Custom, hand-built electronic circuits designed to improve and enhance the fun and thrill of radio-controlled models.
We have now added to our line of Safety-related products the new XT90-S connectors by Amass. Like our No-Spark Arming Plug & Harness, these are designed to eliminate the dreaded spark that often occurs when connecting 6S or larger Li-Po battery packs to the ESC. These sparks are more than just annoying, they create voltage spikes that can damage the ESC, and produce arcing that damages the surface of the connectors, either of which can result in catastrophic failure and the loss of a model. Click on the picture below to go to the product page where you can read more about them.
While you're at it, you might also want to consider our SafeStart system for eliminating unexpected motor starts, and the injuries that come with them. SafeStart can (and we think should!) be used along with a No-Spark Arming Plug or a No-Spark connector to provide the ultimate in protection for you and your model.
We've got some New Products!
In response to customer requests, we're introducing several new circuits this fall. Some are available now, and a few will be available in just a week or so when we get the printed circuit boards needed to produce them.
Wingtip Only NavLights -For models that do not need strobes, landing lights, or any other navigation lights (like WWII warbirds). Red & Green 8mm LEDs, regulated for use with any receiver voltage, Tx switchable.
Heli NavLights -Designed specifically for helicopters, with shorter wires, and smaller 3mm LEDs used for navigation lights, these sets will be easier to install in helis that have thin stabilizers and smaller areas for mounting.
Magneto Kill Switch -For gas engines that have magneto ignitions, this simple switch will reliably ground the magneto terminal and kill the motor.
Simple R/C Switch -Similar to our MultiPurpose R/C Switch, but smaller, this circuit will switch almost anything on/off from the transmitter.
Opto-Isolated Kill Switch -This is a new design of our switch for gas engines that use CDI ignition boxes. The new circuit can handle more current, something necessary for some CDI ignitions (like those made by RCExcel) that are being powered by a 2S 8.4 volt Li-Po battery.
Electric Retract & Gear Door Sequencer -Another new design, our door sequencer is now compatible (thanks Steve!) with the electric retracts that come pre-installed in many ARFs made by FMS.
We're beginning to get some orders from modelers who build other kinds of R/C models, like boats and ships. Recently, a good customer in Pennsylvania (Hey Jerry!) inquired about a circuit to control a brushed DC motor used on his incredible model of the USS Missouri (BB-63/The Mighty Mo!) to turn the main gun turrets and raise/lower the anchors. Previously he had been using a mixture of toggle switches, servos, relays, and diodes to control these motors, but we designed him a small and easy-to-install circuit to replace it all. Our Brushed DC Motor Controller might be just what you need for your model. And we can customize it, too!
