This video demonstrates a lightweight 3D printed EDF (Electric Ducted Fan) aircraft that achieves high speeds (over 100 mph) even at low throttle settings (30-40%), featuring strategic material density variations (4-6% infill) for structural optimization, hot-swappable battery capability, and the ability to glide effectively, showcasing how 3D printing enables rapid prototyping of custom RC aircraft with tailored performance characteristics.

More Fan Cat FlightsAdded:
What's up guys? Okay, we're back with the pushy cat or the fan cat is what I'm calling it now.
And uh I'm just going to get two more flights in. I've been uh short changing you guys on my on my builds.
Uh because I've just been I've been busy with my other businesses. So, I uh I don't have a lot of time to come out and do a lot of flights. Let me go see if my zoom is right.
That looks good.
So, I don't have a lot of time to come out and just rip.
But today, I have a little bit of time between work.
And yeah.
Get a flight in.
Rip around a little bit. I'll do two quick batteries.
Need some glasses.
Buzz the tower.
So fun.
>> So fast.
This thing is so fast for a 50.
That's 30% throttle right there.
This is so cool.
Off throttle.
Going to have to walk through long.
>> [snorts] >> And you don't have to worry about any prop strikes on the ground cuz it's an EDF.
Okay.
Do a hot swap here.
One thing I always forget to do is bring a battery with me my pocket so I can just continue.
Got to initialize.
Oop.
Okay.
Let's zoom.
Zoom in a little bit more.
Uh, hopefully I keep you in frame here.
Okay.
All righty, ready?
So fast.
It's got to be a well over 100. Has to be.
Oh, yeah.
I think this thing would be super cool with a bigger fan in the same plane.
Like the Freewing 64, this thing would be a freaking missile.
I may do it.
>> [laughter] >> It just hit me.
Ooh. You know when you blink your eye sometimes you get like you go blurry cuz you have like something in your eye?
It just happened to me.
And the weird thing is that my it it's only in my left eye, but it's making it so like I can't see. Ah, really weird.
This thing literally can fly around at 30% throttle.
I'm at 40% right now.
>> Full carving.
This is painful. Ow.
My eyes really hurt.
Kind of want to just fly it over there.
My son actually flew this yesterday or the day before.
And uh he absolutely likes it.
He said, "Can I have it?" I'm like, "Okay."
>> [laughter] >> Ooh, I think I just hit the the turbulence from that glider.
That was That was weird.
All right, I don't want to get in his way.
>> All right, I'm going to go downhill.
I'm going to bring it in.
This thing really likes to glide.
This should be about uh I'm going to overshoot.
Ooh. All right.
All righty, that was cool.
A little painful without sunglasses.
My bad though.
It's just it's crazy how small this fan unit is for the plane and how light it is. When you guys print this thing when it has to be an active foaming lightweight PLA, I tell you that guys that all the time. It can't be Polymaker pre-foamed, doesn't work.
Um like a a 3D Lab print or a ColorFab.
I have I have different uh ways to do it now. So, now I'm doing like 4% 4% 4 and then I do 6% here on this one.
5% on the tail just for more rigidity.
Um and I believe that I did the wings in in uh I have to look back. Um in 5% and the and the control surfaces are 5% and it really provides like you can feel the difference in the in the the rigidness of like the fan holder there.
Um what an easy plane to build, guys.
Seriously.
It's uh literally that that parting seam right there right there is uh is is where you slip the fan in.
You use a little bit of hot glue and then you glue that little that little finger holder back on to support the fan even more. You can get away with it just the three, but you want that bottom on on there to uh to keep the the fan from getting chewed up.
So, anyway guys, hope you like this.
It'll be available on Cults, and thanks for watching.
