Using an onboard accelerometer, the timer automatically adjusts motor power based on what your aircraft is actually doing, not just what you programmed it to do. The Climb\_and\_Dive timer is the only timer that combines both an active timer and a governor timer in one package. This results in even more savings as it works seamlessly with lower cost (non-governing) ESC's. All user settings are easily programmable via a wireless Bluetooth connection. Fully detailed assembly, programming and operating instructions can be found here: [**Climb\_and\_Dive Timer - Assembly and Operating Instructions**](https://circuitflyer.com/Climb_and_Dive/ "The Best Timer in the World (at least until I make my next one)"). #### How is it constructed? A finished timer consists of two main parts: The first part is the Climb\_and\_Dive backpack assembly. It includes: (1) Climb\_and\_Dive backpack; assembled, tested and ready to go, plus (1) 5 pin strip of right angle breakaway header plus (1) 2 pin 'Dupont' style connector with leads. The second part is a Seeed Studio Xiao nRF52840 microcontroller board. It is supplied preprogrammed with the latest timer code plus (2) 7 pin strips of breakaway header. When both parts are stacked up and soldered togther they form a complete unit. **The timer normally ships fully assembled, preprogrammed and ready to install. If you would prefer an unassembled kit, please select the Unassembled Kit option - soldering skills will be required to join the boards together. All kit components are preprogrammed, tested and ready for assembly.** You also have the option to purchase individual circuit board assemblies. **NEW:** As a seperate accessory, I also offer a remotely mounted push-button switch and super-bright indicator LED in an easy to mount package. See the **Extras** tab above. More details can be found here: [**Control\_Panel - Installation Instructions**](https://circuitflyer.com/Control_Panel/ "Remote Timer Interface"). #### What motivated you to design it? Electric power is the future of control line model aviation. I found there is a limited selection of affordable timers with advanced features. Using the latest microcontrollers, there's no need to break the bank nor make things overly complicated to enjoy the benefits of modern active control technology. #### What makes it different from other control line timers? - Keeping it as a two part device keeps the costs down. Using an assembled PCB in a backpack format greatly simplifies wiring. Pairing it with an off-the-shelf microcontroller reduces complexity. - The timer code is programmed in CircuitPython. Making it super easy to program and keep up to date with the latest version. - The timer code combines advanced features found in other timers into one low cost package. - The circuitboard includes a 3 axis accelerometer. All three axis outputs are routed through a low pass filter before passing to the microcontroller input pins. This allows the timer to act as an active controller to boost the throttle in a climb and reduce it in a dive. A desirable feature to help keep the model velocity more consistent. - It also includes the necessary RPM signal conditioning circuitry to convert the analog motor voltage signal into a digital output. This allows the timer to control the motor RPM and hold it steady through a governing PID control loop. Additionally, the motor shuts down instantly in a crash or nose-over to protect the electrical system from overcurrent. - Best of all, user settings are programmable via a wireless Bluetooth connection using a *free* app. - It's open source. Please hack away and share your own innovations and improvements. ## Shipping policy All products ship via Canada Post. I've selected the lowest rates both with and without tracking where available. USA customers: import tariffs and fees apply and and are collected at checkout prior to shipment. Tariffs are not refundable. EU customers: for orders under €150, Lectronz will handle VAT allowing me to ship direct to your door without delays or additional fees. Please contact me if you have any questions. Important: For countries that require a mandatory tax code or ID number for customs clearance please enter the appropriate information either in the 'Customer Reference Number' field or in the 'Add a note to your order' box at checkout. EU Customers: Canada Post is now allowing parcel shipments valued at less than €150 with EU duties and handling fees prepaid (DDP) to select European countries. Lectronz will automatically add the fees if your country is eligible. All other available EU countries, and parcels valued at over €150 will ship with duties unpaid (DAP) and you may be responsible for paying these fees upon arrival. Unfortunately, for the time being, Canada Post service is still suspended for Czech Republic.
