Sanwa/Airtronics MT-44 FH4T/FH3 4-Channel 2.4GHz Radio System w/RX-482 Receiver
This is the Sanwa MT-44 FH4T/FH3 4-Channel 2.4GHz Radio System. The MT-44 is the next development for Sanwa offering impressive features in a lightweight and compact transmitter. Most notably, the MT-44 is the first to use low voltage technology as it's power source, using only three "AAA" batteries for power, or an optional 1S LiPo battery. This advancement not only helps reduce overall transmitter weight, but it also helps free up size, space and comfort requirements.
Other worthy features of the MT-44 transmitter include a white backlit HD display, a collapsible handle to provide full view of the LCD, USB charging, telemetry, 1S LiPo capabilities, FH4T and FH3 support.

NOTE: SSL (Sanwa Synchronized Link) System
- SANWA SSL SYSTEM
- When used with compatible RX-472, RX-482, Super Vortex Series, SV-Plus Series, the setting of ESC etc. by Transmitter is available through SSL functions while driving.
- Since the setting can be done without the stop of car, the detailed adjustment in accordance with Race conditions is available without interruption of Intervals and the change of machine conditions.
- RESPONSE OF TELEMETRY SYSTEM
- It is often said that telemetry system reduce response speed. However, SANWA Original Data Processing and Algorithm Design makes Telemetry possible without response speed reduction.
- Sanwa's Excellent Telemetry System has no response speed reduction.
- RESPONSE MODE
- Please do not use Analog Servo for SHR mode or SSR mode. If analog servo is used for SHR mode or SSR mode, the servo will be broken and will not work.
- Digital servo (SRG series, Digital ERG series, SDX series) can be used both for NOR mode and SHR mode.
- SSR mode can be used only by SRG series servo.
- In SHR or SSR mode, BL-RACER, BL-FORCE, BL-SPORT, F2000, F2200, F3000, F3300, SBL-01, SBL-02 and SBL-03CR do not work. Please use NOR mode for the above ESC.
- SV-08, HV-10, HV-12, F2500 can work by NOR/SHR MODE.

The Screen was well lit and easily readable. Like the short cuts that you can do to get straight to some screens on start up of the radio. I haven't yet tried to set up the telemetry so I cannot comment on that yet. All in all, Everyone at the track last night fawning over this thing. If your a serious racer.. This Radio is for you.)
Things to be aware of.
Buy extra batteries, the dry AAA's drain quickly... I cannot wait until the Sanwa 1s lipo is released. 3 AAA batteries make it through 2 race days for 2 classes.
Radio only supports FHS3 and FHS4 receivers. (MT4 supported FHS2,I have several of those))
Very light weight
Menus are much simpler than previous Sanwa/Airtronics radios (compared to M11)
Screen very high resolution and clear
Very fast boot up, including shortcuts to boot directly to the car selection screen.
SUPER comfortable in the hand
Makes me feel like I'm driving with telepathy (it's that smooth/quick)
Native LiPO compatibility, including adjustable low battery alarm
Micro SD Card slot for backing up settings and firmware upgrades.
Telemetry reads receiver voltage without any additional sensors (handy for nitro racing).
Standard wheel position is already where a dropdown would be, no need for a drop down.
Cons: (None of these are deal-breakers for me, just things I think Sanwa could have improved.)
No left-handed option. I don't understand why left handed drivers have to buy the $500+ radio!?!
Included reviver RX-482 doesn't fit in the Associated RC8B3 receiver box. But it's still a great receiver.
No rocker/two-way button on grip for steering D/R. It uses one of the rocker buttons around the rim of the wheel for steering D/R.
Out of the box, it uses AAA batteries. Most rechargeable AAA batteries are 800-900mAh and that is good for a couple hours of use. You will need to recharge those every race day. If you are going to run a long nitro main, you will probably want to top them up before the main. They have a LiPo coming out but it's only 1200mAh. LRP has a 3200mAh LiPo coming out for the MT-44 soon, As far as I'm concerned this is a must have. This radio uses a 1s LiPO so most of the LiPO batteries for radios on the market are not compatible.
Update, after a couple months I still love this radio. I have started using a standard 18650 Li-Ion cell. You can find them almost anywhere, they are used in a lot of LED flashlights, and those E-Cig/Vape contraptions. I bought a Tenergy 2600mAh (P/N 30049) cell for $10 at Frys, soldered a receiver lead to it and it works and fits great, it even has built in voltage cutoff. Just be aware when buying 18650 cells, they come in different voltages. The one I bought is 3.7v Nominal 4.2v when full just like a LiPO, so I can just charge it on my charger as a LiPo. I get several race days between charges (running 1/8 eBuggy and Nitro). I could probably go longer, but I just like to charge every couple race days for the piece of mind.)
Often, It fails to arm when switched on, have to disconect the batery pack and reconect to arm ,
It also loses all memory at times ,have to rebind and reset everything ,real handy when youre race has just been called. Only got it because i had so many sanwa receivers i thought ide save some money, wasted another $400.00au .
UPDATE after many enquirys I found some info on the Sanwa site.
The servo jitters is considered normal because of the fast response time ,and they assure it wont damage the servos, they describe it as frizzing ,fine jittering .
Theres also a software update that should fix all the switching on and resetting issues, as well as many other issues that I wasn't aware of .
Bit of an annoying thing considering its a new radio ! And you need a mini card and a suitable
computer to update the card .
Still they are great radio otherwise. PS i might be able to update my mt4 also, and fix the trim fault ,so i ccan have a reliable spare .
Hope this helps some others who may have issues .SANWA For CarFor Sky All NewsNew productsImportant information Japanese
About the digital servos specification
Model: All "SANWA" brand digital servos.
SANWA's digital servos were designed to improve a vehicle resoponse to the limit. As a result, the servos makes frizzling noise on neutral status and also the servo horn vibrates slightly. These symptoms are caused by the strict specification, however it does not affect product's performance. We would recommend you to feel the deffirence of the vehicle response.)
The adjustable trigger I like most, you can reduce the "play" or finger wiggle room with the various trigger guards and therefore there's reduced delay (more connection) if moving from forward to brake/reverse. The anti lock braking is a pretty cool feature I'm still messing with but it basically works similar to a normal car; modulating the brake inputs off and on.
The interface is easy to navigate and there's plenty to adjust. I haven't compared this to the M12 but I'm struggling to think what more you'd need to justify spending the extra cash. A few forum punters favour the MT44 due to its lighter weight and improved ergonomics and has the same transmission speed.
AAA battery life isn't great and the Sanwa lipo doesn't appear to be available yet. One option, if you're handy with a soldering iron, I used a 18650 lithium ion battery. @ 3400mah @ 4.2v it holds far more than AAA and fits in the tray nicely.
You can feel more connected from the physical and software tuning aspects of the transmitter: reduced play in trigger, smaller steering, better ergonomics, throttle and steering curves etc. But I wouldn't buy this transmitter if you had that in your existing transmitter and you were looking to buy this transmitter just for the claimed faster transmission speeds. Seriously, if anyone can feel the difference of say 3 milliseconds or less (Sanwa vs Futaba et al) then perhaps you would be suited to a career as a super hero or offer your body to NASA for probing... The average punter's reaction time is around 200ms, the world record sits at 100ms, exceptional latency in computer games is 20ms or less. Lets face it, parting with $300 bucks is enough to connect you to your purchase, so I'd say this is more marketing differentiator / purchase reassurance than pure science... Stay connected with your cash and buy this for the more tangible reasons...)
