Well,


I finally gassed up my Cup Racer for the first time today since I got it almost a month ago............too bad it was in the house!! I had ACL replacement last Wednesday and finally "found" time to solder everything up. I dropped in a Sidewinder 5700 on 2S with a 37/60 gear and the car still has alot of pep!! Hope to let it run loose by the end of the week!!

Andy - what's the 'trick' to using the 'b' plates on the steering knuckles??

I just put mine in and I had to almost unscrew the ball cups on the knuckles that there's practically no screwed in

is there a 'new' turnbuckle that should have been packed in the plates? Because I'm not confident the first time i nudge something the steering rod dont come apart

I also noticed that the aluminum threaded shocks don't come with directions - and there is a part you need from the shock parts tress, but it isn't identified any place..I'm glad I've built shocks like that befor and know that the little retainer spring isn't suppose to sit on the o-ring but on a little black shock bottom

Hi,

Are you referring to the #87070 aluminum shock bodies or the #87597?

Unfortunately the 87070 shock bodies do not come with instructions but the 87597 should have instructions in them.

In regards to the "B" plates I was informed that you would need to construct a custom knuckle for that option. The "B" plate was the original plate from the initial design of the Cup Racer. The testers then felt that it was a tad too "quick" so we opted for a more stable plate design. having already designed the original plate we didn't simply want to ditch the plate. So it's offered as an option for those who would like to try it.

Thanks,

AH

thanks Andy - yes, it was just the shock bodies didn't see the need for the full setup

well, that just plain stinks about the 'b' plates and having to make things up...guess i'm going back to the 'a' plates for this weekend and then try to figure something out

You can use the "regular" mini wheels/tires with the Cup Racer (...just need to adjust the gearing accordingly)

We ordered the yellow hard 26mm inserts from HPI and were gonna cut them down to the same diameter as the foams that come with the "m" tires. Glue the ends together with shoe goo. Were hoping this will make them last longer and handle better.

So..when is your manual coming out again? We'll order some

Also In re: B Plates, I meant you need to make a custom length "turnbuckle" not custom "knuckle".

I'll let you guys know. Were running the johnson motor with the tazer 15t esc. It's are version of a spec class and it seems to be taking off pretty well. It's all based on driving ability and not who has the biggest wallet. Were trying to find a way to get the tires to last more than 6 races(2 weekends) til HPI comes out with a harder compound. I know they can cause they have the material to do it.

Can anyone recommend a reasonably priced (<$80) brushed ESC to run a silver can or other "scale" motor (20+ turns)?

My only requirement is that it have an intergrated li-po cutoff. If I can't find one in this price range, I'll just go brushless.

Thanks,

Lamar

I think you should just go with an independent lipo cut off. Novak makes them. I dont think you are going to find a brushed ESC with a built in cut off. If you are half cocked to go brushless then I would suggest that you go ahead. I dont think you will be sorry.
