I actually guessed the new Ultima buggy would be mid/rear motor interchangable, alum chassis, cab forward. Not surprisingly, it's a bringing together of all the modern successful cars and traits. B4 front tower (or TRF201 front tower!), Losi and Durango chassis and motor layout. What surprised me were the different battery supports built-in. There's also a European flavour to it, a nod to Vega, RudeBits and the LMR wing (the way I see it).

I just got a new Sanwa BRX servo, silly me it won't fit in the RB5, but the extra 2 mm would fit in the RB6. Total cost of ownership-wise, it's already saved me a new servo!

Damnit, I just bought an RB5 WC edition a few months ago too!!

Oh well, I still think my car will still be competitive at my local track since its a really tight, technical indoor track running 17.5.

Can probably see the RB6 doing quite well on rougher, larger outdoor tracks with some mod power.

Along with KO this seems to justify the price.

Perhaps the currency exchange, Yen to Dollar, has something to do with the increase in prices we have seen. Back in 2008 it was close to 120+ Yen for 1 Dollar. Now it is floating around 78 Yen per Dollar if I read the chart on xe.com correctly. Although I am no expert on currency and converting so I could be wrong.

The car looks trick as hell and I am definitely considering it as a replacement for my B4.1 Worlds.

I talked with a few guys locally about the car today and they were complaining and discussing the cost, and saying how it would never sell. These are the same guys who buy a new Xray on-road chassis every year because of the newest "optimizations," and don't wink at almost $1000 for the TKI3.

Kyosho's race kits are premium kits. Are they worth the added price? That's impossible to answer definitively or without bias. I'll give you my experience: I've run Kyosho stuff for the last two years and I almost never break parts. I can't even remember the last time I broke anything on my RB5. I built a B4.1 WC to try out and see what all the fuss was about (plus I collect 2wd buggies to sit on the shelf). No exaggeration: I broke something on the B4.1 during each of the first three battery packs I ran through it (it drove extremely well, btw). Two front arms, front tower, rear U brace, and a turnbuckle. Now, replacing those parts was a lot cheaper than replacing parts on an RB5 - but I NEVER have to do that. So... YMMV

So it's up to you. There are great reasons to buy a premium quality kit at a premium price, there are great reasons to buy a lower priced kit that still races incredibly well. But don't throw a fit because a kit that has far higher build quality and is manufactured in Japan is more expensive than stuff made in China. Just buy what suits you best.
Well said Mr.Downy! as far as kyosho goes....YOU PAY for what you get!

It's simply amazing all the griping about price. Don't buy it. Bam. Go post something useless in the dozen other threads.

Kyosho is always quality. Kyosho is the only cars I've ever bought that had zero missing parts and zero fitment issues. I just bought a 425 dollar DESC410V2 kit that had missing parts and I had to sand the coating off of multiple parts to get fitment correct. But oh well! It happens.

This car steps up the bar for AE and Durango and TLR. I love the changes.

T-Plate gone, and hopefully the axles are different. I broke them also, lol. Several.

I broke more shit on the rb5 than I have since ... my rough rider. But thats a moot point. As for the cost of the car, inconsequential in life, if it's that good then the actual dollar number is pointless. Unfortunately for me from appearances it may not be for me. What I want to know above everything else > HOW AND WHY is this car better than the RB5. The RB5 is a direct descendant of the Ultima RB which ran at the worlds in 1999 so yea it may need replacing.

The RB6 is a completely different beast. I see no reason to think that I'll like it. I'm not much for pandering.

I'm not too thrilled about it.

No more t-plate=no more traction

Looks like a Kyosho 22, no thanks. Pretty soon you'll all be raising your trannies searching for rear grip. Hopefully I'm wrong but only time will tell.

Man, you guys know so much about RC cars that you can tell how well they will perform just by looking at pictures! That's impressive!
