Ok, the CR has been available for a while now..Does anybody here actually race their CR on an asphalt track???
I only ask as Ive had mine for around 4 months and I am still disappointed with it. I have rebuilt it 4 times, changed front/rear diff settings, motors and springs etc and it still behaves on the track poorly.
Its noisy, glitchy and has no chance against similar models on a high bite track.
Any other racers care to comment?

mine works pretty good the last time I ran it - the noisey-ness is because of the meta gears, shaft drive and the 48P gears...
and I know a group that pretty much ONLY runs the CR and they all handle like they are on rails...

Maybe I'm too used to my HB Cyclone and its smoothness. I just feel that the CR is twitchy even with a Sport Tuned motor and was hoping I built it wrong. Ive rebuilt it and its still not much better.
Im using the rear metal shaft cup holder on the front and the stiffest gear diff spring in the front too.
I will have another rebuild this week and take it to the track on Saturday, if its still the same, I will sell it and buy a F104

i can't remember what kind of oil i got in mine, but I got the hardest springs in the front and the 2nd hardest (medium, i guess) in the rear - these are from the optional kits...I'll have to pull mine out and see what I got in it...

You haven't listed your set up. Spell it all out and I think someone can get you going. I ran my car last weekend and it is seriously fast and nimble and I'm really looking forward to the ABC mini series that will soon kick off next month
Here is a race with my cup racer from last year if you haven't already seen;

Also some good news regarding the plastic front input cup. We've developed an alloy hard anodized cup that will be here late August!

My basic set up is:
Pink springs on front
Blue springs on rear
Hard spring in front diff
23t Tamiya Super Stock
Tyres: HPI standard CR on Porsche rims or Sweep 33/40
30w shock oil
Short wheelbase option as using Porsche body
I will keep trying different set ups and see whats best.
Thanks for the help guys.

Hi guys!
I have a problem with my CR. When I am going to tighten the wheels, the plastic cups is being twisted by the pin that is going through the shaft and cup. What do I do wrong?

My droop is set with arms at level (make sure it is equal left to right).
Rear toe should be at 3* with the motor you are running.
Front caster all the way back.
I use 36 degree Atomic tires with medium insert. These tires are awesome and handle like if they were Sorex
You may need to find a bigger wing also.

Well,
I just got back from the track and am pleased with the CR finally.
I changed the front gear diff spring back to the softest, changed the wheelbase back to 225mm and used my Sweep 33/40 tyres.
It seems much quieter after the rebuild and smoother.
Only raced against my friends M chassis, both with 23t brushed, and the CR was much quicker through the corners.
