Spektrum radios are in no way bad, however i have held futaba, airtronics, and spektrum, and the futaba and airtonics seemed to be slightly higher quality the interface seemed to be better too. I could not tell any decernable difference between the performance though. (Futaba 4pl airtroonics mt4 and spektrun dx4s)

I really like the way the DX3S feels, and very light. I race cross handed so I will have to try it first before buying. Too bad dealers don't have merchandise days where you can try their stuff out on the track like golf companies do. RC demo days would be awesome for sure.

Does anyone in the know, know if the optional DX4S Spektrum 2S 2400mAH lipo will work with the new DX4r Pro? The Spektrum site does not list anything for it yet, but I really hope it's the same.

The DX4R Pro is not set up out of the box to use anything other than AA batteries.

Sorry, I understand it comes to use batteries, but the DX4S does as well, are you able to use the same lipo as the DX4S if I have one, or is it exclusivley for AA battery use?

Thanks

Question would be, is it worth it to upgrade from a DX3R Pro? I see slightly different technology, different case color, and some adjustability options.. Not sure thats enough to warrant an upgrade... Thoughts ?

I'd like to know as well. Started my experience with Spektrum with the original DX3 (which despite changing owners a half dozen times is STILL in use today), upgraded to the DX3R when it came out, then the DX3R Pro which I am currently using and love. Never had a single reliability or glitching issue with any of my Spektrum radios regardless of esc, servo, battery, or motor combination. If I knew somebody at the track wanted a used DX3R Pro I'd sell it and buy the new radio. Who knows? Knowing myself I'll probably end up with the new radio anyway.

The DSMR protocol is a fairly big deal and really gives the best and most reliable connection out there today. If you crawl, it has features for you that are a big benefit. But past that, the updated trigger and the updated wheel both with the spring tension made the feel of the radio much better to me, it will be to each of you to decide past that.

So can anyone say for sure that the scroll dial issues have been fixed ? My S radio scroll dial collapsed inside the radio twice , then I paid to upgrade to an R and paid the diferance. Had no issues for about 2-4 years but now my scroll dial does not stup at the mode that I wanna go to. I've been told it may need to be cleaned by sending it back to horizon. I'm thinking just to trade it in and pay for getting the 4R but I got about 6-8 receivers. Will all my receivers work wih this new radio? I've read the thread but there is conflicting opinions on some of my questions. Another issue is that I can only drive left hand radios. I'm gonna try calling horizon to see if they can answer my questions. Its worth saying that the remote that I have been using ( my R) has been the best radio I have ever used, the functions, the feel and the performance as well. Just now for past 4 months the scroll dial has messed me up.

The 3520 receiver will work fine with the DX4R Pro. Used it at the Spektrum race this past weekend in my SCTE 2.0.

Since all the team drivers have the new radio, is Horizon going to release the radio earlier then the December date?

I am currrently using a DX2S and am looking at upgrading. There is a DX4S down at one of the shops I could pickup and get going right away, or should I hold out for the DX4R Pro? Can anyone tell me the main differences? It is hard to tell from the Spektrum website.

I already see the mentioned adjustable trigger and wheel, but anything else?

Picked mine up today.

Left hand conversion is included for those that wondered. Jumbo and std grip.
