You can also buy spring assortment packs ($5) from big box stores like Harbor Freight and they have various size springs for even more tunability.

So.... the pen spring has to take up some travel of the shock right? The shock won't extend all the way, you'll lose whatever the length of the compressed pen spring is in extension travel.

Now you have four pens with "full droop" ha ha ha!

Initially stole daughter's nice pens... now useless. Had to rethink that strategy.

This is one of the Cooler Old School mods! 😎 MANY newer People never heard of this. It was one of the original Droop Mods. As you said, possibly the BEST of the options, because it leaves nearly all of the original extension. You DON'T loose that incredible articulation!! GAWD!!! I wish I could afford a Capra, and the right Tires. 😭 Carmine ✈🚂🚙

Yes great mod works well I put purple spring on front and Red in rear with 60 wt oil just great abilities...

@billderas3420

Yes. Agree that those springs and 60 wt oil work well.

When I built mine, I put the soft springs in the front but with 70/75 weight oil, and the stiff springs in the rear with 45 wt oil, I then also set my rear links for more anti squat, and the front for more squatting, and after breaking the truck/shocks in, I have no plans on currently of modding or swapping shocks like I orginally was going to do, just how I have mine set up

Hi Francis. I've watched many of your videos and taken on board some of your tips (relevant to me and the terrain I run on). Today I fitted this mod to my Capra, along with red springs in the rear and purple up front. Definite improvement over the same terrain before this mod! Thanks for your vids 👍

Absolute genius Francis!! who ever thought of this is on point! Never thought of modding shocks like that... Guess I'm going to the dollar discount store lol... Brilliant!!!

yes! and I would add, use a cutoff wheel to trim the "solid" ends of the pen springs down, it'll sit slightly taller for it, but same time when the spring inside does fully compress it's total length will be shorter too (for longer travel).

Great video. I always look to your channel for tips on all of my RCs, Funny I have not had any issues with the CG. I primarily rock crawl, so I need a little bit more height. Right now it’s bone stock. Planning to start my upgrades in a week or so.

I’ll say it again!!! Absolutely brilliant!!!!

I like your channel. I appreciate how you explain in detail.

I’m building my Capra now and I just happened to have 4 kyosho mini z springs laying around for my mini z buggies and they seem like they’re going to work great on the inside... I used team associated 60wt oil in back and 40wt up front...

@RCReviewChannel

You are hella dialed!

I was already running sightly heavier oil in the rear (20wt front, 25wt rear), plus the "soft" springs front & "med-soft" springs rear. I also have 2.75mm of limiters inside all 4 shocks...but, I've been considering the pen spring mod, instead of the limiters.

thx for the tip ill try this on my rig soon

You mentioned full travel with the helper spring, but doesn't the shock lose extended travel the distance of the compressed internal spring?

@RCReviewChannel

Correct. It varies with different springs' stack height at full compression. Ours lost 2mm of travel.

Is this a good mod for all crawlers? I recently purchased a TRX 4 Sport and wondered if this would be an improvement.

@GastonMaqueda

4 жыл бұрын

Same question here

My problem is the pen springs fully collapsed are 5mm... so it will limit travel nearly as much as a 90mm shock will or more. Going from a 90 to 110mm traxxas shock only increases travel by 10mm (25 vs 35). So that pen spring is eating up all the extra travel your shocks have. Why not an external negative spring? Something tunable? Maybe new spherical mounts that have the standoff for the shock to mount to the body on one side and the spring attachment on the other.

Francis is Mc gyver 3.0...😁

Wow tight thanks

How can you still get full travel? Doesn’t the pen spring take up some room when it’s fully compressed(shock pulled)?

@Squintz45

4 жыл бұрын

Yep, depending on the compressed height of the spring. Probably removing 5mm or more from the fully extended length.

That's a great idea this should work in my vaterra it has bad torque twist😎😀🍻🤘🏻✌🏻

@RCReviewChannel

4 жыл бұрын

Exactly!!!!! We tried soft springs and torque twist was awful. Also try heavier shock oil

How can it still have the same travel, doesn't the pen spring prevent the shock shaft from extending fully?

@rowntrp

Worden B, I also wonder about that, I would have thought with pen spring mod that you would still get full compression, but extension will be limited by the height of the compressed pen spring inside the shock.

@7philly5

He’s right you only loose a couple mm and it isn’t really noticeable but it is lost... also depends how soft the internal springs are... I used kyosho mini z buggy springs...

@wordenb1830

You would lose the length of the compressed spring, in the pens I have looked at this is at least 5mm. I can however see the advantage of the pen spring over a shorter shock absorber in that you lose nothing on compression of the shock.

I need to test this out

Can you please give me a link to the wheels you have on your capra , thanks in advance. Love your channel btw, very informative.

I dont have a Capra but could you not just run a droop setup?

so after the pen mod what weight oil in the front and what weight oil in the rear? not sure if i missed it in the video?
