    For someone picking back up the Mini4wd, I am really confused to what plates (FRP) to get and to start with? What constitutes a good buy in terms of FRPs, since they aren't cheap.

    Kinda depends on what kind of car you want to build. Do you have an idea of what you want to build? If you could link a picture or something I can tell you which FRP pieces to buy.

    Is there an alternative way to cut frp plates without using a rotary tool/dremel?

    True Value or Ace Hardware usually carries those types of products here in the Philippines! Although majority of them will be in a different brand.

    IMG_7508.PNG Anyone know how to make this? I saw this through the Con-d'Ele app and it seems legit

    Any more pics or link to where you found it?

    I've had a similar idea come to mind before about using bearings to actuate the body damper, it looks like this might follow the same principal with bearings on the possibly on the wheel axle.
    In fact...hold that thought, I think I might have an idea.

    EDIT!!!

    A quick simple mock up of how I believe it works. Like I said, it's an idea I've toyed with before.

    Also, you'll note that the damper arm is attached at the bottom of the cross bar where the weight sits (red ring).
    Because that sits below the battery, you'd have to mount a support crossbar at the top (green ring) that will sit atop the batteries. I wouldn't rely on just the shell acting as a cross bar.

    Damn, seems complicated but it seems doable especially with the use of shaft stoppers aswell, there isn't any much more info I can give as of now about it since I just saw it in the Con-d'Ele app, I'll try to research further and I'll probably post about it when I get to it. Thanks a lot hehe

    Found the guy again, mad props to him and he seems to make a lot of cars, I'm not sure if this is the same system as his ver.3 car but it looks very similar and damn, it weighs like 83 grams. IMG_7515.PNG IMG_7516.PNG IMG_7517.PNG IMG_7518.PNG

    That's an older version of his setup I believe. These are pics of his newer setup. It doesn't actually pivot on the axle, the whole brake bar and body damper is connected and moves up and down on a screw. He's got so many different variations, you can follow him on instragram @ masamini4

    He has some videos you can watch, that will wrack your brain a bit.

    This is a version of his setup from the bottom view.

    I get it now.....just watched 2 different videos he up loaded.

    Basically the 2 bottom rings are poles using spacers to create a shaft, the 2 top rings are are holes with a fitting to allow the body damper to slide up and down the shafts in the bottom ring.


    I'll just show with my car. See them green rings...

    I've held my body damper in place with 2 locknuts. If I were to open the gap between them and put a 6mm spacer there, that's basically what the body damper is, but mounted to the bottom rear stay screw holes.

    Well, what do you guys think of it? Personally I haven't tried it but I have a new super 2 build coming up and
    I'm not sure if I should try that damper type yet

    Watching a video of it flying round the track, it looks like a good solid option. But there's pros and cons to everything, and I think the con to this setup could be the rear brake activating more than it would on a static rear brake, everything sending the body damper up is going to have the brake hitting the ground. Just something to consider.

    Hello guys i'm looking to get the Exflowly red special just for the chassis because i like the color. The box says it is "ABS Resin Monocoque Chassis (Red)". I currently have the MA Reinforced Chassis white which is ABS high polycarbonate ABS resin reinforced chassis.

    The question is what is the difference between the two? And is it worth the upgrade?

    Thanks in advance!

    Reinforced uses a slightly different material with slightly different design support fins in order to make the plastic stronger.

    "ABS Resin Monocoque Chassis (Red)" is basically saying it's stock plastic in red colour.

    This is the MS front bumper just for reference of difference between stock and reinforced.

    You'll notice the reinforced bumper (top in both images) is a dark grey instead of black due to the slightly different makeup of the plastic. You'll also notice that the design of the bumper is slightly different to the standard and in the bottom image you can see the added support fins in the bumper area.
    Just ignore the silver marker, it was a guide for me trimming.

    Being new to this science, I've watched dozens and dozens of videos. The knowledge required to tune these cars is immense - that's what makes it rich and interesting.

    My question is: Have guys like Zen Bluster and Mad Tang considered contacting a publisher and writing/documenting a Tamiya Mini 4WD tuning manual? I can't imaging it not being successful. I fear this knowledge could be lost.
