Default Pro-4 set-ups

Guys;

It will be a couple of weeks before I get to take the Car out again (this weekend it was Nitro racing).

In the meantime I have the pivot block spacer set coming.

It would be helpful to know how much anti-dive to add and if changing the inboard front toe (hinge pin angle) would be worthwhile in loose conditions.

Thanks,
Steven

I have had good luck running .5mm antidive with the oneway on a large high bite track. I would start there and maybe go to 1mm.

From past experience, taking out front inboard toe will calm the steering down and not be so aggressive entering a corner but it can slow corner speed down as well.

JDXray they look short because you run 2 spirngs on one shock..


As for aluminum knuckles, I would not buy RC square's knuckles.

It is the designed very well... There is a major weak point in the design...

I am gonna try to get ahold of jet racing's 7075 knuckles

I see the jet breaking as well..... on the stock knuckles the area where the screw goes into is well reinforced... and I believe that the Square knuckles is also made of 7075 aluminu... it is just recently that Jet switch to 7075 alloy...before they used a weaker aluminum and parts always bent or broke easily....

Wow, didn't notice that area is pretty thin. Jet part is only half price of Square. Give us some feedback when you get Jet knuckles, Steve.

I agree with you 100% these knuckles are very weak....I have bought the Jet ones and they are much more "BEEFY" around where the screw mount holes upper and lower....I have yet to have a problem with bending or breaking the the Jet ones

I have snapped both a front steerng knuckle and a rear hub in two pieces last two practice nights. I dont think that means theres anything wrong with them-in fact that means they are ultra stiff-which is good. They snap-dont bend. I might consider the aluminum ones-depending on the weight penalty.

Default one way gear?

Im looking to get another car and I love my Evo III but am getting tired of the one way problem. So does the pro 4 strip one way gears or did HPI get it right with the pro4?
