Very clear improvement. Thanks for showing that. I get tempted to get my Losi Comp Crawler working again. I remember it being capable when it wasn't just a roller. With some current electronics I think it would be fun.
Amazing job Fran what a beast your turning into 👍🏻💯 that lightweight revolver probably made as big of difference as the brass but working together really made a huge difference
Yes, the Revolver lowered the CG since 130 grams of high weight was lost compared to the previous Holmes Puller Pro. However, the vehicle lost some forward weight too so the steepest climbs were difficult. The Brass portal covers gave it that forward balance again and at a much lower point.
Thanks for sharing, very useful and practical comparison. I've just added some Samix brass front portal covers to my TRX Defender, have yet to give it a proper test though, but expect will see an improvement.
Francis great video, I heard you mention oil weights. would you mind recommending what shock oil wt you think would work best in a Gen 8 scout ii? This gen 8 has lots of mods all stainless HD links metal axle housings brass portals, metal gears, aluminum beadlocks among many other upgrades its around 9-10 lbs or so. Thanks for your help
Since your vehicle got a little heavier, make the shock oil a bit heavier as well to support it on climbs and descents (and sidehill). Stock is 30wt. so go 40 or 45wt.
I have a lot of brass and weight on all of my vehicles. Not only to make it crawl better but it makes the cars drive more realistic in my opinion. I just don't like the jumpy springy look and 'feel' of stock crawlers. On all three TRX-4's that i own i have four brass weights on the front and rear axles. I also use metal axle housings on all of my cars, the TRX-4's, the Bomber and the Wraith. It is just the way the cars move that i like the most of adding weight.
That's quite a big difference with the brass. I have the 5mm hub extensions on the TRX-4, but it does not really make much of a difference. I am really thinking of getting the brass portal covers for the TRX-4. Great video! It's very helpful! : )
That for confirming what I expected. My rigs are all metal underneath. As in axle housings, driveshaft an portals. Do you think I would still benefit from the brass portals. Front only.
Love the review, very interesting, how much brass is too much, u can get brass inner portals, c hubs, links diff covers etc, wonder what it would be like with all that. Thanks for all your work
I think it would depend on the truck. My redcat Gen 8 already has a front weight baias, so you don't need too much more weight up front. Also , if you want to also use your truck for trailing, then you don't want to over do weight either.
Adding brass has diminishing returns. Just keep in mind that the more the vehicle weighs the more strain is put on everything to carry that weight over obstacles. You can get to a point where u have added too much weight for your foams and/or your tires to maintain traction where they could before. So be careful where u choose to add weight and how much, its definitely better on the drive train to keep the weight on the axle itself and avoid adding weight to the wheels.
Hi, If you still have it, could you tell me outside diameter of 118g yeah racing trx4 brass portal covers, to see if I can use it with 1.9 wheels ? I asked it to yeah racing, but don't get any answer 😕
Wow cant believe you are using a Revolver motor they are powerful and very controllable....here in the desert area I do use a air compressor to blow out the motor the brass covers worked very well....
$39 SSD (150g) Brass Portal Covers for the Trx4 are clearly the best valued mod I made. I learned about them from your Ultimate Trx4 Sport video you all made in 2019.
That's music to our ears man. It really is a cool tool for scale, good looking bodies since one doesn't have to give up a good looking body to have performance.
l'm looking to install some weights on my trx4 sport & this vid here helps me a lot. But the spot where I usually crawl has some killer sidehill parts & some descending parts have loose gravel kind of stuff. Quite worried about how much is too much as I plan to focus on the front end of my rig.
I was thinking, what if someone made tungsten portal covers or weights, tungsten is the densest metal, and is pretty corrosion-resistant. It would cost a lot, but should help performance right?
It will only make a difference if space was in such a premium that brass couldn't make up the ideal weight. For every application, there is an ideal weight down low that is proportional to the vehicle. More weight has downsides of inertia downhill and hard to haul up uphill. It puts more demands on the tire to claw its way up. And ore stress on everyhing too. So maybe 50 grams on the hub is ideal. And a heavier material packing in 200 grams on each hub is not.
RC Review, could you do a similar test with the TRX6. I don't want to add a bunch of unsprung weight do to collateral issues, but if the performance while crawling difference was good enough then I would invest in it...
We've tested it and it doesn't make much of a difference in the TRX-6. The reason is when the front wheels go up in the air, the four wheels on the back maintain great traction and propel the vehicle up. And it almost can't tip over backwards. Really crazy what that third axle does.
The brass made a big difference in climbing. What tire foams are you running in the rear tires? Might it help a little to install a firmer rear foam? Nice video as always.
These are stock Proline foams on the rear. The best solution for a vehicle like this is Proline Dual-stage foam. A firm innner foam for support and stability and then a soft outer for articulation and grip.
Where’s the USA 🇺🇸 seller for this? Insane difference on the climb....CRAZY! Was thinking of putting a set of Capra axels under mine just for fun. Not keep it like that just play around for fun. Haven’t decided how I want to build mine yet. Really been looking for ideas and waiting for a few new products to show there self. Thanks guys
Feel pretty good about that. The effect is the same as using cheap plastic wheels and aluminum or steel beadlocks. If a wheel is light, 50-100 grams per wheel is good. Same applies to doing front only if one just wants to climb and help distribute the weight to the front. Rear wheels too, maybe a little less if vehicle is still rolling over forward a bit. The downside is stress on the drivetrain. Acceleration and braking are adversely affected too. Luckily in a crawler, this is hardly an issue. And with a well-built, robust drivertain, not a problem at all. Not great though for bashers or fast vehicles.
Too much weight down low can be harmful as well as every quarter lb added affects climbing prowess, braking, sidehilling, etc. A balance needs to be achieved.
The scx10 iii is more of a scaler than a rock crawler. The scx10 ii is more lightweight and better for crawling but the iii looks super realistic and it has a lot of cool features
@@RCReviewChannel foe me sofar they only give benifit. Only thing is you have to find yourself the best foams for your tires. Because of wraight gain. I do like heavy rigs I drive different underground. White Sand, Forrest ground, rocks and water/mud. Maybe there it's a down. Mud!
Definitely a balance (pun)…weight offers some increased traction, especially if you have the right foams and tires. Kind of a can of worms too, a rabbit hole if you will. 😆 I’ve come to the conclusion that improve until it’s making you nuts, then back off and just drive better. If the crawler can do everything it will become boring. None of us want that…

Chips ahoy cookies always taste better while watching Francis’ videos
Chips Ahoy of our childhood!
Very clear improvement. Thanks for showing that. I get tempted to get my Losi Comp Crawler working again. I remember it being capable when it wasn't just a roller. With some current electronics I think it would be fun.
Yeah, these are great tools for tuning.
I have one check out my channel. I put my capra shocks on it.. much better
The steep wall performance was an impressive difference 👍 Awesome videos as always.
Glad you liked it!
Maybe he can dial it in as good as the gen8 even :) :)
I could almost feel how much better the car was handling 😄 I didn’t know about the revolver motors... Thank you for the video! 👍🏻🙂
Another awesome video with objective performance differentiation. Well done!
Wow, thank you!

Francis... saludos desde Puerto Rico! Excelente tu canal 👍
Thank my friend.
Good video straight to the point with no pointless useless trying to promote youre channel info!! 👍
Thanks for sharing, very useful and practical comparison. I've just added some Samix brass front portal covers to my TRX Defender, have yet to give it a proper test though, but expect will see an improvement.
Yeah, they're essential equipment with a Defender body.
You can see the transformation right away . Those front wheels kept down much more after the weighted portals were added . Very interesting stuff
Cool huh. At the limits, it's the key difference between making it and tumbling down.

And what about brass portals at the rear? Would it make it worse? Some kits have all 4.
What is the minimum size rims you can fit on SCX10-3? And will the portal covers limit what size rims you can put on?
Do you have weights in the rims?
I have the RZXYL portal axles. Would you know here I can get replacement parts?
since the rear springs are softer than the front , how about putting a the axial yellow springs in the rear?
That for confirming what I expected. My rigs are all metal underneath. As in axle housings, driveshaft an portals. Do you think I would still benefit from the brass portals. Front only.
Do you do the covers for the front only or all 4 hubs?
Good job Francis. As always your video is so helpful.
Glad you think so!

The 1 oz stick on wights for tire ballances are cool way to add weight
I put the brass portal covering on my Redcat Gen8 Axe & steel wheels it made the world of difference
Brass front and back?

What weight oil did you end up going with? I'm getting mixed opinions 60-80wt.
Nice improvement! Not on the stock tires I assume? Watching at work so I may have missed that, lol.
What pinion and esc did you use with the revolver? How did you find wheelspeed?
pinion is 11t. Wheelspeed is good. Maybe 8-9 mph on 2nd gear. ESC Mamba Micro X
Excellent, Thank you!
running without a body might as well give up on the scale-ness. That's why I didn't get a summit, because I wanted the scale aesthetic.
Correct. We ran it without a body and it ran successful lines. But with brass and the realistic body, we were able to achieve the realism we seek.

This should really help out the Capra since it will balance out the weight of that cage.
RC Review thank you
Beef Tubes makes them in Ohio....
How do you feel on putting weights wrapped around the inside of the wheel on the rim?
Feel pretty good about that. The effect is the same as using cheap plastic wheels and aluminum or steel beadlocks. If a wheel is light, 50-100 grams per wheel is good. Same applies to doing front only if one just wants to climb and help distribute the weight to the front. Rear wheels too, maybe a little less if vehicle is still rolling over forward a bit.

@@RCReviewChannel thank you for the insight
Huge improvement in performance with the brass.
That body really is a hindrance.
These covers are one of the greatest tools when pursuing performance with a heavy body.
Are these only used on the front? Thanks for the awesome review
Yes they are. front only!!
What weight shock oil are you using?
teddlyt 50wt front and 60wt rear at the moment 😉
Where is your channel based out of?
What "mods" have you made to the 10.3?
We have 10 mods. Publishing soon.
So just to clarify you ran the revolver before and with the brass covers?
Yes, Revolver was used the entire video. The only delta is the brass covers.
@@RCReviewChannel very cool thanks for putting in the work.
I have $400+ in alloy axles and full brass portals for my TRX-4 and I must say it was worth it. It sticks any where, any time.
Too much weight down low can be harmful as well as every quarter lb added affects climbing prowess, braking, sidehilling, etc. A balance needs to be achieved.
Crazy huge difference
Great vid and info.
Glad it was helpful! Helped us to too getting closer looks while editing. We literally changed portal covers in the field!
@@RCReviewChannel what do you use as a cut off point for stopping to add more weight? I find it funny that some add every bass part that comes out.
Are overdrive gears next? Thanks for the great videos btw.
Yes, that's the 10th upgrade and just waiting for it in the mail.
RC Review I’m waiting for better tools from the mail to put underdrive on my gen 8 otherwise I’ve done all you’ve suggested to that truck
The scx10 iii is more of a scaler than a rock crawler. The scx10 ii is more lightweight and better for crawling but the iii looks super realistic and it has a lot of cool features
Try them front and rear, along with some OD gears, you think it climbs now....Yes the revolver can do it!
Really! Curious now. We are gonna try it today with some crazy SSD weighted wheels.
That's no question yes they do!
Any downsides?
@@RCReviewChannel foe me sofar they only give benifit. Only thing is you have to find yourself the best foams for your tires. Because of wraight gain.
I do like heavy rigs
I drive different underground. White Sand, Forrest ground, rocks and water/mud.
Maybe there it's a down. Mud!
50wt front 60wt rear right?
Yes. Our caveat is that's our first guess and it's working awesome so have not tried any other.
@@RCReviewChannel Thanks! Mine is on pre order still. Can't wait!
