Airtronics MT-4 SSR 2.4 GHz Radio System w/RX-461 FH4T 4-Channel Receiver
Airtronics MT-4 SSR 2.4 GHz Radio System w/RX-461 FH4T 4-Channel Receiver
Derek Rowe - Rating: 5 of 5 Stars! Verified Owner Tuesday, December 27, 2011
I can't get enough of this radio. I love it so much. Here is what I have to say about it: SIGNAL - The MT-4 utilizes the FHSS-4 signal transmission sequence. I am upgrading to this radio from a DX3R (which I paid $400 for when it first came out, and I have had several range problems with it) which uses DSM, or DSSS signal transmission. FHSS and DSSS signal transmission use the same amount of power, but FHSS sends signal across three different frequencies within the selected band (10 (give or take) different frequencies are in a selected band - varies with RC and WiFi) that are constantly changing based on a pseudo-sequence. DSSS signal transmission sends signal along each frequency in the band. Both of the protocols used by FHSS and DSSS signal transmission effectively reduce interference, but FHSS has been proven to be about ten times more effective at avoiding interference than DSSS. Also, because FHSS and DSSS use the same power, but FHSS divides this power usage among 3 signals while DSSS divides power among all ten (or so), FHSS radios typically have a much better range. BUTTONS AND MENUS - The radio has a good number of assignable switches and buttons. It has two buttons, four trim switches (which can be used for more than just trim, but they are labeled on the controller as trim), a lever, and a dial. It also has a scroll wheel and back button. The scroll wheel scrolls smoothly through the menus and instead of scrolling to a back button on the screen like you have to do on the DX3R, all you need to do to go back is press the back button. You can also hold the back button to go all of the way back to the main screen. Another feature I really like about scrolling through the menus is that when you press the scroll button from the main screen the menu pops up on the right hand side of the screen. When you highlight any part of the menu, on the left of the screen a sort of sneak peek of that sub menu shows up, kind of like the preview pane for reading e-mails. Airtronics/Sanwa has also made a very consolidated channel set up screen, where you have dual rate, end point, curve, speed, trim, sub-trim, reversing and fail safe adjustments for all four channel all in one convenient menu. AUX CHANNEL PROGRAMMING - The radio includes five different auxiliary modes: Step Auxiliary, Point Auxiliary (with 6 points - you choose the value of each one), Four Wheel Steering Mixing, Motor On Axle Dual Throttle Mixing, and Auxiliary Mixing (mix the aux channel to steering or throttle). TELEMETRY - The telemetry on this radio system reports signal strength, receiver voltage, two temperatures and a RPM reading back to the radio. I love the telemetry screen on this transmitter. The signal strength and transmitter battery voltage are view-able from the main screen and the telemetry screen. The telemetry screen is sort of like a second page of the main screen. All you need to do to get to it is scroll the wheel down one step. The telemetry screen includes a digital dial that mimics a speedometer gauge, the actual number in mph, kph, or rpm that the car is traveling at at any given time, and the max rpm/mph/kph of the current run (it resets after turning the receiver and transmitter off). There is also a receiver voltage battery bar, the current voltage, and the max voltage that it has reached. The same is true with the two temperature sensors, except that they have an additional feature - a line that marks the user-selected alert voltage. OTHER - This transmitter also includes fully adjustable anti-lock brake programming. This transmitters antenna is also integrated into the handle which is really nice. Also, I just notice that the volume of the beep that you hear while scrolling can be adjusted. SUMMARY - I love every feature that Airtronics/Sanwa has packed into this radio. The only complaint I have heard about it is that it doesn't have a backlight. I don't really mind this because I don't usually drive when it is too dark to see the screen but I'm sure that there are plenty of people who do. Still, the transmitter can be easily set up to alert the user with audible tones when a voltage goes too low or a temperature goes too high. This radio is also an incredible deal and it uses the best (in my opinion) signal transmission mode. It has a nice compact design and includes a loop that you can install so that you can attach a lanyard to it. I also love the ease of use and simple display and organization of the menus. There are so many options with this radio. It will suit every setup nicely.
