Where did you come up with the 4.0 FDR. 26 pinion would put you at 9.0 FDR? You forgot to multiply the variable into the formula!
sorry, i looked at that robinson racing link someone posted and they said to do it spur divided by pinion to get the FDR. guess i was mistaken.

i think i will use the actual 64 pitch 104 tooth spur gear i have because when i ran my car for the first time today, although the gear mesh was fine, it still felt "stiff" and did not roll smoothly. i will also install the 30 tooth pinion as my top speed was not up to par with what a stock motor should be at my track. i might need to get a motor heat sink though because it was getting a little warm. but i really don't know how warm it can get before i should pull it off the track. i have a temp gun, but can anybody tell me what kind of temp i should be running at maximum with 4200s, 30t pinion and a CO27?

thanks

I'd say you should keep it under 180 degrees F(& that would be pushing it a little bit, but it can stand that), & you should always try to base your gearing on how it tops out on the longest straight(try to get it to top out about 80-90% of the way down it), & then make small adjustments from there. Oh, & DEFINITELY use a "real" 64 pitch spur if you're using real 64 pitch pinions.....

we gear our 23Ts in the mid 5s. 5.3-5.6
Yupe...not everyone can run the TAMIYA track every sat, but I am sure you won't be able to run that track for long...so enjoy it. We do have a 1/8th track that is 10 times better then the Tamiya track but running stock or even 19T motor at that track is like watching paint dry....so we did 7700 and or 3.5/4.5 with foams/lipo instead...ALL OUT.

My TA05R using manuel setup was pretty good with rubber (stock) and even foams...however, just cannot run against the top rank car (007, Losi, Mi3...etc) for some reason (weigh, equal belt..etc). I have tried several setups and it just does not get that 1/2 sec or so more............that equal belt design might have something to do about that.

Between 7-7.5 is about right for our track...like 80 x 120...3 rolls of parking spaces parking lot style....the killer part is, all the turns are 90 or 180 degree formed by 2x4s...and they are all painted YELLOW, now....along with the parking stripes are all painted yellow and they look EXACTLY the same as the board....our challenge is...figure out which one is the board and which one are the lines...........the penalty, broken arms and DNF....

no, not a typo, I run the 3Racing blocks, so at the rear, I am running a +1 block, which is a wider block, and it increases the rear toe... confusing I know, sorry.

But no matter that is + or -, are you still running TOE-IN? I have never seen anyone run TOE OUT especially at the rear of the car...
If I am the one to write it...I will simply say TOE IN or TOE OUT 1 degree...

It was written for my info, so the rear block is wider, and is marked +1, but in reality you are increasing the Toe in, not making toe-out.

Thats relieving, I was still trying to figure out how rear toe out could possibly help...

Anyone know off the top of their head what degree toe in the rear blocks that come with a TA05R are set at? I think its 1 degree but Im not sure.

The stock 05R setup uses an A block for the front rear and a D block for the rear rear for a total of 1.5 degrees of toe in at the hingepin. The stock rear upright has 1 degree of toe in built, giving 2.5 degrees of toe in total.
