This is the 2020 “Mk3” model of tiny single function DT timer designed by Liav Hershkoviz and Bernard Guest with input from George Bredehoft for free flight model airplanes. See my product video here and an older video by George Bredehoft of Volare Products here. This new model is basically the same electronics as the previous models but with the power jack changed to a tiny JST jack (lighter and takes less room) and also moved to the front of the timer so that the battery can be unplugged and charged without removing the timer from the model. I supply this timer as the raw unmounted timer by itself or mounted into a case with battery included. You will also be asked to select the cable length and have the option to purchase a larger remote start button that can be mounted away from the timer.

RDT: You can order an RDT version of the timer with a 3 pin connector. You will be asked to tell me whether you want the pins on the front side of the timer (for external RDT) or back side (internal). You will need to provide a pigtail that connects the timer to the RDT unit.

Remote Start Switch(RSS): Some people find the start button on the timer to be small. Also you may want to have the start button located at the place where you hold your model for launch so that you can press and hold it prior to launching your model. I offer two types of remote start button for this timer. A standard push button timer and a magnetic reed switch. The magnetic reed switch is activated by a small magnet (any small strong magnet will work) and allows you to start the timer by simply applying the magnet for 3 seconds and then pulling it away. This is useful for applications where it is inconvenient to press a button on launch (e.g. tow line glider). If you choose a remote switch you must select the length of the cable based on where you want the start button relative to the timer location.

Power : If you do not need the RDT functionality and you really prefer the old style 2.5 mm power jacks I can convert the RDT pins to take the power from a JR style servo plug. If you would like this option please get in touch and I will do it for you: hummingbirdmodelproducts@gmail.com

An older instructional video by Liav is here. Note that this video includes some detail on how the timer can be used for simple F1H and A gliders that require timer start at towline release (16:30 in). You can exit the video at these times if you do not need this functionality. The servo functionality mentioned in the video is now defunct. this is a band burner only timer.
