Very true. THe ball diff in the FF03 is very similar in build to the M05 and the M05 ball diff is rubbish .. it comes undone all the time

Had it all apart and checked, all parts seem ok.
Only thing I have noticed was that I had put the diff bolt in from the wrong diff half (side with lip) and that the bolt was on the wrong side in the car.

Am now rebuilding taking careful note of the manual (lots of bits easy to miss)

Have also noticed a lot of play in the steering already

Default Just too weird...

I think it's a travesty to match the porsche gt3 shell with the ff03... And not only that, but to enforce it as THE ONLY shell people can run? What? Is TCS sponsored by Porsche?(if it were, that'll be different)
Tamiya makes (and is re-releasing) many awesome fwd shells. Not to mention all the other shells that do actually fit. It doesn't make for exciting racing (or hobby) if everyone races with exactly the same shell... How incredibly boring TCS is.
And also such a no-brainer... Set the gearing, install the silver-can, use the tcs approved battery, cover it with the approved bodyshell... Wow! Let's see... Might as well give them a setup sheet they have to follow strictly...

Yawn.

5. Tamiya 24mm tires and spoke wheels only. (Dish wheels are banned from GT-4)
6. Any pinion and spur gear ratio combo is permitted as long as the gear cover fits. The gear cover must be used. Helpful hint for the Tamiya Track. For a 5 minute race we have found the optimal final drive to be 3.85. The best spur/pinion combo for this is 80/54.

I ran with the Tamiya Vectra, and not only did it perform well, i also had a few of the top modified drivers (Chris Grainger & co) say it looked like a proper Touring Car

100% agree to that. We had the first FF03 race here in Malaysia recently

TAC round 3, 27th June @ RCC, Glenmarie

All the shells looked awsome(thats before we destroyed it!!) in the FF03 class. The drivers to picked up some real BTCC driver names to make the class more interesting.

I picked up this HPI BTCC Mondeo from 2000 series, it is a 200mm shell but was half price, and it has a scale rear wing as well as a racing rear wing.

Just looking at the suspension mounts. FF looks to accept up to 1A, so can work out the rest for extra car width (I don't have to worry too much on width as I am running as a non championship car, just there to boost grid numbers and have fun, my GT car is my main car).

Yes ... small writing in the middle of the diff assembly instructions says ..."turn upside down" ... very nasty trick

finished buidling my FF03 PRO, i have noticed that the steering turns more on the right then in left. once i turn the car to the left, the push rod is hitting the servo saver.

i test run it and has little turning radius to the left.

has anyone encountered this problem? any solutions aside from replacing the servo horn?

Another case of things not being clear in the manual
Looks at the page VERY carefully and you will see it tells you to cut the back of the cup away.
(I missed it also)

Page 15, Section 30, bottom of page.
Where it has the 17mm bit, look to the left and read writing above.

I missed it until I found the same problem

@jebolution,


Did you trimt the servo saver under an angle of 10?
I thought you have to do this towards the steering or to the front of the car.

I had to lengthen the steering rod by 1 turns to get even steering

yes, as per manual.

oh and when i turn right, the front right knuckles is hitting the shocks pushrod too... and if i turn left, has a big clearance. but thats not an issue

i removed the steering rods to check the length and both are the same, 15mm in length.
