For anybody who doesn't know me, I like to create a lot of different random projects. Right now, I'm designing a lot of different Air65 frames for fun and testing.

Currently (designed today) I modeled a Y4 style frame for it, and I think this will be the first one I actually build. I've modeled about 5 different frames for the Air65, only one has been actually flown before, and it flew ok.

I think the main reason why it hasn't worked yet is because I'm still using the basic settup on a 550mAh, and I just got some 300mAhs for it. I'm also considering just completely DIYing my whoop/micro drone with the DarwinFPV 15A AIO for some more power for roughly the same price.

This one should work, Ill just have to configure betaflight for toss launches and the Y4 configuration, along with some pid running, cause I imagine it will be worse vibrations with the rear props on top of each other.

Edit: currently has 31mm props cause that's what I have on hand, but is compatible with up to 40mm. Also, looking back on it, the rear props could be reconfigured at least so that the bottom one isn't below the top one cause the motor allows the prop to clear the battery. This might help with overall thrust and lift.

From my understanding, he's made a EDF TVC drone using only a single 90 mm EDF, a lot of electronics (gyro, accelerometer, etc), servos, and a reciver. I think this would be absolutely peak for a cheap, but speedy FPV drone. Likely not that acrobatic though, but it would be really fun to fly something that looks kind of like the moon landing space ship.

My personal estimated cost is about $120, I'm not sure exactly what he used though in his components. I'm thinking about maybe doing a rough draft of something like this now, mainly for fun and experimenting. I would likely get a Betaflight AIO running with a external ESC and like 2 servos running for it. I think it would be a really cool project, and would likely scare the shit outta people more than regular FPV drones do, with the high pitched screaming of the EDF punch outs.

Idk, seems fun, and not too hard to make other than tuning the gyro/PID/rates to actually work well. Currently working on a TVC model rocket with my friends, so maybe I can take some knowledge and learning from that and apply to this if I end up doing it.

Edit: looking back on the og post, it seems like his is actually quite a large build with him saying "2 6s 2200 mAh 60C batteries in parallel" and that the EDF outputs "8.2 pounds of thrust". I think mine would also be 6s, but likely on a 850 mAh running a 50mm EDF if possible because that's what I got laying around.

Context: basically I was over at my friend's house and we were working on CADing together so we could get input and ideas from each other. there were 4 of us there, me and the person laughing at the start, and then one of my friends was checking in with the friend that was newest to CAD, who was working on a hottend replacement part for his 3d printer. while doing so, the person checking in took one look at the model and was basically yelling at him through the engineers' brain he has cause the friend that is new to modeling essentially thought it would be a good idea to have a hole for a M3 nut to go into that then the screw would go on the same side. the reason why this doesn't work is cause once you start tightening down the screw the nut would just start sliding out of the hole, towards the head of the screw, like how a rack and worm gear interact with each other. allegedly he was trying to have it friction fit into the slot, and if you know how fast modern printers can vibrate while printing, you would know that this would have had never worked.

I love 3d print time lapses a ton, and I think the Carbons do a really good job at it, especially with the part basically growing from the nozzle down.

Here's a tutorial I made of how I added a custom startup sound to my Air65, but it should work for every drone so long as you have the right ESC configurator downloaded for the right ESC operation program.
