How much faster are the laps with the 13.5 over the 17.5 car? Thanks

it depends upon tires...
i think at last year's nats the difference was nearly 1s at our track.

Posted my fastest setup from yesterday.
http://racerlog.com/wiki/T.O.P._Photon_EX#Setups

Yesterday I think I really learned the impact that rear width makes, above and beyond rear toe. When I went from RF 1.0/RR 3.0 to RF 0.5/RR 2.0 the car really woke up, more than any wheelbase change. Additionally when I went to RF 0.0/RR 2.0 the car was as loose, or even looser although I had more rear toe. I think I'm going to run RF 0.5/RR 2.5 to start next week along w/ a longer rear wheelbase.

A friend of mine has issues with the shock's spring adgusting nut. It has big play and after a run it changes position!! He tried to force it with hand with same effect. That is the case with 2 of his shocks!

Any ideas what might be the problem?

Have to ask, does he have the oring installed correctly into the collar? (I assume this is what you mean by the shock spring adjusting nut).

nnick

Yes, this is what I'm talking about. Are many ways to install them?!

hanulec

Nick - did he install the oring in the collar?

On the scale of wrenching fails, I've seen a lot worse from you! I do show up to races with a setup board and tools

+1 I did that the first time I built xray shocks when I was a noob.

Luppi Stefano

me too, I change spring adgusting...
the problem, for mè, is bad anodizing...

you can try with thread lock...small amount...
--------
Saturday First Run with EX, isn't good day...the car is faster, but very difficult to drive, rear slips in medium corner...totally wrong ackerman, std setup isn't usable, next time new setup completely revised!
I have good feeling with Gear Diff no problem, only small leak from lateral o-ring

Luppi - what setup did you apply? Kit instructions? The EJ setup within the instructions?

can u elaborate on what you are planning to try next? Are you running the aluminum v2 steering blocks?

Luppi Stefano

similar kit setup, only difference is 400 cps oil with 306 spring front and rear, gear diff 1000 cps
unfortunately I haven't V2 steering blocks, in italy we haven't yet!
planning to try a setup more similar to "old" Photon: 3mm ackerman, long links front and rear, front arms with 1FF 0FR, 1mm rollcentre RF RR, gear diff 2000 cps
