lucky to have a cool cop at that time. I love when people watch our cars go fast.:D

Hey Brian here's a link to some Jato setups that should get it going better on the track. The Silver State is the Vegas race and the track is usually dry and hard... kinda like Haven's

i believe the link is for revo's?

Update on the Jato:

I don't know how, but I broke one of the cups on the CVD set. This really sucks because you have to take the diff totally apart to replace it. :mad:1

So, I put them back to stock sliders. Ran two packs today at the track (about 1.5 hours) and they held up fine. At least if the sliders break, I won't have to tear apart the diffs!

Glassdoctor: I checked out the Jato setups but haven't gotten around to implementing them yet. I'm actually pretty happy with the setup if I could just get some decent tires. I've worn out another set of stockers. Imex is the only company that carries 2.8" rims and tires with pins and some stuff is out of stock right now. 2.2" rims won't work for me because I'm using RPM arms and you need to do some mods to use 2.2's, which I don't want to do.

What was the top speed of the BL Jato you built? It actually looks real easy to convert not like the Revo which almost everything has to be custamized.

You are right not many people do this conversion, but if I am not mistaen I have heard at least 2 people on these fourms going for this same conversion. All in all i think it would work well, because my friend has a jato 3.3 and it is a blast to drive. Now think about gitting rid of that extra weight and throwing a BL cobmo I think it would be just as fun.

Sorry i am a little late with this Quote on "Quote" I just read the first page I did not see there was nine. Sorry again.

Well, since this has been reopened, I'll let you know Brian that I run 2.2 rims on my Jato and did not have to mod anything? So i was curious to what you mean there. Also, if you shop around, I have been seeing new tires and rims for the Jato that are 2.8's. Or at least my LHS had new kind of 2.8 tires for the 2.8 rims, something like that, but I have seen them.

vette1: Top speed with 2s on the 4600 was ~47mph. I can still add one more cell for 3s, which should bring it up to ~60, but it's already plenty fast for me. This project went from an "on road" project to "on track" project. :) The only local track I know of is too small to hit those speed without spinning out, so I'm happy.

GorillaMaxx360: That's ok, we'll forgive you... this time, but don't let it happen again! ;)

neweuser: When using 2/2" rims with the RPM arms, you have to replace the hub pin retailer cap screw with a grub screw on the rear so it clears the inside of the rim. For the front: you have to shim out the tires with a few washers. I did get a set of those 2.8's you were talking about, but they seem to be out of stock online a lot and my LHS doesn't carry them yet. They are the imexx rims/tires. These are what you are talking about...

Well, I didn't have to shave my back screw at all with my rpms and 2.2 wheels. But for my front wheels, i run stock because i like the low profile on the tires. I have the dished wheels from Traxxas that I would like to try here soon and am still looking at what tires to put on. I mostly bash with my jato(more like beat the hell out of it) so I don't race it. If I could just find a track around here! ARG!

You didn't have any clearance issues with RPM arms??

No, I did have issues using RPM rims, but not with the Agitator rims(i think this is what they are). I didn't have to shave anything or use a grub screw. I had the grub screws ready as I heard this before, but I still use the stockers back there.

Actually, I was talking about the RPM arms. :)

The RPM stuff is thicker and the rear inside rim would rub on the cap screw. Even with a grub screw, there is very little clearance between the axle hub and the rim...

I tried the B4 for an onroad basher with a Mamba Max 5700Kv and Lipo 3S. The motor placement does not work well. There is too much weight in the rear and it just wheelies at all speeds. I was getting 60+ mph out of mine but I could never just punch the throttle. I had to try and ease it up to top speed. Also the tower's get completely destroyed if you ever flip it over on concrete.

My next project, very similar to yours, will be something 4wd and have much more weight bias towards the front. I would recommend something like a 1/10th 4wd buggy with street tires. Maybe a Losi XXX.

Also the B4 with that much power will burn the tires up after 2 packs. Mine were completely bald after 2 runs in a parking lot.

Hope this helps since I just tried the same thing.

That's exactly why I didn't go with a traditional electric stadium-truck setup. Just about all the common ones have the motor in the rear. The only logical choice then was to convert a Nitro one. Even with some of the weight in front of the rear axles you still burn up the tires. But at least you don't have the wheelie problem.

It's a whole other world driving the Jato vs the Revo on a track. On the Revo, I have to tap the brake or at the very least not accelerate on the corners, otherwise I have too much understeer (yes I know an RD quickturn or center diff would cure this). When I corner with the Jato, I actually increase the throttle so I drift around the corner. When executed right, it works very well - now only if I could do it all the time. If not done right, I just spin out. It takes a lot more finesse IMO with 2WD.

I thought you were going on road. The off road principles are different. I am seriously thinking about a 1/8th buggy with street tires and brushless setup.

FD has a setup already for sale. 53.1 MPH on a 4S battery. Think what it would do on 5S. This is really catching my interest.

Yeah, I was going on-road, but I found it got a little old. There aren't any paved tracks that I know of around here and driving around by yourself isn't as fun as I thought it would be. It would be different if I had a 80+ mph vehicle, but the Jato aerodynamics are not meant for that level of speed.

After looking around a bit and asking some questions, I found there are pan cars that do have enough clearance to use in parking lots as long as the typical seams, cracks, and dirt aren't too bad.

No matter what, I like having the weight relatively centered in the truck.

That is an awesome set-up. Makes me want to build one too!

Post videos of it in action if you get the chance!

Thanks! The conversion was by far the easiest of the three I've done. Everything just came out right the first time around. Unfortunately, I don't have access to a means to record video.

A couple weekends back, there was a Nitro Jato around and it seemed to handle quite a bit better than mine. I think that is because there is more weight on the rear end on the Nitro version. So, I installed the battery box rear skid and put some large washers in it. Seems to handle better, but the only local track within 1/2 hour is muddy so I haven't tried it out there. Like I said, I layed it out for on-road use to avoid wheelies so it makes sense.

I'm thinking of re-doing the battery area and seeing if I can't fit 4s lipo in there. That calculates to ~80mph. Of course, it won't be that high, but it should beat any Nitro Jato around here. Hmm, maybe for motor lengevity, I might just use 3s. :dft003:

If You Get It Running Close To 80 I May Just Have To Drive Over And Play Cameraman For The Speed Runs!

OK! I'll keep that in mind. I just have to find a place big enough! Honestly, I highly doubt it will get anywhere close due to friction and wind resistance. Not to mention trying to keep it from lifting off the ground!

You'll have to create the first "aero" Jato body!

Maybe we could tweak a proline Dodge Intrepid Stockcar body (or brand of your choice) for the speed runs. Build in "aero-flaps" and use other aero tuning tricks. I'd be up for that! The fastest JATO!

OK! It'll have to wait until my buggy is finished though. Then, I also want to get the aluminum steering parts because there is too much slop IMO. Then, maybe the optional 7075 chassis. I'll also need to get new on-road tires and have them duct taped and perfectly balanced.

My poor 4600 won't last very long at that speed. It should definitely turn a few heads though!

We'll strap an icepack on the motor and duct air to the esc & motor if possible.

It would be a lot of for to see how fast we could push it!

Well, that was dumb. I got home from work and said "what the heck" and tried the Jato on 14 cells. Well, the first 50 feet or so was extremely fast and then the rear tires blew. Actually, the rim shattered which took the tire with it. Maybe it already had a hairline crack, I don't know. All I do know is that the potential speed was scary! Lesson learned here is that a perfectly balanced tire on very strong rims is a must.

I put some other spare tires I had laying around and ran it back on 2s and everything still works, so I'm OK there...

Hey BrianG, 14 cells don't hold a candle to a 3s. I have just run the T4 with it and a 5700, its insane

Well, the 4600 on ~17v is insane enough for me! It's making me think seriously about getting the proper tires, a 4s lipo pack, and then challenging just about any Jato out there. How the heck do you keep the tires from ballooning? I know the duct tape thing, but there's no way it could handle that kind of centrifugal force. I almost need a solid tire, or tires that have steel belts in them.

Foam tires?

That might work if I glue the whole thing to the rim. Is that how foam tires are supposed to work?

Any pictures of the carnage??????

No, no pictures, sorry. Not much to see really; the wheel and tire is torn up pretty good. Aside from that, not too much damage. Scratched up a brand new body, but that's OK. When the tire blew, the Jato did some crazy fishtail thing for a microsecond before flipping over and cartwheeling a couple times before landing on the wheels and spinning around several more times. It could have been a lot worse!

Did your teeth cringe? Mine do when that happens! But the jato seems pretty durable.

No, not really, it kinda happend so fast that it was over before I had a chance to cringe. I do know what you mean though - like when you take a jump that you just know is not going to turn out right...

Or a curb that jumps out atcha!:005:

Been there before! LOL!

I'm running a 14 tooth pinion on my T4 and you're calculator shows it running 52mph with 3s lipo and using 1/4" growth for tires (panther step pins). With an 18 tooth pinion it says 68 mph using the same parameters

No wonder why you love your lipo!!!!!!!!! Glad yo like them larry:027:

with the 14, its as fast as my Jato was before i detuned it

OK, I decided to re-do the Jato layout. Wednesday nights are electric-only at the local track, but there aren't any 1/8 buggies or MT yet, so I'm stuck using the Jato or the CRT.5 (if the plastic spur would be done, I could finish it!).

Anyway, I wanted to redesign it to use the same 5Ah lipo packs that my CRT.5 uses so I only need to bring one battery type, to keep the antenna inside the body, and to get more weight on those slippery back tires! Mission accomplished.

I ran the new version tonight a bit in my driveway and am quite pleased. Still have to work on that darn driver though. :)

So, onto the new pics. The new parts are nice and clean, but the rest is still dirty.

I still have the old parts and two 2s2p emoli packs (with about 30-40 runs on them) if anyone is interested. Old parts:
