I used to build these kind of airplanes when I was teenager (45 years ago). Saved and spent all my allowance and summer job money to enjoy this hobby. Brought back lots of fond memories. I have a kit for a 2M sailplane that I've been putting off for a while. Hope my radio still works. You've inspired me to get back to it.
Yep I was the same, all my models were scratch built from plans and the purchase of, balsa wood, plywood etc, enjoyed the building as much as the flying. 👍
I used to build model sailplanes 40 years ago it's a shame that the great little hobby shops are gone we used to meet at our local shop and then go to our favorite slope Your video brings back so many great memories thank you
I've built lots of models and still watched your video all the way through. I'm a big fan of old school gliders (and don't mind imperial measurements 😂). I must say you did a great job encouraging others to have a go at building a model, and totally agree with your sentiment at the end - you can't beat that feeling of flying something you built yourself 👍
Hi from Australia.... just would like to thank you for the great video and the incentive ....at 68 years I am off to build my first aircraft and the course sounds great ...............thanks again
Great build, nice flight. You made me want to restart my hobby from the ‘80 s. I was member of a RC aviation flight team at the time. Still have my models. Great hobby! I love balsa
Nice to see someone doing this old school. You gain so much understanding and skill that make so many other thins in RC easier. I’ve done this maybe 50 times in 40 years.
Oh yes my first ever glider when I started in 2010. Still have it and love it. I think I'll go fly it this weekend. p.s I'm 59, so started out a bit late but this is my favorite of the other 10 in the shed!
I miss RC sailplane building and flying so much. I was pretty active over 10 years ago but then a series of things got in the way and I haven't gotten back to it. Maybe some day... I've still got foam cores for a Dodgson Lovesong and Camano collecting dust.
Nice build! And a very watchable video! The cheap HF belt sander really helps with the nose and wing tips. One change I made from the plans was the hatch attachment. I shaped the hatch so the leading edge of the wing fit tighter. Then glued the hatch to the fuselage at each end of it. About a half inch on on the front and an inch on the back edge. Then I cut the hatch at a slight angle so it formed a wedge. The Monokote fills the gap made by the saw so it fits. Just add more if it is too loose. Remember to make the saw cut negative in two directions so the hatch wedges in from one side and can't slide up. It is simple and clean. I've done it on most of my gliders and never lost a hatch in 35 years in flight. I have lost plenty in the car on the way to the hill, but they were always the rubber band held ones, or the lever!
Greetings and congratulations from Calcutta India. You remind me of my Olympic 100” Scratch built from plans I fully agree that building gives great pride and satisfaction.
When I was a teenager every school holidays my mum would let me buy a balsa kit to build. It would take me two weeks to build it and two weeks to fly it before it hit the ground hard enough to break it....then it was onto next school holidays. I must build at least a dozen planes during that time. Best fun and most productive time ever.
absolutely stunning build! i love my 100" riser. It has the old school KRAFT Systems servos in it too! It may be the best looking balsa glider of all time
Great build I'm happy to see that rc modelers haven't abandone our skills to build using balsa and thin plywood. Its hard to find kits like that now, since every thing has moved towards form and derivative composites. The composites add strength just wish more the older kits were still available. I personally encourage you to go forward on your quest to create more video mini courses of this sort.
Awesome build ! Beautiful covering and flying ! I have built 2 - Greatplanes Spirit 100's...and it such an amazing feeling when you build out of a box, and do the Maiden... And what I use for the CA kicker, is sprinkling a bit of baking soda on the CA...works as good, and saves a few bucks. Happy flying !!
I'm from SE Iowa near the town of Montezuma where SIG is. I once flew in a contest with the guy who designed the 2M Riser. He told me that designing the plane was the easy part; figuring out how to get the parts cut out of the least number of available balsa sheets and getting them all to fit in the smallest possible box was the hard part.
I agree, to build a balsa plane is a really nice thing. Even more if you do it from the scratch, many plans are available as pdf files in the Internet.
This plane and a Bird of time were my last two builds way back in the day. I did add a carbon fiber strip to the bottom spar of the Riser and boxed in the spoiler bays so grass seeds would not get into the wing on landing. Your build looks nice. Good luck with it. Mine flew very well.
Great video and great build! One thing you might find useful in the future is to consider putting super lightweight fibreglass cloth over the nose and wingtips before you cover. Those are the places that tend to get damaged over time and it adds a lot of strength and puncture resistance for very little weight penalty.
Oh what a classic! I never built one but flew with them and they're wonderful flying gliders. Very cool to see they've kept the glider going with a laser-cut upgrade. Stick-built--your medicine for a stay-at-home Fall/Winter! :-)
I order a Sig Riser from Ebay and it is due to arrive today. Your video was very helpful in knowing what to expect. Reminds me of a Dynaflite Butterfly I built about 30 yrs ago.
I love building with balsa. It’s really sad that there are longer any kits available: it makes the barrier too high for newbies wanting to give it a go.
nice work i spent my youth learning to build. last one i build was a wire to handle ver. thing is i never got to learn to fly i spend weeks building spending sometime 100 of pounds for everything only to smash it to bits as it came down... i should of had lessons first. still i love building or i did when i was a kid. im 50 now but still pulls on my heart strings to see a glider fly. it always did ill i had was books to learn from. haha. i used to use wax on my plans so i could see nice n clear. hot wax and an iron melt it all over the plans. parafin wax works to. in liquid form. thanks for your vid.
I am going to try and find a kit. Love your video, I built two similar planes when I was 16 and 17 years old, many years ago. I remember it is exciting to fly your own build. Thanks for sharing
Brilliant video, watched many times and used for reference point whilst building my 100 bought last Xmas (2021) can't find any for sale now so poss last one in UK, finally got the 100 covered this week, don't think I'm gonna get time to fly her this yr now, will have to wait till spring, keep up the good work and videos helped a lot Graham
Congratulations for your video. SIG RISER 100 is a classic glider of the old school. I am according that there are many sailplane kit better that RISER, in germany and USA, but the price, and construction material, without Carbon Fiber and fiberglass reinforcement its better for old techniques. This is a relaxing bird for sunday flyer. For contest you must search vladimir models, or other czech models but you must be a biggest budget also. Congratulations again Joy.
Thanks for a great video. I just received an Aquila 101 kit and plans. I never built a balsa plane but after watching your video I am ready to get started. Looking forward to seeing more of your instruction videos.
I had a Carl Goldgerg Gentle Lady I paid 19.99 from a Tower Talk in 81 after several moves the last going thru a flood,which unfortunately destroyed it still in the box,enjoyed your video,one day I will build the Gentle Lady,as well as the Sig Riser I've had my eye on for a while
I'd really like notice of all upcoming build videos, ( good for refreshing my old talents) Haven't built for some years but loved it. Great video thanks.
I like that you use traditional wood glues and modern cyanoacrylates as well. Both have their places, plus Epoxies to make a strong and light airframe. Don't worry too much about building a glider like this very very light. It will still fly wonderfully if it is a few ounces heavy.
drilling out the noise with a spad bitt very slowly from the inside will take more weight, the bottom of the wings gets covered first then the top. spruce is better on the leading edge to make the elevator stronger, leave the legs on the rudder to drill holes in the fuse, so the rudder won't break on the first flip over. glider builder for over 40 years.
Nice to see this build. I personally have many fond memories of building balsa RC planes. I also have a brand new, unopened Sig Seniorita kit that I will build for electric some rainy day.
Great video really enjoyed it, have just brought a glider kit, the Krick Habicht. Have been flying a while on and off but it will be my first build, a little nervous but equally exited and this video really has me inspired, thank you for taking the time to film and share!
Change the nose out for a propeller and battery. It will save it from crashing is you also add in a “Sensor assisted flight envelope”. You can still crash it but with it, it’s hard to do.
This used to be the norm for any model kit you got, although some models came with the "new" veneered foam wings, but you still had to build the rest. For me the building was just as much fun as trying to fly the models :) - Enjoyed the video, took me back to my childhood days :)
great video. We can get those pretty easy and cheap from the maker over here in USA. If you ever make it over the south west of ireland you should look up James Hurd and he can get you out for some dynamic soaring.

@@russcole5685 Sanding is no problem with wood-glue. And the moisture is mostly water:)) And the speed is for most connections no problem. It is dry in 5 to 15 minutes.But hardening out takes longer. But who is in a hurry when building models? :))
This hobby has totally changed. I last flew an 80" Hangar 9 Cap back in about 2010. My last flight and then I got out. LIfe happened, I sold years of parts and equipment. I was mostly a kit builder all my years. Now...good luck finding a balsa kit at all. Sig. Goldberg. Midwest. All the old names. Go see if you can find a kit for an Astro Hog or a Goldberg Cub or a Stinger by Lanier. What happened?
CA is OK for tacking operations, but Alphatic Resin/ Woodworking glue is better for bonding Balsa and Plywood. Nose Blocks should always be epoxied (they take more of a beating than you might think). Imperial measurements may be confusing for a Metric country, but Imperial measurements with their fractions are easier to hold proportions in your head. I've been using both for over 40 years and interchange them. The Riser 100 is a good beginner's kit, and the laser cut kit of today is far superior to the "die crushed" parts of the past. There are plans out there for the Mark's Models Wanderer 99, Craft-Air Wind Drifter, Airtronics Aquila/ Aquila Grande and the Airtronics Sagitta 600/900 (Probably the zenith of 70's-80's polyhedral designs two/three channel aircraft). Honorable mention given to the Hobie's legendary Hawk, but that plane was a "Ready to cover" aircraft which required many fixtures to manufacture.
I used to build these kind of airplanes when I was teenager (45 years ago). Saved and spent all my allowance and summer job money to enjoy this hobby. Brought back lots of fond memories. I have a kit for a 2M sailplane that I've been putting off for a while. Hope my radio still works. You've inspired me to get back to it.
How is it going?
I’m 62, I completely understand your recollections
Yep I was the same, all my models were scratch built from plans and the purchase of, balsa wood, plywood etc, enjoyed the building as much as the flying. 👍
Hey I have tons of plans from kits 1940s - 1990s. Like boxes full. If you remember what you had . And I have the plans .. we can work out a copy.
I used to build model sailplanes 40 years ago it's a shame that the great little hobby shops are gone we used to meet at our local shop and then go to our favorite slope
Your video brings back so many great memories thank you
Came to the comments section to see if anyone agrees this is one of the best r/c model build videos on UA-cam.
Well done sir!

As a modeler since very young, you are on your way to a great life of modeling.I’m 75, just ordered a riser 100 kit from internet $119 plus shipping…
This is quite possibly the best short build diary that I have seen on UA-cam. Excellent stuff😀👍

well done on build and camera work i am from tipp and could not believe my eyes when you flew on bray head we need more guys like you in ireland
I think you will find a razor plane very beneficial when profiling and shaping block balsa wood.
I agree, to build a balsa plane is a really nice thing. Even more if you do it from the scratch, many plans are available as pdf files in the Internet.

The riser 100 , is a very good sailplane. I've built many,. Good job
This is great. You did an amazing job. I have been wanting to build a balsa plane for a few months. I think this is the push I needed
I love that you are using old camera very cool
Great work! I buy one old, complete Kit yesterday. Thanks a lot and geetings from Kiel/Germany.
Thanks for a great video. I just received an Aquila 101 kit and plans. I never built a balsa plane but after watching your video I am ready to get started. Looking forward to seeing more of your instruction videos.
Keep doing your amazing work brother, wishing you a great success.
Thank you so much.
I use both Imperial AND Metric units of measurement. I get along fine with both ! ! ! No reason to "HANG" anybody ! ! !

True, In a windy slope I had to put a lot of weight to keep it flying straight.
Oh, I so want to build again!
I am interrested in this course
You are the best flight macker in the world

Great Build also
This is beautiful reminds me of my Olympic 650 I had to build from scratch as a kid
I appreciate for hard work in the build process.
Great video really enjoyed it, have just brought a glider kit, the Krick Habicht. Have been flying a while on and off but it will be my first build, a little nervous but equally exited and this video really has me inspired, thank you for taking the time to film and share!

Nice build and beautiful soaring site.
Очень красивые игрушки и хобби интересное. Сейчас делаю гидроплан из DEPRON 5 mm размах крыльев 1,8 м
Nice vid, JP. I built my 100 (same colors) without spoilers. Lost it in a cloud. Long gone, far away. Sad!
congratulations, its a Superb build and it flies great. Keep it up
Hi I have only just found you on my computer, & I would love to see the hole video as I have never built a glider myself thanks
excellent work, I would be super nervous on the maiden cause of all of this hard work
Nice Work 👍🌷
Happy Flying 🙂
Man what a slope site! I always have sleeping dreams of finding almost flyable hills. Not many good ones in my area.
Nice job! I need to get a Riser 100. It's a type I've never built.
Beautiful video and a awesome place to fly...congratulations
20 minute vids are perfect length for UA-cam. Also I agree metric FTW
So cool !! I love your plane design bro
I would've used colorless transparent film so as to see all the wood. I'm cool.
This used to be the norm for any model kit you got, although some models came with the "new" veneered foam wings, but you still had to build the rest. For me the building was just as much fun as trying to fly the models :) - Enjoyed the video, took me back to my childhood days :)
Wonderful video and elegant machine! Thanks
Do we launch the glider with the wind direction or against the wind direction?
You typically launch it against the wind
As a kid in Australia many years ago we learnt imperia, after a couple years in primary school we changed over metric a much better system.
I cant wait for the full video. I ordered a kit.
I almost enjoy building more than flying. Although I use more of a "new age" methods: foam sheets, 3d-printing, composites may be coming soon
Beautiful build
great video. We can get those pretty easy and cheap from the maker over here in USA. If you ever make it over the south west of ireland you should look up James Hurd and he can get you out for some dynamic soaring.
Great build and beautiful flying site!
Thanks a lot!
“Excellent Job” great flying aircraft ⭐️⭐️⭐️⭐️⭐️ + 🎖
Very nice, a friend of mine flew his riser in a ridge and never saw it again 😅 this gliders are super fun!
Hahaha
Tehnik pembuatan nya sangat rapi
I think the wigs are the most satisfying part
A real good job I would like to get back into it but too old I enjoyed watching you work. Keep up the good work and fly more Thank You.
Fantastic video. I'm in the same school as Carl, below me. Old school builder myself, but have become spoiled by all the ARF and BNF stuff out there these days.

What???? Wow what patience!!!
So amazing.
I would use PVA glue rather than gorilla glue as GG is so hard, sanding it against balsa results in over sanding the balsa, GG has its uses, especially around areas that require strength like the wing joiners. Super glue is good for areas such as rib caps and along leading edges to give them some ‘ding’ proof.

Ca thin to penetrate, then fillet it off with medium ca, Way better way of getting stronger joints

Interested in this hr video.
