Default half shaft half belt drive

thanks

maybe from their usage of words ...."exciting new front DRIVE shaft system" i never heard those terms to describe a new type CVD/dogone design. i was hoping it was a front diff assembly that is a diff and oneway combined


anyway i'm glad then it's all belt

Will the existing springs for the xxxs fit the new shocks on the jrxs? I guessing they will but you never know.

It would look like the springs would be the same, but the shocks are different. But i don't know for sure. will have to look into it more

the drive shaft thing.....LOL...I have been in the hobby too long, someone says drive shaft i think Dog bone, CVD, Halfshaft, Tamiya days...lol O well.

And just how is a tranversely mounted engine in a typical FWD car going to apply a twisting torque around the long axis of the car?????? If all cars had longitudinally mounted engines, you'd be right. Silly rabbit.....

The new shock will use all new shock springs. The new springs are shorter than the old ones.

It's all in the terminology isn't it.... I would have called them motors not engines. Engines (to me) are the ones in nitro cars. No offence meant either, just interesting really.

Default JRX-S Christmas

The big boys of Team Losi (Matt Francis, Todd Hodge and Gil Jr.) were testing on Stockton carpet track from this Monday through Wednesday with their new JRX-S cars. Their goal was to develop some good setups. The most important setup being for an upcoming race in Copenhagen, Denmark next month.

Matt said they have developed a good 19-turn setup using rubber tires for us mortals.

Todd demonstrated the smoothness of the new Losi front drive shafts (LVD). S-m-o-o-t-h to say the least.

Gil showed me the assembly process of his LVds. The internal workings of these LVDs include two pivot points instead of only one as used for a typical CVD. The pivot pins are held in place by the shrink wrap tubing that covers the two pivot points...Simple with no screws to add weight to the assembly and shrink wrap to keep dirt out...Absolute genius!!!

After three days of development progress, all headed home to get some well deserved rest. That's a long way away for Todd and Gil (being SoCal guys).

I couldn't get any of them to play Santa and accidentally leave a car behind. But, I am still impressed anyway.

Merry Xmas.

Default Torque Steer

Torque steer comes from a car that has the same tires that are steering it involved in powering it (either a FWD or AWD), this has nothing to do with which direction the engine is mounted. A FWD car will have torque steer whether the engine was mounted longitudinal or latitudinal, doesnt matter.

Same with RC's, the direction in which the motor is mounted has no effect on whether you will feel torque steer or not.

Looks cool, what are the advantages of having the double joint?

You don't say! j/p

While there are not many longitudinally mounted engines in AWD cars, they can indeed suffer from increased torque steer based on engine torque. Here's a few examples; Skyline, every AWD Subaru, older Ford Cosworth Escorts, GMC Sy/Ty, etc

Ever wonder why some drag cars pick one front wheel up in the air? There is enough torque present to pick a wheel up because that action is easier than moving the car forward. Usually this happens because the chassis is not stiff enough to support that power level, but can also occur from extremely soft rear suspension settings (among other things). This phenomenon can greatly increase the feeling of torque steer in AWD vehicles with longitudinally mounted engines by unloading a front wheel. This can also happen in AWD vehicles with transversely mounted engines but not to the same extent!

Wanna really melt your brain? Is that phenomenon caused by the direction of the engine rotation or the rear driveshaft rotation, only with respect to AWD & RWD w/ longitudnal mounted engine?

Sorry for hijacking the thread. If it's any consolation, I'm buying a JRX-S!!! ....just hoping I'm not assembling it on Wednesday Feb.9th (know what I mean?)

Default Are they...

going to make them for other cars?

I sure wish they would make kevlar spurs for others TCs. If someone is not going to buy their TC, why not take advantage of part sales. I mean, who buys a TC just because they have kevlar spurs? No one, but why not sell some parts to them? I really liked the kevlar gears on my XXX-S. I miss her. I want an updated XXX-S for parking lots.
