Hey
guys, got my TA05 VDF in the mail about a week ago. Finally finished building
and modding this chassis for countersteer today. I think this chassis is a bit
overkill for 50/50 drifting, but it is perfect for CS as setup and chassis
balance are quite important.
Very glad that I spent tonnes of time researching and modding my old TA05
version 1. I knew exactly what parts would work and how to mod them before I
even got the chassis. The bulk head, suspension and diffs are the same as TA05
version 2.
I will be covering a bit of the build up and how I modded the parts for
countersteering drifting.
Hope this info is helpful to you guys, let me know if you have any questions.
Warning... long post ahead 
Yes! I'm a tamiya fanboy lol. Packaging is almost like a TRF chassis. It says
'Limited Edition' on the box, but I'm not a believer 
Parts used for CS mod: (40T and 21T pulley were not used)
Stock VDF drive belts
Tamiya 50877 TA04 32T pulley $3.50 usd
Tamiya 51213 TA05 16T center pulley $3 usd
3racing SAK-07C Sakura Zero 22T center pulley $2 usd
3racing TA05 Aluminium Solid axle $12.5 usd
Superglued the CF chassis edges.
Drilled 4 holes on the 32T pulley to match the mounting bolts pattern on the
3racing spool.
Stock VDF 37T Ball Diff. for the front.
22T and 16T pulleys mounted on the drive axle. No modding was required.
128, 120, and 112 spur were included. (04 module gears)
Dual tensioners for the rear belt and single tensioner for the front
Spec-R double joined CVD was used for the front. Stock tamiya universals can't
handle the increased amount of steering and would cause a lot of vibration at
max steering lock.
Spec.R DCJ Universals for the TRF416 Part #: SPR001-TMY
Steering mod: (Sanded down the steering stopper)
Sanded down a bit of the C-Hubs to allow more clearance for the cvds.
Camber mod: (not the prettiest, but it will be hidden anyways lol)
Tamiya VDF's implementation of zero ackerman:
The $100 TRF bling coated dampers
The spring rate is quite soft, but a bit firmer than tamiya's red soft spring.
Quite a bit of adjustments available for the battery tray.
Done!
Stock front and rear belts.
Steering angle with 4mm offset wheels.
Gearing ratios. 39T pinion (04 module) was included.
2.5 degree stock toe-in rear.
My current 59% cs ratio and 5.22 FDR. The CS FDR ratio is obviously too low for
me. Will be changing to a lower teeth pinion and aim for a FDR in the high 6 to
mid 7 range.

few more pics with electrics installed
The rear belt just barely clears the motor with the 22T pulley and stock 128T
spur, 39T pinion. (The first rear tensioner already at highest setting)
