I'm in need of a radio upgrade. I'm getting to the point of my R/C racing that I'm starting to become pretty competitive in the A-mains of my respective classes.

Currently using a Traxxas 2.4 TQ radio/rx. I know, I know...

So I'm looking at the Airtronics MT4 and the MX-V. The MX-V really has all the options I think I need, and the price is DEADLY! MX-V honestly seems to have more features than I'll ever use. I see guys at my track with the MT4, and admit that they don't need all the features.

So, curious what others think...

Honestly, price isn't an issue. I just don't want to pay for a Cadillac if I love driving a Toyota.

I use an mx-v. It was my upgrade from a spectrum dx3c. The features it has do pretty much everything you will ever need. For the price, it can't be beat! It's super light so you won't get tired holding it, but the grip feels too small and cheap. What I did was wrap the grip with lizard skin bicycle handle bar tape. I made the bumps from the overlap of the tape fit my fingers and now it's the perfect size grip and it's ridiculously comfortable to hold in my hand.
I'll recommend this to everyone looking for a new radio. You get airtronics/sanwa reliability with an amazing price point. It also uses the least expensive receivers they have.
That being said, I would still have an mt-4 if it was the right price. Or if I found a good deal on a used one. Just because I know it has better steering and trigger pots and because if I ever decide I need more features than I use now, I'll already have them.

They are both really great radios. I have used the MX-V and it had all the important features you need and it will have a MUCH better response/feel over your rtr radio

There are only a couple things the MT4 has over the cheaper radio imo.. One, the MX-V feels 'cheap' to me. It just does, not much you can do to change it.. Also, the MT4 has telemetry so you get the temperature gauge which is very nice.

Ultimately, if you don't mind the cheaper feel (toyota) then there aren't really any important reasons to upgrade to the radio that costs twice as much (cadillac's are gross so I'll say BMW )

Guess the MT-4 has lower latency than the MX-V.

Yes the latency is higher in the mx-v, but it uses fhss2 receivers and it's not that slow. It feels like an m11x in that respect, which people still feel is an excellent radio.
Considering this person is currently using a Traxxas rtr remote, I think they will be extremely happy with the "Toyota"

If price isn't an option, go with an mt4 and be done with it. Its a professional level radio at a consumer level price.

One of the best rc purchases I've made was a good radio and I love my mt4. Dont skimp on the radio if you've got the cash for it.

If you buy a mx-v you will eventual want to upgrade to a mt4 or M12...

Coming from a guy who has the MX-V, I agree with the posts above. If money is no option, an MT-4 or M12 is recommended. However, if you just dont feel like spending the cash, get the MX-V. If you feel like upgrading to the MT-4 or M12 later, the MX-V will be a very good back up radio and you wont have to switch receivers to do it.

This is what I was talking about with the handle bar tape:

MT-4 would be for you the future racer. Things I use all the time on MT-4.

I turn off certain buttons/trims on my radio for each channel so I don't accidentaly adjust one, servo speed for nitro is great esp on the throttle, 5 step and one step trimming, using different receivers with different response-my on road stuff has a faster recvr than my off-roads, telemetry is good but I dont really use it but the telemetry rcvrs lets me know when my car battery is going low and beeps even when I shut off the car first the radio will beep and tell me a low volt hit, radio will also tell you it's on and no one is operating it if longer than that is will go to sleep mode till you operate again.

This makes it a spectacular radio for overall grip and feel, you won't be disappointed.

So like I have said, I've owned the MX-V and enjoyed its features and how little money it cost me and everything, but this morning my MT-4 came in the mail… and… It just feels so much better and it doesn't have that cheap 'you paid $90 for this radio' feel.. It has a super fast connection! I did some out-of-the-car servo play with it and it literally felt like the servo was functioning-on-my-brain-waves fast! The menu is more than twice the size of the MX-V's and it was very clear and easy to use. If money doesn't matter, I reiterate my previous comment that you should go with the MT-4, and I do it with MUCH more sincerity this time

The mt4 has the pixel screen, just feels better quality too.

I own both, use both everyday at the track. Mt4 for scte, mxv for 22-4. There is no noticeable difference between the speeds. When I'm using mxv, I'm not ever thinking "boy I wish this radio had faster response time". It comes down to whether you want telemetry, and whether money is an issue. The mxv feels a little cheaper than the mt4, but that's because its 80 and not 200

Telemetry

I completely agree here. You can use the 92524 receivers (FHSS-2) with the MT4 and basically run on the "slower latency" speeds. However, I've used both the high speed receivers (RX-461, which runs on FHSS-3, super low latency) and the 92524 (which has higher latency) and I couldn't tell the difference between either receiver and this is both in the same car as well.

The 92524 receivers are excellent for keeping costs down. One thing to note though, is that if you're running high powered servos (I'm running Savox,) that the 92524 receivers are a bit underpowered and you'll need a receiver cap to prevent glitching and brown outs. I've had no problems with the RX461s though.

I use the MT-4 as well, only had it a couple months but glad I got it, great quality, easy to use & great functions. I wasn't to worried about half the function when using a crappy radio, didn't have them & had never used them but once I started using the MT4 I wondered why I didn't upgrade sooner.
Things like throttle & steering curve to adjust how they work, first 50% of my throttle opens at half the speed then the last 50% opens faster, makes low speed throttle application much easier, specially with engines that have lots of low down power, it works similar with the steering to I think, haven't tried it.
Anti lock brakes should work alright to, it pulses the brakes on & off at a pre determined brake percentage, reducing brake lock up.
Some features you may think you won't use but when you see how they help then its worth having them. The MT 4 is great value, there's no backlit screen though, not that its really needed but is good to have, the new MT4s has a backlight.
