what would be the benefits for the lower shock tower?
more steering or something?

Lower to match the Hara Pro4 shocks better. That shock is 2mm shorter than stock shocks. Lets the front of the body sit down lower also so you can run the body more slammed.

haven't seen the square shock towers..but I'll keep a lookout for it..
as far as I know..when the pro4 was originally released the shock towers were higher..than later changed after a few months to sit 2-3mm lower... I have both HPI versions.

Thanks RCZ I did find some at RcMushroom just now.

Interesting that info on the HPI towers. They are much cheaper so I'll have to see if I can compare the old and new somehow.

hey I just drove my Pro 4 last night since a year ... Just wanted to see what it would do against " today's " competition .... in a field of good Xray drivers ( A main 9 xray's 4t2's rest 05's .... me Pro 4 I qual 3rd )

In the main I poped a ball cup, but my times were as good as leader .

I run on carpet with foams ... damn this setup works!!!

I'll have to post pics but.. I did the rear shock "flip"on the rear.... meaning my rear shocks are on the inside of the rear cvd's I had to flip the rear arms too. ..... but MY GOD !! the car rotates soo much better

I'll fine tune the setup on "high grip"carpet next week and then post a setup .

but you carpet foam guy's will luv it !! I am running the extreme 3mm chassis though too

that is very interesting what you did with the rear shock tower and shock assembly.

but how did you get the shock tower flush with the rear diff housing / bulkhead assembly sitting up straight?

and when you say the car rotates so much better do you mean you now have a smaller cornering radius or just more corner speed.

would love to try to this out let us in on the details and some pics if you can

cheers

Default Broken rear bearings

I've had my Hara Pro4 for about 4 months. I think it is a great car, but I have been breaking things on it more frequently than on my previous cars (TC4 and JRXs).

Now that my driving is improving, things are better. However, I was surprised today when I was doing some maintenance and saw that the bearings for one of the rear axles had broken (the center portion was at a nasty angle to the rest of the bearing). After just a little prodding with my finger, the bearing completely came apart and the little tiny balls started to spill out.

I have side swiped the boards on several occasions with the Pro4 and with my previous cars, but this is the first time I have seen the bearings break.

Has anyone had similar experiences? I'd love to hear that this was just a freak occurrance and will not happen regularly.

Ira

I'll post some detiled pics and how to 's after next week's trophy event .. I want some conrete evidece first with Top notch competiton. To see what the car does.


I"ll post some pics tommorow and see If I can get some moe input. I think with sway bars ( black all around ) The car would be dialed ... Unfotuallly rear sway bar would be a problem with the mounting ball on the rear with the arms flipped..
( I may have to dremel (( insert jrxs sound )) the front of the arm to fit a ball stud)

I'll run a quick set up by all of you to see what we can do to increase "mid" corner speed. Entery is fine , so is exit, seems to unload speed in the middle of the turn slightly,.... think If I can correct this ... it's by by local T2's ....

Heres's a quick run down

FRONT

Pinnk HPI springs (25mm)
top hole -- 3rd hole in ( extreme chassis tower)
Bottom -- 2nd hole OUT
60 Fluid in shocks
6deg carriers
Pins flat (thick silver shim) under blocks
0 Block front ( HPI Graphite option rear hole _ 1 shim )
PARMA Cyan ------Paragon 3/4

REAR

Flour Green springs (25mm)
Top hole 3rd in (extreme chassis tower)
bottom -- mid hole ### ( arm flipped)
40 Fluid
Ball stud -- outside on carrier
Pins flat (thick silver shim) under blocks
2.0 rear block
Camber 1.5 neg
Camber link ( HPI Graphite option outer rear hole _ no shim )
Parma Megenta rear tires


I'm probably forgetting a bunch of crap ....but you carpet guys get the general idea. Any suggestions for the "mid corner" is appriciated
