Found this one which I am hoping is the correct size. This is a one way so would work for me only however I can buy two one for the front one way and swop it around for the rear belt, that is if its the correct size. Any ideas if it is?

so that you will have front wheel drive forward and rearwheel drive in reverse ?????

I believe its actually easiler to design the layshaft with the 3racing one way pulleys.

1. securing one way pulley to layshaft with c-clips
2. ball bearings on either side of layshaft (as it was before)
3. thrust bearing on motor side ball bearing
4. mount slipper plate and spur which have flat surface on layshaft
5. secure both sides, spur gear side with spring, just a nyloc nut on the other to keep the ball bearing in place.

The 3 racing on way pulleys are $16.67 each x 2. Simple layshaft $10-20 or lower (depending on quantity). Slipper plates - RB5's vented slipper plates are $33. but you can get them halfpriced if you don't want the vents.

So the whole design is approx. $60-85.

just my 2 cent.

a little preview



I might just make it and try it out.

Oosh123 looking good...

but why do you want 11 tooth pulleys ???

It was a mistake. Hence, the deletion of the post lol.

Ooosh

ok

do you have any dimensions ???

Nope... I asked 3racing for the dim of the pulley.

going to do some measuring tonight. and will fix the model accordingly.

[rondoolaa]

i got bored the other night so decided to get all the parts off my lazers that are the same colour and put the all on the same car,

some parts are a bit rough ie: front shock tower

gotta be a 1 off i reckon,

i might stick this one on the bay also so i can put the money towards my new car i'm after, will still have about 6 lazers but no red bits left

and yes i would clean it up if i was to sell it, LOL.

cant upload pics for some reason, happens to me every so often on oople, so uploaded them here instead,

Dozy sod, full 4wd forwards, zero rear wheel drive

Basically what i was saying earlier but not as indepth. Im up for testing as well, unsure tho on using kyosho slipper plates as they dont do high torque pads.

How much?

But it's still just 2 plates creating fraction with the pads. if the pads are good, it should slip properly. Plus, when using the RB5 slipper plates, the plates are big enough that it will utilize the whole b4 pad.

The further the plate can reach from the center and the more surface area it contacts, the less tightening on the screw.

Yea, and if you want your car to reverse, then just flip a pulley.

[oosh123]

After studying the layshaft, I realized that my design won't work.

Although the lazer is a 4wd, it's not a 4w brake. While pressing on the brake, only the rear wheels brake. When you are braking, your spur gear and slipper slows down, then your slipper plate. When your slipper plate slows down the pulley which is attached to the slipper plate slows down. If you have a normal lazer, your rear one way bearing will help. But if you are using a LAW-4, your braking relies on the slipper pad and plate. I hope I am being clear about this.

That being said, if you detach your slipper plate with your rear pulley, you will have no brakes at all.

I know welshy doesn't want to use brakes but I want the ability to do so.

I will think of another way, meanwhile let's wait for alcyon

[lllyf]

nice redesign slipper lay shaft

[oosh123]

Okay, I have 2 solutions. No offence alcyon I don't want to steal your thunder by designing another layshaft. But I do believe these 2 solutions are more economic.

The first solution is the one I posted a few pages back. 2 fixed pulleys bind to the layshaft with setscrews. This solution will give you all time 4wd and 4w brakes. I do believe the belts will be very stressful.

If you want to keep the original kyosho concept to have only rear brakes + reversibility + LAW-4's properties. The second option is your choice.

The pulley that is furthest to the spur is a front rolling one way pulley and the pulley that is closer to the spur will have a fixed pulley binded to the layshaft with setscrews.

let me do a little explaination. First off, when you accelerate, you will get 4wd. Your spur + slipper pad + slipper plate will power the layshaft, rotating the fixed pulley & the one way pulley (which gives you 50/50 4wd). When you brake, your spur + pad + plate slows down, but it will only slow down your fixed pulley (which give you rear brakes). Finally, with the same idea as braking. When you reverse, only your fixed pulley rotates backwards. Rwd when reversing is the same as a normal lazer (giving your lazer reversiblility).

How's that? and it will only cost ~$90 USD / 56 quids for all the components (I am learning the lingo as well). All you need to buy from me is the layshaft and you can call kyosho & 3racing for the other parts.

Thank you Liam for finding the pulley for us. If only the side plates of the pulley is blue.

I will try and build both of the layshafts and test them thoroughly.

Its not about stealing thunder or anyhting, i just as any lazer driver, want something we can use. i agree with you on the 2 pulleys, but there is a big problem. so far there are no rc pulleys that are wide enough to place the lazers belt. the lazer uses a 4.5mm width belt and the pulleys must be at least 5mm width. the current tc pulleys on the market are 4.4mm wide. Unless we machine our own pulleys which cost a lot more.

The problem is finding a fixed slot pulley without the chunk of metal on the side so it will fit perfectly.
