This Glider Crashed today, haven't been able to find yet it but I expect it to be destroyed.
TheRattleSnake3145 noooo it was so beautiful I am trying to make my own and is was looking again for som ideas
TheRattleSnake3145 have u already found it?
Floris Heuperman will have a look again tomorrow, it landed in very thick Mangrove trees and the tide was in at the time. I was walking in waist deep water muddy water in mangroves that thick it was about 5 -10 meters visability at points. Looked for about 1 hr but figured it landed in water so not much chance of finding anything usable.
I’m sorry buddy, what happened?
I think some kind of turbulence causing a tip stall, when I pulled out of it the wings couldn't handle the g's and one broke. Looked for it for around 6 hrs total and after the 3rd attempt (2 weeks later) it was found. much less damage than I expected. The wings have been strengthened and it has now been fully repaired. recovering has almost been finished, then I just need to reinstall new electronics as it was out in the weather for 2 weeks and I don't trust it even if it seems to be working fine.
I'm not a modeller but I find this video so inspiring. What a beautiful looking plane too, I was shocked to see your "I expect it to be destroyed" and that it ended up lost in a swamp and so glad to see that it survived! I look forward to seeing more footage of it. Thanks very much.
Awesome built! Thank you for the idea of wing part joiner with Motor and ESC connectors!
@@goldenfish77 don't forget , you still need to tape the wings on or use different method to secure the wings. The connectors are just to locate the wings.

Thanks for the warning too! I hope you fly with this beautiful glider!
dude, that is fruckin awesome... brings back memories of building with my dad as a kid... that covering job is cool... looks like a bunch of solar panels
thanks!
mate that is frankly an awesome bit of workmanship, totally impressed ..
Great build tnx robin
Impressionant! Little wing load and great gliding capacity---Perfect Finish
What a glider !!! great to see old school building !! warms me heart !!!
Excellent craftsmanship. Floats perfectly without the motor.
Jason Jackson thanks for your kind words.
I used to build models with my dad years ago and want to make one now. This is the best tutorial I have ever seen on RUclips and beautiful model
That's a beautiful build. Thanks for sharing. The copper color and the blue osmokote are a great color scheme.
Thanks!
Very nice build my friend. Looks like a hell of a floater.
thanks, and it is!
thanks, and it is!
wow. great video edit and gorgeous plane. loved the maiden toss. perfection.
lots of satisfaction when you see something you create working as you intended.
Wow!! beautiful job and a fantastic finish.
You obviously took your time and care during the build and it shows.
Well done. 👍
thanks!
Wow what an excellent flying plane. Great build. That thing friggin floats!
Mate, very nice. Maybe I don't have to buy a Gentle Lady or Bird of Time, just make my own.
At our club, Logan, the guys kill their own Radians. Three major crashes in the past two weeks and two fly away's in the past six weeks. Yikes ....
Great to see you got her back. Keep up the great work.
Excellent!! It always amazes me when I come across a channel like this after so many years of balsa search history have gone by. No YT, I don’t wanna see this guy just killin’ it in the wind, I’d rather you suggest Dr. Pimple Popper. Subbed and added to the “Why the hell am I unsubscribed?” Checklist.
Oh my god that thing is so stable unbelievable, it beats fluid drag.
damn mate, that was a beauty, test throw was stunning, and a nice build vid.
Great share, thanks. Not everything needs to be an ARF, nice replication of characteristics. Wing looks bigger than 2m, though.
What a wonderful machine. A thing of beauty.
Dude that is beautiful, seriously hats off and thanks for sharing!
Thankyou, sadly it crashed today and still haven't found it. If I do find it I expect it to be destroyed.
i thought the purple coverings were solar panels.
you should do a solar plane
It glides really well. Nice wing design. This thing might be able to sustain on solar power with a few panels fitted on the wing.
Beautiful and I’m a true fan of balsa but it’s only from a lack of understanding of the modern hobby to think this would come even close to the radian in terms of popularity and sales - folk don’t build anymore, they can’t even fly without complex stabilisation and airframes they can dispose of and replace with “just 2 screws”
Just amazed by your work
Beautiful build
beautifully built and covered.
That is a thing of beauty
amazing fuselage from balsa. great colours!
+Wernerrrrr Thanks. After I uploaded this I realised I forgot to shop the bottom, which is black instead of metalic copper.
Excellent video and a great test flight - congratulations.
Funnily enough the tip I really liked (and may well 'steal') is using 4mm bullet connectors for anti wing rotation. I think they may also make neat hatch retainers, helped by my usual small magnets.
Thanks, mine were 3.5mm bullets, Don't forget to tape the wings on :P
Amazing craftsmanship, thanks for sharing.
Very inspiring build with Great Tips, Very well though out design Huge thumbs up in spades
Something with that good of a glide ratio and the right mix of battery, solar, and capacitor would be exactly what we'd need for a network of solar aircraft for worldwide wireless internet.
Excellent build. You've got skills.
Any plans or at least some measuring moments so I can reproduce this model plan ? Amazing craftsmanship and awesome flight performance. Thank you for any feedback.
how i can download the plan for this aircraft??
Beautiful glider! Any chance you will offer plans?
Stunning build fella.
Holy schmoli! What a beautiful job you did! From scratch!!! One thing I don’t get is why you’d put such cheap/garbage servos in such a fine bird?
love it
well done! Its so good, I thought it would just fly away at the test throw :)
Nice video and top effort on the glider...which I will call the RK.
Awesome build
it looks amazing. can you show how you covered the wings in another video?
hello, I have a video titled "balsa wing covering tips"
on my channel that will help you.
That's a brilliant floater, what are the rough dimensions of it, such as wingspan, wing chord and lengths, thanks ?
Thanks, Wingspan 2530cm Fuse length 1340cm wing cord 27cm
Sorry to hear that. Add a locator next time. Great build.!Only thing you forgot is what airfoil you used, how you see the wing incidence and CG determination.
What do you mean? He lost it?
That`s a nice piece of design and workmanship. Seems to fly OPK too!!
Thanks.
.Very fine workmanship.
Flies pretty sweet too.
Hats off to ya laddie. :)
Thanks!
Love to see a set of PDF plans, Great job!!!
+Kevin Matney I only have what I drew up sorry.
Hats off to u bro that was AMAZING! But seriously that was really good.
Beautiful work.
Thankyou!
That's just beautiful ...
thanks!
Beautiful build. Thank you for sharing.
Such a clean work, well done!
that's very cool, the wings are only attached with the connector and the carbon rod?
do you have plans for it?
The wings are taped on with a low strength tape. that connector is just to locate the wing.
@@filippoorlando5175 I don't sorry.
@@TheRattleSnake3145 ok, i'm planning to build someting like this
awesome I thought you were gonna throttle up then lol great job
thanks.
So cool stuff your design is also very good.
To claim to be a radian killer is a big claim, its a great glider for a foamy, i believe you have done it. How is the penetration of this glider/ Your l/d looks to beat a radian by a bit. Give us more please. I am going to extend the wings of the radian by 2 to 3ft and see what happens. i will let you know thanks!!
penetration AND float can be seen in $2,000 DLGs To get both in a balsa electric poly, some tradeoffs will have to be made.
if you are modifying a radian , you should check out my triple radian videos. the one with the emergency parachute was fun.
Fantastic build! Beautiful.
thanks!
Terrific build! Thanks for sharing. Always interesting to see how someone else dose it. I especially liked how you used the electrical connector for the wing position. I hope you don't' mind if I steel your idea! LOL
Don't forget to tape the wings on :P
Amazing plane!!! Could you please make a video with all the dimensions so I could build a mini chuck version.
it's a fairly simple design so I suggest that you try your own design, you will have more fun and get much more satisfaction seeing something that you have designed and built flying well.
Beautiful glider!
I'm planning to build one myself, but I do not dare to build it by drawing wing plans by myself. Since I do believe in your experience, I'd like to ask you to recomend me some printable plans similar to yours..
thanks! I'be only ever built of what I have drawn up myself so I can't recommend any sorry.
The best way to learn is to do it yourself!
give it a try in a smaller scale.
Beautiful aircraft.
I would also love to see a flite video of this, some slope soaring maybe?
there is flight footage at 10:33 . I don't live near any slope soaring sites sorry.
Thanks man you gave some idea for my wing joiner using bullet connector
Make sure you tape the wing on with a low adhesive tape, the connector itself isn't enough to hold it on. just peel the tape off when you want to pack up.
Don't forget to use some tape to hold them on!
Buen trabajo de Aeromodelismo.... Saludos
Really good job
Well done, indeed, its 10x better than a Radian for sure.
+FGDude Thanks. close to 50% more wing area and less drag than a radian. it weighs 30 grams more than a radian but climbs as good if not a bit better.
+TheRattleSnake3145 Dont forget to mention the looks ;o)
Its a nice glider I can see that by the first trow. Good job !
Nice work man.. Haven't seen an upload from you in a while. Looks like a dream to fly
+DCVINRC Thanks. Yea, been slack lately. I have 2 more scratch builds I could put up when the stuff is edited also a CL-84 tilt wing VTOL I'm keen to film, just waiting on good weather.
handles just as I was hoping.
Sir plz tell me this details of this RC glider plane, like wingspan, fuselage length, motor kv, cg point and maximum weight ( including all electronic ). Plz reply me
Great instructional video. Thanks for sharing!
Well done, very nice build.
+RCHELIBUG Thanks, already on to my next build now.
Nice build! What carbon tube are you using?
Very nice build and vid. Liked and subbed man. Cool
AWESOME. that's so smooth. can i get the the lines plan? i wanna build one.
great job! what an amazing glider! :)
thank you!
I wish you would make a set of plans and put them on so we could print them to build the glider, I think its beautiful. I live in Arizona usa. ron
honestly, if you have the skill to build this, you could most likely design it too.
Give it a go and you will have fun learning!
I'd like to give it a go!! You're right we can do our own designs, can you share just a bit of info on a few key dimensions like wing span, wing cord, dimension from motor mount to wing LE, and length of boom? I'd like to get these basic measurements just so I don't need to add a ton of ballast to get the balance on CG!
what I do to make sure I dont need to add any weight to get the cg right is make the fuse ahead of the wing longer than I think it needs to be. Then when the rear half of the plane is finished (servos and wire installed etc ), I temporarily place the motor and battery up front so I can adjust where it needs to be. Then cut the fuse as needed.
That way no weight is needed to correct the cg.
Wingspan is 2.5 meters
Cord is 28cm
Your materials will likely weigh different so your fuse length will probably be different but:
LE to motor mount = 29cm
LE to rear end on boom = 1.9m
@@wshurmatz1 just do like I do. find a plane you want to build and then build a plane that fits those measurements and Design. I haven't built any big gliders yet but I've been building small Balsa gliders from plans I find online. But I don't have a printer to print out the pages so I just take the measurements and draw the lines in myself by hand.
amazing build dude!!! greetings from Italy.. i subscribe your channel !!
nice build bro
Did you post your build on RC Groups ? i am guessing your wing root chord is 8 inches ? i am Most interested in your Leading edge shape of the wing , its very hard to tell from the video but i am guessing you are shaping the LE to achieve a more modern air foil ?? any little tid bit of info on that would be most Awesome
looks very professional!
thanks, I've definitely improved since my first plane.
sweet glider, have u got the plans u could share, cheers graham
Love your videos , such a great builder .
+Scott Thompson Thanks, Im always building something. At the moment im building an air/swamp boat.
very nice work!!!
She took to ths sky like a home sick angle! Edited: Nooo! just found out the fait of this beautiful bird
beautiful job.
Awesome glider and great craftsmanship.
What is your angle of incidence, and why did you not bother with ailerons?
Also, what is the rib spacing?
Thanks
50mm
I just guessed at the angle, I didnt put ailerons because of the extra weight they would have added. They simply aren't needed with this style of plane.
hey, Rattler. After looking at your plane for the umpteenth time I really think that you have a winner there. Nice job. On 14th Oct `16 I hope you still have it. What airfoil did you use? What is your location?
yes its still in my current fleet, I take it out on the light wind flying days. Airfoil I used was an SD7037.
Hallo again, Rattler, I`m using that profile (7037) on one of the panels on a 160 inch tail-less wing I have on the board. There IS a slight under camber but so small i wonder if it will actually be there when I finish and cover the wing!!! What part of the Great Continent are you based? I will be down there from mid Jan to mid March, Adelaide and then Tassie for 6 weeks. I wish they`d let me stay for ever!!!!! I prefer light wind and calm days for flying too!!
Nice job
Wow...I wonder what the glide ratio is!
How did you find the perfect wing shape? Beautiful plane!
Can you give me all the technical specifications of how much material is composed this model and how many ribs consists wing.
For your wing tip, what type of adhesive did you use to join the balsa?
And also what kind of adhesive for the vertical stabilizer to the carbon fiber fuselage?
I'd appreciate your response. I'm building a glider for a school project :) Beautiful Plane!
Kenny Mcguire I used epoxy for the wing tip but any balsa/wood glue should be fine for that. I only used 5min epoxy because I didn't want to wait. For the tail I used epoxy, just make sure you do a test piece first as I have found some epoxy/ carbon combos that didn't work at all. and scratch the carbon with coarse sandpaper where it is going to be glued.
Thanks for the info!
You've mentioned you don't have any plans but any chance for at least the standard dimensions? fuselage length (pod, and from the wing to the stabilizer) wing span and area, etc? I want to build one similar.
Hello , Wingspan 2530cm Fuse length 1340cm wing cord 27cm leading edge to nose 33cm but this will likely be different as you will be using different material and hardware.
Loved watching this video and the great flight characteristics. What wing profile did you use? I'd like to try this one out.
+Brad Dixon I cant think of the exact one off the top of my head but it was definitely a thermal soaring foil.
Hey mate to u have a plan at all on pdf? Looks like a fun build
I don't sorry. I need to repair the film on the wings but this glider is still flying.
well done.
It appear you have a basic cookie cutter fuselage design you like to use. Using a 40mm prop spinner, the fuselage appears to flair out to be about 60mm. Is your wing mount on the fuselage also about 60mm? How do you guesstimate the tail boom length needed?
Its the least drag I can come up with / build. I fully build the tail first, with wires and servos, then build the nose length to achieve the cg needed.
Beautiful job! What's your RTF weight and square inches of surface area?
740grams without battery and 1008 square inches. I could have saved 50 or so grams of it used a normal film instead of the metallic but I had already done most of it when I realised how much heavier the metallic is.
Weight is comparable with the Radian but you've got double the surface! Now I know where that ''float'' comes from. ;]
Amazing.
