Foxeer TM25 Switcher 25mw/200mw/400mw 5.8Ghz AU FPV transmitter for FPV racing, raceband - 25mw - switchable telecommand - SMA PigTail version - the Foxeer has easy setup via the LED Band/Channel/Pwr indicator
A single LED digit is displayed - digit Number by itself = Channel 1-8 ; short press digit number with Dot = Band 1-5 ; digit flashing dot = power level 1-3 (1= 25mw)
**requires a dB meter DIY
Antenna must ALWAYS BE FITTED - Always fit the matching antenna BEFORE POWER UP - or permanent damage will occur - irreversible
Heat - ensure the Tx is well ventilated at all times - especially when in the workshop - for drone mounting use thermal pads to wick-away heat to a larger surface area of the airframe
FPV code - Always turn on your Goggles first and scan the channels for any live images/pictures from other flyers or users - if the channels are clear - then - Power up your Tx - Make sure you do not cause any interference with other band users.
Power - Increasing output power will also increase input amps/power required and this may exceed your voltage BEC - We recommend 25mw to start - good receiver antenna are the key (as opposed to power) as a good receiver can increase your gain by a factor of 10 - compared to higher power where you have to quadruple the power each time to double the distance which is ineffective in itself. - for higher switcher setting used by Hams - move the Vcc Power in wire direct to the 4s LiPo pads on the PDB. Lower power setting ensure the signal does not cause problems for other FPV pilots - shooting down (swamping) another pilots signal will leave you liable for the cost of his drone damage incurred by your actions - so take care please
