Andy,
AZBobby brings up a good point about the foams. While I'm always happy to see another company get involved in tires, these days I'm actually getting more interested in what kind of foams come with the tires. It'd be my preference to just stuff the foam that comes with the tire (imagine that concept for the racer that PAYS for all of his/her equipment) instead of buying another foam so that you can actually get use out of the entire life of the tire. BTW, the tires do look great and it is good to hear that the tires will last over a longer period of time than the competitors.
Anyway, do you get what I'm saying about the foams though? It'd be one thing if I got all of my tires for free, but since I don't, I'd prefer if the foam lasted longer than 20 minutes of runtime. We all know Proline has had serious issues in this dept. for years, Panther can't seem to decide if they want to stuff a soft or ultra-megahard-stiff foam with their tires, and then you have Losi which isn't too bad.... but not great. This is mostly seen I think in the 1/10 market where most people will be putting the Trinity grey bomb-one foams in their tires, but Trinity has just disappeared as of late and their foams are nowhere to be found.
Sorry about the long rant here, it'd just be awesome if JConcepts truly broke the mold and offered a great working tire that lasts long (already accomplished) and packs in a great working foam that is usable in just about every situation (similar characteristics to Trinity's Bomb one) that lasts the entire lifespan of the tire.

Regarding that tire and the indoor track. If the track is dried out and un-watered that tire may work very well.
The tire looks like it would be a perfect match for the varying conditions of the outdoor track.
Kevin, are you coming to the Nitro R/C Pro Series race? How about the Race Against Cancer? Doug McCullough has alot of big races on the horizon....Doug runs a top notch facility.....

First i have to say sorry to Brad. not sure what was on my mind when i kept refering to him as Brian. Sorry again Brad.
Flybywire you got it, anytime. sometimes it is good, usually so close to Cactus guys are still amped up from running them that it is good. i will be carrying it along for a few weeks for sure.

I have a question
my BJ4 (not the worlds) is second hand and I have alot of slop in the front were you thread the button head screw up through the bushing and into the bellcrank .If I tighten it right up then the steering is to tight and if I back it off even a mm not even ,it loosens up but the slope comes back ,(Go Figure) .
Can I use a AE shock gromet some how or what do you suggest.Also I haven't tried the loc tight but that would freeze everything up I think .A flat headed screw was in there tight but lot's of slope in there????
This is so weird I tell ya .Hope you can understand my confusion .
please LMK
Thanks in advance to all that can help

[Laterilus] -I completely understand what you mean about being a customer, as I am one. As far as addressing the issue of the foams, dont worry, we spent quite a bit of time on it. Im sure you'll be more than pleased with the results by the time Jason gets done tweeking things.
[Muppett] -If you really have an issue, please pm me.
[blackdog] -PM sent.
FYI guys, pics of some of the new items were recently taken so keep an eye on the website next week.

Muppet, just an FYI, as it seems you may not be completely informed.
Jason designed Pro-Line tires for quite a while, and bodies, while working for them in California...before moving back to Florida and starting his own company.
I'm not sure about the D4 reference, but I guess we can accept alot on that subject if the designer/engineer worked for both companies?
Besides all this, they are different anyhow, so it's a moot point. It's all in the details.

you just have to email them to buy the sway bar, just click the "Email for Details" link right beside the price, and it will take you to a page to send them a message, and they will email you an invoice for it, if you want to order other stuff at the same time, include the part numbers in the email to them about the sway bar, and they will add all those to the invoice as well,

Need to revise the "Heavy Duty" front arms again....They are not that heavy duty. Either that or sell me stock in the a A arm division of JC...ha
seriously though, it is still a weak point of the car IMO.

^^ Yeah that's funny. I was looking at them at a race on the weekend and was going to try that. Some dude on here is selling Delrin arms as well. Got a set of those coming. I am not really that hard on the car and am an A Main driver...I just have brutal luck with the HD arms....I've gone through half a dozen or so since I've owned the car. Enough that I may switch cars all together.

[Kevin Boyle] -recieved and replied.
[johnnyboy] -I wish revising a piece were as easy as posting about it needing revision, haha. To be honest the front arms are a weak point, as on every other offroad 1/10th car. Are you running a front one way?
[oople] -I wonder why they're almost a direct fit
