    Default CubCrafters Ventral fin install

    Does anybody have any documentation or knowledge on how the ventral fin on the EX-3 is installed? Engineering drawing? Pictures? Ideally I would like to weld a tab on before cover. That area gets a lot of spray.

    Thanks,
    Gregg

    It's in the EX dropbox folder under miscellaneous and Float Installation.pdf.
    I presume it won't have changed for the EX3.

    Are you able to send me the Dropbox link for the EX? I only have the EX3 link and there isnít a float manual in the misc. section.

    Thanks,
    Gregg

    I'll email you the PDF. I understand CC are not keen on sharing their dropbox links. Though I expect they would respond to your personal request.

    Guys Ventral fin on bottom of fuse was used on the Sport Cub CC11 with Baumans and is part of the drawing. There is none noted for the CC11-160 or CCK with 180HP on Aerocets. There is one however for the Top Cub, CCX EX/FX3 and the XCub with either Claymar or Whips. I have experience with all of these recently.

    The only potential issue Cubdrvr2 notes is beaching, and that only an issue if the terrain is tail high.

    Ventral fins are butt ugly and limit where you can beach your aircraft heel first. It's difficult enough without the fin to pull your tail in even on a beach with a steep bank, add shoreline brush and rocks and your never going to play or camp where you want with a bottom fin. I would check the flight stability before adding one

    No welding required, the ventral brackets are designed to bolt in to a covered airplane.

    Pete,

    Is this fin needed on an EX2?

    I am planning for floats this fall and have seen CC cubs on floats with and without this ventral fin.
    I plan on Clamar 2180 amphibs, I am 1865lb EX2

    Thank you,

    David

    From this drawing it looks like you need at least an Adel clamp installed before cover. I was hoping to weld tabs like I did with the water rudder pulley attach points. Does the ventral fin interfere with the inspection panel?
