Model is really interesting and flies well. Thanks for sharing. But your hearing your wife patiently teaching your child basic arithmetic is even more impressive!
You caught it! Yeah she is the real Wonderwoman!
A flat plate airfoil is inherently stable in pitch. It does not need a vent to produce down wash. For moderate aspect rations of around 4 to 6, the CG can be 1/4 to 1/3 chord. The further forward CG will fly farther and faster. The farther aft CG will descend more slowly. For maximum duration, you want to fly at the attack angle that gives minimum sink. You can use a little dihedral. Fin is not necessary on a glider, might be needed with a prop up front.
I need to try one without the vent. It's a lot more efficient with the vent though.
That was an crazy long flight in your front room. Amazing work as usual. I didn't quite catch the cooking recipe Hope was explaining in the kitchen 😊😊
Yeah the living room footage is terrible but the sight of that thing flying in such a small space was too good to pass up.
@@joshuawfinn you continue to amaze me when you fly in such a confined space full of obstacles 😊😊
Hey man that's pretty cool. When I was little I loved going to the hobby shop, my parents would spoil me with airplane and glider kits to keep me occupied. It's alotta fun. Whenever I would break them I would keep all the parts and would then build a Frankenstein plane made up up of all the diff models. It always made me feel accomplished when one would fly perfect great memories, maybe ill get to relive it when I have kids one day. The duration of that flight is bonkers dude haha cool build
Remarkable indeed.
Such a cool design! Thanks for this! 👍
Neat design…took a moment to see the vertical stab underneath:)
Hilarious how your wife and daughter just totally ignore the fact your flying a plane around the house indoors. And looking at all the model's, trophies paraphernalia you got in the living room I'd say your wife is golden and you better appreciate that 👍
Some of those trophies and models are hers, so yes, she's an absolute unicorn of a wife!
Reminds me of the Peck Stringless Wonder. I have a kit here somewhere
Sorry to ask such an unrelated question, but what is the name of the model that wing on the top rack belongs to at 2:28?? I was recently given one to re-cover and make fly with absolutely no information on it..
That's an Amazoom. It has a similar wing to a Lucky Lindy. Message me with photos of your plane and we can figure out the exact ID, probably using Outerzone for reference.
Nice 😊!
Really a cool plane, flies just great 👍
amazing
The covering should be epic!
It looks a lot like the age-old 'Scott Sky Sled' kite design!
Amazing!
I have an ultra light weight system from a Plantranco Carbon Butterfly that has demised. Going to try to upsize this and fly outdoors. Cover with Clingwrap. Great video as usual and nice to have such a good space to fly indoors.
If you can get some veggie bags, those are lighter and conform better to the airfoil so it'll fly better. This would make a really, really nice rc slow flier. If you set it up with elevons with plenty of travel, it'll be fully aerobatic and still have excellent docile handling.
@@joshuawfinn Thanks for the answer - will try.
that shape IS bonkers! and absolutely cool. enjoyed the living room flight capability.
What is the giant stick you are using (reminding me of South Park Cartman's 'social distancing stick')
cool flight - thanks for sharing with us
Hi.
Why this propeller has such large diameter? Is it for rpm regulation.?( Im newbie)
The cambered foreplane probably does not add anything to this plane. Its trailing edge is not functioning as a trailing edge. The compound airfoil is messing up the airflow. It would be interesting to see what would happen with a perfectly flat square.
Most planks use undercamber in the first half of the airfoil and reflex in the rear third. Works for them. Bigger is it's a full gram overweight and has a very suboptimal prop. And it's floppy so the tips are washing in badly. All stuff that can be fixed but it still wouldn't be competitive. It's fun though and that's all I care about.
Salve . Che tipo di elastico usi. Perché con quelli che ho io , si scaricano subito
Sir u are great 👍
What is the wing covering made of?
I remember reading for some planes its a film mix of cellulose that you have to make yourself. But I don't think that's what's on the square deal is it?
Yeah you're thinking of microfilm...a truly challenging material to use. This plane is covered with 1.4um mylar, which isn't particularly thin but is the perfect weight for this plane.
@@joshuawfinn i remember trying to make some. It was indeed challenging. I could not get it to work. But back then there was no internet where I could ask for advice (1980's)
Another offbeat model on my bucket list. Nice easy flyer.
Does the model turn due to prop torque or is there a rudder / stab offset?
In indoor models with the twisting loads on the motorstick being transmitted into the wing, it's always best to fly to the left. Torque of course pulls the plane naturally to the left, but I did add small amounts of left rudder and left thrust to get the desired turn radius.
@@joshuawfinn Thanks for that piece of trimming info - will keep in mind when I get down to making this model.
Wild! I don't think it has enough wing area😀.
Definitely needs more! Biplane next time?
@@joshuawfinn Double deal?
@@johnharen9921 either that or Big Deal!
Maybe a construction video?
I could, but it would be pretty boring. It's about the simplest indoor plane you can build. Just build it to the original plans in the description and it'll fly, either with a big balsa prop or even a small plastic one.
Looks like its on the wrong side of the drag curve
Yeah, basically!
@@joshuawfinn Interesting to watch by the way. Occasionally you see it get to the other side, it speeds up, which causes a pitch up, then its back on the wrong side again.
Is there any restriction on size of penny plane’s propeller what should be the size am Nishad. From india 🇮🇳I also asked on email plz try to answer 👍
For Limited Pennyplane there are a multitude of restrictions, whereas Open Pennyplane is much less regulated an allows 18" propellers with variable geomentry.
@@joshuawfinn Thank you sir 👍 hope we will meet soon @US
@@innovatorx2112 that would be awesome! Keep an eye on the contest schedules on freeflight.org as you get closer to an opportunity to visit the US. There's also an Indoor Free Flight group on Facebook where you can make connections regarding indoor flying.
@@joshuawfinn sure sir am with my sir Dr. Rajesh Joshi will come there 👍
