I read the first 75 pages of this thread. I really like the car but, is it easy getting spare parts for this car? I would like to race in a mini class but if its hard getting parts for it I might have to go with a different car.

Towerhobbies has the parts but hard to search for. Some of the parts aren't list as "cup racer". Stormerhobbies has the most parts for this car and easy to find.

I haven't had issues getting parts other then tire selection. Once I found out in this thread that you can run Tamiya M-Chassis wheels and tires that became much easier. Most parts I have been able to get from my LHS within 3-4 days.

As for the competitiveness of this car I compete weekly in club races in the brushless open class. The cars I compete against are are regular 1/10th stuff a few TC6, Xrays and Sprints. Right now out of 32 drivers i'm sitting in 5th place. With the ease and adjustibility of the Cup Racer it's all come down to setup. The floor we run on is a hardened rubber and it seems the only tires that hook 100% are the Schumachers which they don't make for the Cup Racer. I think with the Schumachers I would be top 3 however I am quite content with where I stand currently.

Nope not a problem at all. This is my first time working with an on-road car so maybe my setup isn't the way it's supposed to be but it works and the car is predictable. The surface we run on is a hard rubberized gym floor and it's slick!

Are you referring to schumacher mini pins? A few years ago when there weren't much mini tire selection I used to cut down 1/10 sedan slicks.
1 Cut one clean cut straight across tread of the 1/10th tire with scissors.
2 Lay the tire around a mini rim
3 Mark tire bead where the tires begin to overlap
4 Cut off the overlap with a clean cut
5 Test fit newly shortened tire to see how the bead fits (hopefully not too loose or you may need to remove another mm).
6 Repeat for remaining three tire using the first tire as a gauge so that all tires are the same diameter.
7 Glue ends of tires together with thin CA
8 Install on rims

And there you go- Schumacher mini tires

Thanks!!! I have done that with crawler tires wasn't too sure how it would work with the on-road tires since the RPM's are higher. Might have to try that with a cheaper set of tires first since the Schumachers are expensive to get up here in Canada.

Thumbs up

Mornin All,

I've been away from the rc crowd since approx 96-98. My last car was an RS4PRO. Anyway, fwiw the Cup Racer has brought me back I have the Porsche kit and luv building it. Unfortunately, i have run into a few probs like stripping the thread on the rear differential screw ( part # 86392 ) and then using thread lock glue on the wrong part ( metal part # 86194 ) instead of the ( plastic part # 85281 ) when assembling the front gear case Anyway, apart from these two stuff ups i'm having fun and have learnt my lesson to be more attentive. Only draw back with getting back into the rc scene is i'm time deprived thanks to marriage and being a father. Fingers crossed my little lad picks up the rc bug when the Cup Racer is finished.

Cheers,
Brad

...i am in the same boat. My boys are 2.5 and 4.5 years. ....I am back into rc cars and crawlers because I need an outlet from the kids and wife. Love them all with all my heart, but also need some personal time now and then to do my own thing.

My 4.5 year old is getting into r/c'ing w/ me. I am actually working on a build for him, ...using a very slow 65t motor, w/ oversized monster truck tires. ...building something he can't break too easily.

Any other Lipos other than the Team Orion Carbon's with 4mm bullet connectors direct fit the Cup Racer? I have one, perfect fit, bullet connectors line up. Issue is finding them.

How true buddy. Personally, i'm absolutely in luv with this kit regardless of its minor flaws. Fwiw, its been a long time since i've been challenged hobby wise. Last time was when i built the original 2.5cc Serpent Impact back in the early 90's. It's good to hear your also getting back into the rc scene mate. Awesome to hear ya goin to share your knowledge and experience with your lads

Respectfully nods head your way,
Brad
