50wt oil...if our running outdoors on asphalt you may want to drop it down to 40F / 30R depending on your track...

What would I look for if the shocks do not fully exend at the same time? My shocks seem to be full of oil with no bubbles.

Also, do any other manufacurers spring work on the Pro4? For example, Associated makes a set that has 6-7 different spring rates. Will these springs work on the Pro4?

the one that extends last..you may want to add a little more oil and retest.... don't need to be exact on all four shocks.... to me close enough is fine....

I think the AE shocks will work...I don't have any so I can't confirm... I know other racers here have tried it...

Associated Springs do fit, although mine a little tight on the shock cups.

Default Building the HPI Pro-4

Guys;

Well I FINALLY found some time to work some more on this Car.

I am really impressed with the Hinge Pin mounting system. What an improvement over anything else I've ever built Electric or Nitro. No slop what-so-ever, and it looks like it will stay that way for many months of racing.

Thanks for the tip on buying a 2mm Driver. This has made installing the screws so far a breeze.

One question:

The kit supplied Shock Springs are very soft. I have the all of the HPI 27mm Springs. Any recommendations on a Spring starting point for outdoor Asphalt?

Thanks,
Steven

the stock gold/silver springs seems to work alright for stock racing...

the stock springs are 25mm high.. 27mm might fit...

RandyB,

Right now BSR is buying there rim directly from Jaco. They get their foam from the same source, but glue them up themselves. Basically a Jaco right now until Foister gets the rim done. They are nice tires.

Default Diff-Inner plastic ring

I know instructions say to glue inner plastic ring on rear diff, but why? I have run mine at 4 races and have not felt any thing bad developing from not gluing. Gluing it in seems to be asking for trouble with bad alignment. Any info would be appreciated.
