    Got my spare motor! I have to give my both thumbs up for Getfpv.com, both earlier and latest orders were shipped out the next day and in 10 days were at my door, super!
    As I had everything ready I slapped my gear on in no time. I raised GPS slightly above the cam and underneath made ground plane for it and grounded. Used thin plastic and copper tape. As much as I know these cams are not noisy for GPS, but it has compass as well which would be affected by the cam. 1 gram extra for a peace of mind- worth it

    It looks organic. Freakin bug:-) If you get aerodynamic instabilities (not saying you will) you should try a run without any go the plastic fairings. Might give you the golfball effect.

    I'd say those fairings will come off in a first crash anyway...

    Thanks for the update. It looks amazing! Very small as well, I think you will break the record with this.

    Tube/ESC covers are on:



    Like on V2 for canopy I sculpted around the gear with 3mm balsa and filled with dark coloured plaster. This way I know my minimum inner size of the canopy and when to stop sanding filler, which is beige color:





    After few sessions of sanding/filler/sanding I got the mold ready for vacuum forming and failed... Some clear plastic I had became so brittle after forming that it was just coming apart in my fingers. Neither I have another plastic or the time for experiments, so I went for epoxy/fiberglass forming. And it didn't turned out as heavy I as I thought it would be:



    With those air vents for Vtx it looks a bit like alien's back



    I'll set OSD tonight and make a launch stand, then I can set FC. V2 is gonna have it's last run within few days, then I can take prop adapters from RCX motors and put them on V3's KDE, which originally has only 4mm shaft adapters. I can put rings to bring them to 5mm, but visually they look weak. And then we go for V3 maiden

    A friend posted me a link of a quad supposedly having 185km/h max speed... To me it looks like just a badly cut and exaggerated add, but I wrote them and asked for a video proof

    Boring commercial. Yawn! I doubt they will even bother to respond. Your quad looks amazing btw.

    Cheers bro, welcome aboard!
    Yeah, I have high hopes for V3 as my V2 just can't break 160km/h... Went for another run this morning with props that I didn't fly yet. Tried 4"BNx3blade and it seems that they can do most but still, 161km/h and can't get full throttle as quad "loses grip" in the sky as soon as I go close to WOT or quickly release throttle. Turning down PIDs is not helping and I don't know where to look for troubleshooting I'm failing... I'll try without Oneshot as I presume when it's on it has breaking enabled as well for ESCs. We'll see within a day or two.
