The Capt's Brushless Lst
 

I finally got my LST converted using the FINE DESIGN conversion. It was pretty easy (A little expensive but I thought it was worth it and so did the MISSUS no more noise in the yard LOL)) and the system mounted right up (with a little dremeling). I was always good at nitro but I'm really leaning towards brushless now. This thing is Just as powerful if not more than with my Surefire Racersedge 32 or Lrp 28 Spec 3. And the convenience is just undeniable. Here are some pics of the setup. And a short video. It is a little boring just some high speed runs and some light bashing in my yard. The crash at the end is worth it. Nothing broke LOL. I like the way the power system lifts the front wheels up when it shifts into second like a shot of NOS.:027:

Nemises motor
WARRIOR 9920
4s2p 3700 LIPO

Please let me know of some better setups for down the road as I have been into nitro for the last 3yrs and could use the help. Thanks Mike for all your help also in helping me convert My buddies Savage.

Hey man, sweet LST! Looks very clean and well done!

Nice LST.

I would not twist that controller wires like that. Shorten them, or route them different.

what wind of motor is that?

You sure it is a 4S2P pack, and not a 4S pack? Looks too small to be a 7400 pack.

It's a 3700 pack. Look at the label.

I've seen that..

but this was what was confusing me;
4s2p 3700 LIPO

It looks like a 2s2p to me, mine is that size 8000mah, well approximately anyways, can't tell from the pics that well.

very nice lst man.....very nice indeed

I don't think so......

It has got 4 balancer leads and a monstertruck doesn't run on 2S that well...

I went by size not the taps.....out to get me again!

Sorry for the bad Info. You can tell I am new at this. I just looked it up 4s pack 3700mah.

Firefox Lipoly
4S - 7.4
3700 mah
20c rated

The New Fine Design is 18 oz lighter then 12 cells nimh pack with twice the Punch.

E Maxx Guys, 1 14.8Volt/4S pack is Fine, But If Balance. is needed yuo could buy 2 4S packs and wire them in parallel for 7400mah!!!!! and 150 amps continuous amp draw! Or you could buy 2 2S packs and run them in series at 3700mah BUT loose over 1/2 the weight of a Nimh setup!

* 14.8volts
* 3700 mah
* 75 amp Continuous drain That Double what a Nimi pack can give up.
* Weight is 14oz.
* 6''long 1-3/4'' wide 1-1/8'' Tall.

Fine Design also offers the NEW Lipo cells fully factory water sealed for an additional $4.00

In any case. it's nice! LOL, it's ok, my info is always off! (apparently) :)

Yes, and that's exactly my goal. To get you sharp and post-accurate.

Not advertising for fine-design, right? LOL

maxamps packs are 4000mah, cheaper, deliver the same power (about 35 percent cheaper than the cf packs!!) and available from our very own Mike!

A 4S 2P pack would be my choice for such a heavy truck. What low votlage cut-off are you using?

Nice conversion!

Quick question: Is that the stock Nitro clutchbell on the motor? If so, what kind of a adaptor did you use to hook it to the motor?

Welcome to the forum Captainbolic.
I like the lst. I been debating on geting me one.
It is nice to see you bashing it some.

Yeah, was it something that was pressed onto the clutch-bell or did it come seperated from it?

I was also curious about that bell. didn't want to ask though, i was also curious how the metal on metal is going to wear?
Serum: it's allllll good! Still got love for ya! LOL

I'm sure they are using hardened steel, like what Mike uses on his pinions for use with steel spurs.

I believe the whole thing, including the stock clutch bell is put together by the people at FDM.
Looks quite neat, but I doubt you'll be able to change pinions that easy. Plus, these clutch bells are very heavy.

Yes, the weight, being so close to the fastest turning part of the car is a concern. 1oz extra on that motor is like 17oz at the wheels with a 17 to 1 ratio. (not saying it is 1 oz)

i guess it's the same concept as brass on aluminum then. I think it's a neat idea. But yeah, the weight? Hmmm, lst's aren't all that heavy are they? I would think almost weight would more of an issue like in a maxx or something?

I see what you mean by weight now...sory, posted the same time!

read my post neweuser, and you know why weight so close to the motor is a bad thing.

right, i just did after i posted..LOL, basically saying spinning something heavy is not a good thing?

You might want to put some foam under the ESC.

nice lst man.

brianG, a guy that i know has a FD lst and he said that the "pinion part" is JB welded into the clutch bell. i was suprised to hear that actually.............

Knowing Fine Design, I'm not...

Wow. It looked like a mod, but I didn't think it would be so crude. I suppose if it works...

The line between 'working' and a 'good solution' is rather thin.

It's not something you want to depend your number 1 position in a race onto.

Funny Fine.
Abolic, if you need to modify the LST go to Mike, you'll never regret it. Trust me.

Maybe Chris Fine Drilled out hte center of the clutch bell or something.... I wans thinking of making an adpater for a clutchbell... that would be awesome.. and not too hard if you had the tools... But Very nice LST.... You got everything as a whole package from FineDesign?...

yeah, except for the charger.

The clutchbell has a Mod one pinion expoxied into the the standard LST2 clutchbell. It must be a 25 or 26 tooth pinion. I was hoping for a custom one peice design. But It works and has stood up to a ton of abuse so far. FD made me stock LST1 clutchbell. We have a guy over at http://lstforums.com that makes hardened pinions in anywhere from +2 sets all the way to +6 sets so I can vary the speed and performance.

Thanks for the foam Idea under the ESC

AQUT,
Yes I got the whole package from them.

Serum thanks for the advice on the MAXAMPS PACKS I think I'm gonna try tis one
MaxAmps Lipoly 4000mah 5S 18.5V Pack
# 4000mah Capacity
# 18.5 Volts
# 44mm X 137mm X 32mm
# Rated at 60 Amp Constant Discharge
# Rated at 80 Amp Burst for 10 seconds
# 455 grams
# Comes with Standard Taps

that sounds like it would work, but i would worry unless it was pressed in.....but who am i to say what will work & what wont.....heck if its working then good....

Why does the brushless LST have to use the receiver pack? Other Brushless setups don't need the receiver pack.

It depends on the system. Most run ubec. It has nothing to do with truck.

I'd love to see a picture of the inside of that clutch bell. I have been trying to fgure out a good way to convert one to a 5mm motor shaft mount. I thought about JB Welding in an adptor, but never seriuosly thought that it would be strong enough to hold up. I would really apreciate it if you could take a picture of the adaptor epoxied inside and post it for me.:dft009:

Jhautz,
I'm at work now but I will get a nice detailed pic of the clutchbell tonight when I get home.

Cool,
I am running four servos. On a 3700mah pack I'm getting about 18min run time befor it wont shift into second. With a UBEC how much run time do you think I will lose using the UBEC over a seperate receiver pack?

Thanks for the help.

The CAPT

You probably won't notice the difference in run time. It don't take a lot. If the
servo uses 1 amp and you have 12volts in 6volts out. It will only draw .5 amp from battery. Just for example.

very true, when i switched from a receiver pack , to a ubec, i didn't notice much of a runtime difference, but I did like the fact of how the servo's become more responsive...

That would be great. Thanks!!!

That is a sweet looking truck BTW

The biggest thing I like about the UBEC vs reciever pack is that the servos never slow down from the reciever pack getiing low.
