Vintage help,

Vintage people helpski!

I started some work on the Optima mid I have ready for the vintage season last night. Stripped the original mech speedo out and put an electronic speedo in, all looking good, though that original Acoms receiver with the flying wores really is HUGE isn’t it?

Anyway I have two questions; I need some 2.2inch wheels what fit the kyosho hex (will Lazer wheels fit?, any have any they don’t want?) as we run yellow mini spikes. Next I need to know the ratio of the optima mid gearbox, anyone have a chart? Next what to gear a 19t motor on, I have a Peak Dynasty I think to use (laydown brush thing) if that makes a difference? So then lastly the gears are something unusual aren’t they? If so when I know what ratio to run Ill be on the scrounge for a pinion to suit. It has a Parma K stock in it now which is VERY slow indeed, though the pinion is quite large.

Oh, All this is assuming the mid belt setup should be OK to run a modern 19t? It seems very free with no belt skip at all which is good, gear diffs not so good!

Dan you could cut and shut some mini-spikes......

I have a load of random vintage kyosho stuff, ex optima mid and er optima pro. Used to be two full cars years ago, but now just a random bunch of bits. If you find your missing anything, give me a shout and I'll have a route through. Isn't it 32dp pinions - really chunky ones?

I seem to remember the spur & pinions were something called .6 neither 32 or 48 DP. That was a while ago that I last had one mind !

Yeah it's .6 module style gears on a Mid. (i think) Back in the day you used to be able to get 48dp spurs from RW racing.

I might have some 2.2" wheels in my Kyosho junk box. I'll have a look tomorrow night (tonight involves a 4 hours of travelling for a club meeting)

As for gear ratio's, I found this in Jimmy collection of Manuals. In the bottom right corner of the page it has a ratio chart, but doesn't mention the spur size. If anyone can tell you the standard spur, then you can work out the internal ratio. Hey presto.

Here's an english version of that page

also, here the parts page which shows the spurs gear. If it's a drawing of the actual part, then the spurs it s 48tooth part.

So... internal ratio works out as 4.07 : 1

Not sure that looks right, but it does have small diffs........

19 turn! !!!! If we are running 19 turns at the york vintage meetings I think I will give them a miss - I would rather go backwards from last year to the silver can mabuchi 540. that allows more cars to compete on an equal level - 19 turn rules out anything crap.

I've just got hold of an rc10 diffs a bit crocked, can you get bits anywhere, The bloke gave me a procat and a complete topforce with electrics. Might need bodyshells for the tamiya and schumacher, odd things came with the cars. The rc10 has a new unpainted shell.

Will all be eligible for the york vintage stuff?

[WHITTLER555]

Does the Topforce Run!!!

If so that will be ACE!!

[Stu]

Keith, your a legend.

Get them all running - you know you have the time on your hands now.

[Northy]

Keith,

What gearbox does the RC10 have? 6 gear or stealth? If your not sure take a picture of the gearbox, or tell us how many screws hold it to the chassis.

Bits are still available from the states mainly, or Ebay.

Get them raced!

Keith that top force with retro electrics would get you uber respect.

Have we got a list of people wanting to race?

Hi Dan!
Yes, I put Kyosho Lazer ZX-5 Disc Wheels on my Mid SE. Its the Standard Hex Hub from HPI and Tamiya. When I used to Race my mid back in the day I raced an 18 tooth pinion and a 81 tooth Robinson Racing Spur Gear. The only Problem with the Mid Series is the Plastic Idler Gear in the tranny box strips out so watch the possible failure! I hope you have some bearings in the Tranny shaft and the wheels. You will notice the difference.
Thank You!
