Thanks David.
I hope that some people have to try a little bit more time to make some better photo's or video's from there works.
What I mean is don,t post every photo and video's you take, only the sharp one.
For example two photo's, and i no who's take the sharp picture, he have a very cheap and small camera, but take's his time to makes his pictures.

RC crawlers are much slower but your point still stands in that they are more capable (and more expensive) than the Lego crawler. But so what? If you're into RC then buy RC. If you're into Lego then buy lego. If you're into both then but it anyway to see how both of your hobbies come together.
I have a scale ish crawler for outdoors, and a mini rock crawler for indoors, but when I saw this Lego set it was an instant must-buy

Much, much more expensive. When I quit I had about $10,000 worth of tools and parts just for RC, on top of a standard home workshop. By comparison, building a bicycle is trivial and cheap. Plus Lego is much cleaner and easier to tidy up from, as well as less toxic and cheaper to run. The advantages are numerous. But I would say that, since I've made to switch *to* Lego.
Now that I'm building the set, does it bug anyone else that there are so many places they could have said "2x" or "4x", rather than just spamming out 10 pages of instructions twice. It looks to me as though the front and rear wheel assemblies are identical, making the second copy of those instructions a bit of a waste of my time and their paper.

I was unfortunate enough to buy general puprose batteries for it. On the second day of not so intensive usage, the speed and crawling ability of 9398 decreased greatly. Compared to relatively fresh 8109 battery box, the motors ran slow and were easy to stall.
Last night I tested the battery and what was left of it's charge to see how it's torque and speed will decrease over time. It lasted for about 1,5 hours before being completely unable to turn two PF L motors.
So yeah, voltage affects not just rotation speed, but torque too.
Thus, one should keep in mind what energy elements to choose.
9V standart batteries or 7,2V rechargeables?
What's your opinion?

but as soon as I can ill buy the rechargeable battery box .. too bad its kinda expensive,anybody knows the reason?
and the 50$ don't even include a transformer ...

Do a research first.
What I've learned so far: rarely do rechargeables live up to these numbers. And even if they do, high number of mAh doesn't mean high Watts per hour or energy they can accumulate. There are many characteristics for batteries apart from mAh. Like internal electrical resistance, self-discharge rate, ability to hold high voltage over certain periods of usage...
Sanyo Eneloop are the best choice it seems. Top Japanese quality. Unfortunately we don't have those in Russia.
What boggers me is why there no 1,5V rechargeables.
As for LEGO battery box, don't know. Maybe it has something to do with low weight. But it's not like it's space or nano tech. And the DC transformer for $25? Nah, the reason is simple. To milk customers.

I think I'll stop at rechargeable Ni-Mh batteries.
