Radio systems. HELP ME CHOOSE
 

Hey Guys,
I need a two channel radio system for the E-Revo. I want something decent but not to crazy price range. This is for a customer whos new to the hobby so I want something he'll be able to work and use.

I figure around $100-200

Please help me out.

I was looking at this
Airtronics MX-3S 3-Channel FM/1 94102Z Servo 75MHz

The one you showed is a great beginner model, and it is glitch free. But id reccomend a Spektrum DX3, but if you want the "ultimate" beginner radio than use a traxxas TQ3, they arent THAT bad.

I like the futube 3 pm. I like the hitec agressor srx. The srx can be upgraded to the spektrum to. There is one catch I have found to a spektrum system. It wants to run wide open reverse for a sec on first plugged up. I know most I have named are 3 channel. If they get another rc with a 3 channel stuff only need the receiver to work.

I can vouch for the Spektrum DX3. It has been glitch free and has a nice range of features for the relatively low $250 pricetag. The built-in failsafe and absence of crystals is nice too - no worries about someone else on your band.

Futaba 3PM is a nice radio with all of the adjustments, but not all of the price, 120.00

I have an Airtronics MX-3 and love it. Its got a decent amount of options and a great price. I got mine brand new off ebay with rx and two servos with crystals for under $80. Since you have some more money than that you could go for the MX-3S. If you can, go for the Spektrum as I haven't heard anything but great stories from the owners.

I've been using a MX-3 (75mhz FM, non-synthesized) for over a year now, and am completely satisfied with it. The main thing I need is enpoint adjustment, battery voltage indicator, multiple model memories, and digital trims. This has that and more!

I don't know the features of the DX-3, but I'd go for that if I could afford it, since it is on the 2.4ghz frequency and doesn't use crystals (no-hassle!).

I would go with the spektrum DX-3. I use it with my e-maxx, t-maxx and micro rs4. I love the lack of crystals and built in fail safe. I am not sure if they are still available but they were offering a free extra RX total of 2 with the radio. The radio is real easy on the newbie, and the only drawback is the 3 model memory.

MX-3 it is. Thanks guys

ive always had good luck with jr radios if you havent bought that mx-3 yet.

yeah same here i have the xs3 pro and it is awesome.

I think as long as you get a after market that is not to cheap you good to go. I tried a jr syntheised and liked it. It was not mine though.

Like Metalman said, its only important to have endpoint adjustments, battery voltage, etc etc. But i like my radios to have a great feel too, dont wanna bash when your controller is made of rock;)

DX3 is great for $250, but RcBro's asked for a 2 channel radio in the $100-$200 range. Therefore surely it makes sense that the DX2 would be a better option than the DX3........as its only 2 channel and costs $170 and still has all the features of the DX3.

That is why I suggesteded a futuba or hitec with the modul. It is in the price range and can be updated to the spektrum at later time if choose.

newb quest......?


whats really the difference in radio controlers???

dont they all do the same thing, let you drive the car......

ok, some have digital readouts on them for battery performance and lap times, but who really needs that stuff unless your flying and need to pay attention to your battery life to not crash a plane or heli ????

some take AA batteries, some take a rechargable pack i think right?

so whats really the advantages of this, and dont you need to get a new reciever inside the car then too?

i've always thought that you could use the same controller for multiple cars, as long as you change the crystals when you change cars, am i right or wrong about this?

i need to know because with as much as im upgrading my t-maxx and stampede BL (eventually), will i have to upgrade to a high performance controller too?

Well the model memory is good for different cars. You don't need to change crystals if they are the same frequency. When you change cars you need or have different center for steering and shifing. You can adjust the end points on the better controllers as well for shifing steering and throttle. Helps control truck more if you cut the throttle back some. If you buy one and drive it for little bit. You won't want to go back to stock.

so if i "eventually" dicide to go that route also, can i still use the stock traxxas reciever in the truck, or does that need upgraded also?

Unlikely. The stock TQ3 reciever is 27MHz AM. Most aftermarket radio systems will be either 40MHz or 75MHz, and the spektrum's are 2.4GHz. Plus any aftermarket radio system worth buying will work on FM as opposed to AM. Lastly, most aftermarket radio's are synthesized, whereas the stock radio uses crystals.

So basically, if you plan on buying any half decent radio system the stock reciever won't work.

good to know, thanks maxxdude

not to mention all the good ones have thinks like adjustable epa, ext, dual rate steering, ect. many of which are useful with brushless. for example, i have to use brake epa on my radio to tame my brakes because on my 9920 there are REALLY strong.
