[Brad] All the way to the wall. Not bad! Seems to work pretty well.
But is it consistent?

Hey guys! Welcome to Nighthawk Gliders. I'm Brad. Today I'd like to
demonstrate this - [Other Brad} Wow this looks cool. Can i play with it? What is it?
[Brad] I was just about to explain this to our audience. [Other Brad] We have an audience?
[Brad] Sure, our good friends on the internet they subscribe to our channel and watch our videos.
Ok, Take it easy now, take it easy. You know what there's a Rubik's cube over
there why don't you go play with that for a little while and come back to this later.
Sorry guys, my alter ego gets a little bit rambunctious.
So what we have here is a homemade glider launcher built out of some basic items found around the house.
The idea is not to launch this glider at a super high rate but instead
launch it at its gliding rate I wanted to see if I can build a consistent
launcher in which I can actually measure the gliders rate of descent so
in other words how far it will fly forward versus how far it drops so this
particular glide rate is essentially equivalent to a lift drag ratio as well
so it might give me a bit more information about the characteristics of
my glider. The principle is based on a class-3 lever and the idea is I will
pull this back and as it goes forward these dowel rods will hit this wedge
open up and release the glider forward. Pretty much like this...
All the way to the wall. Not bad! Seems to work pretty well but is it consistent?
Let's do some slow-mo tests and check out exactly how well it behaves.
[Other Brad] Hey, this is hard. Can you help me solve this?
[Brad] Uh how about later let's launch some gliders right now.
[Other Brad] Yeah, ok.

Well, that was fun. We've got a lot of different launches from a lot of
different angles. Got some slow-mo and I was quite pleased with how the
launcher performed. It was a little sketchy at the beginning and I had to
adjust a few things like this little bit of tension right here and the
wedge placement. Once I had it fine-tuned, as you can see, it flew quite nicely and
it also showed the left turn that's pretty much how this works with the tail tilt.
Thanks guys until next time we'll catch you later!
