Korey, are you still running the front end mod on your Exotec ? If so 2 deg or 1.5 deg ?

I found my old AME rear tower and I think I'm going to give it a try. With my Exotek I found that I couldn't keep the rear end under the car, hopefully this should help.

What tires are you running and are you running carpet or asphault ?

Thanks Hiro/Korey !!!!

Default internal gear ratio

Just wondering if anyone else has tried this and got the same results.

With the new speed controllers the FDR has gone from what used to be 3.5ish in spec classes up to over 6 and 7. To get the gearing easier I changed from the 18T pulleys to the old 16T pulleys.. with the same FDR the engine was 10 degrees cooler.. I thought the 16T pulleys were meant to have more rolling resistance therefor making the motor hotter. This doesn't appear to be the case well from what I saw.. it was done on different days so I was just wondering if other have noticed this or tried this with the higher FDR values.

Cheers

Many thanks to both Korey and Tommy for the setups!

Tommy, just some curiosity i hope u can clarify

1) why did u use older pro 4 arms? is it simply becos of the durability or becos of it being a better setup for steering?

2) I notice u used standard hex at front, while ure using both FF and FR blocks at 1.5. Tat means ure running wider width at front compared to ur rear. Does this gives u better cornering since its larger track in Poland? If smaller track, will u stil use wider front or narrower front for better steering and reaction?

3) Lastly, are u using the pro 4 UJ which is slightly longer to accomodate the longer width when using the FF n FR blocks mod?

Thank you so much in advance and i wish you all the best in your comin race. Cheers!

I also usually run with un-cut top decks since i feel it gets inconsistent (especially when cutting the front deck). In Poland though i cut the rear deck to get the rear stable since the track was HUGE.

Me and M Vassmar (T3) has had some great racing this season in our regional series but i've always been a couple of seconds behind both on high and low traction. This weekend i took TQ with 0.2 seconds and the car feels a lot more consistent than before. In the finals i had the win until a lapped car spun out on front, we crashed and i had to settle for second.

Another tip i have for you all is something i got told by Hiro, is lowering the front knuckle a bit, i lowered it 0.7 mm.

I went back and forth a lot with this in Poland, i always ended with it lowered since the car felt alot more consistent in the sweepers making it traction roll less.
I also run 2 degree blocks in front, my chassis with steel holders did not have the RF holes drilled so i did them in a mill at work.
A question Tommy, do not understand how could you put the washer 0.75 over front knuckle ... there is enough space, had to change something?

I use xray spindles. They are stonger and they are .75mm shorter so no grinding. Use the forward most hole to duplicate the steering geometry.


Thanks for the set up sheets.

Lowering the steering knuckle changes the roll center slightly. its a small change but its enough to notice it.
