I agree with that. But for a club level racer (like me) a good reliable car with parts support from my LHS is the best investment.

I think that this car will be a good car based on the cars performance at two major events. As for the arms being too short,
maybe losi didn't do a short arm car just so they can have the battery placed in the middle. the battery placement could just be
added bonus in the short arm design instead of the arm length or
geometry being comprimised just to stick the battery in the middle.

I personally disagree. Often times the first thing the racers say in interviews is 'this guy' or 'that guy' was just "on" that weekend. Or they just had the "perfect setup". The feel I get when I read those interviews is that when a guy goes out and dominates, people figure he would have done it no matter what competition level car he was running.

I think the biggest indication of whats actually doing the yo-mans work in winning, is when guys switch teams from one car to another and just keep on winning. Barry baker didn't lose anything when he made his switch from Yokomo to Associated, years and years ago Brian Kinwald didn't lose a step when he switched in off-road. Yukka Stenarii's(Sp?) switch from Schumacher to Losi, the list goes on and on...

If these guys really believed it was the car, I doubt we would see team jumping as often as we do these days.

Another example...Take a look at a guy like Hara who continues to win with HPI's nitro car. A car that so many "experts" on these boards suggest is nothing compared to those offered by other brands. If its the car, how can he consistently win with an inferior machine?

Yep...yep...yep....sign me up for the camp that believes all competition level cars are pretty much equal when all things are cnosidered. Its the drivers that are doing the winning in my book.

my 2 cents....

...well it was kinda a long post, so I'll say 2 1/2 cents...

If everything else were equal, the car would make a significant difference. But in real life, things happen. (ex: 2002 on-road gas worlds, Serpent 705 was on a clear path to victory, then his gas tank broke, so Pavidis kept it cool and took it hope, on top of that Pavidis radio centreing spring broke during the main, but still kept it cool. Another example: At this years US champs, Paul Lemeux's car looked faster, he scrubbed the board early and Josh made a clean pass, Josh kept a perfect line till the end, does that make the X-ray better or the JRX-S...you decide). Take all these car reviews with a grain of salt, choose what you think would make you win.

Default short arms.

I will preface my comments with the fact that I am not an engineer for 1:10 cars.

Now for what I know, there 2000 lb bigger brothers.

Before anyone pans or promotes the short / long arm you need to know which is relative. Is short, short because its just not long? I know I am playing with words, but stick with me here.

Roll up under your car. If you can, take a look under a vette, mustang, viper, or some other higher performance vehicle. You will find striking similarities to the width of the suspension compared to the JRXS. Since I do not have access to the measurements of the JRXS, I can't be specific.

Yes, an arm too short would require different suspension tuning techniques than a "long" arm.

With the 2000lb cars, you don't want long arms like they have on the offroad cars. The longer the arm, the more mass you need to move for the equivelant movement of a smaller arm.

If you've ever raced a 3000# car on a road coarse, you will know that on a track where you need a responsive car, one that has fast longitudinal movement, you move your arm pivot points closer to the wheels.

You can't simply just use a shorter arm. Everything has to change, camber links, shock locations, steering setup. Everything.

To sum things up a bit: it's about the longitudinal movement. Short arms on a car with the battery / motor mounted off the centerline would require some serious magic to work. Remember the shelf weapon? I had one too.

If you have nearly all the weight centerline, short arms will allow you to adjust your car without changing everything. I would take a guess that the Losi drivers use camber link / length and ride height (tire diameter) to do most of the adjustments. Once a driver finds the spring / shock oil/ piston he likes, I don't think he would change them. Maybe only a "tight" setup and a "loose" setup.

The most important thing is the overall design. You cannot simply use arm length. Its nearly like comparing apples to oranges. You need to talk about the tree they grow on, too. I am guessing Losi engineered this car like we engineer real street cars. With specific tuning options in mind. When you get to a track you don't have time to mess with everything. You know what you like, get a nuetral setup and go from there.

Since I am not a team driver, nor do I drive like one (hence I be mechanic), team drivers comment please.

Thumbs up

That Mod TC race between Josh and Paul was AWESOME. Mad props to both drivers. For Josh, who didn't blink an eye under tremendous pressure and ran a flawless race. And to Paul who threw down everything he and his car had, but was professional enough to not even come close to hacking Josh to pass him, while sticking the nose of his car just about UNDER the back of Josh's looking for an opening to pass. Truly, racing at its very best. If that race was captured on camera, it will be the racing vid of the YEAR.

I'd love to see it too =)

Alright, who let this rational, concise, intelligent person post on this thread?

Such a departure from " i dont no bout you, but i think this cars crappy".

The thing that was the coolest about that race was when Paul almost passed Cyrul on the outside coming into the first chiccane. Paul's car just carried so much more corner speed than Josh's.

That track looked super tight and really hard to find passing lanes. So the littlest mistake can cost you everything. Sounds like a great race.

First off im sorry that im too lazy to sift throught 48 pages....


I know that the battery is installed through the bottom of the car. But what actually holds the pack in place? IS it a squeez fit between the upper deck and the lower battery tray? Or is the pack tapped to the lower tray? Basically what stops the pack from moving around?

Thanks
