VDF II CS, tires, and motor setup help needed
#1
Hi guys,

I recently purchased my first drift chassis (Tamiya VDF II) with various Tamiya hopups. I'm looking to place another order to get drift specific items to finish out the build. I need some advice on the type of CS kit, motor, and tires/wheels to purchase/setup. I plan on drifting on smooth concrete (garage) and carpet (local race track). I already have BL motors of various turns (i.e. 25.5, 21.5, 175, 13.5, 10.5, and 7.5).

CS kit: I found a site (broadtech.hk) that sells the CS kits from Eagle Racing in various ratios. What ratio should I start out with? Does this kit have everything needed to setup CS for the VDF 2 chassis?

Tires/wheels: What works on carpet and concrete? I'd imagine that I would need to buy separate types for the 2 surfaces.

BL Motor turn: What do most people run with a CS setup?

A good cs ratio to start out with, would be anywhere from 40 - 60 percent. The broadtech cs packs will have what you need, belts and pulleys. I personally use mostly square pulleys in my vdf II. As for tires you are dead on, carpet requires a harder tire, and concrete requires a bit softer tire, try out some t-drifts on your concrete, someone will have better advise on carpet tires as I don't use them / have a carpet track at my disposal. Currently i'm running a 13.5t in my vdf II but anything from 17.5 - 7.5 would work, all becomes preference after awhile. I'd suggest throwing in the 10.5 turn and see if you like it. You can always swap. With Cs your Fdr will change so make sure you keep an eye on it, I usually keep my fdr somewhere around 7.00. By the way are those sensored BL motors? and what all hop ups have you got for it yet?

Awesome info! Thx Piper! When you say 40 - 60 percent does that translate to 1:1.4 to 1:1.6? Eagle racing has a 1:1.37 and 1:1.59 CS kit. WOW!! HPI makes some very cool drift tires with licensed tread patterns. Do these tires mount directly onto their 26mm wheels? HPI's wheel selection is really nice too! All of my motors are sensored and I'll either put in the Speed Passion Revention Pro or Novak Edge ESC. The Revention ESC is light blue so it'll go nicely with the chassis. However, it has a rather large foot print so the Edge may get mounted in it's place.

Along with the VDF 2 kit, I purchased the following hopups.

Tamiya alum bulkheads (53990)
Tamiya carbon shock tower front and rear (53846 and 53845)
Tamiya alum servo horn (54121)
Tamiya alum bumper support (54128)
Tamiya alum servo mounts (53723)
Tamiya cardan Joint Shaft set (42216)
Tamiya large damper retainers (42192) - I run HPI springs
Tamiya one way unit (53833) - it appears I may not need this if I get the Eagle CS Kit
Tamiya split suspension mount 1A-1XA and 1C-1XC (54172 and 54174)
Tamiya suspension blocks C and E (54071 and 54073) - I also have A, B, D, and F blocks from racing TC

Is there a reliable online store that specializes in drift cars/parts? I had to purchase these items from numerous online stores. I could save a little on shipping and the hassle of searching high and low on the internet to find parts. I'll post pictures as soon I finish building it :)

1:1.59 CS kit would put you at 59 precent cs, I would start there and maybe grab another set for higher Cs for after you get use to 1.59, maybe a 1:1.89 or which ever it is. The Brodtech pulley sets come with just the pulleys and belts, the front one way is an actual differential, you will get a better understanding of this once you put the car together (pulleys are mounted to differentials). As for the hop ups you have purchased, I would recommend buying the Tamiya suspension upgrade, but you have already purchased cvds, and front carbon tower, which it comes with. Either way your gonna need to modify the stock c-hubs and hub carriers or replace them with hop ups for more steering angle, which is pretty essential for counter steer. check out my thread on my vdf II, I just updated it. as for online stores sometimes its hard finding Ta-05 parts I usually shop from these places http://www.rcmart.com, http://www.rc-race-and-drift-japan.com/, http://banzaihobby.com/, http://rc-art.net/index_eng.php, http://www.broadtech.hk/eagleshop/shop/ShopTop.aspx, http://www.stellamodels.com.hk/

I checked out your thread, very nice setup you have there!! It looks like I'll need to order the Tamiya RC Drift Suspension Set (84296) and the Tamiya Ackerman Steering Set (84150). I also found some products from Overdose, their steering crank set (OD1110), C Hub and upright set 8-8 (OD1117), and the 44mm drive shaft set (OD1039). My preference is to go with Tamiya unless there is a performance gap between the 2 products. I've never head of Overdose and wonder if they make quality items. I tend to stay away from 3Racing/Yeah Racing/Atomic products.

I'm going to bolt on the 10.5T BL motor. I can always add more timing on the motor and speedo if needed.

I really appreciate the info guys!! I'm getting a crash course in drifting. I can't wait for everything to arrive so I can start the build!!

Don't bother with the ackerman steering wipers, they are trash. the ones that come on the vdf II are more then functional, lots of adjustment. As for the Tamiya RC Drift Suspension Set (84296) it does come with aluminum C-hubs and hub carriers, and Cvds (drive shaft set), The cvds in the Drift suspension upgrade are Wa aka wide angle, and are very capable, they will give you a lot more steering angle. Overdose sells very nice products, I'm not saying to not buy them, its just there is not much point in buying multiples. Tamiya and Overdose are pretty much in a league of their own when it comes to quality.

Overdose is probably the best aftermarket manufacturer for many RC drift brands

Another thing I should add. You should grab at least 1 Tamiya TA-05 aluminum bulkhead, and put it up front on the chassis because the mounting points are lifted it will allow you to extend the steering wipers even further, it will explain this in the Tamiya drift suspension upgrade

Good to know that Overdose produces quality products. I checked out their stuff for the VDF and it looks really nice! Thx for the info.

I received my VDF II kit and some of the hopup parts (including the TA05 bulkheads). I'm still waiting on the remaining items to finish the build. BTW, I ordered the Active Hobby 12* lower caster blocks, front/rear uprights, and 45.5mm WA Universals to increase the steering lock. As for tires, Jin from Raikou was very helpful and offered up great advice and info on their tire selection. I went ahead and ordered their 3 set combo in various compounds.

The build is going great just as expected. Can't wait to get it finished and go drifting. I'll get more pics up when its completed.
