by the way, talking about weight, can anyone tell me how much your pro4 weights?
i have pro4 with novak ss5800 brushless, futaba 9451 digital servo, hpi rubber advan tires with dish wheels and profotorm
stratus body, total weight 1520 , isn't that too much?
That sounds about right with a brushless system.

Mine is way under weight with normal esc and motor (1460ish).
This isn't a bad thing for you can put the weight were it needs it on the chassis with lead weights.

I haven't boiled mine...
I think boiling them would add more flex...
Eric would be better to answere that...
to boil or not to boil....

A very strong LIKE from me. I have used the titanium racing spool and I loved it. Getting the HPI one in a few days and will be putting it straight in for where I race.

One of the drivers locally ran Delrin outdrives running stock, 19T, and Mod and never complained about them.
I'm using them in 19t and i'd say the wear rate is high, even compared to the std. parts

Default High Traction Arms

From my understanding the only reason the new arms have come out is that they were breaking at the worlds. The extreme bite that the track gave and the INSANE motors being used meant that corner speed was ridiculous and since the compressive force in the lower wishbone is about 3x higher than that in the turnbuckle, it was causing them to literally break! i heard that some of the FAST teams drivers would go on practice runs and without any collisions arms were breaking. Guess these less rigid new arms will help, maybe it was just a bad batch though that were a little too brittle, i think that the team just replaced all wishbones and the problem went away, maybe they got a bit worried and thought the problem should be sorted.

Just my thoughts,

Rob

I can't imagine they were just snapping arms because of the power in their cars...

It has more to do with having a softer arm to run on asphault.....which since are softer have a little more flex which would possibly give you better traction. Same reason they use a 2mm chassis instead of a thicker.

Once we can get them here in the U.S. I'll probably buy some...pricewise it's a pretty good deal because you get all four arms for only about $3-4 more dollars.

I would think that foam tire mod has much more stress loads to the arm than rubber tire racing on any surface. Plus this is the first time I had hear of arms breaking at the worlds during no contact situations.
