Do I need to up my camber from -1 to say -2 for these tyres?

My take...

Green: 24 (only by what I have seen from two other driver's experiences with them.)

Blue: 28 (wears slightly faster than the old RP30s; but, still a very, very good carpet tire. Loved them at the IIC.)

Yellow: Still needs to be developed. Certain that Jack can do it!

And I upped my camber to 1.75 with the Jaco Blues. Usually at 1.5.

How are these prism rims for durability? Our "sportsman" class has been fairly violent lately and I've had a spate of Speedmind rims going out of round on me.

The hex seems a little shallow to me, and the face of the wheel is a bit thicker. This makes the fit a little odd on my 415-mre as the rear uses .5mm spacers that cause the lock-nut to be a little too far out on the axle for my taste. Only a couple threads poke past the nylon insert. I've only run them once so far, so I cannot comment on how durable they are after impacts...

If you have full threads protruding past the locknut you're fine, but Tamiya also makes low-profile locknuts specifically for those who run spacers:

Hey Jack,

It was nice to finally put a face with a name.
The tires were perfect. I don't know of anyone who had a tire problem all week.
Thanks for putting in the effort and putting up with all the crap early on.......I think you've got a great thing going.

Hey fellas...

I normally run Sorex 36r's here in the 23T class in Japan. What Jaco rubber tire/wheel combo is comparable to them?

In addition, we also have another venue of 23T racing that takes place on a double tennis court that's been converted to a permanent track. They run foam tires at this event. Currently, everyone uses Active Hobby foams, since the company is right down the street. I know Jaco uses colors to identify their foam compounds, but I have no idea what would work well on a grippy tennis court. Any idea which Jaco foams would be best suited for that?

v/r,

- Paulie

We also make gas car foams that are rated by durometer. What shore readings are you currently using?

Hmm, not sure what shore reading. Honestly, I don't even know what a shore reading is. (I'm a rubber tire guy).

We only use foams at this one track, and everyone uses Active Hobby brand, as they are local.

I'm looking at a brand new set, and on the rear tire package, it says EP37W26R.

EP=electric power

37= is the compound

26=width in mm's

R= rear

The rears are made with stiffening ribs that go across (like a paddle tire), and the fronts are made with the ribs going around like rings, if that makes any sense. These stiffeners are very thin (can hardly see them), and look like some sort of nylon materiel.

Still not sure what a shore rating is though.

What would be best for a tennis court surface (foams), and what rubber tire compound would be closest to Sorex 36R's? I've love to try your products here in Japan.

v/r,

- Paulie

The Shore rating is the hardness (the 37 number on the Active foams). I think our 3038P (front) and 3138P (rear) would work well for foams. As far as a substitute for Sorex 36's, we don't have anything that hard right now. You could try the Blues, but I doubt they will work as well. Just remember to change the setup if you do run our rubber tires. More camber is a must.

Ahh, got it. Never hear the hardness referred to as shore rating before. Thank you so much for the info Sir.

The surface where we run the Sorex's on is a semi prepared parking lot dedicated R/C track. I used to run Sorex 32's all the time, but it's so hot here in Okinawa Japan that they get greasy after 3 minutes. The Sorex 36's last the whole time and get about the same traction.

When it gets cold (at the start of the racing season) I just may have to try out your Greens or Blues.

As for the foams, thanks for advice. I just may have to get a set of them. Do you know if they will clear the Tmiya TA-05R? I have to run 1.5mm spacers on the front and 1.0mm spacers on the back for the Active Foams to not rub on anything.

v/r,

Sorry, I do not know if they will rub or not.

I run them on a TA05R and have no clearance problems at all. That's with no spacers also.

Yeah a lot of foams don't work well on the TA05. You gotta run them wide and cut down the camber link ball to prevent rubbing. Rubber tires are fine.
