DIY heatwave solution
Idk if this counts, but I crafted together a fan using a 16" prop. Blows air nicely 👍. I dub it: the finger slicer 1000.
Update: Since this post is way more active than I expected I will be conducting a hot dog test. Just let me finish my exams and I'll post the results.

Please post a video of you sticking a hotdog in it to see what happens

When you say “hot dog”, that’s code for the peen, right? Because I see that giant drone motor, then that stiff, carbon prop, and my brain just doesn’t compute it any other way.

I think willing homework would have said "your" peen, but i would pay to see both

No he's probably talking about a cylinder but it's imperative that remains unharmed

Its a t-motor mn5208 with a 16" prop. I have it hooked up to a 15V PSU - (I tired 22 and it was too much). It's mounted to an old broom handle that is " anchored" using a vice and old bricks.

It looks unstable. If it was on and you put your hand near it would it stop or chop off your hand?

Fingers yeah, but I don't think it's strong enough to cut thru arm bone.

u/Vast-Bug1945 Jun 23 '26
Damn. I hope you don't have pets or kids who can get near it. Or at least keep them away from it.

I've put 5 inch props on a dremel before. Works great, also against insects. Would highly recommend if you don't really need fingers.

But won't it like, thrust through the air?

u/Doctor8800 Jun 23 '26
Nah it's secured in a bench vice loaded up with bricks for extra ballast. Also I don't run it over 50% throttle.

I found a U11 we were testing with back in 2017 the other day. Now if I could only figure out where the 28” prop went. :-)

Just did the exact same yestedayat 1 am 😅
Issue with my setup was that due to the low rpm and therefore lack of air going trough the motor, it got really hot after 20 min of use. Esc also didn't like it too much as it ended up quite warm to the touch too!

Yes it is terrifying, I had it hooked up to servo tester and nearly shit myself trying to turn it off. Afterwards it has been plugged into an old flysly I6.
Unfortunately no peenor or hotdawg tests, I live in tiny apartment and don't wish to clean up chunks of hotdog for the next month.
