Being new and not really knowning what I needed or wanted in a radio, I just picked up a Futaba 3PM-FM. A guy at my LHS recommended it and at $129, how could I go wrong. It's lightweight, easy to adjust and seems to get the job done. I only have two complaints about the radio; 1) The ATL brake button is located right by the thumb and I have a tendency of accidentally pressing it, so I really have to watch my brakes, otherwise it gets set to zero, and 2) The rubber on the steering wheel keeps moving and binds up against the radio body, so I have to pull it out and reposition it. Both of these problems are very annoying and I find myself having to deal with them even while I'm racing. The ATL brake button alone warrants a radio change. I guess I could always glue the rubber to the wheel.

Initially, I was contemplating getting the Spektrum radio - and quite a number of guys at the track tried to convince me to get it based on the fact that you don't have to fuss with any crystals, but some other guys said the radio is still a bit glitchy. Since there are only a limited number of guys racing, frequency selection is not an issue. The M11 was a canidate as well, but is it really the standard in R/C radios these days?

The only thing I really adjust are the endpoints and the brakes at 50%. I was told that using throttle exponential on a Nitro car is highly unadvisable. Everything else is at 100%.

For servos, I choose the Futaba S9451.

I use an Airtronics M8 with Spectrum. I am going to get an M11 before next indoor season. Dont need it, but it will be nice. I run the Airtronics 94357 servos for steering and throttle in the gas car and 93145 or JR Z3550 in 1/12th. On the carpet I have stayed away from using the Spectrum, but outside, it has worked flawlessly.

I have used Futaba surface radios since I got into the hobby back in 1987. I have used JR back when it was JR Propo and Airtronics, but have has the lease amount of problems and glitch issues with Futaba. I have recently used Hitec with almost the same success. KO has been the major brand that I have not used. I currently use the older 3PDF on my offroad gear and my 3PK on my onroad gear. I have the Spektrum (with mixed results) and the synthesized module (works fantastic) for my 3PK. I use the new Hitec receivers because of the size and price as compaired to the Futaba receivers. But, you really can't go wrong with any of the high-end versions of any of the brand radios on the market now. It just depends on what you prefer and comfort-level.

Before: JR Xr3 w/ Futaba servos. At the time, good price for digital FM radio (still is...)

Now: Hitec CRX w/Spektrum (just came in!). Just because I wanted a Spektrum setup and didn't want to pony up for the M11

I use:
- Airtronics M11-Good Radio(a little heavy) but coming from an M8 which was nothing but good for me.....
-K.O. Propo Servos-Good and Powerfull-They are very Consistent
(I also have airtonics 94257/58(5 or 6 yrs old they are good too...)but will only buy KO servos from now on...
-Spektrum System-Will not go back to FM. (Why??) I have never had a problem with this system. Most important is to keep the Battery charged....

I know a little mixture of everything but they all work well together.....

Default KO Mars-R

I'll only use KO Radios. My actual transmitter is a Mars-R circa 2003, why? because I feel comfortable on it, probably other models can have more bells and whistles, but my trusty Mars is what I want.

My previous radio was too a EX-1 Mars (the old grey AM model bought it around 1991) and got over the years got accustomed to the shape and weight of it.

On servos only go with the best: Futaba servos (945x/9402) mainly.

Spektrum DX3. No glitches, no crystals, no one driving my car into the wall because they start up the radio without a frequency tag.

I heard that the EPA of spektrum radios is lower than regular radios? Meaning no matter how much EPA you set your spektrum radio, it will never reach the servo's maximum... This true?

I haven't found that to be a problem. I had to pull mine back to protect the servos, 1 JR and 1 Futaba.

Futaba 3PJS (cause it has everything , is lightweight , low profile , low battery draw and works with spektrum)
Spektrum DSM (cause I hate crystals at races with idiots. I glitch less on the spektrum so)
Futaba s9451/s9550/s9402 (all work nicely)
Ko Propo pds-763

Spektrum is actually slower. It adds a delay to all radios actually.
