Okay, lets put this arm thing to rest. It's like this:
The current RDX arms are more fragile than those you find on other touring cars. While we all agree it's preferable to break an arm over bending a bulkhead, it's well-documented that these arms are more fragile than other cars with strong arms that don't bend bulkheads. People can deny this if they want, but deep down they know it's true.
You can mitigate a lot of the trouble with arms by using the SRC bumper (see also: "The Shovel"). The fragile nature of the RDX arms is because of a design compromise more than anything. You see, the arms on ALL 4 CORNERS of the car are exactly the same. Front to back, right to left. It's extremely convenient.
Corally has had aluminum arms available for a long while that are considerably more durable, though most people prefer not to use them for various (good) reasons. Also, Corally will be releasing new arms in the very near future that are designed to be much stronger, and will likely be on par with what you get when using cars from other manufacturers. These arms are not the same from front to back, so you'll lose that convenience, and will need to stock them for both ends of the car. These arms are not intended to replace the current arms (which work fine, and have been used to win a trophy or two in the last two years), but rather, are offered as an option part to people who feel the existing arms are too fragile.
Again, they're both very capable cars, as we've all said a million times. The T2 has a lot of modern conveniences that make it very flexible (some pun intended) for multiple surfaces, and quite easy to work on. It's also going through some growing pains, which is sort of the norm for XRay since they release cars at such an incredible pace.
The RDX has the benefit of nearly two years of refinements under its belt. The RDX you buy today should be called the RDX 1.5, since it's got quite a few upgraded parts from the original kit. It's also managed to remain competitive in the face of at least one (and sometimes 3) major releases from every other touring car manufacturer.
Both cars are expensive, and the parts are expensive as well. If you can find the parts at a dealer (stormer, a/b, speedtech) you'll save a few bucks. Running either of these cars will cost you some cash, especially if you stock your own stuff. These are smaller companies producing cars with a higher production cost in lower quantities. That's how it works for "luxury." Check out the prices of parts before you buy one, otherwise coming here to bitch about the cost will make you look like a dick, as I found out myself. If you're racing on a small budget, go get a nice used Xray FK05 or new Tamiya TA05 with a few hopups. The FK05 is a damn fine car, can be had for cheap, and shouldn't need too many parts since it's fairly durable. The TA05 is cheap, the parts and hopups are cheap, and it's a great performer.
