Countersteer Gearing Options for Yokomo SD Chassis

Postby danhfvcsd » Thu Jun 10, 2010 3:19 pm

Hey guys - just figured i'd post this up for anyone running a Yokomo SD chassis looking for information on countersteer gearing, as from the searching i did, it was all over the place - this will keep it in one, easy to find spot =)

I am bound to have screwed something up, so please go through it and let me know of any changes or additions i need to make... =)

This will be an ongoing thread, and I will update this from time to time when i can be bothered or find the time, but it will be a slow process - maybe a mod could sticky this sucker? =)

DAMN!! Where was this like a week ago! Haha, this forum/ME needed this. Thank you for this. Very helpful for people like myself just figuring out the gearing aspect of CS. Quick question from a noob; Is it common for people to underdrive the front after overdriving the rear, or is it preference?

-lol- thats exactly why i put this up - i needed it too, cause i'm learning aswell! hahaha

I'm not too sure about your question tho - having only driven my 2.0 setup, i cant really say... I would assume tho, that it's just a way to get a bit more overdrive out of your setup after getting used to the first initial mod in the rear... i really dont know tho - just hazarding a guess -lol-

Nice list Dan, it should come in handy soon to get a higher ratio on my Pro-D. I never realised there were so many options.

As for underdriving/overdriving the front/rear, no-one has been able to provide any solid info on why one is better than the other. I personally have done both to be able to get my car to a reasonable ratio with the gears that i knew were available, i just adjusted my FDR to match and set my throttle curve on my radio to allow more low end response.

I just noticed that the active hobby kts are the only plastic ones :( . I guess i need to look at modifing the yoki diff input shaft to fit my car instead of modifing the gears. Oh well, more R&D :D

that's one thing I need to get round to doing to, is changing my spur out for a larger one and getting the throttle profiles on the speedy changed up a bit aswell...

maybe you could get a machinist to make a custom one up for you man...or have a go at it yourself if you got tools for it... Half pro-d half yokomo hybrid piece... May aswell get a few made and eBay em off - I'm sure they will sell!! :)

I think I could get so much more out of my setup if I tuned the radio (DX3-S). I am not 100% confident/certain of what I'm doing when changing the settings with it. I need much more low end response. I'm getting quite a bit of heat from my spur/pinion. Being that they are the bits that came with the chassis out of the box, would upping the spur size and/or pinion help eliminate that? Gearing is my nemesis when it comes to tuning ANY of my chassis'.

lol taking a week to reply..hopefully you figured it out? but...

to get more low end response/punch...try upping the spur gear size and/or lower the pinion size. upping the pinion will just cause more heat if you keep the same spur :D

sorry man, i didn't catch this either -lol- If you have the Yohomo DP, and you havent changed gearing yet, then you would probably have a 70t spur and the 30t pinion that came in the kit... I'm also running a 70t spur, and still have a 30t pinion installed in my LCG (i notice you ave the 2.0 aswell from another post somewhere), and i don't have heat problems, although my drivetrain is very smooth and free, and rolls nicely even with pinion/spur meshed... Running mamba max and a dirty old HPI/Castle Flux 5700kv motor that was used in an offroader... What esc/motor you got there man?

I'm about to go up on the spur in my setup, and will look at pinions after that... i have been down in pinion size already - but wanna try changing out spur to something around 76-78T now... It's up to you tho man - i'm still experimenting to be honest -lol-

Have a play with your radio man, and esc settings if you can program it... I think you will find tuning through your radio will help alot aswell - play with your throttle exponentials and looks like you have something called "throttle punch" on there too which sounds like it should help aswell =) If you're not quite sure what each setting does - remember what setting it currently is at - then just change it to the extreme opposite of what it is set at, then have a drive - you will see then what it is you changed, and can adjust to suit your style from there - just remember to do this one setting at a time - you also have exponential for steering too which will affect the way it drives aswell =)

Here's a basic rule of thumb to gearing too for you man...

Hot motor, cool controller, cool batteries = undergeared
Cool motor, hot controller, hot batteries = overgeared
Warm motor, warm controller, warm batteries = happy components

Bigger spur or smaller pinion increases torque but decrease top speed.
Smaller spur or large pinion increases top speed but decreases torque.

And here's a link to that information in full... It's off-road forum, but applies just the same =)

Lol, I guess I need to pay more attention to this forum as well.. I recently hosted a session, and a few guys came out that are savvy to the radio jazz, so they helped me dial in my settings. My steering travel, and throttle punch were adjusted and the differences have made a noticable improvement. As for the heat, I appreciate you guys posting that info! I couldn't remember which way that stuff effected the electronics. I'm running a 4800KV BL Excelorin (Losi) motor, and Traxxas speed control. Not the best electronics but they have done well for the past two years. I have gotten up to around 100-120 degrees out of the motor a few times. ESC doesn't get "as hot", as it has a fan working above it. I recently added a fan/heatsink combo to the motor and it gets warm, but nothing like before. I'm going to up the spur soon as well, as my garage course doesn't allow for high speeds, and I could use a bit more torque. We'll see how that effects the heat issues. I'm just glad the 2.0 is meshing perfectly now!

as innnnn, combining say a "rear 1.5 yokomo kit" with a "front active hobby Stage 2 kit"?? and so on??

it would take way too long to do it with all the different possible combos you could have... not hard to figure that out tho for the specific combos you wanna try? They're all listed there on the first page, just mix and match the ones you want?

sorry man - would just take way too long -lol-


@latenights...
Yeah man - it's a bit of an overlooked part of the setup hey - the radio settings can make or break a car hahaha Steering and throttle exponentials/endpoints and all that are quite important =)

Glad the info helped you out man - if you up the spur, expect slightly less heat =)

cheers man, i missed that post =)

I have updated the first post with retailers common to me, that i know have stocked that particular manufacturer's products, so if it isn't in stock on any of the sites listed, they should be able to order it in for you =)

I have recently ordered a crapload of gear from these guys out of Japan, and they stock just about everything, and alot of the harder to get items, become... well - not so hard to get with them -lol- I highly recommend these guys, they have ordered in a few pieces lately for me aswell... awesome service, FAST and reliable, and are super friendly and easy to deal with =)

My question is not Yokomo related but I'm not gonna create a topic for that!

I was wondering how to know if you're setup is underdriving on a belt chassis (a TA05 Square SP type S in my case).

Here is my current setup.

It seems that underdriving has a different meaning then we use it for if i may believe a certain person, but If you know what most people understand in the term Underdriving you should know that your chassis doesn't have it ;) You are using the stock pulleys at the front which means you didn't make the front slower. Underdriving is making the front slower, overdriving is making the rear faster(your case).

Since the front ratio is stock and the rear has a lower drive ratio than stock, what you have done is overdrive the rear. Underdriving would mean increasing the front drive ratio. It is applicable to all chassis.

Hey guys,
I know that this is a relatively old thread now, but I just wanted to post up what I have done.

I am in the process of CSing my Yokomo MR4TC SD SSG Special [Carbon Fibre] and I purchased my kits even before I knew of this TERRIFIC forum :)

The kits that I purchased were both purchased from GenkiDori.com and they were the following kits:

Drift Package Full Counter Solid Axle Set, Rear (FCD 1.8)
http://www.genkidoridori.com/index.php? ... ts_id=1626
*** Please Note *** These kits have been out of stok for some time, but are currently in stock at the moment

Active Counter Steer Unit Stage 2 [GenkiDori.com is currently out of stock of this one, but I found this supplier just to show you guys the kit]
http://www.rc-race-and-drift-japan.com/ ... ts_id=1732

According to the CS calculator, with these particular gears, the FINAL CS ratio would be 2.44.

I have installed both sets and was told that if I installed the FCD 1.8 in the rear, then I would need to install the Active Countersteer Unit Stage 2 into the front. The stage 2 in the front is designed to slow the front down.
To install the Stage 2 kit into the front, I needed to add a small washer onto the drive gear as well as the 4 shims that I had already put on. Before I put the washer on, the front gears would not mesh properly. They are meshing nicely now.

I have only been able to do a couple of 5 minute tests so far and am extremely impressed with the drive from it. Although I do need to do the steering mod, it seemed reasonably easy to drive.

I'd recommend installing the 'Active Counter Steer Unit Stage 2' kit into the front of all CS'd Yokomo SD cars.

it would be a bit much if you are starting out. If the 2.0 gearing in the rear isn't enough then add d-like gears :D

Hey Guys,
I'm currently trying to purchase the full D-Like DL035 aluminium gear set, but all the suppliers that I have found that sell it, are out of stock.

I don't suppose anyone knows where I am able to purchase this set from at the moment??

I would prefer to stick with the D-Like set, but any aluminium set would do right now, as long as it is 40T/12T :up:

CHEERS :mrgreen:
