  • Eagletree OSD

    Today my Eagletree OSD Expander arrived!

    It looks nice and comes with a very nice manual.

    Time to fool around with it a bit before I mount it in the plane.

  • AitT V.2

    My old AitT has now retired after a work related accident involving the ground.

    This is going to be its successor:

  • FPV Maiden!

    Woho! A successful maiden!

    Pushed the range a bit to about 3km without a problem with either the RC or video connection.
    I also tried aiming the RC TX away from the airplane to see how wide the beam with was, and it was surprisingly wide

    It was verry cold after 15 minutes in the wind at -9°C, as you can se on the landing

    A FPV Easystar is born

    Now its time to start the build of my new FPV Easystar!


    I started out with some 2mm carbon rod to stiffen up the elevator


    Nice and flat after sanding som exess of


    I also added a 6*1mm carbon strip to stiffen the rest of the tail (I dont like flex )


    Some 10*0,5mm carbon strips in the wings


    It adds a lot of strenght to the wing


    I also added a washer thats 18mm across and has a 8,5mm hole so ensure that the carbon rod that goes in to the wing doesn’t ware on the epp hole and make the connection sloppy.


    Melting away some epp with my soldering iron (I use a diffrent tip for this)


    6mm carbon rod glued in


    I use a layer of heat shrink on the motor so that I don’t have to glue the motor itself to the EPP


    Melted some extra room for the wiring to the ESC


    Making myself a new rudder from the start


    Made frome lightwheight plywood


    Monocoated it with dayglow orange


    Du-bro hinges are so sweet

    Since the range of my video TX is much further than my RC link I thought that I would increase the range a bit.


    To do this I will replace the stock 3dBi Omni antenna with a 9dBi Patch anenna.


    I decided to change the SMA connector to a U.FL to eliminate the losses that comes with having long wires and multiple chain connectors.


    Re-assembling the patch.


    The patch in place and hooked up.


    I’ve used this LiPo in this transmitter for over a year and it has worked flawlessly.
    I use a diode in series with the battery to lover the volts by 0.9V.


    I made a step-up converter to be able to get rid of the 3s500mAh battery I used before, and since I fly on a 3sA123 I need to step-up the voltage to 12V to power the video setup.
    Sorry for the messy layout but I didn’t feel like making a new board after adding the necessary filtering.


    I had to sacrifice looks for performance when I mounted the FASST antennas.


    One of the two gyros that is going to help me get a nice smooth flight in a little more wind
    The other gyro hasn’t arrived yet, but it’s going to be mounted at a 45° angel to get best performance for the rudder.


    Heat shrink on the servos to not have to glue directly on the servos.


    Just before the gluing of the fuse.


    Glued.


    Tail glued.


    Push rods mounted.


    Servos in place.


    6*4 Prop mounted


    EZ-Pod before.


    After.


    Painted silver (Looks a lot better IRL)


    Added magnets for security.


    3sA123


    All Up Weight (AUW). This is with the FPV setup.

  • FPV över Hjo 2/1 -09

    • Airframe: Multiplex Easystar
    • RC TX: Futaba 6EX FASST 2.4GHz
    • RC RX: R606FS
    • Camera: KX-171
    • Video TX: 1.3GHz 300mW, stock antenna
    • Video RX: 1.3GHz dual output
    • Video RX antenna: 8dBi linear polarized patch
    • Video capturing unit: Sandisk V-Mate
  • Non FPV maiden

    I maidened it without the FPV setup to trim it out and test the gyro. (It makes no sense in crashing the FPV setup when not flying FPV)
    Everything went fine and it didn’t need a single klick of trim.
    If flew awsome!
    My hands could not take the cold for verry long so the first flight were about 4 minutes.

    Now I can do the FPV maiden!

    The build draws to an end…
