Nice looking plane and its always great when a scratch built plane flies well - and this one certainly does. For the fear of the prop striking the ground: have the break "on" (as you do), but mainly, NEVER have any amount of throttle "on" when you land - then forget about the rest... It is highly unlikely the prop will get damaged on landing if you do the above 2 things - seriously! For the pitch up under throttle: try changing the angle of the motor by placing washers under the the top 2 motor mount screws - may sort you out!
To help protect the prop, what about using wire skids? Basically, it’s bending two wires, placed on both sides of the length of the body, that lifts the tail of the plane up so that they don’t land on the prop. As you come in for a landing, the wires are acting like sled landing gears. Great looking plane and great flying.
I am really enjoying your RC modeling videos. I've been scratch building my own designs for over 25yrs and I really appreciate your attention to details in a time when most rc pilots are flying a poorly engineered Chinese foamy or a terribly inefficient foam board contraption. No offense to those folks, but modeling seems to be becoming a lost art. Damn, am I an old fogey already? Cheers
Very cool :D the only issue with that orange small cell insulation type polystyrene is it gets dings and scratches very easily, other than that though its quite easy to carve/sand to create nice smooth surfaces for wings and fuselages. Excellent job flying as well, looks nice and smooth.
Nice! I just started experimenting with a micro A-tail a couple days ago. Bruce Simpson keeps posting videos of his little micro FPV plane, and I decided I needed one too. Never had an A-tail plane, and decided to give it a try. So far it glides well, but no electronics yet.
You did really good. Your so called worst by you and like 20 steps above some that I see call their planes good. Thumbs up. Give it a good bright under color so that it can be seen from a distance. Something like orange as its negative to blue and the sky is blue most days.
Looks like the cows came over to visit. Excellent result! Must go back to see how you have managed this if I have time. I have several builds as yet un-maidened, all works done during winter months. And some are quite ambitious for a noob in conventional fixed wing flight....just a hack with visions of grandeur.
Hi I first saw this plane in 1968-69 and it was built by a fellow named Ray Longacre. Just a thought tho the mixing for the inverted -V- tail was acomplished with three servos and a sliding rack.(no computer radios). It was a great flyer. What more did we need pusher engine ,inverted -V- tail four chanels high tec fiberglass construction . Life was great... Oh and no retracts... Rohm Air and Spring Air wern't around yet. Thanks Jim Love.
Beautyful plane! I am not into model air planes, so I don't know if these "strange types" (diagonal tail, prop in the back,...) are very common, but most of your planes remind me at the Crimson Skies games, where you could build you own air planes for air fights ;) I love you can see the plane in the third person with the runcam, but a little servo and a cutout in the tail wing to tilt the camera to the ground would be awesome.
Fantastic video , I enjoy these videos a lot . A few thoughts : that plane is supoosed to be extremely efficient given that the transition between the wing and the fusolage is extremely smooth , that decreases interference drag A LOT. The booms are definetely a bit too flexy , but other than that , it looks good . Might need some flat spars inbedded into the outer wings to help with flexing
Hi Nice plane, I also experimented that kind of tail. Pitch down at high power is due to booms bending. You can add a second boom on each side on wing upper side align 45° inward like the tail.
Excellent. Maybe getting the CG better placed will help with the trim setting. i.e. if it pitches up on power-on then it's nose heavy. If it tip stalls to the left, maybe that wing is a little heavier. Did you do any lateral balance, most model flyers do not. Other than that, I love it, great stuff.
Looks good, I like the fuselage and wing design! I was expecting it to pitch up more on rudder input. Maybe the large stabilizer surface dampens the pitch. Would be interesting to see if you could get into a full bank with the rudder alone. Alot of interesting possiblities with the design like adding differential to the V-tail elevators/rudders.
The angle of the tail planes are pretty much 45 degrees (90 degrees to each other that is) so I think rudder should be neutral in pitch. It banks a lot more than I had expected from just rudder, so yes banking seems pretty easy.
How about thinking to put a foldable prop on this bird? It would let you stop the motor spinning and you wouldn't have any doubts for bending the prop while landing. 😉 Btw: Nice job done. 👍😃
Damn I love your projects Chris... That thing flies great! It's fun to hear you get excited about it while flying it ya know? Love the glide *whoosh*. AND... The best thing about that plane? NO LANDING GEAR. LOL! What's next? Flight controller and FPV?
Re: flite test style + tail weight : 3mm foamboard works really well for most applications with span up to 400mm IMHO. You can save 50% of your tail weight between that and less hot glue like you said. 😊 I love FT but I find the smaller designs are way heavier than I'd like when made of 5mm board.
How much it weights and what is the motor ESC combination...??? Yeah... when you mentioned the weight of the plane... and saw that little tiny motor! I realize you need a more robust power plant.... I'm in total unbelieve of how good that airframe is.. and how little take it to glide... but it is clear that you need a bit more of power , Now let us be honest!! This plane remind me of the plank style of pilon plane!! "Very low resistance & High speed" Finally just by personal experience "About the battery...& weak cell" I use to buy the 6S 8000mAh.. (It only took once for a cell to die before I started to buy the 2S packs... in that way if one die is much easier to just trow the one with the bad cell and replace. So incredibly nice video sir!! thanks for posting it..
Wow! Nice piece of work! Flies good, looks good... Here's a few notes that may/may not prove helpful for tweaks etc. - Yes, weight is deceptive... I often hold a plane in my hand and think "wowww it weighs so much" only to find it's unfeasibly floaty once I get it in the air. From the way this handles (especially how relatively hot it lands) I think it's at the slightly higher region of the wing-loading bell curve, but far from a "lead sled" - it hand-launches too well for that. (Keen to know what its wing area is, if you get a chance to work that out.) - Although the boom flex was impressively low for 6mm, I think you might have an easier time mounting your camera on the center body - the wobble should be gone entirely and you'll have a more permissive range of battery sizes to hit your desired CG. Just making a little foam fairing to blend the camera body's trailing edge into the fuselage should cut its drag right down, too. - RE: the wings being friction-fit: I've had nothing but good experiences with that myself. There's no in-flight loading that pulls outward down the wing's longitudinal axis, and you'd need some pretty brutal oscillations to vibrate them loose. If you're worried, just slap a bit of tape on the top of the wing/fuselage join point, with a little fold-over at the tip so it's easy to peel off when you want to remove the wings for transport etc. Furthermore, I've found that friction-fit plug-in wings save themselves beautifully in a mild-to-moderate tip crash; energy that would have dented up the wing tip severely just goes into (partially or fully) unplugging the whole wing. Intentional failure points may not work in full-scale, but at model-scale we can really make the most of them! :) - Trims: For ease in future, I'd say find the throttle setting at which the plane can just comfortably sustain level flight, and do your trims at that throttle. Climbing on higher throttle (or dipping on lower) is entirely normal behaviour and generally what a full-scale plane will do - the way I've seen pilot manuals explain it is, you trim for a given *angle of attack*, not a given climb/dive profile. What the plane actually does with your trim setting will vary with airspeed. That said, model flyers usually prefer to tweak a plane until it stays dead level with throttle changes, and there's absolutely nothing wrong with that - just don't take climb-with-throttle as evidence that you've made a build mistake. :) Anyways, enough gasbagging from me... this is a gorgeous aircraft, flies like one, and it's really cool to see the results of a build with that stiff yellow foam stock (I've just inherited some myself and wasn't sure how it stacked up to the softer foams I normally use.) Congrats on a successful build, hope you get some sweet FPV flights out of it!
It'd be cool to have the foam cutting templates sized so the foam would be the right shape straight from being cut. Of course you'd need more templates to do it that way so....
Just discovered your channel... and already subbed :o) This is some work! Very impressive... and congrats to your successful maiden. Maidens are always nerve-racking :o)
WOW Chris! That's an awesome plane! Well done! I like the look of the plane and it seems to be able to glide for days. Too cool! You said that you have 6mm carbon tubes as rear booms and you think they be a bit flexy. I wonder if you were to double them up, would that help? Anyway....really cool plane man!!!
I was just thinking about what happened to iforce2d and suddenly notification appeared. In my country there is a saying that if u think about someone and he/she suddenly appear then he/she is a good person. This must be the internet equivalent of real life saying.
Actually that first landing was going downhill, about a 5 degree slope so it just made the glide look better. I might experiment with flaps if I put a flight controller on later.
Re: left wing dip on stall : the prop exerts a torque on the plane even when windmilling... I dunno which way your prop turns but if it's going clockwise seen from behind.. Voilà
Carries momentum quite well in the glide which I figure is great with the efficiency goal, but seems like it may be worth trying a flaperon or spoileron mix that toggles on to help with bleeding off speed and getting it to not float so much (ground effect?) on landing. I would think that would be something that should be quick to try out if your controller setup allows you to program it. And do you think the stalling to one side is caused by something off by a hair on one side, or is it just aero drag given how that camera setup was done? If it's consistent and predictable, and powered flight is good, probably not worth worrying about though.
I'm not really the person to ask. One thing I noticed pretty quickly is it's worthwhile getting the mix proportions right, don't just think close enough will do. Use a scale to weigh each part as you pour it into the cup.
Nice build! I plan on scratch building a fixed wing FPV platform. It will be a conventional built up or combination of composite and built up airframe. The airframe will be similar to the Skyhunter or Anaconda or a twin tractor like the Senior Telemaster Twin but with a NACA 2412 airfoil. What airfoil are you using on your scratch built Skyhunter? Thanks...
NACA 3310 ... ish airfoiltools.com/airfoil/naca4digit?MNaca4DigitForm%5Bcamber%5D=2.5&MNaca4DigitForm%5Bposition%5D=32&MNaca4DigitForm%5Bthick%5D=10&MNaca4DigitForm%5BnumPoints%5D=81&MNaca4DigitForm%5BcosSpace%5D=0&MNaca4DigitForm%5BcosSpace%5D=1&MNaca4DigitForm%5BcloseTe%5D=0&yt0=Plot
@@iforce2d Thanks for the reply. You said NACA 3310...ish but linked to 2310. I could not find a 3310 in the NACA database but was able to create that airfoil. Do you know what airfoil is on the is on the Skyhunter or maybe even the My Twin Dream? I hate that I over think everything but not knowing much about reynolds numbers and only being familiar with lighter wing loading aircraft instead of heavily loaded long range FPV craft I'm really trying to find the best airfoil to use.
I'm crazy about the look and flies really good too. I think it flew better after shortening the tail or was it changing the expos? I'd be interested to see how it does with a stiffer tail. Another great build, thanks for sharing!
I think it might have been a bit of both. The expo definitely made me feel more in control, but there also seemed to be less bad tendencies in need of controlling.
I really love the look of this bird. Would you at all be willing to share your 3d files for this project? I would very much be interested in making this a scaled down 3d prontable project, a la 3d lab print! Love your channel!
Yeah I was thinking that, but decided to go with the mini talon sizing. But watching the video now, it's amazing how much it can roll with barely any visible movement of the ailerons.
@@iforce2d ..the thing is i only ever flew slow airplanes so I needed large ailerons almost always... But the one youve made is relatively fast. So smaller ailerons are doing it for you...
That's a very pretty plane and seems to fly well. Is it just an optical illusion caused by the intervening prop or does the starboard wing move slightly at the root in flight?
@@iforce2d It may just be distortion but in the clearest examples it seems to move in and out laterally at 16:33 and again at about 17:56 on. it's not a big movement (if it is a movement) I played those two sections back @ 0.5 speed.
3536 1250kv, 9x6. I forgot that I was impatient when ordering and the 950kv was not in stock, so I got 1250kv. That would explain why it was a bit hot and was doing level flight at under half throttle.... I might try an 8 inch prop and see if it still has enough oomph.
@@iforce2d Thanks Chris. I also use the 3536 as usually running a 10x6 Folder at 35A. For pusher I use the usual limiting to stop the blades crossing over. The 9x6 should be around 25A. The motor has served me quite well apart from the odd bearing failure. The combination I seem to have settled on is ~1000Kv 10x6 3S.
I really should listen to the dialogue track carefully;). You may have lost a bearing with the noise. I use Motocalc (quite old) which predicts 38C 1700gm of thrust running 9x6 on 4S. The 8x6 is slightly hotter at 40C with 1200gm of thrust.
i have a method for folding foamboard with paper that i use for kf airfoils i make 5 shallow 2.5mm cuts in the foam just deep enough to cut through the paper and into the foam a tiny bit the middle being on the line im folding over then i use any rounded plastic object to compress the foam in that whole 10mm thick area then put tape along the other side so the paper on the leading edge doesnt tear then just fold it over and it makes a perfect consistent fold every time or you can do just 3 cuts 2.5mm apart for a less then 90 degree fold
I like the way it looks in the air. Looking graceful is often the sign a good shape.
Nice looking plane and its always great when a scratch built plane flies well - and this one certainly does.

Does it look "right" in the air is my initial check, and BOY OH BOY does it ever! Rock solid. She's a goodun.
Nice looking plane, flys nice and that sliding tail assembly for achieving cg is brilliant, nice job iforce2d, well done.
Really love the way you are trying to build your planes experimenting with different materials. Please keep it up. Thanks!

Well done. It's a good looking plane and it would be excellent for FPV missions. I'm a big fan of DIY builds
Yeah I wasn't thinking doing much more with it, but it does fly nicely. We'll see, it might even get a flight controller one day :)
FC/missions and a mini talon efficiency comparison would be very interesting me thinks 🛫
Dammit that's a good looking airframe and she flies like a dream. Bloody good job Mate.
Really awesome! Such a nice plane with really nice stall characteristics. What's left now is to find an easier way to make it.😁
Yeah that's for sure :)

don't you want to put some fpv cam and lower frequency long range system on it ? You got some nice area there
Yes I'll probably be doing that :)
Mate don't you think the ailerons need to be larger...
Nevermind it flies great
Yeah I was thinking that, but decided to go with the mini talon sizing. But watching the video now, it's amazing how much it can roll with barely any visible movement of the ailerons.
@@iforce2d ..the thing is i only ever flew slow airplanes so I needed large ailerons almost always...
But the one youve made is relatively fast. So smaller ailerons are doing it for you...
Fold-able prop.
Yes naturally that was my first thought, but the only folding props I have vibrate like crazy, and hard to find a hub with a 8mm diameter hole.
That's a very pretty plane and seems to fly well.
Is it just an optical illusion caused by the intervening prop or does the starboard wing move slightly at the root in flight?
Can't say I had noticed. At any point in the video in particular?
@@iforce2d It may just be distortion but in the clearest examples it seems to move in and out laterally at 16:33 and again at about 17:56 on. it's not a big movement (if it is a movement) I played those two sections back @ 0.5 speed.
@@didactylos4diddy474 hmm... still can't see it. I wonder if it's reflections on the packing tape.
@@iforce2d Could be I guess
Good result. What motor and prop did you end up using?
3536 1250kv, 9x6. I forgot that I was impatient when ordering and the 950kv was not in stock, so I got 1250kv. That would explain why it was a bit hot and was doing level flight at under half throttle.... I might try an 8 inch prop and see if it still has enough oomph.
@@iforce2d Thanks Chris. I also use the 3536 as usually running a 10x6 Folder at 35A. For pusher I use the usual limiting to stop the blades crossing over. The 9x6 should be around 25A. The motor has served me quite well apart from the odd bearing failure. The combination I seem to have settled on is ~1000Kv 10x6 3S.
I really should listen to the dialogue track carefully;). You may have lost a bearing with the noise. I use Motocalc (quite old) which predicts 38C 1700gm of thrust running 9x6 on 4S. The 8x6 is slightly hotter at 40C with 1200gm of thrust.
Would it pitch up coz ur motor is under the wing?
It mainly depends if the thrust line of the motor is above or below the CG.
Sell me one of those.
follow the way flight test do their foam folds
What's the wingspan and stall speed?
Wingspan is about 1450mm. If I put a flight controller on later I will try to determine the stall speed.
Is your motor balanced?
salutnge of location and farmer ? 😃
may need flaps
i have a method for folding foamboard with paper that i use for kf airfoils
i make 5 shallow 2.5mm cuts in the foam just deep enough to cut through the paper and into the foam a tiny bit
the middle being on the line im folding over
then i use any rounded plastic object to compress the foam in that whole 10mm thick area then put tape along the other side so the paper on the leading edge doesnt tear
then just fold it over and it makes a perfect consistent fold every time
or you can do just 3 cuts 2.5mm apart for a less then 90 degree fold
i have the same radio! £36 isnt it great
do you have the open sauce firmware?
