    VAS Chimera V2 Prototype - Scott (Hoss) Build Thread

    Hello all,

    Alex has been kind enough to select me for a prototype run of the Chimera V2. I'll be documenting my build as well as maiden along the way and posting it here. Since the main differences in the airframe are not structural, I will be also including my own techniques and modifications that I use on all builds. Note that any deviation in build is strictly my preference and that the standard build per VAS instructions produces a solid wing - I have a tendency to try to fit places that I don't fit while going really fast, so I may spar and laminate more than the average builder. It holds more battery out of the box and has several other differences. The V2 is different from the V1 in the following ways:

    1. Deeper and wider battery bay, allowing for 4S setups out of the box
    2. Wider mid section (due to the wider bay) bringing the wingspan to 57"
    3. Symmetrical Airfoil - Faster top end and larger flight envelope
    4. Mid wings are narrower and have a steeper sweep backward
    5. Stabilizers (both mid wing and winglets) are made from 1/16 ABS. The mid wing stabilizers are embedded in the wing rather than glued to the wing surface
    6. The camera box now includes strap slots to hold your gopro / hd cam in

    So, without further ado, I give you my Chimera V2 build.

    What came with the kit (this may differ from production kits):

    Foam, glue, stabilizers, motor mounts, spars, quick links and control horns, bay lid, camera box and front skids (6mm)








    I began by measuring out my FC, marking and cutting out a bay for it as well as my receiver and current sensor











    I then deepened the groove for the bay lid so it sits just below flush










    Then I laminated the equipment bay with 10mil to provide a solid surface to mount my gear on







    I then covered the bay door with vinyl carbon fiber print adhesive to give it a sick look (normally would have done cosmetics last, but just got the rolls and wanted to test Looks pretty sick though I had 2 different kinds, so I laminated both sides with it to see the difference









    I then cut in my wiring channels for the video system into the mid wing and throughout the battery bay







    Next I will be installing the camera box, then gluing the airframe together.

    Using the camera box as a jig, mark out your cut, the cut out for the box.











    I heavily goop the front of the camera box as I use it as a grip to launch. I feel it helps with the repeated pulling on the ABS.


    Also, I like to scuff up the ABS before I apply glue. A rough surface accepts glue much better than a smooth surface.

    Great documentation Scott Neat building!
    The Chimera was my first fpv ship, and I had good times flying it. When I built my Chimera I knew nothing about fpv, so I went for a 5.8ghz omni setup. LOL. Stupid I know.
    Anyways... Its a great pilots airframe. I bet it will track even better at high speeds due to the symmetrical airfoil.

    Thanks. Yeah, I'm still going to keep my original in service for now, but really excited to see how I can push this thing. Just spent 60 bucks on a really nice, big cobra motor for it, so hopefully it's a rocket.

    Just a sidenote.... . Since you enjoy smashing through trees so much. Have you seen this thing:

    I bet it will have good twig penetration capabilities.

    Dude, that's awesome! Totally getting one! I have all the hardware needed already and it's so cheap.

    Embed some small spars in the Chimera wings leading edge. It will blast right through twigs and small branches.

    If it is broken, fix it. if it isn't broken, I'll soon fix that.

    We're on the same page - ordered some 6mm flat spars today to slide into the leading edges. Also going to wrap the leading edge with 10mil over the standard lam. It's going to be indestructible. I'm really liking this new version. Got a really nice motor for it today and going to do something different with the bay lid as well.
