times when the button is pressed)|
|Dimensions||:||35mm x 50mm x 15mm|
The tiny receiver has 9 different modes including Servo, Band Burner, E20 motor control functions.
The receiver is designed to work with a 1S LiPo battery but you can use any power supply between 3-9V.
The output is not regulated and same as the input voltage. Just make sure your output devices(servo, motor or band burner) can work 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 competitions 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. 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 a 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.
