I think i had the RR on when I put the RF2 on, Might explain why I had no traction on a dry track

Correct except the rr hangers are not labeled and you have to compare the parts to tell which is which.

If it has a step in the back it's the rf/rr block, if it's sloped with no step, it's the rf2/rr block

I broke my plastic suspension holder right away. Got the "narrow" aluminum ones. Expensive but worth it. I liked how the buggy handled as well.

Just ordered my buggy. I went ahead and bought the aluminum holders. Those will be installed from the beginning. Looking forward to building it. Hopefully I can get a bit of practice with it before the Bigfoot race on the 1st here at Mike's.

Is this battery punchy enough for stock racing? I see its rated at 40c continuos and 90c burst. Most other shorty batts are at 65c to 90 or 100c. But I know that it's not always accurate , as I've had 50c's out perform 65c battery's before.
But the crc is a great price for them.

I have the $450 question for today...

Where can I find one of these bad boys in stock? The IRS finally gave me my money back and I am ready to shop.

Wise choice!

There is one on eBay from absolute hobbies for $479, with a "make offer" option. I would offer normal retail price and see what they do... They'd probably take it?
