That wont win any competition flying trophies and will never even show in a beauty contest, but it's probably a blast to fly and really affordable to replace... well done, I love it.
yep! you're correct. I've flown wings with practically no vertical stabilizers, the only issue is at takeoff there isn't enough forward airspeed to guarantee proper yaw control. Though once you're at speed, any yawing is pretty much damped purely by the windward wing half creating more drag (and lift) than the other side.
Flight controller? We don't need no stinking flight controller! What a GREAT explanation and demonstration of a self-stabilizing airfoil. I also loved your deep dive on stabilizer angle which ends with a very honest justification: because it's cool!
I've never built anything out of foam but have been trying to find a tractor prop wing exactly like yours for ages! Specifically one that is portable, really manoeuvrable and quiet! Do you have any more tips or build guides that might be useful, please?
I don't have a specific build guide, but having built a ton of planks over the years here are a few general rules: 1. don't make the airfoil too thick. if possible choose a flying wing airfoil and not a flatbottom. 2. cg inline w thrust, close as possible to the mean chord line 3. tend towards nose heavy -- tail heavy wings are not fun 4. try not to have too much vertical fuselage surface area ahead of the wing, this will impact turning and yaw in weird ways 5. tune your throws so that if you use elevons, aileron authority should be less than elevator, otherwise your rolls will be super twitchy 6. for small planes such as these (
@@prestonsterling7454 Thank you! That's really helpful - thanks for taking the time to reply. I've literally never built a single foam scratchbuild so I'm out of my depth at the moment - but there's one way to learn, I guess! I need to find a basic guide for a simple foam airfoil and then just experiment, like you say. Thanks again - really appreciate the help.
Hey Preston its me who made the plank and had mistakes in it I uploaded a RUclips video and unlisted it as you wanted Can you tell me where can I privately send you the video link
Hey Preston i’m Zidane from india doing my a levels currently and i have been inspired by rc planes and fluid dynamics So naturally i decided to make rc models and few of them were very successful but few weren’t I have gotten intrigued by your rc plank flyer model and wanted to build my own and replicated exactly what you did but my model seems to have major flaw If i could just have you look at the model and tell me whats wrong ,I think that would help me a whole lot Thank you Preston I will send you the picture and footages on instagram ( couldn’t find you on Facebook)
hey! I'm reluctant to share my personal info with people on the internet. If you make a youtube video (you can unlist it) I would be more than happy to provide comments

that's the point.
Such a simple plank but so stable that while took off it seems to be like having a proper flight stabilizer integrated inside.
Now that’s cool!!! I’m just starting to get into the foam board builds
Looks like good fun, must build something similar
Please what is the weight in gram
i'm sorry, this airplane hasn't existed for about four years now. I forget.
Wow that flies amazing. And thanks for all the explanations!
36 months ago 😢
Thank you for playing decent music
What is the wingspan and rootchord of wing?
I forget. you are best off eyeballing off this video.
Beautiful!
I freaking love this video
Brother, will the motor have to be tilted in this plane also to cancel the opposite torque of the motor?
Yes
I have built and flown several of them using the same flying wing info. They really don't need the vertical stabilizers.

thank you!
flies great!
Amazing !
Awesome build!
thanks for helping me film haha
Kindly please, do you have dimensions and build instructions?
Unfortunately I do not.
Cool. I love flying planks - they act so bird like. What is the WCL?

super mon gars c magique bravo a vous
Wow ! This flies Awesome ! What's the actual dimensions ?
wing area is approx 15x30" if I remember correctly. Built from 1 sheet of Dollar Tree foam
@@prestonsterling7454 Thanks Bro
it's a funny flying sheet of foam lol

Can you tell me where can I privately send you the video link
Nice
И летает гораздо медленнее обычного ЛК.
Fast nyoom~
Don’t die
thanks. I haven't yet

Hey preston Where do i send you the link privately?
