MetalMan; yeah, I've been taking a good look at the Mamba Max controller. I like the low internal resistance of 0.0003 ohms - won't heat up much. Not to mention the programming options.

Squee, that's what Mike said. Argg, but those LMTs are pricey for a cheap Jato. What are those CC motor equivalent to quality-wise and efficiency-wise (LMT, Lehner Basics, Wanderers, etc)?

So, it looks like I'm gonna get a motor (whatever thay may be) with a kv of ~4600. So, either the CC 4600, LMT 1920/7, or Lehner Basic 5000. No matter, it looks like it'll be a while before the CC stuff is readily available, which will give me time to scrape some cash together. In the meantime, I can work on the other parts of the Jato.

CC hasn't posted any sort of efficiency numbers for their motors, but the efficiency is definitely up there. The Lehner is most likely more efficient simply because of the segmented rotor.

Well, I've decided on the 4600 system. The price is just too tempting to pass up. I can always get the 1920 later if I don't think the CC4600 is working for me. I just wish Mike would list it so I could at least enter a pre-order or something.

With the exception of the motor mount and a couple of small details, the hard part is done. The parts I posted earlier are painted black now and have the proper foam padding. It looks SWEET if I do say so myself. I don't know if I'll want to drive it! No new pictures though until it is fully done.

Thanks all for the suggestions. Sorry Mike, but I'm sure someone will pick up those 1920's (especially now you listed them :)).

Got the steel CVD kit and installed it today. Looks nice, but what a PITA to install! You have to replace a set of spider gears and get a itty bitty c-clip on the end of the gear/output shaft - which was fun trying to do inside the deeper half of the diff. :mad:1

While I was at it, I put in some 50k diff fluid.

The Jato diff should be pretty sturdy. The flex found in most diff cups (which destroys those spiders) must be all but nonexistent since the ring gear acts to stiffen the walls keeping them from flexing.

Thats not to thick? Maybe you can use a Revo aluminum diff cup? The appear to be the same correct?

Nope, not even close. Each half is sorta cone-shaped. One half is a little deeper - that one has the ring gear. So, the ring gear wraps around the diff making it sturdy. Looks sturdier than a Revo diff. You can see what I'm talking about here and here.

(Edited to answer your edited question :)): I don't think so, but time will tell. Stock 30k seemed way too loose. I guess I'll find out when I get this done and try to turn! I used 50k mainly because I had it. I forgot to pick up stock 30k diff fluid while at my LHS. :(

Yea, I realized that after I looked at the exploded views on Traxxas' website :007: :013:.

BrianG · 07.29.2006, 07:09 PM

lol. I was wondering why you asked that. I figured you wanted me to do all the "hard work". :027:

Mike.L · 07.31.2006, 10:37 AM

surprise us brian!!!!!

BrianG · 08.02.2006, 11:59 PM

Well, now the Jato is done! All I need is a motor and ESC and I'll wait for the Mamba Max for that. I'll post a picture sometime (if my semi-broken camera will let me) because it's just soooo pretty that I have to share! :004:

So when do I get to see this thing on the track at hobby haven?

BrianG · 08.03.2006, 09:26 AM

Actually, the Jato was more for parking lots and such. At some point I'll get specific on-road tires or maybe the 3.3 Jato tires since they look cool, but I guess I could take it to a track once or twice. I still need to wait for the Mamba motor/ESC to become available though.

Do you work at HH, or just hang out there a lot?

Mike.L · 08.03.2006, 04:22 PM

Brian use the victory tires for on road and count how many runs it takes for your bl to burn the rubber right to slick. Any you got some road slicks. No money wasted lol.

squeeforever · 08.03.2006, 04:27 PM

I would just get the Anaconda's.

BrianG · 12:37 AM

A couple pictures of the finished product sans motor/ESC. When are the Castle Creations Mamba parts going to be available already! Arggg!

Anyway...

I ended up creating the motor mount to work like stock. Creating straight sliding slots with a dremel is MUCH easier than trying to "machine" out a motor adjustment like on the e-maxx.
