  • "Fly Classic Proxy" Approved Chassis/guide mods!!

    Hi folks, I did run this by Zack prior to posting, and this Modification has been approved for the upcoming Fly proxy.......a good mod. whether you a re entering or not

    I posted this a couple of years back on the old Forum, and with the upcoming Fly proxy, I am posting it again, for those that missed it.

    One of the issues on the Fly chassis (actually on most plastic chassis') when running without magnets is the lack of sufficient guide rotation.....this is not an issue with magnets, as even with a small slip angle, the magnets lose contact with the track rails, and the car deslots. Without magnets, the car can achieve much larger slip angles and the guide often "bottoms out" on the chassis plate, with one of two things happening....when the guide pounds into the chassis, either the guide blade can break, or , worse the guide tongue post hole support will crack/ break.

    From a performance perspective big slides will result in the car "bouncing" on the guide/chassis stops, which is not the hot tip for quick/consistent laps.

    The following is a quick/simple fix, that will not only save your chassis/guide from breakages, but, will result in a car that is smoother/more consistent at the limit.

    I have done this mod, on many many Fly (and other chassis) for club member/shop customers with no issues will not weaken the will eliminate breaks

    Same shot from above......the "ears" of the guide, bottom out on the chassis plate far too early.

    On the next shot, I have marked with a Sharpie the area of the chassis plate to be removed,

    I usually use a Dremel with a round burr/sanding drum, but, You can use some round files, or a Hobby knife ...remove a bit at a time

    Guide installed.............almost double the degree of more breakages, and a nicer car to drive hard ......."Priceless "

    Thanks for the tutorial Chris. I allowed this not only because it makes the cars more fun, but also because there is the potential for breakage when the guide is constantly being "snapped".

    I will update rules page.
