Hiya Bluehills315,

I just bought my rb6 off my lhs, who also happens to sell online.
Racecraftrc
He has a nice selection of parts, with more coming in daily!

He's located in Singapore, awesome dealer.

Shalom and God Bless!

I sold my 22 to get an RB5....Loved the kyosho parts quality, lack of slop and the shocks are super smooth and lack leaking. After a couple of months, I decided to get the RB6. Its the best decision I made.

All I can say is WOW,first time on the track and I was 1+ seconds a lap faster over my RB5. Only problem was the rear bulkhead broke at the ballstud mount after a weird landing.A-Main + UPS 2nd day will fix that. LOL

I have the .5 degree hubs as well as the 1 degree in aluminum but not the 0. I am going to run the stock plastic to see how the 0 feels.
