I feel like I'm being suckered into something here, but I'll bite. Don't all 2.4ghz radios output the same signals? It's the PWM between the receiver and the servo that really matters, isn't it?

Those are excellent questions.

The signals output by 2.4GHz RC transmitters are not the same, but they do all transmit digital information. So in a sense, you are correct if you assert that all 2.4GHz radios are digital. But they can be DSM, FHSS, etc.

However, not all 2.4 GHz transmitters provide features like model memory, displays, exponential response, and other fancy functions usually associated with a "digital" radio. At some point the analog positions of the controls have to be converted into the digital world, but it doesn't always happen immediately in the signal chain. A gross example would be an old radio with one of the original Spektrum DSM transmitter modules plugged in. I would still call that an analog radio, though I wouldn't be entirely correct.

Nearly all RC receivers send PWM (which is an analog signal) to the servo(s) and ESC. Generally, digital systems can transmit the PWM signal more often (a.k.a. "higher frame rate") than analog receivers. As eR1c pointed out, analog servos aren't always happy with these higher rates.

Buttons and beeps scream out "DIGITAL"! But let us know what it is anyway.

I have a strange question I am looking to get a new set of tires for my M05 version 1, and Tamiya shows two different size treaded tires. One is a tall tire and the other is a smaller profile. Can someone help me figure out what the different is? I found the part numbers.

PN#50684 M-Chassis 60D M-Grip Radial Tires; SP - 684
PN#50568 M-Chassis Radial Tires; SP - 568

Guys, a Buddy of mine is selling his M05
Here is the link for it, it includes pics also!

The outer diameter. 50568 is a 55mm where as the 60D is 60mm diameter.

Also the compound is different. If you want 55mm, check out the Shimizu's.

Are you running indoors, or out? If you're running outside, a 60d tire will give you a little more ground clearance. If you're running indoors or on glassy smooth surfaces, 55d tires would be okay.

-also keep in mind that the taller 60d tires will give your M05 a bit more top end speed as the tire diameter is taller. However if your using it for parking lot fun this would be a non issue ...yet the taller ground clearance like MonkeyRacing pointed out would be beneficial for rougher / bumpy surfaces.

The radio is an Acoms technisport 2.4G. Pretty sure it's digital

Agreed.

Hey what can you do to the gears to an M05 to make them faster than stock?

I am running indoors on carpet. I really need some good recommendations for tires to run on carpet.

The standard tire for carpet and top speed is the Tamiya 60d S Grip (not super grip, that's something different). The traction is great, but tire wear is insane, especially if you're racing with a locked up diff. I've been hearing good things about the M Grips lately.

You can get better handling, but less top end with a 55d tire, like Sweep or Shimizu. Sweep pre mounts are available through TQ RC at a decent price and last much longer than S Grips. Shimizu "Dunlops" are best bought at Banzai Hobby. In both cases, you'd want to run a soft tire on the rear and a medium/firm in the front.

That's interesting about diameters, we are stuck with the standard gearing and I feel my car is handling well, not losing much speed in the corners (I basically am on full throttle the whole time) I wonder if going to a taller tyre will gain me much. Very large track.

I'm using sweep 33 on the front and 25 on the back
