TA05 Gear Diff in TRF511 [Archive]

Does anyone know if this will work? I know the 416 diffs are way to wide but the TA05 one looks much narrower and doesn't look to take driveshaft blades

I'm not sure.

I just have two spare diff's and swap them over as and when I need to.

They do fit even though they're a bit narrower than the 511 diffs. They take blades however, but there's a guy here who's supposed to explain how he used ZX5 RTR wheel axles to make outdrives that wouldn't take blades. Still waiting on that though...

One of the guys i was racing with last week had these in his TRF511. I don't know what difference they made but he was really happy with it and his car looked good out on the track. Just need to see if there'll ever be a version for the TRF502. His name's Donutt and he's in the tamiya forums a lot.
Hope this helps

The spec r did has been out for some time for the 501/511. The new ta05v2 gear diff from tamiya should also fit assuming it's the same. I am stripping my 501x down this week so will check the STD ta05 dif fits.

lol Thanks Scotty! I wasn't quite ready to open Pandora's box yet...

Too early/too little testing, but I'll post once I've got something concrete.
I've fitted it with shims to take up slack, 1000wt oil and standard 3mm blades.

Sorry for this :D but since I put a diff gear in my Losi 22, I am really happy to not have to rebuild my ball diff after each afternoon... (my favorite track has a lot of grip, and diff is very sollicitated)

If I understand well, I just need to order a TA05 Spec-R gear diff, and blades to put on my driveshaft (do you have a reference to recommend?)

Donutt

21-06-2011, 10:50 AM

XR305240 Xray 3mm blades (for the older XRay T2, up to '007) should fit.

I actually used the 3.5mm ones from a T2'008 and sanded them down slowly so the pin hole remained in the centre - long job, but I'm cheap(!) and had them spare in the pit box.

I'm testing again this week in wet, and early next week in dry (hopefully), so will be able to dial-in a couple of setups. Will post when I get that done.

I'm also udpating our LapAnalysis system for the remaining Scottish Off-road rounds tonight, so you'll be able to compare my laptimes from rounds 1, 2 & 4, with Scotty's from all 4 rounds so far, and see the changes - I ran the ball diff in the 511 at rounds 1 & 2, missed 3 and ran the gear diff in round 4. Scotty has run the 502 at all rounds but TBF has been running the car a year less than me.

Results are at : www.sorcinfo.org/results
LapAnalysis will be at : www.lapanalysis.n-esystems.com
and there'll be a 2011 section for the Scottish Off-road there this evening (late on - give me time!)

Do you use the Tamiya blades? On my TC running Fast motors on high grip they last a couple of months.

Thanks for the info - I'll check the wear tomorrow and update this thread.

I'm with Fab on this one - wear in the 4WD off-road might be more than a TC.

High grip Off Road is at least 5x tougher than anything on road, simply because of jumps and rough terrain. Like I said, 3 laps and the blades were no more.

Yep Dom, you've had the 511 a year longer than me with the 502. Your car's looked good at all rounds you've attended.I didn't know in the A Final 4WD overall at NORA i finished ahead of you, honestly thought i was behind you.502 going great for me so still not tempted to swap my TRF502X for TRF511 but gotta honestly say yours goes really well and handles the track really good.:p

Poor first run and mediocre 2nd run in the 2 finals.

Down to a mechanical issue, that I'm not prepared to admit to on a public forum.
I'll tell you all about it next time I see you.
Only found out on the clean down on Monday.

Cars are still not ready for practice this week; will do my best to get out for a practice run on Friday at NORA.

Well as I can race for 15 meets (minimum before i change them) thats 75 races at 5 mins each.. so thats 375 mins.

You said 3 laps, so if the average lap time is 20 seconds thats one minute for off road

so we can deduce that Off road is 375 times tougher than on road!!!

;)

Seriously, did you use the Tamiya ones? the 3 racing ones don't seem as durable

Donutt

23-06-2011, 09:42 PM

so we can deduce that Off road is 375 times tougher than on road!!!
it appears we may just assume that!

6 races last Sunday, and I've just managed to have a look at the blades.
I say "blades" - I mean "blade".

The one that was left, was hanging on just, cracked and shattered.
The other, must still be at the track.

I think I'm going to have to investigate new outdrives for the gear diff...

Reason: I reckon the off-road cars wear out the blades, probably cause they have more torque applied through higher grip tyres, and much further suspension travel plus the increased forces applied. That must equal 375 at least!!!

Summary: unless you've got unlimited supplies of driveshaft blades, stay clear from this for now...

If that is the case you will probably start eating gears in the spec r diffs, in mod tc the gears wear fairly quickly

I know people have there own opinions with geared diffs, but I ran the TA05 Spec-R geared diffs in the front and rear of my 511 today attending the TORCH Club Summer Series championship and I was very impressed with the results.

The track itself is a large, very high grip and bumpy astro turf layout.

The diffs drop straight into the 511 with a 0.2mm shim to take up the slop on the outdrive bearings. I used the HPI shims from the TC.

3000wt in the rear diff and 15000wt in the front. No leaks or issues with diffs all day. Completed practice, 4x heats and 3x finals without fault.
Used Tamiya TC driveshaft blades (3mm). Good news, I had no wear on the front blades all day, with the rears taking a little more wear. I think this is due to a lot more movement of the rear suspension, hence movement for the blades to cope with. They lasted 2-3 runs before I chose to replace them before breaking or completely wearing out.

Car seemed to accelerate harder through the corners, especially under power. Drive was much quicker.

Considering the high grip and bumpy track, diffs performed without fault and consistent performance throughout day. Very happy and will now start to experiment with diff oil wt's to enhance performance.

This is only my experience with the diffs, but impressed so far ! :thumbsup:

Donutt

27-06-2011, 12:56 AM

Good update Moggers.

I might give the Tamiya blades a go. I also really liked the gear diff in the 511, and am concerned the blades I've been using might be too weak. I'll know better after this week - more testing and will check after every run, see how they are lasting.

But 3 runs per set of blades does seem little extravagant - I think I was hoping for at least a meeting or two out of a set of blades at the very least.

I mean, the ball diff does handle very well. I'm not sure if the benefit of the gear diff is worth the extra worry, and "every run checking" of the blades. But I'll keep playing with it too.

That is, until the internals collapse! LOL!

Guys

If there is enough demand I will get drive cups made by RW Racing that will do the job, let me know, also price is unknown as present, but will alter depending on how many in batch. My guess anything for a full set 2 pairs (total 4) 15 - 20 quid tops maybe less.

I will be having some made no matter what but would not want others with there 511's/501's to miss out.

Correct me here cuz I am a little bit confused. There will be a re-release of the 511 with gear diffs as far as I know. Right?
Could it be with a ta05 geardiff that has got different outputs so blades wont be necessary or will there be an all new diff altogether?
Either way I am extremely hopeful it will arrive soon so I can start race it:)

I've been running the (admittedly) expensive Pumilio Design geardiff for the 511 for about a year now, only changing oils every now and them.

DB01 and 511 always shared the same diffs.
42213 should be 511 kit with these diffs.

51472 & 51470 are spare parts for the diff.

Also, I thought DB01 had plastic outdrives..do you know if the above parts are metal?

What I meant was that DB01 and TRF511 has the same drivetrain so also the diffs are interchangeable.

I'm sure the diff is just like all the other Tamiya gear diffs released (TRF417 model, TA05 model, TA06 front), i.e. white with the same gaskets, o-rings, shims and everything, just different housings with the right amount of teeth and the pulley in the right place (widthwise) and outdrives that fit the model in question.

So these new diffs for the DB01 and TRF501 & 511 I'm sure will have steel outdrives. Also don't get hung up on the DB01 name, Tamiya just always put a model in the product name, but that does not mean it is just for the DB01, e.g. the TRF417 has many parts which are TA05... or TA06... something

Dunno the facts on the 42213 kit with diffs. Seems it has been delayed? But with these diffs to be released in October maybe that's the reason...that they were delayed and therefore the kit. Alternatively maybe Tamiya did not get enough pre-orders to warrant a production run yet....

DaveG28

07-09-2011, 07:36 PM

I'm used to them using DB01 on the part names (from all the arms/double slipper etc), I was just unsure if 42213 is a kit, or a 511 version of the diff, as some websites definitely show 42213 as just the diff, not a kit!? So although I know a db01 diff fits, it's whether there are 2 specs! I'll assume not, and the site with 42213 as a diff only is wrong!!

I guess what I am wondering is, surged they are taking existing 511 stock (more recently came to market) and just adding the diffs. Explains price as well as it probably still has the ball diffs in it, so you get 4 diffs. Not sure it's a "Tamiya" kit per se, anyone confirmed a part number for them?

Agreed! Best thing is buy one with ball diffs and buy one or two of the gear diff units depending on whether you are going to run both front and rear gear diffs or a ball diff in the front and a gear diff in the back like how l'm going to run my 511, and yes the ball diff model is still available.

54329 DB01 Gear Differential Unit

This gear differential unit can be used to replace the kit-standard ball differential found in the DB-01 chassis and 511,502 chassis (items 58395 Durga and 58404 Baldre). It gives drivers another setting option to fine tune their off-road buggy to track conditions. The sealed gear unit differential can be fine tuned using different viscosity weight oils to control how fast or how slow you want the differential to behave. The higher viscosity the oil is the slower the differential is in movement. Compared to a standard ball differential, gear differentials require less maintenance cycles. The unit uses a 37T pulley as well as 12T and 20T bevel gears. In addition, Item 54311 TA06 Cross Shaft for Gear Differential Unit comes standard for greater durability. The Cup Joints included with this item are simultaneously available as Spare Parts (Item 51472).

Specs and Features
DB01 Gear Differential Unit x 1pc.
Compatible with DB01, TRF511, and TRF501 chassis machines.

The plastics hold up to mod TC indoor, so I cant see why they should break.

Oil setup for starters: 5000 front, 1000 rear. I've found this works almost everywhere. Only smooth, high grip TC like tracks may require slightly heavier oils like +2000 all around.
