Well, it is very obvious when you tighten the tension by 1 notch, you can feel it is too tight....then back that off 1 notch, and thats it...nothing you can do about it. My TA05R feels like too loose all the time (too loose to my taste at least) but never skip a tooth.....if you still want to adjust the tension, you must add a optional external belt tensioner that has a arm with bearing that can press the belt down for more tension. It should be pretty easy to do that. But I don't think that is necessary....belt tensioning is not a big issue on TA05R.

this is what i was looking at.

Yes...if you need to add one, the NOVAK one is the best. I ran Lipo 3200/4800 on my TA05R indoor, outdoor, stock 19T and 4.5......never used the LIPO cut off....cause I bring the car back all the time after qualifier or race. And at practice, I don't run it more then 6-7 minutes...no reason to run the car untill it is dump, why take the chance when you don't have the lipo cut off.

wow Solara.. how small is the track that you're running on? 7.5 for a stock motor. must be a tiny track.

we gear our CO27s in the low 6s out here. then again, not everybody gets to run on the Tamiya track.

we gear our 23Ts in the mid 5s. 5.3-5.6

i have all the gear together for my ride, i just need to paint up the body and wait for my tires to arrive. when i am try to find some mounting holes for my DNA2 body, i noticed that the wheelbase is rather short for the body. should i try to center the wheels with the center of the body, or center the front wheels only since they are the ones that need to have proper wheel clearance since they steer?

also, i saw that my rear belt rubs on the stock cast motor mount just before the belt wraps around the center pulley. i probably did not see this before, but as far as i know i have built everything correctly. does anybody else's rear belt rub a little bit on their motor mount? is this something to be concerned about?

I set-up the car the way that I want it to sit than I cut the body around the car not the other way around. Is that right?

i'd just like to stick with 48 pitch because the pinions are cheaper and i can get them in 5 gear packs from Robinson.
Here is an explanation. Also tells you how to convert from 48 to 64 or 64 to 48. http://www.robinsonracing.com/tips.html

There are a lot of different sizes of track out there, my local track is that small, & those of us who run brushed stock motors do gear theirs(mostly CO27's) at around 7.3 FDR, so that could be about right for Solara, too....

Default Gearing

Yep I'm geared right now at 7.8 in stock with a CO27 on a 100 by 50 foot track. Temp gets up to about 170 F which is a little warm for my liking, but trying to keep up with the brushless guys.

How hot do people run there stock motors by the way?

Chris,
What would you get a cobalt and a 23 turn at Bending Corners?
Max
P.S. Maybe I should go on Bending Corners thread!

i have not yet run my car yet, i'm just waiting on some tires. but i have no idea what kind of gearing i should have for a smallish parking lot track (about 75 feet by 55 ft). i will be running the stock 105 tooth spur and i am going to try a 26 tooth 64 pitch pinion on a CO27 pro stock. my FDR will be close to 4.0, but i'm guessing my pinion is going to be too big for the track. i've got a 19t, 23t, 26t, and a 30t for now (i really had to guess and buy a few pinions to start off).

Buy a proper 64 pitch spur, the Tamiya one in the kit is not the same. It won't mesh as smoothly(close but not quite). There's plenty of discussion in this thread about mixing whatever it is module/64 and 48 pitch gears..in general, don't do it.

(105/26 = 4.038 x 2.25 =9.08)= calculation for FDR on TA05

I would start with the 30 tooth pinion which would put you around 7.875 FDR.
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! All cars have different variables depending on the number of teeth of the pulley and the center pulley. For example the TA05 pullies are 36 teeth and the center pully is 16, So 36/16= 2.25
Based on the size of you track I would say 8.0 FDR might be closer to what you want. The motors RPM's should max out just before the end of the straightaway.That should get you close to your best FDR on the track!

hey guys,
we use 23T high torque motors (Orion Katana), the others tend to run on FDRs around 5.9 - 6.3, so which pinions and spurs will work best?
Also, does anyone know where i could get setup sheets for a TA05 or TA05r?
thanks
Dom
