I Have A Tb01 & Tt01 Why Is My Tt01 So Much Faster

[hoppi05]

Hi guys, I have a TT01 which i think has the gear upgrade (which i got from tamiyamonkey) and a TB01 which i won on ebay a while ago now both have standard 540's in but the TT01 is a lot faster! the TB01 just runs out of steam very fast, it accelerates to top speed super quick but the top end is very poor! i have a pic of the gear on the TB01 but it has no markings? could anyone work out from this pic what turn it may be? also what is the idea turn for a TB01

Both are ballraced

Cheers

Gears doesn't have turns, motor have (stock silver can is 27 turns) but they have theeth and you can just count the number of them by sight (could help by marking one of them so you know when you have gone one revolution)...

Looks like our delightful stock pinion on the TB01.

its whopping 16 turns is good for a 10 to 1 ratio which leaves it well behind to the stock TT01 at 7.5 to 1 and even lower should u fit a larger pinion.

My advice is a 20 tooth pinion on a 58 for tarmac rallying and perhaps even lower down to 21/22 if you are a little more open and with something greater than the stock motor.

Also the Tb01 is a heavier car by 200grams and has a steel drivetrain thats has a much higher rotating mass than the TT01's nylon gearbox. My advice is to get the lightweight nylon gears for the Tb01 tho keep the stock driveshaft as the alloy one can wear out on the rear bevel very easily, espically on tight rally tracks where accel/breaking is at its hardest and therefore stress espically on the rear wheels is highest.

You will never really get a TB01 to rival a TT01 in a straight line as a TT01 is lighter both in overall weight and drivetrain, But it will gain in the corners and espically over the bumps meaning more power on the floor more of the time and therefore more control and a faster time.

remember the pirelli slogan

"power is nothing without control""

hope this helps.

arrr sorry i ment tooth not gears sorry guys ill get used to the termanology one day??? Yeah i think its 16 turn cheers for that wrc action also thanks for the extra info its very helpful. the weight difference is very noticable as you say, i think my TT01 has a 21tooth in it not too sure but i know it came with all this below?... sounds good.....

fully ballraced, parts left over from build, tamiya spur gear set 55t/58t, original spur, gpm alloy motor mount plate, 3racing blue alloy prop shaft, tamiya spur gears included 19t 22t and 23t

could the 58 from the TT01 be used on the TB01?....

cheers

nope the gear is different and wont line up, Ive tried it and its failed so just get a TB01 gear set.

the stock TT-01 one is a 19turn on a 61 (i think) tho they new setup with the option spur gears allows lower ones, Look at your instruction booklet and the extra info that wouldve come with the hotup,

Cheers agaim i will have a look tmoz and see if there is any info with the optional parts (i did not fit them they were on when i got it) but thanks and i am going to get the optional gear set for the tb01....

[hoppi05]

Is this the gear set i should be looking for?

ebay link removed - read the rules

[Wrc action]

Yep thats the set,

If Im correct the stock TT01 spur gear is white nylon the optional ones are black like those from the TB01 (so dont muddle them up or thing will get annoying)

so just take out the 6 screws, have a looksie at the spur and that should tell you, along with the orientation of the motor and the screws used which pinion/spur relationship u are running,

and therefore where the two cars are relative to each other.

Hope you didn't take my reply as harsh...that wasn't my intention...

[hoppi05]

Nar thats cool mate... i did not help by using the wrong terminology, cheers anyway

[hoppi05]

wooo just checked the pack of spare bits that came with the TB01 when i bought it and it got a 55t and 58t spur in there so at the weekend the one in at the mo is getting out of there and the 58 in and a 20t pinion on the stock motor for now

Cheers everyone for your help

Sounds about right, Just make sure u get the right mount points and dont overgrease and that the spare diff gears are clean as a single piece of grit can make the can run very loud and lumpy as well as causing wear elsewhere along with lateral stress on the bearings,

Yeah i did thanks mate, i swapped them over yesterday evening but i only had i 19t pinion so i used that with the 58t spur. i do have a 55t spur what would the performance difference be if i used a 19t pinion and a 55t spur?

cheers....

[Wrc action]

Well for one u are unable to get that without upgrading to the Aluminum metal motor mount that allows you to run those two pinions. There is a diagram of orientations and ratios in the TB01 manual that shows the results u can expect.

For a 19 on a 55 I would expect similar results to a 20 on a 58, which I think is about 7.2:1 tho please check your manual to confirm that.

HI, i have looked at the manual and you can use a 19t and a 58 and use the center A slot for the motor which is the same as the 16t it says its 7.94, also i did not know there was an alloy one for the tb01, i want one lol does anyone know where they sell them or and ebay user?...

the 19t is from my TT01 is that OK?

Well since writing the above i have run the car its much better a little faster but the gear box is noisey when in reverse?... can anyone help? i sounds like its coming from the shaft? or the motor? i am sure everything was installed correctly and had a bit of grease on there? forwards sounds fine all though there is a very very faint clicking?.. i think i will have to strip it down again tomorrow?

cheers for all the help!......

[hoppi05]

hi can anyone help with the above? I am striping it back down now

[Wrc action]

hmm try to rear brace for the rear gearbox onto the main tub.

or the alignment of the pinion gear - is the grub screw just catching the main spur gear? happened on mine.

regards

[hoppi05]

just had all the rear gearbox in bits inc the diff n its mint!? Bt stil real lowd in reverse, forwards is fine?
