I don't know as we only recommend using genuine Spektrum receivers with Spektrum radio systems. The LSR-3000 will be compatible with the SR300, SR3000, SR3001, SR3500 and SR3300T as those are DSM receivers. It is not compatible with DSM2-equipped receivers.
@latexink I guess the assumption is that you have reverse disabled and the ESC set for Forward-Brake only. You make a great point though, if you have reverse then setting to neutral would be a better choice.
If there's a problem with your gear Product Support really needs to see it first-hand to test, verify and replicate the issues to try to come up with a proper solution. As I mentioned I have seen many people race with the RTR radio and receiver without issue, but without seeing your gear I don't know what it could be.
@crazybearrc Simply hook everything up as you would normally and, before turning the ESC on or connecting the battery, plug the bind plug into the bind port. From here, turn on the ESC. The LED on the receiver should begin to flash. Once it's flashing put your radio into the bind mode and it should work without a problem.
Johnny, all Spektrum transmitters are on the 2.4GHz band. Every time you power up it changes to a different channel after scanning the band for an open one.
Thank You for that answer.. I noticed that there were some brown id numbers in my frequency settings.. No biggy.. I went 2.4GHZ across the board.. Guess that was a correct choice :D.. I have a new small issue today now that I've done the complete strip and rebuild. Is the LED light on the SR3300T supposed to be on? Mine is yellow.. This is how I have my receiver set up so far.. I have my 6v, 5cell, 5100mah Nimh battery plugged in the BND/RS port. I have my steering in the steering port and throttle in the throttle port. I have my RPM sensor in the RPM port. My temp and lap ports are open. I have the sensors but haven't installed them yet. My aux is open as well. I am getting my truck ready for this season's opener in Tillsonburg, On. for the Canadian 5ifth scale SuperCross Nationals starting the 16th of April, 2015.. I will be installing a MYLAPS RC4 Hybrid transponder on my truck as well and was wondering how to correctly install that since the lap port is regulated at 3.5 volts, would I just plug the transponder in the aux port? Thank You again ..
I have a DX4C Transmitter and I am trying to bind it to a sr201 receiver. But it will not bind at all. The light on the receiver will flash like its supposed to while in bind but when I go to bind on the transmitter the light just goes out and will not bind at all. Please help a guy out been trying this for 2 days now and nothing.
It wouldn't hurt to try but it should work as I have seen many people race with the RTR Transmitter and SR300 receiver. You might want to give product support a call and see if they can help you out.
You can only use air transmitters with air receivers and surface receivers with surface transmitters. The only exception is the Marine receivers which can be used with Marine-compatible surface or air transmitters.
@squirrelkiller247 1) Plug the bind plug into the receiver 2) Power up the receiver with the transmitter off 3) Once the receiver LED begins to flash rapidly power the transmitter on 4) Binding should be complete in 5-10 seconds.
3 I'd recommend. The DX3S comes with the telemetry-equipped receiver out-of the box and is the lowest price of these three I'll mention. The DX4S is our newest radio and includes the new DSMR Protocol. The tried-and-true DX3R PRO will be the most responsive radio out of these three. Now the DX4S and DX3R PRO do not include the SR3300T telemetry-equipped receiver so that would be an additional cost.
dunno if you guys gives a damn but if you guys are stoned like me during the covid times then you can stream pretty much all the new movies and series on instaflixxer. Have been watching with my gf for the last few months :)
It's a Trackstar 45a ESC. Thanks for your reply, but I got it to work today :D For some reason I just had to stand around 5meters away from my car and put my DX3C behind my back lol. All my TX settings were neutral, I just had to distance my self away from the car. Who woulda thunk it :P
@hbthebajabasher Failsafe is set when you bind the receiver to the transmitter. So let's say you have a nitro truck. After you go through and have your steering and throttle trims set properly, your servo reversing is set, etc, go and re-bind your vehicle while holding full brake. What this does is if you happen to lose signal it will drive the throttle servo to the full-brake position, bringing you to a stop.
Any surface receiver with Spektrum DSM, DSM2 or Marine technology. The only 2 "surface" receivers that the DX3R PRO won't work with is the SR410 from the DX4S and the old "Bot" receiver, BR6000.
@crazybearrc Couple things. First instead of cutting the receiver's case you should have removed the tab on the plug itself. That would have been the optimal solution. You can use a receiver pack to power the receiver during the binding process if you'd like otherwise just use the ESC.
If you're using a DX3R (or one of the new SPM3140 DX3S' or sent yours in for upgrading) I would use an SR3520. If you don't have one of those radios then you can only use the SR3500.

I bought a new HH Sukhoi su-29mm gen 2 Help - when I plug in my battery no lights come on the ar636 receiver. this is for a Sukhoi su-29mm gen 2, I get 1 tone then 3 beeps a cherp and a wiggle on the prop but no lights on the receiver and can't get it to connect and tried to bind again with bind plug but no lights and no response.
Do you have the RTR Ascender that came with a separate radio system? Or are you looking to re-bind the system? The stock transmitter comes pre-bound to the receiver in the RTR.

Hello,I have a Losi 1/24 SCT brushless,I can install it on this car?,what should it do?,serves Losi MTX Pro Spektrum SR201 DSM 2.4ghz 2ch RC Radio System,thanks.
I'm 13 and need help with my MRX-3000 reciever. I recently upgraded to a Castle Creations Mamba Max 2200kv motor and ESC for a 1/8 vehicle and my transmitter and receiver suddenly have a dratically shortened signal. Im lucky to get about 5m befor the car looses all signal and rolls away. I have no income because Im not old enought to work and I love the reciever and transmiter alot. I tried Rebinding but with no luck. I tried putting in fresh battries, no luck.
When i turn on transmitter then rc car with battery fully charged, the transmitter sort of connects (Red light on receiver stays solid red) to the receiver. However no movement takes place when i push the throttle or turn the wheel.

I have a losi 2.4 dsm with a mrx 3000. I don't understand my battery bind plug, when I plug it in it the reciever doesn't light up. Do I need my regular battery plugged in?
The Bind Plug is not a battery in-and-of-itself, it simply places the receiver into bind mode when attached. You'll still need to plug in a receiver pack or your ESC for power.
If the steering works then the transmitter and receiver are bound to each other. Check to make sure the ESC is calibrated to the transmitter by going through the transmitter setup process.
You have the steering servo and ESC plugged into the wrong channels. The steering should go into Channel 1 or the channel labeled S and throttle goes into channel 2 or the channel labeled T.
I don't know as we only recommend using genuine Spektrum receivers with Spektrum radio systems. The LSR-3000 will be compatible with the SR300, SR3000, SR3001, SR3500 and SR3300T as those are DSM receivers. It is not compatible with DSM2-equipped receivers.
Great move in my opinion. That's what I've been using in my T-28 and it works great!

@Raiden Patrick Yup, have been watching on instaflixxer for months myself =)
@IntoxicatedRebel Plug the bind plug into the bind port and plug the receiver pack into any open slot.
The original DX3R did not have integrated telemetry. However the DX3R PRO does and will work.

The ESC will provide the voltage needed to run the electrical system without the need of a separate receiver pack.
@Nando5966 As long as it has that indicator on it, yes. I have used the SR3100 and SR3520 with the DX3S
@crazybearrc What transmitter and receiver are you using?
Make sure you don't have the polarity of the plugs reversed. I have never had an issue with the 3300T binding to the DX3S
@hbthebajabasher You would basically just not set a failsafe position or the position would be with throttle and steering at neutral
Holy crap...this is EXACTLY what i was looking for- i have dx3s and have an old am i wanna upgrade to something that doesnt glitch!!!
If you're using a DX3R (or one of the new SPM3140 DX3S' or sent yours in for upgrading) I would use an SR3520. If you don't have one of those radios then you can only use the SR3500.
The ESC will provide power to the receiver and the servo.
Thanks, that really sets me in the right direction again, thanks
@aconroy8 You can, just remember though that when you go back to the original vehicle you'll need to rebind and probably reset your trims too.
What transmitter are you trying to bind it to?
What transmitter and receiver are you using?
@Nando5966 As long as it has the DSM2 label on the back yes you can.
Losi Mini-Late Model. I used that since it has a Losi MRX-3000 DSM receiver.

Which Micro are you speaking of? A Losi 1/24-scale or 1/36-scale car or truck? If so then yes it will.
My micro trail trekker wont bind with the transmitter. Do you why?
All of the radios you see there are DSM-only and will not work with crystals.

i went to my local hobby shop and they told me that traxxas esc's dont allow aftermarket transmitters and receivers
awel69 That is absolutely not true! I used to run my DX3R PRO with my spec Traxxas Slash without any issue!
How do I bind to my micro losi with no bind plug port. Just picked up a dx4s
Yes, it can.
You have the steering servo and ESC plugged into the wrong channels. The steering should go into Channel 1 or the channel labeled S and throttle goes into channel 2 or the channel labeled T.
