A thread about Weight

[MRCking]

ENJOY: Let us know how it works out and post pics

I see it now thanks for the heads up MRCking. Now i can do this mod"thumbsup"

Like I said this was amazing for my MRC: But I think the average rock size around in TX estimated 8-10". So increasing the MRC reach was obvious.

Now with a 1/10 scale in TX reach is not going to be a problem.

I am thinking it would help you guys out in giant rock country. I know when I rock climb, if I stetch out my body reach and bring in my core toward the wall I can hang onto walls that normally would make me fall back.

Now the con: wheel base further apart would increase reach and stability but trade ground clearance. So again this would be great for large bolder type rocks.

Chime in.... I will stop babbling now... I am out of coffee. LOL

School is in session

Try taking a half inch off the fronts and adding it to the rear links. You'll still ne in spec, but shift your weight bias forward.

Excellent thought!!!"thumbsup"

This has been one of the more interesting threads that I have read !! I am on the hunt for shifting and reducing weight on my LCC as well !! Thanks for all the input !! I know it's already been said, but the Alum. tranny parts made a HUGE difference in felt power and wheel speed !! I highly recommend them !!

I got my LCC down to 1185g body on (no bat/wheels) could drop another 60g with a tekin esc but i like the mm pro in this rig

Ive saved weight in so many places even lathed my shocks (im running droop) to save weight.. i wasnt sure what to expect dropping so much weight from it but im glad i did, i picked up a win at Clovelly on the weekend and the bonus is faster acceleration/wheel speed + run time"thumbsup".. all details are in my build http://www.rccrawler.com/forum/showthread.php?t=244984

I changed out EVERY screw and nut on the chassis end to aluminum. I did not change out ANY of the screws on the axles.

Pre weight 1246g

Post weight 1223g

Total weight of screws and nuts (steel) on the chassis end 32g

 

[Hulksta]

You still got some way to go"thumbsup" mine is 1119g without wheels/body/battery;-)

Youre definatly one to chase!

I dont get why mine is more than yours???

Yours has MORE weight from:

Extra AL cross bars (2) approx 3g extra
(4) body mounts vs my (2) approx 7g extra
Bigger dig servo approx 15g extra
(2) plates on top of each set of upper links for mounts ???
Looks like a bigger/heavier radio RX ???
Fan still on the MMP 8g extra
More wiring ???
Lots more plastic on the transmission approx 2-3g extra
Your dig guide 1.5g extra
Aluminum axle link mounts at the axle and chassis ???

approx 37g more just what I have hard numbers for



Mine has MORE weight from:

No AL screws on the axle ???
Dig mount ???
Steering rod ???
Trans upgrades (on the way, hopefully) 26.8g extra
Shock weight (springs, turning down the body) springs weigh 13g, turned down body 4.4g
Aluminum axle C's (putting plastic ones back on soon) ???
Heavier drive shafts 12g extra

41.4g heavier for what I have the hard numbers for.


I just dont see where yours is 104g less than mine with the above listed. What do you think?

If you really want to drop the weight do your tranny shafts and outputs (i wouldnt bother with the alloy dig) and mate that ckrc steering arm is a pos:ror: i had one but have the RCbros high clearance knuckles with 8mm delrin link between the two and is sweet... i just weighed my old ckrc arm and 40g's im sure my delrin link is less:mrgreen:
Ive also lost the spacers between the shock arms & chassis and ive used alloy screws in more than the diffs;-) ive got the holding the servo/several in the chassis and about half the tranny screws are alloy too.. alloy nuts in everything BUT the motor mount & servo horn-link
I wouldnt bother changing back to plastic knuckles as the added weight is low & out to the corners where you want it but i would ditch the high steel steering arm"thumbsup"
I just weighted the 4x losi gold springs ive got here and they are 17g the springs i use in my droop setup is 2.2g:mrgreen:

personally i think if i remove more weight the performance will start to drop now as i noticed a few times at the last comp as i would steer out of a corner it would toss the rear :ror: im going to drop some weight from the wheels as i think this will fix it but im at the point now im starting to wounder if there is a target weight that if you under or over the losi doesnt perform as good?? on the other hand i think i think too much:lmao:

Dude are all four of your shock top shocks mount broken? Looks like all screws ripped out.

Also you qualify for dirtiest rig on RCC.

* If you cleaned it you might drop some serious weight, then you will be back in the lead.

:ror:

 

[scatterbrains]

Hmmm goin to have to see what my rig weighs w/o body and wheels, im sittin about 5.7lbs right now, lightened her up but needed to add 4oz back on the front, sedonas didnt want to climb. Prob work real good w/ rovers or boss claws.

Update: I'm sittin at 1257g w/o body and wheel asssemblies

 

[Erik D_lux]

Night crawler beadlock rings: 22g

Comp crawler beadlock rings: 38g

No picture but my rear wheel/tire/foam combo is 4.6g :shock:

 

[Erik D_lux]

Also did not take a picture but I upgraded my trans with every single AL part possible.

Stock trans with AL screws was 93g. Trans with AL screws and AL upgraded parts was 70g

 

[Hulksta]

My tranny with all the alloy upgrades is 84.2g but i used titanium screws in the centre of the tranny... looks like you lost a fair amount by taking the dremel to the case, personaly i would rather keep my case sealed:mrgreen:

I went with running single 4S 1,000mah lipos...they're tiny little things that pack a nice punch and great run times too...my rig feels lighter and more nimble.

How long of a run time are you getting?

What is the weight of one of those lipos?

 

[rooktakesqueen]

battery

They're very similar in size to the battery you sell but they're 1cm thinner. They come in at 110g. I'm running the MOA kit with 80t motors/12t pinion, and I get a solid 15 min out of them. Since I'm using the MOA kit, I just mount them right out front over the axle. I run 2 of them with a y harness for practice, and 1 for comps.

Could you post a link to wear they can be bought? I'm thanking of moving to 4s.
Thanks

I have been busy lately shaving weight on the LCC where it's not needed ! That and I siped and grooved my Rovers, Huge improvement overall. I still have alot of weight to shed to compete with Hulksta and his feather weight LCC. 1119 grams !!!...sheeesh !!

 

[C*H*U*D]

Great thread! I've been reading through it, and see your rear wheel weight posted....sorry if I missed it, but what's your front wheel weight now? Did you lighten them to the same as the rears after moving everything forward?

 

[djjiz]

I run a lighter setup and have shoegoo'ed a couple led squares to the outsides of the axles. They are Mr. Goodwrench lead and weight a little more then a standard tire shop uses and they have been hanging on for two years of severe temp changes.

This thread is killing me. I want a scale before Nats but maybe food will be a better choice right now.
