Who was wrenching today??? What did you do??

[Iowa_dude]

For these SXC24, springless is the way to go, if you want max crawl performance. 4 out of 5 of my SCX24s are running springless. The C10 is the only one still running springs.
Slimer is looking good, Man!

Thanks man. Going to play around with it some, try mounting the shocks on the frame. I know it can do better. Good news is, I ran him for hours and nothing fell apart! Definitely need a motor upgrade, still researching options. All charged and ready for tomorrow.

You can buy springs on ebay. I haven't looked into it yet for the SCX24's, but I have for other builds. You just need to know the length and diameter of the spring, then pick by wire diameter. It's hit and miss sometimes, so I usually grab the weakest ones and a couple sizes up from that.

Rock crawlers don't need to be sprung because they move so slow, so that is why having full droop is best.

Think about a regular car. You travel at higher speeds, and to get a soft ride, the spring needs to absorb bumps as well as potholes. So the spring is tailored to have just a slight droop, which allows the positive movement of the suspension over bumps, and some spring compression to force the tire down for the potholes.

Rock crawlers move so slow, and their tires are soft and plump, so they don't need this upwards movement to absorb the bumps. But having a little spring pressure to help push the tire down to get more traction in the dips helps.

Basically, to run a full droop setup like @Xraycer Is talking about, you want the vehicle to completely bottom out the shocks sitting flat. So you need a spring that is soft enough to allow that, or add weight to the chassis (sprung weight) to achieve it. The problem with these little trucks is finding a spring that will allow that, and keep the sprung weight as low as possible.

This is all just theory from studying suspension geometry and physics for other builds. I only have a few rock crawlers. But I watch a lot of rock racing and crawling vids for 1:1 vehicles, and have picked up a few things here and there.

Well, I broke it. Hoping super glue holds it together until I get new parts.
Question: should I put aluminum suspension arms or RPM heavy duty ones? Pros and cons? Any suggestions. Thanks.

 

[WickedFog]

RPM. I would highly advise against aluminum arms on anything bigger than 1/18 scale. And superglue won't hold that. It may for a minute, but you'd be better off with a plastic weld type glue, and even then it will likely fail again.

The only thing I wanted to today, get new suspension arms for the mini b, went all the way to Hobby Town and burned a whole 30 minute lunch break just to find out they was closed... then pulled a 11.5 hour day. Ill pick a set up on the way home tomorrow. And @WickedFog you were right, It worked for about 5 minutes until I bumped my trucks back tire.

Closed on Monday

Question. Where are you guys relocating your shocks to on your Deadbolts. From what I can see if I relocate to the frame it sits the truck even higher "cg". I can utilize the hole for the body mount poles but I would be bottoming out my front drive shaft. Just curious what yall are doing.
Also, when charging a battery "in pic" do I absolutely need to run a balancer ever charge or would it be fine just now and then to check each one? And to clarify if that's the case, I can charge up to 6 batteries of equal mah, so 3 430mah I can charge at 1.2amps right? Thanks

Yes, relocating the shocks to the frame will raise the ride height and the body, thus raising the center of gravity. Unless you run it without springs.
I have always just used the included charger. I believe they designed it to be a balance charger. Checking with my voltage meter, the cells are typically off by only +/-.01

After doing a bunch of experimenting, I think the original position works best for the shocks. I hate when that happens!

 

[Iowa_dude]

@Iowa crawler are you from Omaha area? My kids had wrestling and the other had orchestra both at the same time today. I didn't get to see either sadly, but i did manage to make it to Hobby Town for lunch to get my Losi suspension arms. they said they had the heavy duty RPM in stock, they did not. At least I didn't kill another lunch break. Ill go with OEM or until the next mishap. @WickedFog I have some two part epoxy "plastic weld" that I used, me and the kids went out and burned a pack with no issues. Thinking ill keep running until it breaks again then switch out.

Nice. You can reinforce the area with a layer of fiberglass tape under more epoxy.

I spent the day rearranging the hobby room... AGAIN. But finally got my corner shelf in to get the soldering station up off the bench. Still need to straighten up and reroute a few things, but it's getting there.

The Axial pit mat is badass. I love it.

@WickedFog I'm still jealous of your tool holders, and the custom front of your trays. Nice workspace.

I need to finish that tool stand. Just not sure what else to add to it yet.

 

[XeroMyHero]

I just got done putting my new OS .21 TM together for my Revo Crawler. Hopefully this weekend is nice. Weather is to be in the lower 70 degrees. I like to break in the motor and take it out to the trails on sunday.

 

[WickedFog]

Designed a holder for Losi shock oils to hang on the wire shelf above my bench. Printing it now, and will be done in about 20 hours, but it is going to be pretty sweet I hope

 

[Tunedfrog]

Your bench looks awesome Kev.

 

[WickedFog]

Your bench looks awesome Kev.

Thanks. It is a mess still. Slowly trying to find a home for everything. I need to add another shelf on the right side. I am running out of room.

 

[Doom!]

@WickedFog I don't think you fully understand the definition of mess!

Got this for a steal off eBay a couple weeks ago. Just finished the paint. New track beater for the summer.
