I took a lil break for about 8 months and Im looking to get ready for 2013. I owned a Losi 22, DEX210, and B4.1 Worlds. I really liked the DEX210 but at the time it was hard to find parts for the car, traction was great, steering was good slight push on power, pain in the a$$ to work on when club racing.
So I sold it and got a losi, what a bad idea...lol..Sold the losi and got a B4.1 Worlds..Wow I was instantly faster with this car added Kyosho BB springs and was really happy...Then I took break and sold the kit. I never got around to trying the K-Cars but I am considering a RB6. How does this car compare to the B4.1 Worlds? Is the kit that good to carry a $450 price tag?

they coulda sold it for $550 and i would have bought it after driving one.. and RC is a budgeted hobby for me.

its easy to work on, traction is great on/off power. haven't broken a single part (knock on wood) and i continue to beat on it.

and will turn inside any car on the track

I keep a tiny "L" shaped allen wrench in my pit just for this. I slide the short end of the allen into the hole in the outdrive, and you tighten or loosen the diff by turning the right wheel.

cheers guys!

You are right as I first saw them on his site. I also wanted to showcase others build as well as I had to use them as a reference as well when building the front end of my car.

You can't compare the RB6 to the Losi22,DEX210 or the B4.1, it's in a league of its own.

I priced a mid motor conversion (since the kit already has parts) around 200$ from speedtech. They have some parts missing out of stock. So next is to update the ol WC up to spec in mid motor.

The most important was the rear outer hinge pins which have those two m3 nylocs at the end. I can bypass by just going with rb5 rear arms though. Thats about the only thing I hate on the rb6, that and the body hehehe which is next to nothing compared to other cars I have owned.

I have 475 ptrc and 425 ptrc front and back with stockers. That is around 42 37.5 I believe converted to AE wts. I just ran her last sat for the first time. I will get the 1.3 pistons in another set of shocks to try those out with lighter oils.
