Thx mark

Can't thank you enough for staying late and letting me get my first run in

Good News: Dave has my car pretty dialed

Bad News: I cant blame the car for the crashing and crappy lap times

I should be there Sunday to help peel the paint off the rails

The stainless screws from RCScrewz are the first thing I bought for my 10. Best investment ever. Those ali srews are light, but only last a few rebuilds before they're trashed. I don't have the patience to be careful with screws!

I'm glad to be back. The LE seems to be an improvement over the original as far as assembly and simplicity is concerned. It will probably be an improvement on the track as well.

Like Pan Car Racing? - live in Ontario? - Check Out LOU's Speedway near London - lots of Pan Car Racing here.
John,

Thanks for the kind words. It's a pleasure and an honor to have you back in a CRC ride. When I heard you switched brands, I was really bumming thinking we let you down. If you (or any other racers with CRC products) need any assitance with your new LE, pop us an e-mail or call.

We want to get up to Lou's and race with you guys, please keep us posted if you have any trophy or big races this season.

Peace,
Frank

Talking

Frank

I'll post some of the SCAR / WGT Challenge Dates soon. I picked up a GenXL 12th Scale as well to go along with my BattleAxe. Back to all CRC Cars.

10th Scale Pan Racing is the biggest class at Lou's Speedway Wednesday Night Races. We're running Circuit and Oval Races on the same night. SCAR Circuit is the biggest Road Course Class and SCAR Oval is the biggest Oval Class on weeknights. 12th Scale is also making a comeback.

SCAR (25.5 Novak Motor / Havoc 2S Sport ESC / Orion 2400 Battery / Spec WGT Tires / HPI 4 Passenger Body) will be running at the Canadian Nationals along with World GT 17.5 Single Cell Open ESC in January in Welland.

I really like the hardware with the new GENX10 LE as well as your shock.

Talk to you soon.

John

What are the trade-offs running laydown servo compared to angled servo?

Here's what i did to mine and it seems to make the car better to drive...
Parts used are Tamiya servomounts, F103 turnbuckles, TRF F103 sentershock and Tamiya servosaver.

With the tie-rods completely flat, you will not have ackerman angle. So the inner wheel and outer turn the same amount. Not a big deal on a pan car, but a huge issue on a TC.

Whoa there Shawn. With tie-rods flat, the issue is usually added toe-out upon slowing or braking; but, not Ackerman.

Ackerman geometry is derived from the tie rods being connected inward from the pivot point of the steering knuckles. CRC offers three options on the steering knuckle arms for Ackerman effect; and, TorroRosso has his tie rods connected at the inner hole making for plenty of Ackerman.

However, I do agree with you that tie-rods being setup flat is not necessarily desirable.

I found out that inner wheel turns more than outer wheel with this than with original set up. Our track is quite twitchy. Atleast now i beat the F1's with it.
Had lots of trouble setting the car up before, now i'm very happy.

You're happy...We're happy (to help)!

I often setup the tie rods to go slightly downward from the servo saver attachment point towards the steering knuckle arms. I usually like my on-power and off-power toe to be the same (i.e. zero) for a fast flowing track. Do like flat tie rods to create toe-out on a really tight track.

Depends on the track. High-bite I start Fronts and Rears at 2.10" For Medium or low traction, around 2.14" at both ends.

I have been trying to figure this out for a while.
Is there any thread/web page that anyone is aware of that
has a detailed description of servo placement vs tie rod angle/placement
and how it effects ackerman and/or tow (and what it will do to the car)?


Thanks

You have a CRC car. Ask them directly. Excellent customer service from deem CRC boys.

You should take a look at the Hudy setup book. Im shure, there is something about Ackermann in it.
If that's not enough, read Allan Staniforth's "Competition car suspension". There are a few pages about Ackerman.
