stock jato 2 speed reliable on drag nitro slash?

[snowxxxxxx]

Hi y'all, just made an account as nitro rc no prep has caught my eye. I saw a thread on the Invader and it has got me as I'm thinking about buying a nitro slash. I read about how the 2 speed from the Jato fits the slash with some small modifications, just wanted to know how stout the transmission is. Would it be able to handle some hard runs? I understand it's a plastic case, but hopefully I don't have to source that discontinued Integy piece as that would be tough.

Welcome to RCT! @johnnydmd is the guy you want to ask that question to. I have a Jato with the plastic trans and can tell you fir a fact it's a piece of garbage for bashing. Any slightly hard landings on the rear end of the truck and the weight of the rear tires and such can easily rip the shock tower right out of the trans case, destroying it. That probably wouldn't be a problem on a drag car that never jumps of course. But just thought I'd throw that out there.

Unfortunately as @WickedFog mentioned above-they are made of glass, and are the first thing to leave the chat when you apply any real power to it, or tremendous load… IE-dead hooking from a dig…

Thanks for the info. Yea it was Johnnys thread I was reading, now I want a slash lol. I’d imagine steel gears would help some but just delay the inevitable. Are there any other 2 speed transmission options y'all know about that could fit a slash?

Absolutely, and sorry to be the bearer of bad news… Like you said-the real weak point boils down to the case flexing, and not putting up with heat very well.. I did Robinson Racing hardened steel gearset in a Traxxasss 2spd once with a modified Picco WASP .26 in front of it, and blew the case apart in less than an hour.. I put that “bulletproofed” Traxxas back together with another case, and sold it that week. Been running race grade 1/8 kits ever since.. Now if you were a machinist, and had some time in your hands-you could undoubtedly whip up an aluminum case, and then run hardened steel gearset with good bearings and be just fine..

Bulletproof .. lol. Yea it looks like it may be time to scour eBay, as i’m not no machinist. If I manage to source one I’ll snag it. I may bite the bullet on a chassis and build it up, but it’s just an idea. Thx for the help

Someone could make a lot of money if they re-released the Jato aluminum trans upgrades.

Agreed. I just Columbo’d all my top secret old school parts vendors.. They’re made of hen’s teeth for sure… Found some more 1/8 Panther Gators though…

I sent Integy a request on X to bring it back into production. I am sure they would if enough people asked for it. Vitavon would be a good one to talk into making one as well.

 

[johnnydmd]

As others have said, the weak spot (for bashing) is the shock tower mounts, which in drag racing aren't a factor. If it's going on a Slash, then you probably won't even use the Jato shock tower anyway.

For small block cars, the stock transmission and gears can hold up decently. With a big block car, the gears have little chance of living As for the case, with the steel gears in, eventually the case will die too, from heat, torque, etc. Best bet is to scour eBay every day. Those Integy alloy cases are highly prized. I managed to find my first one after nearly a year, then was fortunate a few more came on the market so that all three of my cars using that transmission now have the alloy cases.

Yea I may just have to run the stock case for a bit till I find one. If someone has a case, it might be possible to re-make them. I've seen people scan and 3D print old car parts, the same concept could probably be applied to R/C. The hard part is the scan. Companies out there will even 3D print aluminum parts for you now. @WickedFog you should make a thread on it and how to contact Integy to bring it back, it'll probably get more people to vote. Did you just email them about it from the contact page?

I went on X (Twitter) and found their profile and replied to one of their posts about new parts.

A 3d printed trans case would likely fail faster than you can print a new one Plus the tolerances wouldn't be that great, and with gears, you need that mesh to be pretty spot on.

is 3d printed aluminum that bad?

 

[WickedFog]

Never seen 3d printed aluminum, but any 3d printed part will still need to be machined for accuracy. Bearing journals would need to be held to about a .0002" tolerance in diameter and position. I managed to get my original CR10 dialed in to .002" in XY and Z axis, but that was the closest I ever got it. Industrial printers can get closer, but even metal prints I have seen in the machining world would still need close tolerance machined in.

definitely agree, bores will still need to be machined for accuracy.
guess i was mistaken and i thought you were saying even the 3d printed aluminum would fail fast.
my brother in law recently got a CNC mill, would be fun building the trans bp in cad to be able to mill it lol dont have a Jato or a Jato trans though.

 

[WickedFog]

It would take some trial and error testing to get an accurate model designed to work, but could be done. That's how Integy had to come up with theirs. I am sure they had a CMM to measure everything though.

 

[snowxxxxxx]

If they become high in demand someone might do it. If you wanna undertake it D3MON finding a jato tranny plastic case is real easy online. I’ll email Integy about it, pray they bring it back lol.

 

[snowxxxxxx]

Well I emailed Integy and.. here.

I would reply back to them...
Well here in the US, since you discontinued that part, a lot of folks have revived their Jato's into drag cars, and the transmissions don't hold up.

And they're full of crap. I know of a few people that have sent them requests for it. Me included, a few times.

We need to start a petition and send it to them.

It's not like they couldn't set the job back up on the mill and whip some out. It would only take a few hours to whip out 50 of them to test the market.
