Ta01 Problems....

[Brooklyn Nights]

Hi all

I have a ta01 chassis that I've just rescued and I was planning on fitting a Lancia Delta body from tamiya! However after trimming the body I have realised that the wheel base of the ta01 is too long. So as I know a ta02 chassis is shorter I was wondering if I could simply buy a ta02 bathtub and fit the front and rear gearboxes to it and if this would shorten it enough for the Delta shell? I know tamiya did a Lancia Delta on the ta01 chassis years ago so I'm guessing the new Delta is shorter as its meant for a different chassis! So what are my options here? Can I shorten the chassis or do I need a whole ta02/ta03 chassis and a different body for the ta01 and if so what body will fit apart from the escort cosworth?

Cheers

Can you just flip the rear arms as discussed above? Just a thought....

Unfortunately not as my problem has nothing at all to do with the body mounts. It is the physical distance between the front and rear wheels that is too long! The shell is a tamiya 1/10 scale Lancia Delta but the wheel arches are about 5 to 10mm short to fit over the wheels. This is why I thought the shorter ta02 chassis is my best bet unless someone knows better.

I think taliesin is right. Check your rear lower arms and that they are angled forward.

The TA01 is a standard on road wheelbase. 257mm

THe Lancia Delta was first released on the TA01.

in my opinion I think that you have fitted ta02 rear arms onto a ta01 chassis. As thge ta02 arms go back a little further. The ta02 chassis lower arms have the bottom link of the suspension fitted just inside of the upright screw pin but on the ta01 the suspension is fitted at the back of the lower arms. You can either get some ta01 lower arms or a ta02 tub and shorter prop shaft. But its eiser to get the ta01 rear arms.

I may even have a set in the spares box.

Can i have a pic of the raer of the chassis lower arms ect to be 100% sure

Ok here you go...

Cant see this small diff working though tbh...

What is the wheelbase of the chassis as you have it built now? What is the wheelbase of the body?

[Dazza1]

Yeah they are the wrong bottom arms pm me your address and I will get some in the post for you.

The chassis measures 275mm from centre of locking wheel nut to the other approx, the shell measures 260mm from a theretic centre of each wheel arch approx. (Theretic as I'm holding the tape in the air after cutting the wheel arches!) So the chassis is 15mm too long it seems.

Will these give me the missing 15mm? (See above)

No, the TA-01 arms will only give you 5mm shorter wheelbase I'm afraid. Compared the TA-01 and TA-02 arms just minutes ago.

EDIT: Sorry, I was wrong! I mounted the TA-01 arms the wrong way around. You will get approximately 20mm shorter wheelbase when you fit the TA-01 arms. Then you will get close to the standard 257mm :-)

This is the article to read: TA-01 vs. TA-02

Thanks for all the help!!

Its making sense to me now and the 20mm that the rear ta01 arms will give is what I need!

Just had a thought about the top arms at the rear (the ones parallel to the bottom ones I need to change)

Will I have to change these also if the ta 01 bottom arms swing further forward???

What about the rear suspention too, will that need altering?

Or do I just need spacers? Just 15mm further forward seems way too far for the suspension and top rear arms I have on now so I'm guessing something has to be changed somewhere....

You currently have TA02 rear suspension on a TA01 (upper and lower arms).

Your solution is to either fit TA01 rear suspension to the TA01 tub (gives 257mm wheelbase), or fit a TA02 tub and TA02 main propshaft (20mm shorter than TA01) to your current setup which will also make 257mm wheelbase.

[redzone]

and the TA02 tub & driveshaft will give you better steering (more weight over the front wheels)

Just looked at the ta01 upper rear arms and suspension someone has on ebay and they are the same as I have on now! So could it be I have ta01 upper rear arms and suspension on ta02 lower rear arms? Is that possible? Whats the difference between the two so I know the ones on ebay are correct and not confusing the issue here! Anyone have pics of the upper rear arms of both ta01 and ta02?

Ok think I`m going to quit on this car now i think...

The rear arms turned up today and many thanks to Dazza1 for sending them to me!

However after fitting them the problem I now have is that the drive shafts/dogbones I had are too long to fit the new rear arms and the suspenson is never going to fit without some bushes that are about an inch and a half long!!

How this is I have no idea!!! I placed the body over the chassis and the wheel base is now right but the rear wheels wont drive as I cant fit the dogbones! the ones I have seem about 15mm to 20mm too long?!? WHATS GOING ON??

Cheers

Rich

[Brooklyn Nights]

Solved why now! I need the 39mm drive shafts not the longer ones I have which are obviously not meant for the touring cars or the ta01 rear arms!

Cheers

It seems I have the ta01/ta02 Hummer rear arms and drive shafts!
