Out of the box, my NSX-R was fully charged. When you turn on the car, the headlights go on as well. it stays on no matter what. And it's very bright! The brake lights blink on and off.
Once you turn on the controller, it syncs with the car, and the brake lights stay on permanent. Hitting the gas, the brake lights go off.
Once I adjusted the steering trim (which wasn't much) the car stays straight all the time. No need to adjust it at all, no matter what I put the car through. Carpet, launching off the desk down to the floor by accident, and so on. I got a Cox Beetle also, and
I have to adjust the steering avery few minutes.
The front wheels of the NSX-R seem to be the same as the standard DigiQ's, but it's a lot easier to steer than the Beetle.
Turns are smoother.
When the batteries start dying, the car just stops. But the headlights stay on strong. I haven't let the car sit there until the lights die out, so I might do that if someone wants to know the result.
The NSX-R runs even longer than the Cox Beetle. I haven't timed it by my watch yet, but it runs a few minutes more than the standard Beetle.
There's NO SCREW! Yep, you can just take the NSX-R apart! My Beetle on the other hand has one of those custom screws.
The lights are very useful when the car goes far away, or if you're in a dimly lit area. You can use the headlights and brakelights as guides for steering the car. In a titally dark room, the lights don't do much because you can see where you're driving, really.
I'm sold on the NSX-R, and I'm looking forward to getting either the RX-7 or the Trueno with real turning front wheels. I don't regret paying extra for the NSX-R. The Beetle is OK, but if I had the choice again, I would have sprung for another R type car instead. The NSX-R just seems better in a lot of small ways.
Hopefully the next generation of DigiQs will all be improved, and not just limited to these pricier R versions.
If you're debating about getting the NSX-R, I hope you do get it. It's really a blast
