whats the difference, between..

the diff between a regular transmitter and a 200$ one or more , what do they do more than a regular one that comes with the truck.very curious.

It's going to depend specifically on the brand and model. Usually, entry level tx's will have simple controls. Throttle/brake. Steering (obviously). Then trim for both those channels. And maybe dual rate if you're lucky. On high end radios, you'll probably end up with a third channel that can be used for things like reverse or other extras. You'll get finer dual rates. End-point adjustment. Exponential controls. And possibly more depending on the tx. These allow you to fine tune the function of the radio to suit your car. And also fine tune the function of the car to suit the track.

it depends. Most transmitters that come with the truck are AM band, a lot of times 27mhz. 27 mhz is bad for interference since CB radio is on the same band in the US. AM, anyway, is prone to interference. Usually with a more pricey radio you will get FM (frequency modulation, much more secure), multiple model setups, charging ability for the batteries, end point adjustments, dual rates, synthesized (versus using crystals for freq) etc. Also, some of the near $200 or more radios are 2.4 ghz, spread spectrum or frequency hopping so they, in theory, cannot have glitches related to interference.
A basic radio will work, it's just that you do get more when you pay a premium amount for a radio set.

Most RTR transmiters only have throttle/brake trims, and servo reversing. What you get with a higher end transmitter is more adjustments such as EPA, dual rate, T/B exponential, servo speed, channel mixing, subtrim, ABS braking, throttle deadband, and idle up to name a few.

wow! so there is quit a difference than running a stock transmitter. i am purely basher but was always curious to know why people have these big ass transmitters. so i guess if you race it would be a good buy then. but for bashing , do you think it would be a good idea?

as an insurance reason for your truck i would say why not. nicer tx's especially the ones that hop frequencies, will nearly eliminate any interferance that can send your truck careening into your neighbors garage and damaging his car (been there, done that, not fun) failsafes also help, but I've seen a couple of them malfunction (probably do to user error). the way i see it is anything to keep the truck safe and to save me money in the long run is worth it.

The adjustment that is critical for servo durability is EPA or end point adjustment, especially when used with digital servos. EPA limits the range of servo travel and can help prevent burning out a digital servo due to overtravel. I set mine to 3-5% under the maximum allowable mechanical travel of the servo linkages, so that there is some give during a crash.

The rest of the adjustments are just bells and whistles for a basher.

thanks alot for all the great info and knowledge, but i thnk i will stick to my stock radio since i wont be doing any racing in the near futur, and since there arent really any rc clubs around here , (damnit), but you guys give some great advice and info , thanks

high end radio's would have more features, like EPA settings etc etc. Also would have more channels, for reverse or something. With some models (like specktrum) they even eliminate the use of crystals, they use a very high digital frequency, they scan for a available channel (not being used with-in range of your remote)and lock onto it, not allowing other digital remotes to use it. This makes running your car an auwful lot safer as there is no interference from other radio's and these systems are glitch free
