I am not sure exactly what percentage balance that yields but I would guess its give me no more than a 5% difference between ends. I have tried 10g blocks in place of the 5g I use but when doing so the car seemed to want to swap ends and/or felt like the off-power steering was delayed.

In my experience I would say the Losi is more sensitive to weight distribution than most cars making it an easy & effective tuning option.

If you like I can post some photos of how I balanced my chassis along with the weights I use to shift that balance.

Has anybody compared the new Jaco's (green and blue) to Sorex 28's in back to back runs (carpet)? My car is pretty decent on the Sorex tires, but looks like a drifter on the Jaco's.

Did you add extra camber with the Jacos?

Just under 2 in the back and about 1.25 in the front. Does it seem to be normal to only wear the inside of the f tires? After 5 or 6 runs the outside of the fronts are still glossy. Maybe the Jaco's get better after a bunch of runs and the Paragon starts to soften them up and eat at the insert. I did notice they have much less air gap than what I am used to.

The only reason I am contemplating trying to make them work for me is I just have a hunch they will be the handout at the Snowbirds. Otherwise I would just stick with Sorex.

Last weekend i bolted up some blues (used, mind you...) that where left over from the asphalt season and headed indoors for some 10.5 rubber. All i did was clean the crap outta them (scrubed them down with motor spray) and added jack the gripper.

The tires look new after every run (no buildup) and i had way more traction than i expected all day. Dunno about the 28's though.

So, does anybody have a rubber tire carpet with a spool, with a13.5 or faster motor, setup that they want to share? I am going to make a 2 hour drive on the 1st and would like a setup to work on. Thanks

Tires that you run don't matter to me. But I have to run the Speedmind 28, they are a Spec tire for out series.

Default Spool assembly - ESC placement

I've recently built a new Type-R, and am going to be racing Jaco Blue rubber tires on carpet (local events only). I wanted to try the spool instead of the diff, so I purchased a spool pulley with the plastic plates. I was wondering about the best way to assemble the spool. Do you leave the copper washer in place? Also, does anyone use grease behind the copper washer or on the spool plates? Any other building tips?

Additionally, I wanted to place the receiver and the Brushless ESC (LRP Sphere) on top of the battery plate to keep all the weight centered. Does anyone have positive experiences or issues with placing this weight up high, even though it's centered?

Thanks for the thoughts.

I mounted the ESC up there once and it felt weird, this car rolls alot to begin with, your better suited keeping the weight low. If you are running lipo you will need to add weight anyway, so you can put a good amount on the opposite side of the chassis to keep the L/R balance.

When you build up a spool keep the rings dry and clean, just use some motor spray and then your set.
