    Some additional useful information/links

    Recommended Propeller with the SS motor pack: APC 11x7 E (pusher not needed)

    Suggested CG and Min/Max AUW (for the metric guys): The CG is 3 to 4 cm in front of the main spar, so measure from the cap slot forward on the bottom


    About the Eagle Tree Vector:


    Quote Originally Posted by Hoss
    "The gains on the vector do not affect manual flight - they only affect controlled flight modes. They don't affect how the aircraft responds to your input, but how the vector responds to any forces (wind / turbulence or your releasing the stick). As long as you have stick input in a particular axis, it's letting you have control up to that point of input and not fighting you. The gains control how hard the vector will work to return your plane to level when it is affected by outside forces or you release the stick. At 100% it's going to punch your plane back to level (and probably over-shoot it, then respond in the opposite direction just as forcefully, causing oscillations). At 0%, it's not going to return your plane to level at all. I find that the default 50% is perfect in the setups that I have.

    The setting that controls how smoothly the vector will follow your stick inputs is "stabilizer responsiveness", but again, this is only in controlled flight modes. At 10 things will be very twitchy when in a stabilized flight mode, at 1 they will be mush. Again I find that the default value (4) works very well for my setups.

    If you're flying manual (by selecting "stab off" or by turning the gain knob on your tx down to 0 which reduces all gain settings at once), your control is 100% dependent on your tx setup. The vector is merely there at that point - giving you a nice osd and essentially working as a "pass through" for your receiver. The gains and stabilizer responsiveness have no effect. It's your rates and expo at that point that need to be adjusted if you find your model is twitchy in "stab off" mode."

    In a nutshell, if changing how the plane feels to you in manual (or 2D for that matter) with your input from your transmitter is what you are after, you should get it flying nicely by adjusting your transmitter settings. The vector is for stabilization, among many other things, but models that have vector still require that you set up your control (rates, expo etc) just as you would any other model. It does not take over or replace your tx / rx / servo setup.

    For twitchy, leave the defaults in the vector, adjust your expo. I have landed on 65% expo for aileron and elevator on the Drak.

    Edit: I wanted to note that my throws are much more than the recommended throws - so 65% expo is different for me if you only have 1" of total travel.

    More info about the "Vector for Fixed wing" look for the thread on RCG: http://www.rcgroups.com/forums/showthread.php?t=2196588

    TARANIS Users
    Throttle Cut on the SC switch in order to avoid the throttle spinning when accidentaly hitting the Throttle switch.
    Cutting the Throttle will also reset your timers.
    Activating the throttle will activate your log too.

    It is setup for being used with the ET Vector.
    Mode and Submode are respectively activated with SE/SG
    Also added the PAN/TILT switch for the camera LR/LS

    Additional components used on my build:



    Additional supplies:

    • Hot Glue
    • Gorilla Glue
    • Plasti-Dip (color(s) of choice)
    • Shrink tube
    • Servo lead extensions (or UTP CAT5 cable is perfect if you create your own extensions)

    @gobigdale

    Is this correct as the info we have had from the previous thread is slightly different

    Included in Kit


    • EPP wings and fuse set
    • 2 - custom made Cf spars with Glass slip tube sockets
    • 8 - 2 mm FG rods for fuse and wing sparring
    • 2 - 4 mill coro verts
    • 2 - 4 mill coro winglets
    • 1 - 2 piece custom made T6 CNC aluminum motor mount with 440 screws and lock nuts
    • 4 - aluminum lid hubs with black nybolt thumb screws
    • 2 - lengths of 2 mil coro for lids and saddle bay doors
    • 1 - Strip of velcro to join wings to fuse
    • 2 - 2''custom balsa elevons


    I've read here that it was 6mm for the verts and winglets and 4mm for the fuse.
    Elevons are also made of EPP but only some seem to be available in balsa.

    Maybe it's too late to edit it, but you might want to include "Drak" in the thread title to help others find it.
