Ok, naushad bought from another guy. so one is for you.

To every one buying my layshafts. I have deliberately designed this new batch to be unable to slide the 5x10 bearings all the way through. If you want to slide the bearings all the way through, just sand the affected areas a little bit and they will slide through. I designed them this way to prevent the bearing on the spur gear side from falling out of the gearbox and causing the layshaft to not be supported properly. So its normal if you cant push the layshaft further inwards from the spur side. I have already taken into consideration the space that you will need to insert the e clip on the opposite side of the shaft. Conversely, you could always install plastic part TOPM-6, as listed in step 4 of the optima mid manual. You can place this spacer after the bearing and before the inner b4 slipper pad. Just make sure this spacer is trimmed down to 4mm in length.

Also the plastic slipper adjustment tube I included is quite long and once installed on your Mid could rub you rear tyres. The solution to prevent this is simple, either use old Kyosho Optima mid or Lazer ZX/ZXR rims or any rims with similar offset, or if you use modern kyosho rims, cut the tube a little shorter before you glue them to your gear cover. Also remember to flip your rear shocks to the back, like the Lazer so that the right shock will not get in the way of the lengthened layshaft.

will your ZX-R layshaft work with the VTS or B4 slipper setup?

That would be the VTS because welshy40 cant stop raving about how good the VTS is.

Have you made any for the B4? I have a spare B4 slipper I was planning on using

yes I have made one with for the standard B4 slipper. But I think welshy did say that the layshaft can work with both versions, if I am not mistaken, the only difference is the VTS version will have a longer screw end for the spring. I will check with welshy40.

Hi Guys,

I have a problem with the tolerance between the Mid-B4 shaft and B4 slipper plates - I had a real problem getting the B4 slipper plates onto the keyed part of the shaft, it took real brute force to get the back slipper plate on and to remove it now will require a puller - is this normal? I'd have thought it should be a close fit but should slide on and off quite easily - this is the case with both plates - as if either the shaft is too big or the plates ID and key are slightly too small?

Anyone else had similar issues?

Thanks,

Dan

Well it could be your slipper plates are damaged or have seized after some time. its best to put a little oil before assembly. It shouldnt happen to your layshaft as your was actually my personal shaft which I used for a few weeks.
Still, lets hear from those who have bought the shaft if they have problems with the sliding fit of the B4 plates.

I have only just recently assembled the layshaft as per my build thread. I found the inner plate was a bit tight though it does come off by hand. I thought it may have been due to the anodizing. I haven't run the car yet to see if that makes it harder to remove.
One thing I noticed was that I had to assemble the slipper a few times till the spur gear ran true rather than wobbling. Not sure what caused that but perhaps it was related to the inner plate binding

I'm now sorted thanks to my Dremel

The wobble is due to one of the associated slipper plates not being perfectly exact all around as ive had the same issue and bought another section and its perfect.

Any reason I should invest in the v2 slipper plates? I assume the spur and slipper pads are the same between the v1 and v2 expect the v2 is vented and uses a bigger spring & nut?

I'll be running an 8.5 in my modified Turbo Optima Mid Special.

Cheers,

Dan

The fact they look cool should be reason enough. I'm going to get a second pair of plates anodised for my ZXR Vintage Carbon Tub runner

I am running a hobbyking 8.5 too and the slipper and plates do get hot but never melts though. Slipper still holding up after 12 packs of 15 min runs with that 8.5

Jen23 your slipper shaft is on its way.

The optima mid front nylon arms is ready. 4 pieces available for sale.
Each is U$30 a pair includes shipping.

Ok guys, picture of the layshaft for the Lazer ZX / ZXR. Rear one is the very first proto type, second at the very front is the third version. You may not see but there are several differences, we have cut the central block to better position the spur and also changed the design slightly on the one way shaft. Also the end of the slipper side screw thread has also been changed.

Ok the position of the slipper clutch puts the outer section of the VTS just touching the spur cover however that doesn't do any wear to the cover or slipper but you will get some scratching to the cover but its ok. Ive also made a slight error on my dimensions so needs to be updated on the final version. The current latest version layshaft is fractionally lighter than the original which is great as it means less weight and less stress on the motor.

Im still testing and will have one more event in March. Once over Im taking it out of my car and putting into a normal gearbox and will post pictures for you all to see. Then when we have the dimensions exact on the final product Alcyon should be able to sell it.

Thanks welshy40. I drove my optima mid custom yesterday at a 1/8 track and it proved challenging. Flipped the car at a huge jump and first bent a mid top rear shock tower, re bent it and went again, a successful jump and then next another flip, broke a MPP right front arm. That was the end of my excursion yesterday. Damn. I am getting tired of this. On a little positive note however, the modern 1/10 buggies like the ZX-6 and Durango DEX 410 didn't do any better either compared to my ZX suspension mid. Now I use a ZX rear aluminium shock tower at the rear. Hope its good enough to resist bending.
