Do RC cars use crystals?
In most of our R/C equipment it is a crystal that determines the channel or frequency that the equipment is working on (the exception is equipment with frequency synthesizers like the Hitec Spectra module). With no crystal a transmitter will not transmit at all.
How many channel transmitter do I need?
The minimum we suggest is 6 but ideally 8. When adding in a camera and gimbal to the mix this can quickly grow further (shutter, pan, tilt, roll, gimbal mode, etc). For a single operator setup with camera you would want a minimum of 8 channels for the core functions, and ideally 12+.
How many channels do you need for an RC car?
two channels
Normally an RC car requires two channels, one for steering (ch1) and one for throttle (ch2). However, in most cases, controllers have 3 or 4 channels.
What does PNF mean in RC airplanes?
Plug-N-Fly
PNF stands for Plug-N-Fly. Same thing as PNP. ARF stands for Almost-Ready-to-Fly, this means the model needs some additional “need to complete” items before you can start flying. Common additional items include servo’s, motor, electronics, batteries and even glue.
What does a crystal oscillator do?
Crystal oscillators are used mainly in digital integrated circuits for providing a stable clock signal and in specific applications which require high-frequency reference.
Why are crystals used in electronics?
If you apply an alternating voltage to a crystal, it causes mechanical vibrations. The cut and the size of the quartz crystal determine the resonant frequency of these vibrations or oscillations. Thus, it generates a constant signal.
What does RTF drone mean?
Ready To Fly
RTF stands for Ready To Fly, meaning the drone is completely built, everything included and ready for a basic flight experience right out of the package.
What does plug and play mean in RC planes?
A Plug-N-Play electric rc airplane has the motor, ESC and servos installed but is missing the transmitter, receiver and motor battery pack (& charger). In other words, the airplane comes 99% assembled just like an RTF one does, but you need to supply your own transmitter, receiver and battery pack.
