Thanx for the favorable comment GD. Actually, when I was flying it and enjoying those banked turns, I suddenly realized that I could fairly easily make an Avro Vulcan style delta using this same construction method. The plan view and tail shape, plus maybe a profile fuselage all seem possible. :¬)
Thanks Chris. I haven't made many planes yet and have discovered that I don't really like them to look 'squared off'. In other words, wings at right angles to the fuselage. Unless the wings are very slender, like my pod and boom glider, I'm not interested in seeing it flying high. Slow fliers, yes, they can be stubby Piper Cub style and hedge hopping or touch and go is quite fun. Plus, one thing that I hate about almost every quick and easy flying wing that I see is that ugly cutout at the back for the prop! Ugh! That was a major part in my decision to choose the 55 degree style delta. I can have the motor at the back, extended slightly, and not have to spoil the cool silhouette. :¬) Actually, I'm just looking at it right now, where it's leaning up against the wall in two halves. (did I mention that it folds along the center?) Although it has inspired me to, one day, make a 1.5mtr span Vulcan silhouette, I'm going to do something with the remains of this one. After it was lightly rained on, having hidden itself in the hedge overnight, ( ruclips.net/video/GRs-hYyIz1w/видео.html ) the artboard is a little warped where it wasn't tape covered. So I'm thinking about cutting back the white areas, which will increase the aspect ratio dramatically. It won't be such a good slow handling craft after that, but I'm interested to see how it looks when flying high over my head! :¬)
Well I did use a cheap motor. But the KF wing is naturally draggy, so it doesn't help on a delta that has so much area. Think of the difference between a Wandering Albatross keaphotography.photoshelter.com/image/I0000PqPn40XAMKc and an Andean Condor www.activewild.com/wp-content/uploads/2018/01/Andean-condor.jpg and you'll know why gliders have slender wings. ;¬)
Thanks Dick. I just used what I had and what I could think up at the time. Also, for your interest, I allowed the second top step to remain open for most of each half span. I actually wedged it open with three slivers of balsa that made a gap double the foam's thickness at it's largest point. I had in mind that all your paper planes will have had the usual open steps. I'm certain that the air behind the step and inside each wing is flowing and eddying, not just behind the step but inside that space. I reckon it's having a right old party in that area. Some time this year I want to try and build another big FK wing after making a few paper ones. I will try to mimic the way the paper opens up at the step and all the way to the back of the leading edge. I have a copy of your excellent book, with no pages missing. So I can copy the shapes of your original designs slavishly if necessary and wot not. :¬P I'm not yet sure what material to use, but I picked up some 3mm insulating foam sheets at the recycling center, so that might do. It's quite tough, but needs taping to prevent cracks. It's all fun!! :¬)
Nice wing.....The UK art boards are very heavy... much(2-3x) heavier than the US $shop boards.. ours are better quality art boards but are poor for modelling... The 5mm paper covered US board has the same weight as uncovered 6mm Depron, so depron or the 5mm hobbyking foam boards will be a better choice to use.. Either foam layered , then with some coloured tape covering gives good strong results.. and will halve the weight of the model.. giving it a better performance..
Thanx John, ( Heh, I'm not checking this channel as often as I should.) The delta was actually only part artboard as the top most and bottom steps were plain foam underlay for wood flooring. The red and yellow colours were packing tape I've found some art board on Ebay www.ebay.co.uk/itm/162088494995 which is 5mm thick and pretty cheap at £28 for ten A1 size sheets AND, and it's a big AND, you can strip the paper off perfectly with a generous application of methylated spirit !!!!!!!!!!!! Yes !!!!!!!!!!!!!!!! I'm uploading a short video of that process even as I type. I have not used Depron as yet, because when I started this malarkey I didn't have access to online shopping for a while and shopped locally for underfloor insulation and artboard. But Screwfix have now stopped the 6mm foam underlay I was buying so I had to have a good look round for something else.
I can't remember exactly what it is. I'm sure it was cheap and it measures about 28mm dia x 30mm long and has a 3mm shaft. I'm pretty sure it's a 1000kv, as I haven't bought anything different for a while. But, as someone else mentioned, it's not really enough for this application. But my planes are getting bigger, so the KVs will obviously have to match by getting lower. :¬)
ChuckPlains Bigger plane lower kV? I'm new to RC planes I've made my first scratch build so iv been researching the web and RUclips for as much info as possible. I live in Wales so when the weather improves I'll go for my first maiden flight but until then I'm still researching.
Great to see someone else getting into it by making their own planes. That's pretty much what I did. Have you used the CG calculator to set the proper balance for the plane? rcplanes.000webhostapp.com/cg_calc.htm I actually first bought what I could afford at my local model shop at the time. But a 750mm span powered glider wasn't a good choice for a total novice. So I then re-started by watching Experimental Airlines on RUclips. I learned a lot from him. Yes a lower KV number for a brushless motor means more torque and at lower revs from the motor too, so a bigger propeller can be used for a bigger aircraft. A higher KV motor will have less torque and will give it's best power at higher revs. Low KV motors are generally bigger, particularly in diameter. Oh, and big or small, high or low KV, brushless motors generally give more power than similar sized brushed. And as with all motor and prop combinations you need to use an ESC (electronic speed controller)with suitable capabilities. Specifically the max Amps of the ESC needs to be considered. So when you buy a motor, prop and ESC you need to balance the three, reasonably well, against the weight of the plane. One big plus of brushless motors is that you can run them at different voltages. Brushed motors are not good with the wrong voltage. So whether you're using Lipo, NIMH or even the good old Nicad batteries, you can usually choose 2 cell 3 cell 4 cell etc, depending on the motor and ESC specifications . The smallest planes often use single cell Lipos. I have to confess that I've got by trial and error and research. Ironically though, buying a plane gives you a good idea about what works together, size wise. I eventually bought a Bixler from Hobbyking and learned, eventually, to fly with it over two years. But even the older version of that is around £70 now. 'tis a really good trainer though. But there is also plenty of friendly help available on the forums such as rcgroups.com , modelflying.co.uk and so on . And there are a few motor/prop "calculators" around too, though I actually found them rather complex and so fell back on the trial and error malarkey.
I hear you, but I mostly fly gliders and require my Lipos to get used across different aircraft. So I'm more likely to go for a different prop to increase thrust. Hmm, 10x7 3 blade folder?
Ah, no, no plans. I just thought about a paper dart, thought about other foam deltas I'd seen online and especially on Experimental Airlines on YT ruclips.net/video/TfNiZX1ukyM/видео.htmlsi=FTCv476wjna6O6Vx And just folded the foam, added an extra layer etc, added the motor, found the c of g with the battery position. Then I threw it away, but it came back! Eventually. 😁I havent flown anything in the last 5 years though.

First flight on homemade planes are always the best, LOL
have fun !!!!
Smooth flyer, great job!
That is about the speed I think I could cope with. Great flight, nice and gentle.

ChuckPlains I was pleased to see I am not the only person how seems to attract dog walkers :)
Oh they're pretty regular around there, it's on the edge of Dartmoor.
ChuckPlains Lovely place to fly in the warmer weather, not so much fun in the mist :)
That's a Sleek-Sweet looking Wing Chuck!

Looks like it flies well, but just a bit low on power. I seem to always have that problem when I build this type of plane.

Sure thing!
"ULLO SAUSAGE" made my day :P Nice work man! Even if it's a bit underpowered it responds to input really well.
Heh, thanx. It's just a shame that I didn't respond to where I was in relation to the ground a couple of days later! ROFL! :¬P
Like it!
Flights nice. Nice maiden.
Thanks Nelson.
Very nice build. Gentile flyer and easy to control. Great build. Dick. The K in KF

A bigger motor, some reflex on the elevons, and smaller fins and it will fly great.
Reflex on a flat plate is up elevator.

Love it ! It has very nice flight characteristics, I could tell from the first throw it was a goody 😊. Did you have plans for this build?
