Losi LST E-Conversion Kit - Page 3 - RC-Monster Forums

42mm motors makes this far more viable (assuming you can do something with the batteries). Plus, no tape shims!

To my knowledge, the LST has never had a CD option. The parts they have you replace are (from what I read) a slight gearing tweak to work better with BL power. I'm not sure if there's enough room in the trans case to even mount a standard 1/8 size diff.

That sounds a little better for this kit.

Looks like you could mount the battery tray/esc mount on the front if you ditched the radio box. You would not be able to use the blue support post for the esc tray, so something would have to be fabbed up.

Seeing that a tdr mount is 70 bucks, and the 1 speed hub is 40 bucks this is cheaper, but I am not sure how much gearing adjustment it will offer for those of us who use a 1 speed hub and set screw pinions. Looks like this retains the 25t/63 gearing. If it is designed to use all of the losi supplied gears you may be able to get a 25/59 to fit and mesh correctly, but that is losi's smallest 2nd gear spur.

The motor mount is interesting, and quite low cg. Putting the battery over it is a step backwards, but if you retain the mech brakes and mech reverse there is really not much room in the front. I can see this being a great conversion for 4s usage, due to the 2speed and mech brakes. Or a hv setup that uses a feigao motor. 14xl on 8s lipo with a 60amp hv esc would be great. Use some 2500ah lipos to keep the weight down. Still going to wheelie alot.

My buddy has a Raminator that is in great shape, nitro, and runs like beast. But the market is so bad that he didn't even get $80 for it on Ebay. So he kept it. I told him he should E-Convert that bad boy, but the cost of a MMM/NEU, and the TDR Parts makes it an expensive endeavor. Not to mention it would be better suited to get converted to an LST2 as well.

Looks the verdict on this Losi E-Kit is a...

thumbs down!

I wasn't a fan when I first saw it either, as evidenced by my post on page two. But it is a kit you can work with. I got a really good deal on a Aftershock with the Losi kit with Losi single speed and MMM2200 combo. Driving it is like driving a cc2650kv powered rustler on 4s, yea it's that bad. But it's not hard to cut the upper deck off the battery tray (leave the upper slots for the straps) and mount it up front. Switching to a erevo rx box saves some space and a piece of plexi with a TRX MMM mount takes care of the esc out back. Truck drives like it should now, still wheelies but alot more controllable. Gearing is prettt much limited to 25/63, can't go smaller on the pinion or spur. But this works well with my current 1520 1600kv on 5s combo.

I don't know if you necessarily need the full LST2 conversion. I do know with the 1515 every run I was either spinning the 14mm hex in the rim or spinning the pin inside the hex! I had another MMM and the 1520 so the 2200 combo was sold to fund the LST2 conversion. Can't complain as I have about $75 into the roller at this point. When I eventually make it into an XXL with center diff, I'll assemble all the leftovers (basically an aftershock) and see how it holds up, with 17mm hexes and rims this time though.

Hey Overdriven- want some fun news on LST center diff conversions? Ofna Ultra series center diffs are a direct replacement for the tranny. and you know how the driveshafts just barely sit in the cups on the LST tranny? An Ultra center diff is a hair wider than an LST tranny, so the driveshafts fit in the cups even better than a stock tranny. Use an ultra dm-1 spool if you want, or a center diff. I have a spool in my LST conversion. I'll get updated photos in a day or two. You'll see them here in the brushless section.

I seem to remember reading that, I believe in your LST thread. Thanks for the heads up though, look forward to seeing more of your build. Not sure what diff to go with, I have an RC-M losi mount but no diff, and I might go bigger than XXL to 1/6 like brian015's latest build. Gotta see what I can fit in between the rails (inspired by Bondo's build) and do some gear calcs too.

How are the Losi holding up?
I haven't seen many talk about breakage.

Robl45 · 12.23.2012, 02:37 AM

couple questions here, hopefully someone can answer. I converted my lst2 to brushless probably 4 years ago. used the fine design mount and an xl11 motor I think it was and a used FD battery tray that i picked up. its worked fine for me but the I got a forward only esc and have no place to really mount it, rigged it so it works the way it is but not really happy with it.

this kit looked nice because the battery box has the esc mount on it which would help.

So anyway, can someone explain why you have to change gears in the transmission? I never did and the truck has run fine for me and its on 6s as I had the batteries laying around. way too damn fast to be fun though with the current setup.

Also, if I wanted to ditch the mechanical brakes and mechanical reversing, I would need to do the forward only conversion, is that correct? I'd also have to ditch the 2 speed and just go one speed with a dude racing hub?

Overdriven · 12.26.2012, 04:22 PM

There's no need to change the gearing inside the transmission when going brushless. I'm guessing you've seen the Losi Conversion kit has different bevel gears and seen some people switch to XXL spec bevel gears. Both the XXL and Losi E-kit gears will make the truck faster. If you're happy with how it is there's no reason to change.

If you want to ditch the mechanical brakes you have to ditch the 2 speed and convert to single speed. With the 2 speed you cannot use esc/motor braking and have to run mechanical brakes due to the one way bearings. The Dude makes a nice single speed hub, the Losi is cheaper. You'll also need a car esc with braking.

To ditch the mechanical reversing you have to do the forward only conversion. The only one availible is from Losi. Or if you're cheap you can use some JB weld on the gears inside to hold them in forward like I did on my nephews LST. Works just fine, but the extra gears are still in there addidng weight, unfortunately just didn't have the cash for his truck.

okay, so mechanical reversing I can get rid of with the forward only conversion. Then I can stick 2 speed and use the mechanical brakes or do the one speed hub. I didn't know losi has a one speed hub??

truck is plenty plenty fast right now. even with the wheely bar, I managed to flip it on its back the other day and watch it slide down the street. ate right through the back lip of my beautiful almost new body. Yea, a couple of tears were shed.

So is it better to keep the mechanical brakes? what are the pros and cons?

Robl45 · 12.26.2012, 09:08 PM

one other question, what size motors will the lst electric conversion fit? With the mounts I have now from fine design, I can fit 36mm motor and if mine every goes, it seems 36 mm motors are in short supply so will the losi electric fit the 36 mm and other sizes?

Overdriven · 12:52 AM

Mechanical brakes take some load off the esc and motor resulting in lower temps on both. Mechanical brakes also allows the use of esc's that don't have brakes like air and boat esc's. Some people also like the feel of mechanical brakes too.

How are the temps of your motor? An 11xl is not the most efficient motor out there and ditching the 2 speed and mechanical brakes will make it work harder raising temps. Ditching the 2 speed will make it easier to control wheelies though.

Edit: If you read the through this thread you will see the Losi kit fits up to 42mm motors. I found the Losi mount held heat in the motor since a 42mm motor won't contact the mount along the can so it can't act as a heatsink. Read through my other post regarding layout and gearing limitations.

I just wanted to confirm that it would also fit a motor as small as 36mm.

Here are a few pics of mine.

I managed a very simple cheap conversion. Then I bought the Losi Single Speed Conversion, which needs longer bolts to hold the gear & put nuts on the exposed threaded end. I had mine fall off. With nuts, no problem!

Now running a 34T pinion. This motor is the 1717 1580kv Castle motor, Castle Mamba Monster on 6S. The closest thing to it now is the XO-1 motor.

Also, I changed to motor brakes because I could not get it to stop or stop chewing through brake pads & discs. They would glow red in the night time!!
