I'm always on the look out for new and exciting things. Saw this awesome design is by Peter Ryseck and had to build one ...

Can't say enough about how adding wings changes everything. Quad-Mode Flight times are around 3-6 minutes dependnt on LiPo and props. Bi-Plane mode effectively doubles the flight duration. For those wondering, yes the wings do provide signifigant lift. So much so that a slight breeze can send the MqB climbing rapidly despite the props being 100% horizontal. Please be aware that I'm still waiting on the video switching circuits and thus I've only 1 camera installed. Not really liking the current VTX antenna placement but it works and hasn't been chopped off yet so alls good right!
Thrust to Weight is aprox 7:1 @ 150 grams + LiPo (77g Tattu 650 mAh 95C)
Side Note: I'm working on a version of the MqB that uses 1S 18650 LiPo's. Should be along the same lines as Dave-C's LR-Nano Quad but with wings. If i can make it work, "should" be able to double the flight times. (Edit Just attached a photo showing the work for this)

wow, really interesting. what firmware are you running on? INAV? is there some mode/mix switching betwen vertical/horizontal flight or is just the same?

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Fascinating design, how is your camera mounted? It looks like it's resting on the standoffs in the 2 shots where we can see it, with the canopy off. I assume it's not screwed into the canopy, what with the magnetic canopy closure, and all that. Is it glued down? Is there some part of the bracket it's wearing that I can't see?
Camera is attached via double-sided tape to the VTX (Should see this on one of the photos) so that if the canopy comes off it wont take the camera with it. Check out the newly uploaded photo... Thats the 1S nano variant I'm working on.
Neat!
So I had a few thoughts: you say that you aren't thrilled with the vTx antenna placement (I assume because it's on the bottom, during forward flight, and it's likely to be the first thing that touches down when you crash). Why did you put it down there? Were you thinking that you would get better reception from it, since it wouldn't be broadcasting through the drone to get to your goggles? With the range you can get with your current radio gear, you don't need to worry about that. You can easily make the side with the vTx antenna the top of the quad, would only take you minutes.
Why do you need a camera switcher, btw? Is the current camera at to high of an angle to fly with? Why not tilt it? The current orientation doesn't look usefull for any mode of flight I can imagine, using that hardware.
The canopy's wire channels are not quite sufficient to allow the VTX direct routing to the other side. Then also consider that the canopy is designed to detach during a crash to absorb some of the impact forces. Thus cutting through the canopy to allow a cable to pass would stop the canopy from detaching properly. Peters update for the canopy should make this a bit easier but its not been released yet.
The other-side as you called it, is for the FPV camera during Quad-Mode. Its mostly used for landings and take off before switching to the camera at the front of the canopy. During Bi-Plane mode the canopy-cam is the primary feed but requires that the video is manually changed using a video-multi switch that triggered via the remapped LED pad.
I've yet to receive the switching circuits and thus I've only installed the canopy-cam. If that failed to show soon, i may opt to buy the Matek F722-mini as it has on-board video switching.
I neglected to mention that Peters latest update allows for a 20x20 VTX to be externally mounted. This should help with some of the wiring routing as well as keep the VTX much cooler. The new location will be to the side of the battery stand offs. Which should make it very unlikely that the VTX will take damaged during a crash as the arms / wings take most of the impact. Which as you know the wings come off on impact to lessen the amount of force the frame takes.
You could use the current vTx/antenna mounting, and flip the whole thing, so the antenna came out the top. Flip the FC 180 deg in the configurator (on the yaw axis), take the wings off, flip them over, reattach them, pull the cam off the vtx, spin it 180 deg, stick it back down (or use the cam controls to flip it in the firmware). Boom, same hardware, now the antenna is on the top.
Cant do it as the canopy is made to fit from only one direction. The update corrects this issue by mirroring the wiring channeling on both sides.
What I suggested does not involve rotating the canopy, and mounting your boards on the outside of your aircraft causes a host of problems :(
@Jodie Froster - still offering unsolicited advice with zero builds on this site I see..........

Knock it off! Last time i checked, anyone can post here so long as they"re civil. If you have something sour to say, use a PM like an adult.
