Some Ta01 Questions....

[Brooklyn Nights]

Hi all.

Can anyone tell me how good the TA01 drivetrain is and roughly what kind of power it can take through it? Are the gears upto high speeds? (I know it has the metal gear attached to the spur gear and the metal idler gear that joins that to the diff and I already have the thicker prop shaft between the two gearboxes so I'm thinking it should be ok?) Now I'm not talking brushless here as I dont want to go down lipo road and silly money street. I was thinking 15t or less (if possible?)

Also as I've only ever bought and acquired the off road form of the TA01 chassis I'm wondering how I go about setting the dampers up for on road height? Is it just a case of different springs and putting a tube inside the damper on the piston to limit travel or is it more than that?

Id definitely get all plastic gears in that gearbox. The alloy ones will wear very quickly with a 15t motor, Id upgrade them to a TA02 gear set. Also make sure you get a hardened pinion gear, robinson racing make some good ones, Id go somewhere along a 16t or 17t pinion., i maybe a bit out but its arounfd that mark Rich. And make sure you get metal bearings. As for dampers Id run some cva's or df03 front dampers in the front and rear.

The TA01 gearboxes are fine with brushless or low turn brushed power as long as you get all the aluminium gears out of the driveline. Use RW Racing or Robinson Racing 0.6m steel pinions and TA02 all plastic gearsets. I run 5700Kv MambaMax on 7.4v Li-Po in mine (TA01, TA02 and DF01 - all the same gearboxes) with no problems.

For onroad use with tourer sized wheels (1.9s), the available ratios pretty much means there is no limit to what motor you can fit to it.

Fit full bearings of course, TA01 or DF01 sets will fit (Red plastic steering knuckle with 2x 1150 bearings is TA01).

By 'offroad version of the TA01' I'm assuming you mean the rally versions and not the DF01 long wishbone buggy version. If so, adding some spacers or o-rings inside the damper body is all I have done to limit the ride height from rally to onroad use. Slightly heavier damper fluid to match. Having the dogbone/universals parallel to the outdrives I find is the best ride height to run them at.

df03 front dampers in the front and rear.

DF03 front dampers are too long for a tourer/rally. They will fit when you use the combination of tourer damper tower and DF01 buggy wishbones (wide track TA01/02).

[Brooklyn Nights]

Thanks for the info guys!

I already have a full set of bearings for the TA01 and also a spare set of all plastic gears. I also have a set of speed tuned spur gears which if I remember right are 66 tooth and 68 tooth instead of the standard 77 tooth spur and I was going to run a 21 tooth pinion gear too. I have the 69 tooth and 22 tooth spur and pinion gear setup with a 21t motor on an off road rally TA01 and it wheelspins all the wheels on dry concrete!

Yes I'm talking about the touring cap style and not the longarm buggy type. I actually didn't realise that the wheels were a different size to that of the rally cars!

Ahh my bad..I thought they would just fit...thanks for that...I just new someone that used them but didn't no you needed the tower and wishbones....cool.

[TA-Mark]

The Speed Tuned Gearsets are 66T and 69T and really only usable with 27T/Sport Tuned/26T GT Tuned type motors. The standard spur is 74T.

Using the 74T spur and 19T to 21T pinion would be around the right ratios for a good 15turn brushed. 19T pinion giving more acceleration and the 21T pinion giving higher speed.

There is a difference in overall wheel diameter between tourer, rally and buggy. Overall wheel diameter makes up part of your gearing and is critical in choosing the right ratio. Buggy is 85mm. Rally is 70mm. Tourer is 65mm. That is assuming you are using the Tamiya rubber tyres that would have been supplied in the kits.

Oh speaking of damper towers I intend to use either a FRP rear damper tower or an alloy one from asiatees because I need to mount the body mount posts on the other side of the damper tower and these will allow me to do that and fit the shell I plan to use. Not sure if this makes a difference to the rear damper setup?

If you use the GPM CF or alloy tower you will also need the adjustable upper and steering link sets to keep the toe and cambers in check as the geometry is different for the upper link holes compared to the standard plastic towers. The damper length for tourer is the same, these holes are in the same location as the original.

Excuse my ignorance here but is that the same for the FRP tower too?

Ah thanks for putting me right, I couldn't remember off hand.

I've not tried the Tamiya FRP towers with standard solid upper links. The only model I have the FRP plates on is a TA02RS and it has the adjustable upper and steering links. I would think it won't work as the solid upper links use the stepped screw and the FRP plates need ball screws/nuts and ball cups.

Ta-Mark is right about the FRP towers,they are very slim compared to the orig plastic.

even GPM's alloy towers arent really thick enough to take the step screw for a plastic top arm.(with out needing spacers etc.)

if you plan to get the FRP/carbon GPM's,try and get/make adjustable top links.

Tamiya do there own brand of FRP towers and adjustable links (labeled 4WD touring and rally) there more expensive than GPM but they come with all the little bits ness to fit them correctly.

If your up to a few home made mods then the GPM stuff is great (and easy to find)

[pikachoo-75]

nearly forgot..i have owned GPM alloy towers in the past...if you want to keep the solid top links then they are fine...i found if its all orig (hub,wishbone,top link) then the step screw for the top link fits well enough in the alloy tower.

I swear i DONT work for asiatee,s but if your after on road and you aint got your shocks already...the 55mm oil dampers they do,look pretty good for the money

Tamiya's FRP towers come with the hardware to mount the solid upper links, as depicted in the instructions:

[pikachoo-75]

Many thanks OCD,ive always fancied a look at the Tamiya instructions for that exact part.through experience ive found Tamiya realy are "all inclusive" when it comes to their own hop up.

Due to the GPM and Tamiya towers always being shown in there packets,its hard to see if you get all the ness bits and pieces.

I know the Tamiya top link packet has the same set up..kinda special sized step screws to fit perfect thru the FRP and attach to the ball nut they supply.

The GPM towers (alloy and carbon/FRP) seem to have a bag of collars and screws? my alloy ones had screws and collars for the shocks only? perhaps their spec changes (luck of the draw) as to what comes in the pack.

The Tamiya's are more expensive for a reason,but the chance of FINDING let alone affording a front FRP one is slim.rears are not so bad? JR-RC has some for a tenner-ish

[HunterZero]

Yeah the TA01/2 rear FRP damper stay sets aren't too hard to find, but the front set is very rare to find.

It's a very common problem for the TA01/2 gearboxes to crack around the screwholes mounting the shock towers, especially if these screws have been overtightened. In fact, the whole gearbox suffers if the screws are overtightened. A TA02 I picked up 2nd hand had cracks in every single red gearbox part due to the bunny who put it together overtightening all the screws.

Don't forget to get an alloy motor mount to replace the made-of-butter plastic one.

This is some really excellent advice guys thanks!

Yes I've seen the gearboxes suffer from overtightened screws from ones I've bought off the bay. Worse still is when people use screws that are too long! Makes you wonder sometimes!

Anyone have any good suggestions for a good quality motor that fits my needs I stated above?

Cheers

[redzone]

honestly, get a 13T 35a ezrun combo, these things have about the same power as a 19T brushed but are way more reliable and infinitely adjustable, and for not much more than a quality brushed motor on it's own.

and no u dont need lipo's to run them..

Well I already have an unlimited esc so I just need a decent motor now.

Ok I have bought a tamiya FRP rear tower to solve the mounting problem so just waiting for that to arrive now. Would love to get a front one to match but as already mentioned I think there hard to find!

I may invest in a graphite one from aisatees to try and match in.

Well done,Brooklyn Nights.The Tamiya own brand rear tower is gonna be sweet.You can be sure that it will fit on a dream.

It is a shame the fronts are so rare,but the GPM front for a TA02 (i know that there should be NO difference) looks spot on. the pic for Ta01 seem different? same with the rear?

im also guessing the GPM quotes a colour? poss for the alloy bracket that attaches it to the front gearbox.best check with listing..a choice of blue/silver ? just incase.

Yeah I noticed the colour choice and it did puzzle me, but what you say about the bracket makes sense though I'll still check before buying.

I didn't actually look at the TA02 stuff! Dont know why as its the same chassis really. I'll have a look when I get 5 mins. Thanks for the heads up!

What exactly is the reason for using the alloy motor mount? See what I'm thinking is that it just screws in to the original plastic gearbox so in my head I cant see it really doing a lot.... Doesn't it just put more strain on the plastic gearbox it is attached to? I've used the plastic one for years without any problems. Can anyone advise me on this?

Cheers

Rich

[pikachoo-75]

Hi,Brooklyn Nights.

you're right.on paper the plastic one seems fine.i think the main advantage of an alloy one is durabilty.

the plastic one can crack due to heat from better motors making it brittle.it can strip its threads and worse case..snap and let the motor fly out while running!

to avoid the confusion of the GPM versions,and the random fit and finish,i would whole heartedly recommend the Ta01/2 alloy motor mount made by Pargu2000 on ebay.

i have one of his..EXACTLY the same as the orig.this means if you want the speed tuned gears then its all as per the instructions.

I had both a standard and modified by GPM and neither fitted well at all.in fact the modified was miles out.not for the mesh of the pinion exactly,it was more the fit into the gearbox.this poor fit translated as an angle on the pinion to the spur and it ran tight ...till it mangled the pinion and spur (single run on a sport tuned)

incidently the GPM "modified" means it is designed to allow "speed tuned" ratio's with out the speed tuned spur?...on road possibly an ok idea....off road (with bigger diameter wheels) not that great an idea either.

had a look on ebay for Pargu2000 he currently doesnt show listing for his alloy mount...perhaps an "ask seller a question" request and he'll be able to sort you out. pretty sure his mount was 10-15 quid
