So... two years after building my first Twin engine LIDL I have now finished my second one!

It's MUCH more powerful than the last one because I've used 2207 motors from my Diatone Roma F5 kwad. It gets its juice from a hefty 6S Sony VTC5 Li-ion pack which gives me over 25 minutes of flight time.

I got quite a bit of inspiration from the Twin Turbo Lidl build by Bavarian RC: https://youtu.be/YPsG6kbdEaI?t=1 . His CAD drawings of the Lidl v2 (linked in the video description) were a big help when putting my ideas on paper.

I've added a rudder to my build to get an extra dimension of control, but best of all I've put the (Caddx Tarsier) camera on a panning servo, controlled by the gyro in my goggles! This really adds an extra fun dimension to flying!

That's awesome, nice work!

Nice. I've always thought it would be cool to have a drone with the camera on a multi-axis gimbal, tied to my goggle's head position gyro... Huh, it's been a while since I've seen a "glider".

On a drone it would probably be very disorienting. Maybe it's manageable in Angle mode but probably too crazy in Acro mode.

On this airplane I actually enjoyed looking around most when I was in INAV Cruise mode, it's a step up from Angle mode and allows to make very controlled turns while holding the same altitude.

I'm getting a multi-axis gimbal with faster servo's soon - I hope this will increase the feeling of being inside the aircraft even more

There were some questions about the build on YouTube so here's a bit more information for anyone who's interested:

• The ESC's are slightly older Emax Bullet 30A where I had to remove a little capacitor to make it support DSHOT. Any 20+ Amps ESC which supports the battery voltage (6S in my case) would be adequate actually, as I rarely pull more than 15 Amps in total.
  

• The VTX antenna is a Foxeer Lollipop V3, connected to a Rush Tank Mini VTX mounted flush on the bottom of the wing (just like the ESC's) to get lots of cooling. For my next build I'd put the antenna closer to the wing root, because there's a particular angle at which the VTX signal is completely blocked by the battery. I'll also replace the antenna with a ProDrone Cloverleaf TX, which has a slightly longer cable.
  

• The FPV camera is a Caddx Tarsier which has a double lens; one for the analog image and one for the HD recorder. Sadly the Tarsier is not made anymore but if I ever had to replace it I'd choose a Caddx Ratel combined with a Runcam Thumb Pro-W.
  

• The 6S battery is made of Sony VTC5 2600 mAh 18650 cells. Molicel INR18650-P28A would be even better. In any case you need to use cells which are rated for 30+ Amps of discharge current, or a LiPo.
  

• I've recently replaced my 1700 kV 2207 drone motors with 1350 kV iFlight Xing 2604 motors. The lower kV allowed me to use larger Gemfan 6042 props, though I'm still using a 75% throttle scale as before, to limit the maximum current to about 15 Amps. At full power it provides an insane amount of thrust.
  

• The flight controller is a nice Matek F405-WMN. It's pretty small but has all the ports you can dream of.
  

• I used some really nice KST DS113 servo's. They were pretty expensive but I wanted to minimize the chances of a servo failure.
