I’ll be going analogue and running a 2G4 TBS VTX for long range.
Translation
2G4 2.4GHz video frequency, most quad racers use 5.8GHz (5G8) 2G4 has greater penetration through trees, hills etc. which results in longer range
TBS - Team Black Sheep who were the leaders a few years back in long range flying, if you have heard of a guy called ‘Trappy’ he’s the beains behind TBS
VTX Video transmitter, the unit that sits on the quad and sends the camera image and the flight details (OSD - On Screen Display) to the ground.
This FR7 is actually an open-source design
CNC files are freely availableso if you know somebody with a really good CNC router with really good dust extraction in the UK you can get your own made.
Translation
The battery (or lipo) comes in multiples of cells - 1s, 2s, 3s etc.
1s = 3.7v
The more the cells, the more the voltage, more power (generally). But they are heavier.
The lipo size that you intend to use will dictate what other parts, eg motors, controller etc that you will be able to use safely. They will be rated for certain lipo voltages.
The mah is its capacity. More mah (milliamp hours) means a longer flight time, but again, the larger the mah, the heavier the lipo is.
Translation
Lipo batteries are lithium polymer. Li-ion batteries are made from lithium and erm ions
Lipo batteries can produce a high current output for quick acceleration etc.
Li-ion batteries wont supply as much current, but are more energy dense. Pound for pound, their mah is larger, so the flight time is longer.
Lmao you bunch of smart arses
When I said I don’t understand your FPV language I wasn’t talking about batteries and general tech talk lol Its all the FPV specific abbreviations stitched together like below
Connection loss between radio transmitter and the quad.
A transmission protocol linking the the radio transmitter to the quad.
Receiver to receive the stick commands and any other information sent from the radio.
Think of a UART as a flight controller’s (the main circuit board of the quad) USB ports you solder peripherals to them like GPS units RX’s all sorts of different things can use a UART.
Is a type of Crossfire RX (really small )
TBS is the brand (Team Black Sheep) Unify Pro32 Nano is the model and size of the video transmitter
TinyLED’s is the brand and a Sled is a mounting circuit board where you solder a board into a board:
