Reggie: What's up man? RU coming to the Birds? I can't race this year because of school but ill be around.

Ooj: To my understanding the "high traction set" uses a softer more flexible material for the arms, they may be good for running on asphalt where you may need the extra little bit of traction. I would like to try a set myself along whith the 2mm chassis. We normally race at night and you tend to loose some traction as the night gets colder and the dew settles on the surface.

From what I can see they are the same - the high traction arm set is just a bundled package pair of the standard set. Can anyone confirm or disprove this?
I belive the High Traction set has more flex that the standard.

Guo- everybody uses the TC3/4 diff screw and nut. If fits perfect. I still have snapped 2 of them and a few people at my track have too. We also run the diff upfront pretty tight, but not locked. THe mod's seem to still sheer the heads of the TC3/4 bolt off. Maybe someone has found a beefier screw that works better.

Default Who's going to Snowbirds

I'm headed to Snowbirds this year and just wanted to know how many other Pro4 drivers are going to be there?

Eric: who's going to be representing HPI at the Birds? Didn't see any HPI names on the entry list yet.

I am able to fit a standard size servo into the car now with the set-up I have.

Default I'm already registered in two classes

Pucho you should check the entrant list, I'm in stock and sportsman nineteen turn. Hopefully this year will be better than last and I can run the entire event with the HPI instead of having to use an X-ray.
