    So, another day another little update...

    This euro doesn't come with a functioning rudder, which is a shame. They rely on the fact that you have thrust vectoring for yaw I assume, but I like to had a rudder for co-ordinating turns and slight cross wind landings. Plus it's supposed to have a rudder... so lets make one!

    The easy option would be to cut a space for a servo, cut out the rudder and hook it up.

    I don't really love the look of the servo horns sticking out the rudder however, and I want aerodynamic!

    As it happens, a chap on regroups discovered the servo for the yaw thrust vectoring is almost perfectly positioned to allow a rod straight down past it from the rudder above. This means you can run both the rudder and yaw vectoring off a single servo... lovely! I had to move the servo backwards ever so slightly and will post pics of that along with the linkages at a later date as I still need to buy some bits for that.

    Here's the rudder mod though so far. Obviously will be needing a lick of grey paint too!








    And a little more work on the cockpit... I've managed to move the camera a little further down, the view is now better to my taste... I Printed out some real eurofighter screens on photo paper, cut to size and then stuck them in place of the blank screens. No one wants to see a blank screen while they are flying! The little one for the standby AHI in the top right was a bit tricky to get right because it's so small! Still need to get some paint and just do some scale touches, but it's already looking much better to me.

    I've also modded the control stick to move with aileron, but just waiting on some 3.7g servos which will be doing the moving. You can see in the second pic the control stick extending down through the floor. This will then be hooked up to the 3.7g servo which will be wired up with the aileron output on the rx. Next up I need to make some arms and legs, and find some hands the right size.








    So, baby steps but it keeps on moving! Now considering using a LRS as well though and switching to 2.4ghz video.... It would allow me to fly lower and closer to trees etc which is where the fun's to be had. Plus of course I can use it on any future long range fpv platforms... and it means I can fly without too much fear of going out of range. Despite the limited duration, due to the speed of this thing I could happily fly a 6+ mile round trip too if I so wanted, so perhaps it's not so crazy. Decisions decisions...

    I don't mean to be a stick in the mud, but I hope you have FPV'd before? I have noticed that it's harder to tell when you're about to stall in FPV mode, and EDF's don't have the instant-on thrust like props do, if you get into trouble.

    Sweet looking plane though, I await your video.

    edit: just saw some of your other flights. Nevermind!

    Yeah I have, even I wouldn't be crazy enough to do this as a first FPV project.

    Thankfully deltas have very nice stall characteristics too, and I will be doing some testing to find out what the stall speed is at zero throttle... Since I have the airspeed readout I will be able to then avoid that during slow/low throttle flight. The other advantage this particular jet has over the typical EDF is the control from thrust vectoring. Where most EDFs will have next to no control in a slow stalled state, this thing will even with zero airspeed as long as there's some thrust on.

    I will be doing all landings line of sight initially anyway, as I think for belly landing it's preferable to fly in at high alpha with very low forward airspeed and flop onto the grass. I don't fancy trying that in FPV mode for now.

    Awesome build, I can't wait to see the first fpv video.

    What I suggest is leds in the cockpit maybe even behind the screen panels so when you're flying in the morning or afternoon the screens have this glowing wow feel to it, maybe even a light for the HUD so it glows green windshield. You can also try to put strobe lights on the wingtips so when you pan to see your wings them blink.

    you know I had thought about lighting up the dash but dismissed it as too time consuming and adding too much weight/complexity...

    however you prompted me to take a look at it again and I've had some ideas... watch this space!

    I also accidentally ordered an EZUHF today. Whoops. For now I'll be sticking with 5.8ghz for video but it gives me the option to change to 2.4ghz in the future.

    Maverick: Tower, this is Ghost rider requesting a flyby.

    Air Boss Johnson: That’s a negative Ghost rider, the pattern is full.
