Geared Diff in Lupuz/TC02C - Page 2

InsideLineModels · #21 23-01-2014

Hi Clive,

I don't think we've had any issues with our website today. Is it being blocked for some reason?

Clive Loynes · #22 23-01-2014

I will try again.

All working fine but it will not let me order four because it knows that you only have one at the minute.

If you want to send me an invoice for four then I will send the money via PayPal.

Cheers

Clive

PS Do you do a quantity discount? ;-)

I put 12000 cST oil in the diff for the first run (That's all I could lay my hands on) but the posts that I have read seem to suggest that something lighter might be in order.

Is there any accepted wisdom on this?

T-Plates arrived this morning.

Thanks for the speedy service Kev.

I run 2000 in my TM2

Clive Loynes · #26 28-01-2014

Well you know me Tom, I probably couldn't tell the difference!

All three of the units available have now been purchased so the introductory offer of £50 is now suspended whilst I complete manufacture and then figure out how much I should really charge.

BTW I have established that the Durango geared diff will not fit as they seem to use a slightly larger module gear. Perhaps Kyosho?

One question; what is the weight difference compared to the plastic gearbox?
Thx.

First production version of the drive-side casing has weighed in at 14 grams.

Thank you.

I agree!

But then I am biased as it's my blood, sweat and tears that are going into it!

I hope to incorporate a chassis stiffener once I have mastered the art of manufacturing the boxes.

Kusal · #30 06-02-2014

That weight is perfect! and the box too

Now getting scared in running it!!
Thx.

Hi

Sorry for the total noob questions but is this basically a better (because it's hand made in Britain) version of this?
http://www.eurorc.com/product/2254/t...ff-set-for-2wd

If it is can someone let me know what it's for? I did a bit of searching and all I could find online was that a ball diff was "better" than a gear diff... I'm not trying to say that's fact but I am very curious about it. I assume that the gear diff is a lot more hard wearing? Just without the on the fly adjustment you get with a ball diff??

Cheers
Ben

LOL
Not quite. The device that you have provided the link to is the kit of parts that will enable you to put the Team-C geared diff into the variants of the TC02 that have the motor behind the rear axle. There is no equivalent for the TC02C, the version with the motor in front of the axle. And that's what this is.

I think that the type of diff used is a matter of driver preference although there appears to me to be a leaning towards the geared diff on medium to high grip surfaces.

I'm not good enough at driving the darn things to be able to say anything else but I noticed that there was a reasonable outcry for the gear diff to be made available for the mid-motor car and so I set about making one.

I'm hoping that my customers will prove its worth because I certainly don't have the thumbs, eye-sight or reactions to do it.

Certainly, the geared diff is faff to adjust but once you have it set, ie the right oil in it, it is very reliable.

And my gearbox is much prettier!

Samuran · #33 15-02-2014

Ah ha! Thanks Clive, very helpful. I totally agree yours is much prettier

I'm only just getting into RC, well not counting toys as a kid. I've got a mad monkey and x2c roller to play about with but I think it might be a little while till I need one of these.

I have the Lupuz car, so the same as your Mad Monkey.

My original incentive to put the geared diff in was that the ball diff was a nighmare. The M2.5 screw through the middle kept breaking due to something being out of kilter. I eventually machined enough of it away to cure the problem and also made a little spherical seat for the head of the screw to sit on. This stopped the fatigue failures of the screw but by then the casing for the geared diff was on a roll!

Clive Loynes · #35 22-02-2014

The right-hand half of the casing weighed in at 12 grams and unit 001 is in the post.

hay Clive if you want to try different diff oils in your car then I have a good selection with me, so just see us track side

Lee

oh gearbox looking awsome

Thanks Lee,

I have been too busy manufacturing the first batch to think about what oil I should put in the diff itself. It still has the thick treacle-like stuff that Phil sold to me but I do have some thinner tackle now.

I'm hoping that by the next Turf Wars event I will have a sample that you can take a good look at. Unit 001 was delivered today, down at the BRCA Open. Saw a lot of familiar faces, which probably explains why today's Turf Wars was below the 72 limit last time that I checked.

Cheers

I have been asked if this gearbox would fit an Akula chassis and I think that the answer is "Probably" but it will require six holes to be drilled in the chassis and countersunk from the underside.

I don't have an Akula to measure but the attached sketch shows where my fixing points are located.

My datum is the middle of the back face of the gearbox.

Clive Loynes · #39 08-03-2014

Units 1 and 2 are now with their new owners and Unit 3 should be half done this weekend. Should anyone else want one of these then it will have to be on the basis of say £80 for the box, £10 for the T-Piece and £10 for the Rear Brace. If people supply me with the T-Piece or Brace then I will do them at £5 and £4 respectively.

The box itself is still spectacularly under priced but I enjoy making them.

Also, it is possible to modify the brace if you are handy with a Dremel and don't mind if it looks a wobbly.

I may soon also be able to offer a system of anti-squat and toe adjustment for the TC02C and a rear brace with an extra set of holes for the top links.

That's a lovely looking gearbox Clive, great work!
