I will be there for the AOC race, what are the locals planning running 17.5, 13.5 or mod? I myself was planning on running 17.5, haven't run 12th in 4 years. I also purchased some Ultimate tires, looking forward to running them as I have also heard that they are good.

Check out BSR Red and Orange compound rear tires for asphalt. A hobby shop in Hawaii has them in stock here

This compound was used to win the 2013 ROAR asphalt nationals.

The top asphalt racers running 2 cell 21.5 on asphalt a running Team Bomber medium fronts and medium rears or medium fronts and medium soft rears.

Please remember 2 cell 21.5 is equal to 1 cell 10.5.

They sauce the inner most edge for 1 min and the rears for 20 mins. But, you'll have to do some testing of your own to dial in the steering your like.

Google "Team Bomber" and you'll find asphalt set ups using such tires. Also, Team Bomber is cheaper than Ulti..

We have some vbc, could xray's, couple yokomos, a few rcx's and a few ae's.
Do your homework and find one you think you like and can get parts for.
Ren at rab will carry vbc parts.
Thanks again

The thing about the pink/magenta/purple family is that they have a lower rubber content than the foams specifically designed for asphalt racing. This means that, particularly in low traction situations, they won't soak up traction compound quite as well and won't offer as much grip generally on asphalt.

Of course, the yellow/grey/black family has an even higher foam to rubber ratio, which is why they are good in over-gooped black line carpet situations compared to pink/magenta/purple.
Which ulti's are you running?
If you pushed like crazy going to these then you had less grip! Maybe that was a typo?

I actually brought a 13.5 for my car when I first got it, but could never get anyone to run with me! So I went mod.
I think perhaps after the AOC, maybe some guys will keep 12th up and we can run some stock as well.
I think we just need some time to brew.
After the success of last years AOC it was obvious that alot of people wanted to run the 12th class but did not first time round.
Running two classes caters for alot more drivers and their skill levels also.
Scotty was talking of running two classes next time around and even running himself!

SO, now is probably the best time to discuss or propose a stock class to be run at this years AOC event.
10.5- 13.5 1s is good fun (existing format)
17.5-21.5 2s is similar (needs 2s 3300 ish batt- 70-80ish fdr, an existing 2s esc, choice of kit, no booster- in an 8min run prob only 1800mah per run)

Im having good runs with the ulti's in Y, J and X compounds - you pick the hardness according to available traction and required steering levels.
Gluing the donuts to Yok rims is almost fun too (i just do 15 sets at one time with contact glue for centre sections then peel back edges to super glue, the finish is like factory after truing).

regards
David

I think 17.5 would be way to slow on this track. 10.5 or 13.5 would be the way to go.

What I meant was that originally I only tried the Ulti J-soft *rears* while still using the Speedmind fronts (that I usually run with the grippiest Speedmind rears), and that's when I had the car pushing like crazy.

The Ulti soft rears were better than anything else I've tried by some margin in low grip conditions.

I use J-Soft of J-Med on the rear and J-Med or J-Hard on the front depending upon the conditions.

17.5/2s is faster than 10.5/1s. It's about the same as 8.5T/1s.

I would second that. There's a guy in NSW who has been running 17.5 blinky 2S in the 1S Mod class and doing quite well.

Hi, I am looking for some suggestions for tires.


The available tires at nearby LHS are quite limited, as follows :


Front Tires
Tamiya Standard (#51483) / High-Grip (#54334)
Shepherd Hard (SH12AFH)/Medium (SH12AFM)/Soft (SH12AFS)
JACO Double Pink/Magenta/Black


Rear Tires
Tamiya Standard (#51484) / High-Grip (#54335)
Shepherd Hard (SH12ARH)/Medium (SH12ARM)
JACO Yellow/Magenta/White/Gray



We run at medium grip asphalt (outdoor), which of the above combination would be better ?


Thanks

Magenta/Magenta or Magenta/Pink it really comes down to what motor you're running.
