E-LST Conversion

[looseman]

Your list looks good to me.

I was not happy with the ESC's internal BEC it only puts out 5 volts. Either run a reciever pack or get a castle BEC for better turning power.

[f22warzone]

I am willing to bet your ESC is messed up like my new refurbished one (green circuit board) my old blue board puts out 6v and a lot of amps to drive both my servos (760 oz of torque) but the new one only puts out like 5v under load and then has brown outs if I turn to sharp.... going to send it back whenever they get back to me.

[Aussie_Dutch]

So in other words I would be safer to be throwing in a seperate BEC now... I was going to do that when I do the single steering servo conversion... The truck will be safe with this setup for the moment yeah?? I don't want to spend all this cash to break it first time out, I can handle if something breaks cause it has had no attention as yet (e.g. Diffs, chassis, steering), but the BEC in the ESC should be fine for the moment, shouldn't it??

Also, there is so many different charging systems for lipos out there, what systems do you guys run.. I need something that can balance the batteries... Being that I have to buy a new charger, I may as well get something that can balance as well as charge and discharge

Also, been trolling the site where I am planning on getting the motor & ESC from, I have found this accessory for the motor... Would using this be able to influence the decsion on what battery to use? The site claims it can assist in keeping the motor 30°(I'm guessing F rather then C being it is a US site)....



Also thinking of getting the ESC mount kit, just to try and keep things looking half as clean as what looseman's conversions are...

[looseman]

No, you don't need the BEC if your runnin stock servos. I run the boys truck like that.

Bondo is runnin cheap Hobby King Balance chargers, the same place your gettin your batt from, and he likes em. One of these days I'm gonna get one too. I'm stil rockin a Blinky Balancer.

The Traxxas ESC mount rocks and it's a cheap insurance policy at only 3 bucks.

Your image didn't come thru, what is it, a heat sink or something like that?

And to Warzone, The MMM is only rated for 5v. With the Castle BEC I'm rockin 7.4v, Major yankin power.

[f22warzone]

I have this charger
http://www.hobbyking.com/hobbyking/stor ... er/Charger

its the exact same as this one

http://www.hobbyking.com/hobbyking/stor ... er/Charger

except that was out of stock when i wanted to buy one

this is the one i want
http://www.hobbyking.com/hobbyking/stor ... ce/Charger
man would it be nice to charge my 5x 5.8Ah and 5x 5.5Ah batteries at 1c at the same time : )
(parallel charging)

recommend you get the new nano tech batteries as they have higher peak discharges and are suppose to last longer(more cell cycles) , but if you don't want to be on the edge of technology pick you up http://www.hobbyking.com/hobbyking/stor ... oduct=9518
some of thos.

and how the heck is it only rated for 5v when mine is putting out 6v : ) .... well anyway 6v is plenty for me ( tested with multi meter under servo load : )

No, Bondo has a Venom Pro Charger/balancer, A Multiplex charger/balancer AND a HYPERION EOSO615i DUO3 Charger/balancer

The Traxxas ESC mount rocks and it's a cheap insurance policy at only 3 bucks.

Dam Fine idea

Major yankin power.

You talkin about pulling your pud again ?

[Aussie_Dutch]

The image is of a little fan and shroud that attaches to the motor with some zip ties... http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXYVB4&P=M

Okay... Nano tech batteries... What sort of charger would I need for this?

Also, I need to sort out what battery I am going to get.. Would it be better off getting a nano tech battery now? I like the sound of longer run times... Also, still very confused regarding which type of battery to use. There have been recomendations for a 4s, now another is saying get a 6s, and the same guy talking about nano tech batteries... I am so lost in all this...

If you ultimately decide on 6s, which is nuts ? You'll need a different motor with a lower KV. Nobodyy mentioned that tho huh ? Careful whom you listen to.
If your new to Electric stick with 4s, it'll have nearly twice power than the nitro motor ever did.
Most guys that run 6s think more power is better but they break parts far more frequently and some can't drive worth a shizz anyway let alone with all that needless power ?

Anything higher than 4s you WILL break more parts and the wear and tear on the whole truck will compound twice fold.

[Aussie_Dutch]

Okay, so we stick with the 4s...

What can you tell me about the nano tech batteries? Is this even something I should consider at this stage? Looking at:

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11957&Product_Name=Turnigy_nano-tech_5000mah_4S_45~90C_Lipo_Pack

Your advice? Do these batteries run off a standard Lipo charger with a balancer? I don't want to get a battery where the charger will cost me a further $1 gazillion dollars...

[looseman]

If you have run a 4cell with the 2200kv you will not need a cooling fan, temps will be minimal.

[BrushlessBondoNutz]

NanoTech's, They are still reg Lipos just a much higher C-rateing which is a big PLUS !
Great choice of pack, I plan on buying some myself when my finances get back up(spent a ton on a 1/6 scale build)
Get what ever charger/balancer you can afford as long as it will charge with a minimum of 5amps, watch out for weither they are AC/DC depending on what you need.

[Aussie_Dutch]

I have looked into this, and from what I can see, works out roughly $20 more for me to go with a nano tech battery and a different tray...

Looseman, how much room do you have between the battery tray and shell? Would there be room to run a battery in a tray roughly 169mm X 51.5mm?

Aussie dollar got a little stronger yesterday... Made the whole conversion a little cheaper...

[looseman]

Plenty of room in a stock LST2 body. It's designed to go over a pipe on one side and the output shaft on the other. Ive got another 3/4 inch on either side easy. I don't do mm.

[Aussie_Dutch]

With the movement of the Aussie dollar, and me making the decision to get all my parts from shops in the states, I have a few dollars still there for parts... Now time to continue making this beast work...

I don't have enough cash to do diffs just yet, I feel these will be what goes pop first, and I will deal with them when the first one goes bang. But I was thinking that due to FOC I will have the tranny out, and opened... Would it be wise maybe to get a set of XXL output gears and get them going in there? How would this affect the cars overall speed... And I am also thinking that I will do the gear swap in the tranny too...

Bondo, can you work your speed calculations on this...

[Aussie_Dutch]

After much reading of the data in the library, I am thinking that I should maybe be buying new bearings and shims just to have in my pitbox... Which ones should I be looking at purchasing that could be required during the conversion... I would be thinking more tranny related bearings and shims... Cheers...

Also been thinking that if I am to have the tranny out to do the FOC and gear swap mods, I would prefer that this be the only time I have the tranny out.. What other things should I do to the tranny? HD Outdrive cups (Do these go on the diff or tranny side? I have been looking at my truck and they seem to look the same on either end...). Also, I have been seeing some posts about "gorilla snaut".. Is this the best stuff for lubing my tranny and diff's with? Or should I just use a std grease and diff oil?

[Aussie_Dutch]

Anyone? I want to do some of the purchasing today...

[BrushlessBondoNutz]

You can't go wrong w/the Gorilla Snauwt, great stuff for sure.
Looseman uses it when he pumps the neighbors dog.

Dont worry about bearings or out drive cups, the stockers are plenty strong and will last a long time.

Go on Ebay and buy a couple complete XXL diffs from JennysRC and check them and shim to perfection. Use as spares, just change the complete diff and worry about repairs later.

[Aussie_Dutch]

Well, I been shopping this morning, now the waiting game for UPS and AustPost to do their thing...

Waiting on...

Spur Gear, High Speed (63T)
Forwards Only Conversion
Engine Support Brace: Aluminum Blue: LST/LST 2

Traxxas Mamba Monster ESC Mounting Plate
Turnigy Nano-Tech 5000mAh 4S 45~90C Lipo Pack
Turnigy Accucel-8 150W 7A Balancer/Charger

I am yet to order the mount and single speed from TD Racing, but as soon as my paypal account is active, I will do that...

[Aussie_Dutch]

So still waiting for parts... But in this time, I have been reading heaps, and deciding on what is next for the beast...

And so far, looks like I will be building a new chassis setup based on what mistercrash has built. I find the setup on this truck very balanced, and will also allow me to persue part of my life that I enjoy... Fabricating. I have a little experience with making stuff, but all the stuff I have made previously has been more relating to automotive parts... So I hope the few skills I have making stuff can help me make the required parts. I will admit, I will be cheating to a degree, and getting all the metal parts cut by either CNC or laser cut. I have mates who work in the right parts of the metal industry that can help me, now I have designs to work from. So now the challenge is to get the other parts needed to make this chassis work...

I will keep everyone in the loop... Once I have all my parts for the e-conversion, I will build it with the current setup, as I don't think I could look at my truck much longer without driving it... hell, been nearly 3 months since I have had a good bash with it, and I am itching to drive it again... SO with the build of the new chassis, I will get it to a stage where I can just transfer all the required parts from one truck to the other, without having any down time...

Let's see how this progresses over the next 6 months... I will be making a list (and checking it twice) of the parts I believe I will need, and post it here, if anyone has any parts to assist, or can recommend better parts to use, feel free...

Lets get ready to rumble... (silently as it is brushess....)

[BrushlessBondoNutz]

Here, put this on your list.

[Aussie_Dutch]

thats twice in one thread that race motor has come up.... This is not a racer, I shall let you enjoy that one all by yourself...

[BrushlessBondoNutz]

Uh, OK ?

[Aussie_Dutch]

What motor is that?

[BrushlessBondoNutz]

What motor is that?

You want one, there are special order only for the deepest of pockets and other regions.

[Aussie_Dutch]

Nah, not the nued motor... The one that is the size of a coke can.... That is massive... what is a motor like that designed for? RC helicopters, one of the really big ones?

[Aussie_Dutch]

Can anyone tell me if the VW Beetle Baja body will fit on an XXL? Don't want to buy it and not have it fit....

[jailbird]

I think it'll fit but it's pretty short. Body length is 19.3" with a 12.5" wheelbase.

Lucky you worded this like you did ^^^, you would have fallen into a trap. Smartman.

For RC Boat/Heli applications. Ment to run on 12s and higher. It's about a $500.00 motor, not for the faint of heart or checkbook.

[NeoBart]

Damn man I didn't see that coming, I would've walked right into that.

[Aussie_Dutch]

Okay, real noob question...

I keep seeing posts about slipper clutches... Do I need to purcahse one? Or is there one already on my truck?

I know with the future conversion I need one, just have no idea if I need it to hook the first stage of my conversion up...

Cheers
