oosh123 - Please see this link. I bought 2 and soldered a wired to them. The wire is what youd use for NIMH or NICAD cells and the connector is lower at the top compared to a Corally connector so is the better of the two.

I can buy you a pair if you want, but will send in a month or so once I have done my gearbox plates correctly then can send in one go. I dont have any spare poles though that are in the ZX-S kit for the gearbox.

So it does, but why not buy the 3Racing (i think) alloy version for the ZX-5 which is coloured as well and identical except for the extra hole.

Where are you from? Are you doing the Area 51 event in January in Silverstone?

Guys,

I am going to re-design the front gear box. It is still costing too much to manufacture. I have gone from $2400 (Molded Plastic) -> $200 (Full Aluminum) -> $70 (Aluminum & CF). I think I can do better. I am already quoting from the darkest corners of China.

But the other parts: rear upper deck mount (normal and welshy's), finned motor mount, belts still have the green light. If you guys are into monster truck and still have the Kyosho USA-1, I am also making the counter gear (which melts or breaks easily) in heat treated steel.

Hey there,

as a long time reader, rare time poster (over at rcz) I can only say how impressed I am with all those new Lazer part designs. I'd love to get my hands on those CAD files and ask around at local firms if someone would mill them for me . But of course that won't happen .

Regarding those designs and heat dissipation: Have you considered a finned design like on this Lazer I once have seen in an ebay auction?

One could also raise the rear top deck connection base and bolt the top deck bottom up like this:



This would increase the connected area between the fins and the top deck mount and "increase the space" below the top deck for bigger non saddle-pack lipos, since you could push them a little bit farther to the rear end.
Of course it would be annoying to assemble into the car and you'd have to consider different upper deck thicknesses. Last but not least Welshy's belt tensioner design would have to be changed, but hey, it would be more blue aluminium

Another question: Did anyone ever considered 3d printing to create some spare parts? There are quite some shops which offer Nylon 12 as material, which might be good enough, at least for some front bumpers or maybe some C-hubs.

so long

So, Welshy, I am just going to wait for your prototype.
Regarding the rear gear box, wouldn't it be possible to do something like I scribbled in the terrible paint art (based on the zx evo manual)? Adding some additional material to the pivot blocks and use full size cf parts on the sides, like you did with the front gear box design?

That is a kewl concept.

But as Welshy stated before, the finned heatsink motor plate is enough.

I see 2 concerns there:

1. Those fins can only be most effective if the base is attached to the motor. But since the motor placement moves if you switch pinions, it may be tough to attach them to the motor and still have no interference.

2. With a fin that big on top of the rear upper deck, the center of gravity may shift upward. Although it's made with aluminum, it will still affect the cog. I would choose a hot motor over more body roll.

That's my 2 cents, but I still have to agree it's a kewl design.

It is possible to do that, but my rule is, if what I designed cannot be retro fitted into an existing RC (in this case Lazer ZX), then I will not make it. Adding material to the pivot block is a no-no. I don't want others to pay extra $$$ for a pivot block that only goes with my rear gear box.

And since Welshy is already working on one. Let's just see how his is first. His design maybe better. *Fingers Crossed*

Im having this gearbox made for the ZXR but will base the bottom gearbox on the ZXS so will be made of plastic. Im still awaiting my bits to arrive and will build. Once I am happy with the CF design I will then have a proto gearbox bottom part made and hope to take it from there.

Well last night i went to club to see the top kyosho guys there and thought my zx was ready but couldnt find enough power and on the infield in certain areas i was quicker but turned out my rear belt snapped again so today ive cut away a section on the gearbox where the third screw thats the lowest of the three holding the gearbox to the motor plate. Ive added a bearing (same size that holds the diffs in place, thats pushing in the belt to make it taught. I did try the zxs belt tensioners from the rear gearbox but couldnt get it right. The only problem i have now is the smallest pinion i can use is a 22 as the bearing just misses my 6.5 but will do until my design is done. Pics to follow.

Cheers mate, if you can find a hyperclutch layshaft that should save the day.

Havent tried it but feels tighter, only issue is I cant use my 5.0 as the big bearing takes up a lot of room. Also ive only got two belts left wont be able to test it until my big race in january. Bit gutted as in front wheel drive in certain areas I was quicker than the top two drivers so would have been a pretty good set up. Still need my gearbox designed and built as the zxs hasnt stripped a belt yet and its got a 4.5 in it and is rapid so cant wait to have that in my zxr..
