So I bash some parking lots and race some onroad so I'm thinking of moving from 3pv to dx5c or dx5r is this a bad move would I notice any difference in response time?

Spektrum is inferior to Futaba. Maybe look into some of the Sanwa transmitters if you want to see a difference in response and smoothness.

Spectrum radios rock !!!

no way, thats a downgrade. Futabas customer support alone is worth it. Their performance and fit and finish is better too! Get a 4pv or used 4pls. You wont regret it, as stated before only other radio would be sanwa!

the only way up from futaba is a sanwa, going the other way is a headache.

Spektrum has only caused grief for me in the past, why not go with a better radio in the Futaba lineup? Perhaps having a forward compatible Rx and still keep your old Tx as a backup?

If you already have a futaba radio switching to spektrum will only make you life harder. I forgot my radio at home one day and had to borrow a dx4c. My lap times were off by over a second for fast lap and my consistancy went from a half second spread to a two second spread. It was straight up frustration. We have a local that can somewhat keep up to me that runs a dx4r and savox servos he almost always has radio issues that keep him from winning. Its even frustrating for me to see hom constantly have issues. Altho i got one buddy that runs a 5r and he never has an issue.

I switched from a Futaba 4pv to a Spektrum DX5R a few months back and I've had no issues nor do I regret it. If anything I got faster with it. I know plenty of guys with dx4c radios that are very fast with them. One of them if I remember correctly podiumed at the one turf nationals up in Connecticut with one. To say spektrum is a downgrade is a stretch imo. I also use Savox servos without a glitchbuster and don't have issues

I feel like pricepoint really plays a lot into this too... all $600 radios are going to be more than enough for the average club racer.

$200 and $300 models though.... I noticed a massive difference switching from Spektrum to Futaba in that price range. Futaba, KO Propo, and Sanwa absolutely knock Spektrum out of the park on that one. Their mid range models just seem so much more oriented at racers rather than crawlers/bashers. Not to mention, at least to me, there was a largely noticeable difference in latency between my 4PV and my DX3R, even when using DSM2.

I would recommend borrowing a couple different radios at your club and test driving your friends cars... that will give you an idea of how each radio feels in your hands.

I currently race with Graupner, and don't plan to switch brands anytime soon... folks with smaller hands don't really like Graupner because the trigger has more travel than most other radios. I have fairly large hands so I don't notice this problem. I know Lucas and RJ recently went with the 4PV and they're very happy with that system, which is probably the one I'd pick if I were to decide to ditch Graupner.
