THE Weight Management Thread by RedMan3

[RedMan3]

Hey guys, I was out yesterday with the girl (2+ hours at a hair salon makes me wander around a shopping center) and walked into a Goodwill. Thinking that i would find something, a "Diamond in the rough" so to speak, i luckily found a useful r/c tool. It is a chefmate scale that measures from 0-2kg. Bought it for $4. SCORE.



Well I am starting this thread so that you guys that are either racing, or going for 70mph will have something for your benefit from me. I will mass most any part versus another so that you can manage your weight of your jato.

Like say RPM arms vs the stock Trx arms. OR different tire/wheel combos to lessen rotational mass.

Here is an example:




Rear tire data:
Jaco Foams- 88g
Road Rages- 95g
Anacondas-101g
Alias- 106g
Talon- 152g

NOTE: All tires are with "fresh" tread.

Make any requests, and ill see what i can do.

pullstarter vs EZ...

wheelie bar vs the rear attachment when u take off the wheelie bar...

[Desert JATO]

thanks redman 4 offering this kind of help
stock drive shaft vs. any CVD
's
TRX3.3 vs any possible o.s engine : .18 or .21 ( which is available )
thanks again

[forbes]

right on my new best friend lol!!!!
a shock with 30w oil verses 50 w in stock form!!!!

[RedMan3]

Pull start- 25g
EZstart (w/ wire harness)- 136g
Rotostart- 35g

NOTE: Recorded without one way bearings inserted.

Ill do next (later this evening, i have a drag race today):
- 3.3 vs OS18tm vs .21 (Thunder tiger engine from scumacher fusion) vs .26 picco max
- CVDs vs stock driveshafts
- Rear bumper vs Battery box
- AA battery holder (with batteries) vs Flat pack
- RPM arms vs stock arms
- mass of anti roll bars
- mass of roll bar (handle)
- mass of side mud guards

Any more requests

......

Any more requests

efforts appreciated good luck in the race

[RedMan3]

i only have 30wt (stock oil) and 40wt losi oil... but ill do that.

I can also do Stock shock vs Teflon hard anodized shock body shock.

And:
- stock 24t clutch bell vs 20t robinson racing revo cb vs 17t revo cb

[jato_revo08]

good man, i might go 2 good will and see if i can get anythin i can use ha ha. good thread red

[revonitro]

Finally, a very useful thread. The forum gives so much to most of us. I'm sure it feels really nice to give something back.

Great job RedMan!!!

no joke...... thanx for ur contribution red...... hope we don't wera u out

[js4544x4]

what about servos and i know some normal AA batts have a big weight diff.

[Break_u_off]

What about the stock 6061-T6 aluminum chassis vs the Titanium-Anodized 7075-T6 aluminum chassis (which is suppose to be 10% lighter then the stock chassis).

[jato_revo08]

+1 on that

[Jato25n33]

I have one of these scales as well. It was a great buy, even though I paid close to $30.

If anyone needs parts to be weighed that maybe RedMan doesnt have, I can weigh them.

[mikesr]

How about 4 double a's vs. Traxxas 6v Battery.

[Jato25n33]

How about 4 double a's vs. Traxxas 6v Battery.

4 AA in the holder = 105g
My Venom 6 volt = 102g

I am going to put RPM arms on my Jato now. I will weigh them also. I know RPM's weigh more, just note sure by how much.

Here's a few more things for you guys:

-2.2" mounted foam tires = 63g each
-1/8 scale Ofna mounted foam tires = 70g each

-Stock arms: front = 14g each, rear = 19g each
-RPM arms: front = 19g each, rear = 21g each

[Switch_639]

looks like your gona have your work cut out RedMan...

[HiFiRobbie]

RedMan, this really is an awesome thing you have offered to do.

Even though I don't race and am not really interested in the "weight game", I feel I should say thanks just for being such a great contributor to the cause.

I really hope the rest of the forum shows you the appreciation you deserve. Although I see that quite a few already have!

Thanks again!!

Rob.

[Over_revO]

Yep, good idea there

Since weight is everything when you want the best acceleration out of your truck .

Thx for sharing!

Better appreciate this...




Ill try and do the chassis' by going to my hobby shop and massing them there.

Questions/Concerns? Requests?

[Switch_639]

thats like your whole car takin apart... are you bored? no, just kidding... this will surely help us all with weight shedding...

[Jato25n33]

RedMan....I weighed RPM and stock arms yesterday and your weights are different then mine.

[RedMan3]

Our stock arms are the same dude. My rpm arms, amazingly both came to 20g. I can take a picture of them on the scale if you really want me to prove it. But im assembling my car back together.

here:


Honestly though... you have to consider that not all of the arms are the same.

[Desert JATO]

really tremendous work Redman thanks for all this huge info
i’m sure it’s gona be helpful to many a round.
You just confirmed my guess about certain subjects weights.

[js4544x4]

yea thanks for taking the time to do all that. it will be used on here for a long time.

when you get it back together would you be so kind as to weigh the whole car with fuel and list the parts on your jato . that would be VERY VERY helpful. this way we have some idea of total mass. thanks for strippin your car down buy the way.

[Jato25n33]

I have weighed my Jato before. Since then, I've added new parts. I will weigh it later today.

[Jato25n33]

I added another few parts today and then I weighed my Jato. I did not have fuel, tires or a body on.

It weighed in at 3lbs 8.8oz like that.

With tires on it is a little over 4lbs.

[deepsouth]

and the jato stock ways?

[forbes]

thanx red.... i believe u just help me on something.... hats off for ur factual informative post.....
u r one of the few... who post actual facts on data needed by some of of s and just not ur opinion (which i have been guilty of myself)

thank u

[Jato25n33]

Weight (no fuel) = 83.03oz (5.19lb) (w/4AA in rear + wheelie bar)

[trxracer1]

thank you red and jato
