I've been in this hobby since january. I've bought a total of 8 cars and batteries and tires and everything else you can think. The best purchase out of all of it? My radio. I started eith a spektrum dx3s. Now I own a 4pks futaba. The best benefit a driver has gear wise is the radio. Do not go cheap on a radio. This I've learned from experience above all else.
I'm not saying spend 500 on a radio. But I'd shoot for a mt-4 or 4pls and up.

It can make a huge difference to how connected you feel to the car when every transmitter input creates a near instantaneous reaction in the car, compared to varying degrees of delay with cheaper radios. My friend just changed this year from a 3pk with a spektrum dsm1 module to a 4pks. He constantly tells me that he wishes he had done it sooner.

I noticed a fairly big difference just going from a DX3R to an MT-4. Felt much smoother, more precise and more connected with the MT-4. The difference between my MT-4 and my M12 are minimal though. More just the feel in my hands than anything between those 2.

Is it a bad move for a new racer to buy up a sweet older model cheap , or should they poney up and inverst in the newest stuff to maximize the life span of the investment ? Share your opinions ...
The "Flavor of the Month" crowd will usually be the first one's to brand a car as being "obsolete". That usually has more to do with it not being the latest and greatest than it actually being obsolete.

That being said, you don't want to run too old a car, because then you might have to worry about parts support. Generally though, a good car doesn't just become "bad" when a never version of it comes out.

The only time I can see where a newer model would really make a difference is if you race with a lot of drivers who are of equal skill and they all have newer cars.

Believe it or not, radios do wear out over time. I'm 99% sure your 7yr old radio doesn't feel anything like a new DX3R/pro.

Also, if I remember correctly, airtronics and ko-propo has more national and world titles.

I'm a Futaba fanboi, BTW.

For me, it's really all about degrees.

Just to look at Associated.

How much improvement is the front end geometry changes from the B4 to the B4.2 (that's 4 cars in the mix) is there....1%. Would it be safe to say you would reduce your race time by 1% with the improved geometry/big bore FT shocks up front?

Then look at what 1 crash (for our track, 1 normal crash that requires a marshall will probably add 6 seconds to your lap) which is 6 seconds of a 300 second race. Which is 2%.

So yes, the newer versions of vehicles are improvements, but a guy running a B2 and never crashes against a guy running a B4.2 who crashes 4 times....guess who wins.

I had the DX3R running only dsm2 receivers at "5.5ms". Airtronics felt much better. I don't care who uses Spektrum. I believe 100% that Airtronics is better in every way.

Maybe Drake would be even quicker if he ditched the crappy radio. Most of his sponsors are under the horizon umbrella. He probably has to use it.

Friends don't let friends buy Spektrum.

A good radio has many benefits.

I have several cheaper radios that came with stuff, and one good radio.

The good radio has more precise control (better potentiometer in the steering and throttle, better radio sampling)

The good radio has an LCD screen so that you can actually see what your settings are, compared to something with multifunction dials and blinking lights signifying what you're changing.

The good radio has the ability to plug in a lipo battery, instead of AAs.

Most radios have the important settings.....endpoints, dual-rate, channel reverse. Some have added benefits for helping you learn to drive. My radio has an ABS option, where you can adjust the pulse rhythm and strength. I find that works GREAT for 2wd, both on- and off-road. It can be a help for 4wd as well. I can also turn down the speed of the steering or throttle. I find this a good learning tool, as I often get on the throttle a little too quick. When I turned my throttle speed down, I found I had more control.


Those are just a few things, plus if you are going to be holding the radio for hours and hours and hours, a better feel goes a long way.

i have a two years old rc8be that im thinking of replacing for two reasons,
1. there is an over all wear and its not reasonable to replace every thing.
2. new car= starting the set-up from scratch and have everything smooth.
but, if it was good for the Ryan's, then i can Probably still get better with it

dont know what to do...

That's quite an accomplishment (7 years) since the radio came out in 2008. Human's can't detect the difference between 5ms and 10ms. Average human reflex reaction time is in the 215ms range (mine was closer to 280 on the test below). Try for yourself:

+1 on that! I can't feel the difference in speeds between radios, but I will maintain that Spektrum stuff is crap. Every time I've experienced or seen others experience radio glitches, cutouts, runaways, etc., it's always been Spektrum equipment.

Radios are no different than any of our other equipment. There are differences, some people can feel it, some can not.

wouldnt you add the reaction time ?

brain tells hand in 215ms + radio tells car in 5.5ms =220.5ms opossed to 226.5ms if using 11.5 frame rate ...so yes i do agree and have felt the difference between frame rates and so have other's with thier raaaadio

i guess my radio is holding me back .......but just cuz its old


anyways i guess if you use spektrum new racers your just holding yourself back ....so buy airtronics youll never have a runaway or any other problems

I don't see reaction time coming into play all the time. A planned input to the radio eliminates that. Like when you turn into a long sweeper. There is a video posted on this site somewhere that actually goes through the whole "speed" thing. Granted it's from a European airplane guy but it's relevant non the less.

I'll try to find it..
