Testing the American Kestrel 12 (Improved changes?)

- This is a laser-cut model and after making a few changes to the original design, I wanted to see if this is flying better.
Build Kits and Plans are available!
nighthawkglide...
This was flying very well this evening! I should have only adjusted one configuration at a time, but I got very eager to try several things.
1) It has less dihedral on the main center wing joint. I was hoping to change the lift vector more upwards.
2) The wing was moved back a 1/8th inch. It seemed a bit too loopy, so by moving the wing back I was hoping to have a straighter launch.
3) I glued the vertical stabilizer to the side of the fuselage (instead of on the bottom of the fuselage.
All in all, I think the results were promising! Which makes me happy! ;-)
Brad and Bruce are brothers-- just having some fun building, sharing, and flying various things-- including experimental catapult balsa gliders to free background music because they are cheap! (but, the music is good... kudos to the music artists!)

Enjoy flight and enjoy life!

1:35 Yes, I think it too! :) Very nice shoots and flies. I congrat to your modifies!
Thanks, goldenfish! 😊
Lovely video and that music really helps the ambience 😊
Thanks, Grandad! Yeah... I enjoy some accompanying music when I watch these things glide so peacefully through the air. 😊 Glad you enjoyed it, too!
Very long flight times! I like it very much! Your gliders are very thin and easy weight. Perfect!
Flies great! Seems to have a sightly high sink rate. Maybe built it a bit lighter, like 5 grams. Also i think you could go even a bit lower on the dihedral. That would also help improve the glide a bit. Nice model! I’m a fan. :)
fantastic glider, love micro gliders well done :)
Thanks! They are fun! 😊
Good to see you here.
Love it somebody that does flight times. In. College we would go for glide distance. We had about 25 feet up from the dorm.
nice plane
Great design guys! That's so tunable! buying a few! :D
Thanks, John! 😊
Cool! I love your gliders!
We’re happy if you’re happy! 😀
Nighthawk Gliders and I’m happy when you make me happy!
Flies Great!!!✈☝☁🍃))))
Flies nicely. Lighten it up a bit and use separate flaps and you could probably have a competitive design for Elastic Launched Glider.
Hmm. 🤔
estoy necesitando urgente un par de estos modelos
absolutamente! 😊
@@NighthawkGliders where I buy the plans?
Visit www.nighthawkgliders.com. On home page, sign up for our news and announcements. When plans are available, we’ll email you. Thanks!
Looks really good!
When will it be available?
Thanks! We don’t have release date yet, but if you go to NighthawkGliders.com and sign up for our Newsletter, you will be notified ahead of everyone else! 😀
would suggest a little less dihedral to avoid what appears to be a little dutch roll in flight. but a beautiful little glider with a surprising performance. John Gray [New Zealand]
Yeah. For this test, I built this glider with less dihedral than normal. I may even need to lessen it some more. We’ll see. 🤔. Thanks for commenting!
Could You show how to trimm/adjust Your gliders for perfect fly? How to fix usual problems after assembly kit from Your store...
A reasonable request... we’ll give this some thought. Thanks for the suggestion! If you purchased a glider, we appreciate that! 😊
Awesome!!
I know, right? 😜
Why does it wobble?
Nice gliding.
Myplane is about 2.9~3.5g
Thanks! Wow, your glider is super light!
Seems 30 second flites consistently :)
What is the notch in the wing ????
What is its purpose ???
TNX :)
Well, technically, if wing is sanded thin enough, you can gently curve the trailing edge of the wings down to slow down its gliding speed and increase the wings lift performance. But, I think it’s mostly for looks! 😜
Do you have any tips and/or links to videos for long flying indoor gliders?
Good question... especially if you are doing this for competition such as in Science Olympiad (for example.) I'd say some of the key obstacles to indoor flight is (1) Low ceiling height and obstacles, (2) Air conditioning/heating left on, and (3) hardwood/cement floors... So, you'll need to have a super-lightweight glider that has a reasonably large wing area that is close to the minimum weight required by your rules. You want to launch it as close to the ceiling as possible w/o hitting rafters, lights, basketball hoops, etc. Avoid air drafts because that can make your glider stall dramatically (and even crash!) Normally in competition, they turn them off, but when you are practicing, you may not get such luxury of turning these systems off. Hard floors can be a challenge-- especially if you are testing gliders and they are not trimmed yet... they can stall, flip, or roll and hit the ground hard and break. If you have a calm day, launch your gliders outside over grass to get them initially trimmed. When indoors, launch them gently and lightly and trim them as you progress to higher and higher altitude. The main keys to good flight time are high altitude on launch, successful and quick transition into a glide, and a good glide ratio. Always launch your glider with a starting roll and trim your rudder to continue its glide in the same direction. And I repeat-- avoid the obstacles... if it hits something, the flight is over! So, change your launch location and/or direction! And finally, build lots of gliders and practice, practice, practice! I hope that helps! Good luck!
@@NighthawkGliders That was very helpful, thanks!
couple 30-31 second flights... NICE!
has me wondering if the egg carton top idea cant be modded for band launching.
its sure not that I don't love balsa, its the cheap+available+recycled things everyone has!
Thanks! Still holding on to your egg carton plan... for I have a few cartons stacked on my shelf. Someday, I hope to get around to tinkering around with that idea to see how it flies. 😊
kept really light, for indoor tossing it'll surprise ya. thinking it'd need about a 3" spar (skewer slit to half round) to bridge the big dimple so it doesn't fold up with a band launch. a hook up front with thread and CA, moving the tail feathers forward a little for a bit of skewer to pull back... all easy enough to tinker with.
recently watched a couple foam board chuck glider videos, it's generally too thick for small stuff but some of the foam board DLG (discus launch RC glider) were really impressive!
Hey are you guys OK, you have been quite lately.
Yup, Grandad... we are overdue for a video! 😜 Just been busy with other things, unfortunately. Thanks for inquiring about us!
When will this plane be available???
Working on it! 😊
Cool!!! :D
We appreciate your comment, Antonio! Thanks! 😊. Hoping all is going well for you in Brazil?
Yes my friend, It's all fine by here!! Thanks!! :D
This is a laser cut model ???
From where ???
I look on your website but see nothing
This sort of looks like a SuperSweep
A glider that would be awful hard to beat
Yeah, we have a laser cutter. We’ve been kitting them, but only made them available locally. Online Store coming soon as we have some hurdles to overcome. Sign up to our newsletter on our website NighthawkGliders.com and you’ll get first notification (and dibs) when store opens! 👍😀
ขอแบบแปลนหน่อยได้ไหม
ขออภัยเราไม่มีแผน ขอขอบคุณสำหรับความอดทนของคุณ!
I like to trim my gliders to the point it they just almost barely barely barely threatens a stall dip !
But that is just me :)
That’s cool. What type of gliders do you fly and do you fly them indoors or outdoors?
@@NighthawkGliders Hello :)
I fly a almost a 12 inch Sandpiper :)
I used some of the dimensions of your sandpiper but do not cut the sweepback on the leading edge , also I use a horizontal elevator , with the rudder in front glued to the stick !
I do spend time when I build !
I am so much a stickler for accuracy
I have trouble getting much done !
I posted on Hip Pocket aerodynamics earlier ! I flew in the park today and had one really good flite :) tnx fer reply :)
Nici flight mr breth y see thes model Refit Wit motor rubert power porpeler obert the fucelach in that center of the qlider fo corse experimetal 🤔
Interesting thought. Hmm... 🤔
Wel y finich th see une videos of mr .joshua up oade to deis wit rokect proutioc tivaices rejetet so is vrei intresting maiy miting the chanel wit haven..?
Well, when i play with it, trust me, i can drop from 80 to 75 kg in one day lol
Better than spending time in a gym! 😊
@@NighthawkGlidersyup, lol
Love it somebody that does flight times. In. College we would go for glide distance. We had about 25 feet up from the dorm.
