Alcyon's Optima Mid and Lazer Performance parts

[alcyon]

Maybe I am getting a little bit too ahead of myself here. Some of you already know I have made several upgrade parts for the Kyosho Optima mid and Lazer.
Here are several I have done and some I am planning to make in the future.
What I have done :
1. OT-85 delrin center gear replacement. I just received these in my hands today and they look good. Will be installing them in my Mid tonight to do testing. price is U$12 includes shipping, per gear.


2. Optima Mid layshaft that uses associated B4 spur gears and slipper clutch.
Progress : So far i have made one working shaft and its in my optima mid custom special. I have had several enquiries by members here to purchase this shaft from me, but seems you guys wanted it quick. So here is my plan, i will sell OT-85's and from the profits i will make about 4 layshafts ready for sale.
I will just keep them and hopefully sell off all. A bit of a risk but i think i need to do this to market it better. making this layshaft aint that cheap cause its made of steel and requires intricate machining.
If demand is good i will make some more. price should be U$35 includes shipping with gearbox extension which you will have modify yourself to fit in.

For the Lazer ZX- I have made prototype shaft with several revisions, and welshy40 will receive a latest protoype soon, specifically for the associated VTS version. If this works out, mass production will begin.

Plans for the future :
1. Optima mid modern oil filled gear diff casings, you will have to purchase Tamiya TRF 417 geardiff internal components to complete your working geardiff.

If this works, I will also make for the Lazer.
2. Replacement gearboxes made out of either white or black Poly Ethelyene, for Optima Mid as well as Lazer (especially front for lazer).

3. High strengh Poly Ethlyene plastic arm mounts for the lazer ZX. will be wayyy cheaper than alloy ones made by Pargu2000, and hopefully almost just as strong.

So, just to gauge demand for these items, just let me know which parts you would be interested in, and do offer suggestions for some parts you want but I have not mentioned. Preferably made of engineering plastic.

I could well be interested in some of these parts

Would it be possible to dye the parts you have made in white plastic?

I have a few other ideas for parts but I may be the only person in the galaxy that wants them so might not be viable to make

I'd be interested in the layshaft/VTS setup for the Lazer as Welshy says this is the way to go, will it still allow the one-way roller for the front belt/wheels?

I'd also be interested in a replacement front gearbox if you remove the bit for the belt tensioner/rolling pin to beef it up a bit. Does that make sense?

Of all the items listed there's only the Lazer front gearbox half that's of real interest. Maybe the Lazer wishbone mounts as well if the price is right but they aren't too difficult to make from a length of aluminium square bar, back in the day I made plenty for others with a drill, hacksaw and file. My Mids and Lazers don't go anywhere near a racetrack so, like the vast majority of owners updated slippers and fluid filled diffs wouldn't be of much interest. Plenty of people would want replacements for the obvious weak spots on the Lazer though.

Im up for the pivot blocks but how strong are they. The pivot block behind the front gearbox needs to be made thicker by 2mm to give more strength as its the weakest item.

What I'd love to see for the Mid, are pivot blocks for the rear atleast that hold the wishbone shaft captive like the Lazer.

Interestingly in some pictures in the Kyosho Catalog the original Mid seemed to have such a block on the rear but it never seemed to make it into production or maybe it was on early kits?

I'd love white gearbox cases for a shelfer mid, and really for anyone that wants to race a Mid Lazer wishbones are easy enough to find seeing as Mid ones are a little sparse but the front gearbox case is hard to find so there is some merit to that piece.

I agree the market for the diffs may be a little small, I'm planning on running ceramic balls in my Mid runner project

After the front gearbox, that pivot block behind the front gearbox is the next most needed part.
A guy on eBay had four sets of pivot blocks but all four had that one missing!
Reminds me still need to replace the one behind the gearbox in that "NIP" set I bought on here that was missing that particular piece ...
