FlightChip ~ a Programmable, Multipurpose, Low cost, Very low weight, Flight Control System for Electric Model Aircraft, now with a Ready Built & Ready to Connect Option weighing only 3.5g

FlightChip3 is a kit of parts that enables you to build a programmable, low cost, low weight flight control system which incorporates motor run timer, de-thermaliser (DT) servo turn on timer and 9 motor speed settings. The motor run time system can control either a DC brushed motor using the MOSFET supplied, or a brushless motor using a user supplied ESC. The motor run time is 0 to 99 seconds in one second steps and the DT turn on timer is 0 to 990 seconds in 10 second steps ~ all of which can be programmed by the user using a pushbutton and LED. Although designed for use with a single Li-Po you can use 2 or 3 Li-Po’s by fitting the FREE voltage dropping PSU board supplied with the kit, or available as an option with the ready to connect option. The untrimmed components supplied weigh about 1.56g, the 4 wires 1.84g and the PSU board if fitted weighs 1.65g ~ its the servo, ESC, motor and related wiring that adds the weight! So with careful planning you will get a very lightweight programmable system. The kit includes resistors, capacitor, high bright LED, switch, P45N02LDG MOSFET Power Switch (5A continuous, 8A for 60 seconds although you could fit a larger N type MOSFET - make sure the wiring is up to it!), programmed PIC, lengths of wire and FREE voltage dropping PSU Board if you need it. Ensure your system is tried and tested before you launch. We have included the option of FlightChip3 in packs of 10 at a reduced unit price in order to encourage the kit to be selected as one of your club projects for 2016.

FlightChip4 has the same features as FlightChip3 Plus the ability to change the motor speed everytime you press the pushbutton. It works like this.........At launch you press the pushbutton and on release the motor will start at the last set speed. If you then press the button again the motor speed will increase to the next speed. Each time you press the pushbutton the speed will increase until you reach maximum speed. When you press the pushbutton again the speed will drop to zero, and at the next press the motor will increase to speed 1, then 2, then 3, etc . This means you can change the motor speed to suit the flight conditions holding the model ready to launch. The flight and DT timers will restart every time you release the pushbutton.

FlightChip3 and 4 are available built & ready to connect to 1 Lipo & 6/7mm motor ~ this very lightweight assembly weighs 3.5g! If you want to run a 12mm motor we suggest you assemble your own Flightchip ensuring the wire size is suitable. Let us know your timer settings and we will programme ready to go (you can change yourself later if you wish).

We also offer a lightweight 2.5g servo suitable for the DT (weight excludes plug) Free P&P with FlightChip3

We post FlightChip3 and 4 to most parts of the world.

We now have an SMD Kit version of FC3 and FC4 so you can reduce the weight to suit those small indoor models. Simply order as normal quoting SMD. Just remember SMD components are very small so you will need a small soldering iron and maybe a stereo magnifier. The photos below show an FC4 plus a Gyminnie Cricket almost ready to fly. The weight of the FC4, 80mA Lipo, motor and prop are about the same as the rubber & prop supplied with the kit (5.5g).

    The 2 Amp voltage dropping PSU board has a input voltage of 4.75V to 23V DC and an adjustable output voltage of 1.0V to 20V DC, size is 18mm x 12mm x 4.5mm and it weighs 1.65g. The PSU is short circuit protected and will go into a current limit of 2 Amp, it will come out of current limit once the excessive load has been removed. Set at 5V and fix with cyno before use with FlightChip. These are available under "Order FLIGHTCHIP3 Ready to Connect"

    The 2 Amp Step-Up Voltage board has a input voltage of 2.0V to 22V DC and an adjustable output voltage of 2.5V to 24V DC, size is 36mm x 17mm x 14mm and it weighs 4.5g. Ideal for supplying the power to a 5V receiver or 6/7mm motor from a single 3.7V/4.2V Li-Po. The PSU is short circuit protected and will go into a current limit of 2 Amp, it will come out of current limit once the excessive load has been removed. Note that this board will increase the voltage to meet your preset voltage as the battery voltage drops. This helps your model continue to power on. Always set the output voltage to more than the input voltage.

    The CN12 type C brushed motor is a powerful 6 pole 12mm diameter, 30mm long motor suitable for E30 and other electric model planes. The shaft is 1.5mm diameter and 5mm long. Weight is about 15.2g and resistance is about 1 ohm. No load current at 7.2/8.4V is 0.27/0.29 amps. 2 Lipos is the maximum for this motor. These motors have been removed from industrial equipment and have solder on the tags. They are a powerful and useful motor which some flyers are using in competitions.

    The DVP20 operates from a supply voltage of 4.5-30V DC at less than 20mA with a voltage measurement range of 0-100V DC and a current measurement range of 0-10A (built in shunt). The voltage being measured can be used to power the meter if it is above 4.5V. It has trim pots for voltage amd current. The size is 48mm wide, 28mm high, 32mm deep with a cut-out size of 45mm wide, 26mm high. Weight 19 g. See link below for wiring diagram.
