My First E-LST2 Conversion Project!

[jpoprock]

Hey guys! I'm almost done with my E-LST2 conversion finally! I decided to make it an LST2 rather than the XXL only because they don't make roll cages for the XXL just yet. That and because I know for fact that the New Era roll bar will work on the LST2 if you modify it. The RCSolutions Roll cage works too, but it requires some mods too. And if I were to go that route, I'd likely redo my battery box. The battery box and ESC tray were given to me (thanks Tim!), and he has some ideas for a new design. I do too. The ESC mount is fine as is though.

I have yet to pickup a front sway bar for this truck. I need a set for my Nitro XXL too. They make a big difference! I'm also going to pickup some RCRaven springs as well as a BAC steering link, ProLine BAJA body, New Era Roll bar, and maybe some shock covers too. I also need to clean up the wiring a little bit and may shrink all the leads in black, or use this protective covering that I got at Radio Shack.

I'm still waiting for my RCM pinions, so I have yet to drive the truck. I know I ordered a 23T pinion, as I plan on being geared at 63/23 which should put me in the mid 40mph range. I have some larger spurs to try too. I think the other pinion I ordered from Mike was either a 22 or a 24T pinion. I can't remember! I've got plenty of time to play around with it right now because it's winter time here and I'm not going to be driving it. Of course, I'll be able to check it out a little bit on a clear road, but I'm not going to bash with it. It can't get wet, and the Losi design has way too much access to the insides. But hopefully if it doesn't snow by Saturday, I'll be able to at least test drive it on road! I can't wait!!

I've still got to tweak my battery box a little. And you'll see that I'm using rubber as a battery spacer to keep it from moving around. The battery box idea was supposed to allow for the battery to be removable, but like Tim, I'm not going to take it out of the truck ever. At least not until a new box gets designed! I don't like the idea of charging it on the truck though, just incase something goes wrong and it explodes!

Here are the specs:
LST-2 Converted to Brushless
Neu 1515 2.5D/S
MMM V3
Marinepower EON28 4950mah 6S lipo
XXL diffs
XXL tranny gears
The Dude motor mount (modded by me to get closer)
The Dude Spindle
63/23 gearing (should get about 45mph)
Stock Losi shocks, hubs, and tires (20mm)
Losi 2.4ghz radio and rx

Items yet to purchase:
RC Raven springs
BAC steering link
New Era Roll Bar
Front sway bar
PL Baja Body
SR300 Rec so I can use it with my DX3S


Here are the pix!

Happy New Year guys!!

Interesting. I will suggest that you put some sort of hard plastic or al on the battery ends. Those fp packs do not have much protection on the ends and I would hate to see a stick puncture the pack. Other wise it looks good. I plan to make a new battery tray for my lst today, and maybe get it rolling again...

[doo540]

hey J

Your lst2E is looking good, a little to clean, get that thing dirty. haha
As far as protecting your lipo, just build a new top plate with sides that go all the way down to cover and protect the sides of the lipo.

As far as roll cages go, I think we all (meaning rcmonster family) needs to tell RC Solutions to build a cage to fit the new XXL and to gear it towards the brushless crowd. Its not like the nitro version goes fast enough to need a cage anyways right?

I have thought about buying the regular LST2 roll cage and cutting it apart and then tig weld in a section to make it long enough to fit the longer chassis of the XXL kit. We have at least 3.5 more months of snow here in michigan so that should be enough time to get it made.

I would lose the heatsinks too, I don't think you will need them at all. I have a smooth can 1515 2.5d on one of my lst2-e and it runs cool geared for 50mph.

BTW thats a sharp looking e-revo you have!!!!! I bet its fast.

Jason, It looks fantastic brother. That motor and battery combo should really shred !
But ya need to def do sumthin' about that battery tray gimmick on the end.

[junkman]

Great looking rig, you will love it, the e-lst probably get ran more than anything in my stable. I can measure if you want, a hyper9-e battery tray may work for you, and save you the time of fabbing up another one. Judging by where your box is touching the trans, and right behind the servos, looks pretty close to mine. I can measure if you want, might save you some time, and they are pretty cheap. This is the only pic I have of it right now.

[jpoprock]

Thanks guys! as I said in the photo comments, I plan to buying a new piece of alum for the top, cutting it to fit. Much like what Tim said, so that it folds down over the sides.

I'm not really going to be running the truck, since there is too much snow, so I have plenty of time to tweak it! This is just a really really good start!

I also stated in my photobucket pix descriptions that the motor heatsink I stuck on there only because I had it laying around. Not because I felt I needed it. It can't HURT, but it beats having it laying around in a box doing nothing!

I am having one small issue though. It seems like my motor is really tight. And if you roll the truck by hand, it's almost like the motor is fighting to spur gear. It's a bit "ratty" sounding when you roll it, or give it a hair throttle. It also looks like it's fighting the spur too. But once the truck gets going, it's fine. I'm wondering if that will taper off in time, or if the pinion will sorta break in to the spur? Both Pinion and spur are brand new. Tim told me his Neu is like that, but the exact Neu in my ERevo isn't like that. It turns smooth. This Neu turns in "sections" if you do it really slow. I believe those are the poles that I'm feeling? I can shoot some vid and upload it you want.

Tim/Bro... you guys can call me today on my cell if you want.

Happy New Year!

Thanks! A "real good friend" built it. He knew what he was doing because it's the best vehicle I've owned thus far!

wtf ???

[junkman]

I think you are fine on the racket its making. Mine is the same way, some motors are just "notchier" that others.

[jpoprock]

WTF does yer WTF mean? Ha! Someone told me if u rotate the motor shaft, u can tell how many poles the motor was. So, when you rotate my motor slowly, it feels like it turns in sections or clicks. And with a bit of resistance. My other Neu doesn't feel as "tight" as this one. And so if you lightly push the truck by hand, it moves in "clicks". The faster u go, the easier it spins. The slower u go, the harder it spins. I don't know how else to describe it.

I may know how to build a BL truck, and own several... But I have yet to learn EVERYTHING there is to know about motors, or the terms... Ha!

[jpoprock]

"Notchy"!! Yes, that is a great way to describe it. And tighter as well. It's almost like the slower you go, like say pushing it slowly by hand, that the spur almost wants to fight the pinion in the opposite direction.

Update: I had to run and get the fam some dinner, so I took the truck along for it's first test drive. I knew that where I was going there was a wide open parking lot that had no snow on it.

Let's just say the truck DID NOT DISSAPPOINT!!! Wow! It had a very nice throttle band that would really open up on the top end , was really torquey and low thru med speeds, and handled on rails. I was elated! It's going to be wicked fun to drive in the dirt and on big jumps. It's freezing cold out right now, so that meant a nice cool motor.

I can't wait for spring now!

[doo540]

hey J

There is no way you were driving tonight, I left Fort Wayne at 6:00 pm and it was a blizzard on the freeway!

I told you the lste was a blast!

BTW I have a XXL frame on order.

[jpoprock]

Hey guys! I wanted to give an update on the E-LST.

I need to order some aluminum so that I can fix that battery box, but the place I went to has a minimum order of $40 if yer not picking it up! They are way too far away for me to do that. So I might try McMaster, or Ebay.

I"ve done three test drives, and so far, i've been BLOWN AWAY all three times!!! I can't even begin to tell you how thrilled i am with this truck!! I haven't been able to shoot any video yet, and I have no idea how fast it can go (yet), but I'll let you know when I do. But the best thing about it, is that it's big, VERY fast, and extremely stable on road. I've not been able to take it off road because it's there is way too much snow on the ground, and the MMM can't get wet. So It'll be many more months before I can try it out on some dirt. But if It drives like it did with the Nitro, it's gonna rule.

I have a sway bar on the rear only right now. I don't know if I'll add one to the front or not. When I ran it the other night, the asphalt parking lot was a touch wet, but not enuff to kick up any moisture. Anyway, i couldn't believe how great it handled. My can/ESC didn't even get warm (However it was cold out). I ran it hard too. The coolest thing about it was that I was able to do power slides without applying the brakes!! The truck would drift around corners on the asphalt, while keeping all four wheels planted, and slide! It was crazy fun!!

So that's where I'm at right now. In LOVE!

But I wanted to show you what my gear mesh looked liked because I'm still bothered by how tight and "notchy" my motor seems. My mesh could stand to be a kiss closer, but it's still in the realm of "ok". I've had it closer before, and it made NO difference on the notchyness of the motor.



I also uploaded a video of what the truck sounds like when moving slowly. THIS is what concerns me, as my ERBE has the same motor and it doesn't do anything like this. I'm using a Mod .1 pinion w/ the Losi Spur 63/23T.

Check it out and let me know if it still seems "ok" to you guys.
