Thread: U-31 MILLER HIGH LIFE 8th Scale build thread

  1. #1

    Default U-31 MILLER HIGH LIFE 8th Scale build thread

    Gents, I'm making a lot of progress on my winter project U-31 `Miller High Life' Unlimited Hydroplane. Based on the Lucero designed Circus Circus platform, the`Miller High Life' was campaigned briefly on the 1988 Unlimited circuit. The scaled down 43" hull will legally meet all overall dimensional info provided on the NAMBA MHR#8700.

    I inherited this project from a good friend as a plywood framed skeleton from Newton #146 plans. Most of the wood frames were disguarded after being used for patterns in favor of stronger G10 Epoxy sheet composite. CF angle will also be used for structural support, plywood Transom & Sponson bulkheads are G10 skinned. West Systems #610 2-part epoxy is used for bonding and Z-Poxy for sealing a bonding any wood to wood component. The center section of the hull has been offset from Port to Starboard for FE clockwise racing. Epoxy Glass Canopy, Cockpit and rear Wing Set(on order) are RC Boat Company pieces.

    Power will be provided by IMPBA NAMBA legal 1527 1.5y on 10s1p lipo. Offset 3/16" cable driveline and hardware will consist of a combination of Zipp Kit(turnfin) and Speed Master(rudder,strut) components. Same hardware and driveline setup is used on my U-1 Atlas Van Lines.

    Heres some pics so far showing rear afterplane tub construction. Everything is swiss-cheesed to save weight. Working my way forward to start soon on front sponson & canard spar structure.

    Ken,
    Nice job. Makes me itch like crazy just thinking about cutting all that G-10. Great idea though.

    Great build! That is very cool! Can't wait to see it finished!

    Very nice. The canopy will really set it off.

    Default Picklefork Structure

    Worked on locking down the front sponson structure. The (2) CF angles are tied together with hardwood beams bonded to inside sponson walls to eliminate pickle fork twist. The forward CF angle will be part of the nose canard wing structure while the rearward CF angle will support the sponson transoms tying them in to the tub.

    Sponson bulkheads and stringers next...

    I bought these decals back in the 80s
    and never used them.
    just realized these are for the Miller American
    not the Miller High Life.

    Working on the sponson bottom structures today. The West Systems 610 2-part epoxy i use on the G-10 takes overnight to dry so I try to setup something up for bonding as frequently as possible.

    Hi Ken,

    Looking good! Do you have a bare hull weight target your working towards?

  20. #20

    Default

    I'd like to keep the hull under 5lbs, I know its going to be tough.

    The deck, bottom and ride pads skins will be G10

    Vertical sponson and after-plane non-trip surfaces will be Styrene sheet to keep weight down.

    Bonding the engine cowling support opening structure.

    Heavy swiss-cheesed hardwood Airfoil blocks are bonded in. These really strengthen the whole front canopy/sponson structure to the afterplane.

    Canopy nose construction up next...

    Hydro Strut `G10 Wet Box' fabricated with a hardwood base is bonded, fastened to the hull bottom and transom. This is a long strut setup on offset driveline, angle-depth adjustment bolt will offer ease of access at deck surface. Faux`Turbine Exhaust' tube will hide any strut hardware proud of the deck.
