    Decided to start another FMAR build this week and took more photos of what I do to the chassis while building them. Hope you enjoy!

    I like to use tape to give myself a guide while I cut the chassis. Makes it somewhat easier to cut straight with a dremmel.

    This is the finished product after cutting everything and cleaning up the rough edges with a plastic specific file and exacto.

    This is a little trick I saw on a YouTube video from Dribar, the World Champ does this to his FMAR setups. They split a piece of carbon and half and glue it on the sides of the front of the chassis to stiffen it up after you cut it down. FMARs are prone to break near the motor mount due to the increased weight in the front.

    Detailed photos showing the pocket I cut out to accept the CF

    The next three photos show the Flex you achieve by doing these chassis mods. A lot of builds in the Tamiya Racing world rely on trying to make chassis Flex when they land, giving more room for error on a jump.

    Phase 2 coming in ! Photo heavy.

    My color scheme.

    I've seen many Japanese racers cut the battery clip like this in order to allow the chassis to Flex still once the cover is on.

    The rear switch cover has to be trimmed as well, to allow for the batteries to be inserted in reverse as well as clear the rear/front of the car when you bolt on a rear bumper.

    This is a little trick a lot of veteran racers do with foam behind the terminals so you have more contact with the batteries.

    Finished and cut battery cover as well as switch cover.

    IMG_2358.JPG
    Fitted on. The smaller section of the battery cover will be glued in place

    These photos show the Flex the chassis still has even when the batteries are installed.

    Where'd you get those orange rollers? And how much were they? I've been looking around for those here in the Philippines and so far I've been offered copy rollers huhu (orange is one of my favorite colors sooooo)

    Daaaamn, based on how they look and how they perform (based on that one vid where Z3n bluster had em) they're sorta worth it....?? Although I was able to get 3 pairs of orange ringed 3 spoke aero rollers from a local store here hehe

    I decided to try a flex build, I've been wanting to try for a while. I took the chassis from my suspension concept car and may have taken it a slight too far.

    Wasn't thinking too much about the colour scheme to be honest, just using spare parts that I had lying around.
