This forum has been a huge help to me
First off I just want to say thank you to all who have posted in this forum. I started at page 1 and learned a lot. I was very confidant in my purchase of a cup racer after reading all the great advice and positive experience of Cup Racer owners. I ran into a few rough spots during my build and was able to read about someone else with the same issue and a solution to the problem.
Thanks again guys.

after a few runs wiht an 12T EZRun brushless motor I did put the 17T Radon motor (that came with my SC10) into my CR . This one suits the car rather better.
Although I'd like it to have more breaking power... any ideas on that issue? Or got I just used too much to brushless breaks?
as for the front lights: I had to go with normal Pactra Silver paint for the inside of the front lights, as no chrome paint was available to me. Now as this finish isn't reflecting the light of the LEDs too well, I did some research and found some concave LEDs, that do spread the light differently and I like it much more. (I also tried 120° diffuse LEDs, but they weren't as good either.) As soon I can do a decent pic about that, I'll post it.

What size is that motor from your SC10?
Never mind :P I just found the specs for it.. It's a 540 Motor

Does anyone have a set up that works on indoor carpet. My car is set up with 225mm wheelbase and upright front shocks. Also running the gear diff in the front and ball diff in the rear. I cannot get the car to run well. The rear wants to drift. It is like the front is slower than the rear. Any help would be great. Thanks

My current setup using foams on carpet:
Front:
Front:
- HPI carbon shock tower
- Pink springs
- 70wt oil
- Outer shock hole in shock tower
- 1/2 degree toe out
- Stock droop
- 1 degree negative camber
- Stock rollcenter
- 5mm ride height
- Medium tight ball diff
- No swaybar
- HPI carbon shock tower
- Gold springs
- 45wt oil
- Middle shock hole in shock tower
- 3 degree toe in
- Stock droop
- 1.75 degree negative camber
- Low rollcenter (upper hole in shock tower for camber links)
- 5mm ride height
- Very loose gear diff
- No swaybar
- Lower rear ride height than front
- More front droop
- Raise front rollcenter/lower rear rollcenter
- Harder front springs/softer rear springs
- Thicker front shock oil than rear
- Front antidive (front of lower front hinge pins lower than rear) This is not good if the track is bumpy.

Hi All,
Finally finished my build, a few photos of the finished product for you.
Running the following:-
Found it an interesting build being my first HPI one. Kit had a couple of missing screws, a dodgy gear, instructions were out of date / wrong in a couple of areas, but in the end it came together quite nicely.
Haven't had a good blast with it as yet but will do so next weekend.
Enjoy

Lowering Plates
^ Nice ride fritzzz
Do these "Lowering Plates" do anything else than just "lower" ?? I understand that they are used to "lower" the under carriage when using bigger wheel/tire combinations but are they really needed even if you do use bigger wheels/tires?
I am asking this because some some people will most definitely be running their C Racers on tarmac and parking lots where their will definitely be bumps and stones around and some clearance will be needed for both actual clearance and travel.
