Yeah, I'm familiar with the AVC function, a friend has it on his drift car.....and I too think it's cheating.

My question is what makes the other receivers different from each other in relation to their functions?....and which one would be best to use? It's hard to commit to making a purchase unless I can find some justification, or NEED.

Anyone run into issues with interference? I had this issue yesterday. My truck kept turning sporadically when I wasn't turning the wheel.

I can´t believe it, the F$%& spring brokes again. Just after 10 minutes of the A-Main. Only 8 hours after repair.

Hate to hear this. Just got my DX4Pro and ran it at the MWS race in Toledo. It's nitro onroad. Loved the feel and response from this unit. I bound it to a DSM 3100 and it was flawless! I still have to install the DSM-R Rx. It will be even better from what I'm told!

Anyone else experience this?

Does anyone know if you can get smaller wheel options for the dx4r

Is anyone else using traction control? I tried to turn it on but when I do I pull the trigger and get no throttle.

Just got this radio, seems it has firmware 1.3? is that the latest? I couldn't find any info the current (or past) versions

Got this radio after a few years on RC hiatus. Will race with it Sunday. Let everyone know how i like it.

Never use 1.2 volt rechargeable batteries with these. NIZN batteries are 1.6 volts and make a huge difference, $22 shipped off Ebay w/charger.

Hey guys, I've been reading through this thread and a few questions have been answered already, but I've got a few more.

Does this radio have different battery options in the menu? I've got the DX4S and it has options for alkaline, nimh, life and lipo.

How is the battery life on regular, alkaline AAs? I've gotten as much as 37 hours on a set from my DX4S and hadn't hit the low voltage cutoff. I just got nervous.

Can anyone suggest an appropriately sized, quality LiFe pack for this?

Thanks very much for your help!

Interesting fact: my son got in a nasty wreck in his buggy and it ripped the antenna wire out of the SR2000 receiver he's using and it still works perfectly.

Alkalines are fine if changed regularly. I would not let it approach the 5.5 mark when racing. That is why i like the NiZn, but I have only had these for 3 months. They rarely dip below 6 volts, and that would be three weeks of racing. You would need a 6.6 volt 1800 mah or higher life battery. You will also need to remove the battery tray, solder the wires, and add foam. That is why I am using NiZn, less hassle. I have seen Lipo's in these as well, and they are around 8 volts charged, not sure I would try that. Spektrum needs to make a Life kit for these, and they should come standard.

I wish my charger would do the nizn, sounds like what I need.

I don't know about 37 hours but I run alkaline batteries and they work just fine for me, even on outdoor 1/8 scale tracks.

And what is LVC for these anyway?..that's hard to determine since you set the warning buzzer yourself I've run down to under 5v (indoors)
