The FX668T is a VTX for those who race drones. It’s small and light,ย but most importantly supports RaceBand frequncies and has a Pit Mode. Theย Pit Mode letsย you disable the RF output on the transmitter at the push of a button.ย That way you do not interfere with other pilots when working on your racer out in the field. Theย FX668Tย has 40 channels including the new Raceband frequencies, which allows more racers to fly together on the same band.
With the FX668T wiring couldn’t be easier, it isย directly compatible with 3-4S LiPO and features aย handy 5volt regulator for powering a FPV camera, so no regulator required. Furthermore it utilises a locking cable, so there’s no chance of it coming out of place in flight.
Last but not least in terms of features, theย FX668Tย also hasย an onboard microphone. This might sound like a pointless feature to many, but there are benefits to be had from being able to hear what the motors are doing (check out thisย blog post), indeed some of the top racers areย using mics to go even faster.
Models
There are three transmitters within the FX668Tย series range, each with a different power output:
25mW FX668T:ย This is a UK legal transmitter, itโs 25mW power output and 27 channels are free to use in the UK without a license. Although you have probably seen more powerful FPV transmitters, don’t think it has a poor range because of its low power rating. With the stock antenna you can get 200m in open space. However, if you are using some circular polarised antennas, you can easily get >300m. Low power FPV transmitters are also really good for indoor environments, where high-powered transmitter often cause multipathing (poor signal quality caused by the signal being reflected by obstacles).
200mW FX668T:ย 200mW is a power output used by a lot of FPVย mini quad racers. It’s enough to provide a decent range and reception and equally won’t kibosh everyone elseโs fun, or eat into your battery life.
600mW FX668T:ย This transmitter certainly packs the power; 600mW is enough for 1km+ LOS long-range flights.
All of the transmitters operate across multiple frequencies and channel bands, including the newer ‘RaceBand’, making them compatible with most FPV gear on the market. Best still, thereโs not a dipswitch in sight, it has a channel selection button and LED light display that makes changing channels a painless experience. The RED LED indicates the Channel frequency selection, the Blue LED indicates the Band selection.
Frequency Selection:ย Single push to change CH, push and hold for 2 seconds to change FR
RF Power Output: Press the button for 5 or more seconds until the LED indicates the VTX is on/off
Unique on/off feature allows the VTX to be switched off while selectingย frequencies or working in the pits (Pit Mode)
Micro size and very light weight
25 / 200 / 600 mWย power options
Standard SMAย antenna connector compatible withย ImmersionRC/Fatshark
40 Channels with RaceBand – Perfect for FPV racers
