I used the standard small "9 gram" servos like I use on everything. I used a 2200mah 3s and a 3200mah 3s but It could carry a 1000mah or even a 4000mah. The motor was an eflight park 400 with 18 amp esc. but that motor is way expensive compared to the generic ones.

"$5 Trainer" original video www.youtube.com/watch?v=LKt6b...
I apologize that the title of the referenced video is misleading as the cost of materials in not $5. When I originally made it, I only had to buy a $5 sheet of foamboard and all the other materials I found laying around my parents house. The name has since sorta sunk in and I'm not sure I can undo it.
I made the "$5 trainer" while on Christmas vacation at my families house home from college. I wanted to do a project with my little brother. I had been doing some rather tedious and complicated projects (chainsaw plane and I put an autopilot on my big flying wing but didn't make a video about that) and I wanted a break and to do a simple project to get back to my roots and demonstrate that you don't need to do a whole lot to make an airplane.
I was surprised by how many people requested a build video, because I don't particularly like watching build videos, though there are interesting insights and tips, they are just long and I'd rather be making my ideas come to life (or actually working on my degree).
But I didn't feel like rebuilding that same plane, partly because I don't still have that blue wonder motor but also because I would rather spend my time making new things.
So this video is a new airplane design, but made with the same materials and techniques as were used on the "$5 Trainer."
Hope I can inspire others and provide insights on my work flow. This is a fun method because you can make the fuselage have whatever cross section you want and make things look kind of scale. As opposed to a hollow square foam tube.

Samm was a great engineer...every degreed engineer should watch his videos. RIP brother!
Most engineers are thinkers than doers. It's fucking easy to get something done than think about getting it done. That's how things worked in the 60s 70s, the era that produced great aircraft.

I’m really gratefully there was a conclusion so we had closure, thanks for the final video
This video, flying door, and rc electronics for noobs are my favorite videos.
Rest in peace, Samm.
We all miss you!
my first rc build was inspired by this video. thank you, sam. May you rest in peace
I watch this video so many times. Love the simplicity. Awesome video! thanks Sam Sheperd for sharing your air plane planes and mostly the power supply info.
Py0
I really didn't want to build the same plane twice. So I hope this is okay.
When you're making the fuselage couldn't u just hold a wooden ruler up to the foam??
Samm Sheperd mate, may I get the PDF on how to build this please?

Well done. Love getting people into the hobby cheaply but learning too. Stellar job!
+Eric William -MKme Tech Thank you sir! My hope in making video's is to inspire people to try it out for themselves.
Thank you very much for being my first supporter on Patreon! What I do on youtube is not financially profitable in any way, that's not what I do it for and I'm not going to beg for handouts. But your pledge is worth over 1000 advertised views of my content, so thanks!
***** No problem at all. I know what it is like with TH-cam and Patreon as I have both myself :) Best of luck with all your builds.
***** Looks like you got a few more supporters ;) Cheers
I got hit by a reddit bomb, which is nice
***** Excellent!
just got me back into rc selfbuilds thanks for sharing..
+Chris Barrett Cool man be sure to upload a walk around of whatever you make and share it! I'd love to see.
very impressive for a $5 build and appears to fly like a dream.......
unfortunately , look at the description. $5 only for the sheets of foamboard. motors and other electronics costs more.
true but I think $5 for the airframe still fits the description......
Saif Hakeam yes, it's a bit misleading since a trainer is for someone that's not in the hobby and they don't own a transmitter or other parts that can be reused and repurposed
Niall Duncan i love rc airplane more than quadcopters but dont have access to a park or open place anywhere close :( so i cant make one 😭
++Saif Hakeam - ass. wr.wb saif! right..right! it's impossible builded by $5 cost only. wht about the electronics..:( hehee...
I've just been watching a few of Samm's videos and I came across the comments. So Sad 😢 to hear about it. My heart goes out to his Family and Friends ❤️
Awesome video. I totally agree that landings and taking off are the best parts!
Also as a real life pilot too, I love kinda listening to how you think as you are flying these models too, I'm the same way!
dude this thing flies awesome, so smooth and perfect speed for a learner
I have recently made my own rc plane with a hot wire and Styrofoam.
It fly's decently but I'm still a beginner pilot and crash it a lot.
I cover my wings in paper but have to add vortex generators to prevent stalling.
This is the first rc plane I ever made and the second I've ever flown.
Nice! The fuselage could have used some more love and passion... but I am not here to judge! I like the overall idea of it. By the way the slow motion video in the beginning is awesome.
This was sweet man. Cool video. Glad you made it.
I plan on ordering everything from your list you made. Thanks man
GREAT video. You're not breaking the mold. You're Making the mold. Fantastic scratch build.
Lovely! Thanks for showing the hot wire cutting. I'm planning to make a cutter my self. I can see you love the landings! That's what I have been doing to. Landingrounds, getting it perfect 1,3 X stallspeed. This is good training and will save your ass one day whenm one needs emergency landing :-)
+LA6UOA You talk like a full scale pilot :) 1.3*Vso= standard final approach speed. Feel free to ask any questions about hot wiring I'd love to help!
Wonderful vid and idea behind it. I don't throw out dull blades though, but sharpen them to better than new. A little Buck kit with 4 inch stone is more than adequate. Be careful, with your progression into hot wired forms you walk the slippery slope of sophistication. Ha! I like any construction method that builds planes. Your family, being with you and sharing your interest made me jealous.
Cheers, Samm. Your videos are fun and informative. I'm not sacrificing my guitar strings, so I'll stick with the Arman wing for now. Happy flying!
+Brandon Cooper pick one up individually from a music store for $1!
Hot wire! Back in ca. 1982 I was using it to shape polyethylene honeycomb (visualize soda straws glued side to side) for NACA section daggerboard cores. Nice to see that it's still around.
I'm still watching your videos Samm. I hope your family is recovering.
Something about the way the video is edited and your monotone narration is hilarious. Real great work here.
+Kniroid I swear I feel like I'm really pushing myself to talk lively haha, but glad you liked it.
Yoiu dont even have to try man! Alot of character bleeds through and We get the info perfectly.
+Kniroid: Daniel (rctestflight) has the same style. In fact there are times when I can't tell the difference. Both have great presentation skills, great RC plane ideas, and great flying skills.
+David Jensen I agree! sometimes I'm waiting for him to say "bye" at the end.
David Jensen I started making planes and watching rctestflight around the same time (summer 2013) and I always resonated with his content and style the most. Even his other hobbies like skiing and mountain biking. I grew up in a surf town, he in a ski town. He's been at it a lot longer than I have and because our styles are so similar I try to avoid accidentally being TOO similar.
0:59 The shwing, i'd say!! So cute!
Awesome work, man! 😀
Thanks man. You made it look so easy.
Interesting. I'm an old man, who learned this stuff in the early '70s with balsa wood and rice paper. You method is certainly cheaper again, but I liked making an airfoil with ribs and spars and stuff... It's a lot more work, yes, but what you get is a lot more like a full scale (WW2 sort of vintage) aeroplane... The radio gear and motor cost some money. Balsa and glue and covering cost almost nothing. I started with a Cox .049 ThimbleDrone glowplug + control line, and I was about 10. And no, I didn't have a father or uncle to walk me through it, I worked it out as I went along. Working out how to cover a wing with rice paper and then dope it, that took some trial and error... By the time I got to 4 chan pattern ships and OS45s, I also got to leaving home and riding 750cc motorcycles, and rc 'planes kind of went on holiday. That was about 40 years ago...
Very cool man! I have made some wings from balsa and modern plastic covering film. There is something very therapeutic about just sitting and cutting out ribs! I've worked as an assistant to an aircraft mechanic and helped to recover a full scale super cub wing and so the "scale" ness of it is also nice if that is the reason that you like model airplanes.
Minimum building, maximum fun. I like that. And I got some good ideas from your vids, thanks.
+Chilarai B Thanks! I just got home from flying this same airplane with FPV gear for the first time. I do appreciate all the effort people put into high quality builds, it's just not quite my flavor of the hobby.
the unfogettable name is samm sheperd in DIY rc flight makers.his R & D are astonishing.great.we miss you samm.sad feelings from india.
Nice clear well spoken video thanks for that..
Nice video and nice plane.
Great work, keep making more amazing and knowledge full videos
hey, great idea with the hot wire cutting. I use a razor, hack saw and alot of sand paper lol. I'd love to see how you hooked up your nose gear. I have stuck with tail draggers because I struggled with steerable nose gear.
If you make the fuselage as a tapering triangular tube it's more resilient/robust than just foam, you can attach the wings to the top side of the triangle which ensures they are horizontal, you can put battery and RC inside the triangular tube so are safe, and it looks nicer.
Thanks for this, really well done!
best Info yet for starting this :)
Nice and simple.
It's mesmerizing watching these planes fly. It's stressful doing it myself... :)
Dude!!! Great tutorial!
You know you got enough hot glue when the landing-gear is floating away XD
Thank you very much for the information packed video. Also for giving servo, motor and battery information for another question below. I watched your snow flying video, too and can see why you wanted to make the ski landing gear. I'm wondering if the same skis - maybe a little bigger - might work for water landings.
I see over to the side a video you made for begginers and electronics. Thanks for that one, too and I'm off to watch that one.
Thanks again for sharing. Your videos are getting me closer to making my own plane.
+southernexposure123 Thanks for the kind words! I have wondered what would happen if I tried to skim water with those skis. I think that some thicker blocks of insulation foam would be a better way to go. I haven't tried water stuff yet because I know I will get it stuck out on the lake
You're welcome for the well deserved positive comments. I'm watching your videos as I write this and I'm getting the information I need to be much more confident about which parts to buy. Without your guidelines I might have had to research for months longer.
It might be found in a video of your I'll find later tonight, but I'm wondering how to pick a motor based on plane size. I'll want to make a 4 channel high wing trainer first, but I prefer a large wingspan - maybe up to 4 ft across.
I think you're right about the water skis. Skis on real planes look wider and thicker than the thin snow skis on your snow plane. I have a few small ponds nearby is why I wondered about the skis.
***** That is a good question, and a hard one to give a perfect answer to. But I think that it doesn't really matter. Let me explain:
My very first airplane that I built, I powered with a big inrunner motor from an RC car and a random, poorly matched propeller held on with zip ties, The motor was hot glued in place and controlled with a car ESC (which means it has forward and reverse) all powered off of a small NiMh battery (also from the car). Picture here: imgur.com/1cf6M9P
That plane had a 30 inch wingspan
And it actually worked! It was nowhere near ideal, and I remember when I finally bought a proper airplane power system, I was super impressed with how much better it was.
Since airplane building materials are so light, most of the weight will come from the power system. So smaller power system will weigh less, and it won't need as much power. But a larger power system will weigh more, and it will have more power.
The lighter one will fly slower, and the heavier one will fly faster.
A good way to measure performance is using thrust to weight, however that is pretty inconvenient to try and predict and measure.
If it looks like an airplane, and its balanced in the right spot (1/4 to 1/3 back from the leading edge of the wing) than it will probably fly.
I found though that the smaller motors tend to damage easier. Their shafts would bend very slightly, making the propeller impossible to balance, and so I like larger power systems because they are more durable and faster/bigger planes are possible. In one of my really old videos here: th-cam.com/video/MhIE_ddr1gU/w-d-xo.html
That plane is not that big, only 40 inch wingspan, and it used the newer, bigger motor. And like I said, it went 75mph. however In the flying portion I only filmed it using a lower voltage 2s battery, and so it had much less power than it would on the 3s battery and It still flew beautifully even being heavier. The motor used was this one: tinyurl.com/h3x8taz
It is about twice the price of the smaller motors I talked about but I'd say easily twice the value tinyurl.com/h5vhg2t
Actually here is a playlist of all my videos featuring that bigger motor. I just realized that it is most of them... th-cam.com/play/PLuYy5ij8a6_cPitUbqTw3CBIt-3LhmSk1.html
As always, feel free to ask any other questions you have.
You may never realize how helpful you are to my questions. You go to great pains to give a good answer to a question that doesn't have one pat answer. The kind of detail you gave turns on so many lights that now I can see the hobby and the process from a few different angles.
Basically what you're telling me is that no matter what I try - well within reason - it will have a workable outcome at least to some degree of success. Then if whichever motor etc I pick isn't the greatest that I can make a different size or style of plane and get another workable result - to some degree.
And it seems you promote experimentation.
It seems you especially promote experimentation. ((-: I like that.
It'll take some time to watch every link you included, but I'll watch them all with interest and apppreciation for the trouble you took including the links and making the videos along the way and sharing your experiences.
These days its not exactly easy to find someone who is willing to share or is able to communicate in suh a helpful way. I appreciate that you are able and willing to give pointers that help me relax about the process.
Thank you so much and I'll definitely remember your kind offer to clarify any questions I have along they way. Thanks again very much.
You safed my day. Thumbs up.
For me flying rc planes are about 2/3 of the fun, the other 1/3 is building, fixing and tinkering. Good video thanks for sharing
good video, i would like to know some specs
-total weight of the plane
-weight of the motor, weight of the battery
-wingspan and how long it is
-length of the wing(front to back) and maybe the thickness at the thickest point
makes me want to fly again. thanks for the videos.
Another fine video!
best video i've ever seen in my life
Have only built KF airfoils, gonna try your wood template technique.
Bruh, your content is so good. Why the best ones get taken?
😭😭😭well said sir
this is very helpfull i really wish my home country has shops to supply me with servos
Miss you big man, RIP Benny Harvey
Great inspiration!, please keep posting. Have you tried to make a glider that could be towed up?
Thanks..You are awesome for sharing this..
miss you brother.RIP samm.
Maybe some Home Depot stir sticks that are temporarily double sided taped to the fuselage to make the cuts straighter? I love this video. This has helped me immensely. Now I can fly these and save my commercially made planes for special days. I was struggling with the best way to make solid foam airfoils. THANK YOU!
Hey Samm it seems like you really know what your doing. So I have a question/problem. I'm flying in about -5 degrees Celsius and I use a 6 channel hobbyking radio. I made a simple soarer from Flitetest and every time I try to fly it, I'll hand launch, and then every single time I completely lose all control of the plane, the motor shuts off, the servos stop working and I won't have control until I'm about 5 feet away from the plane.m I do don't know what the problem. I use a 30a turnigy esc with a 3a bec. Please tell me what I am doing wrong, it is driving me crazy. Thanks
Great Job,
Very cool video, nice plane and a very attractive lady holding the wing ☺
Hey Samm! I love your work and you've really inspired me to start making Airplanes. I've made about 2 that have soared straight into the ground. I can't really afford more crashes now. I feel like giving up but the hobby seems so fun lol.
For an airplane like the trainer, could I use a 1000KV brushless with a 3s 2200 mAH battery or would that be too heavy. Haven't had any success with that combo yet. Also since you made a piece of foam board fly, does the airfoil shape and efficiency even matter?
He passed away and won’t be answering… I’m sorry. 💔
Man, I really miss Samm...
Best video ever!
very good built... and seems to be very simple and stable as well.. keep going.. it ll be good if you post correct dimensions of the plane. thanks

Who cares how it looks it flys wonderfully,great job mate!!!!!!!!!!!!!!!!!!!!!!!!!!!
2:31 omg that was satisfying
Hello again,
I've been having loads of trouble with my hot wire cutter. I have a similar frame you have (it's spring loaded.) I'm using 24 gauge nichrome wire that is being fed 18 volts by 3 semi used lantern batteries (6volts each, 3 in series.) The problems I have involve the cutting. I'm having a difficult time establishing the center line to line up my pink insulation foam. I believe I've e the problem is due to the uneven edges of the foam, but I think I can solve that with a new uniform block. A big problem I have is that the wire, even though it is stretched, tends to slightly bow, giving the profile of the wing a slightly curved shape. Last but most certainly not least is the leading and trailing edges. I always screw them up and I don't really know how to fix it. Do you have any tips to help avoid getting a crummy jagged leading edge, and uneven trailing edge. I'm going to get a new block of foam because I just burned through a $22 one and I feel defeated. Please help.
AMAZING VIDEO.PLEASE COULD YOU TELL ME WHAT IS THE NAME OF THE PROGRAME THAT YOU ZOMMED IN THE AIRFOIL
great tutorial... I'm a 1st time builder so I'm brand new to this. stupid question for you: how can I determine the size do the airfoil? how big should I make it for a trainer plane?
+Taraut Romain do you mean how big to make the wing in total area? In general, I'd say it's all proportional. My saying is: if it looks like an airplane, has good power to weight, and is balanced a quarter of the way back from the leading edge of the wing (don't overlook this), then it will fly. My advice for a trainer, is to make it simple, lightweight, and relatively big, and don't be afraid to make the wing long.
I also just made a video overview of electronic components if you aren't used to those yet.
I always liked your videos rip
Where did you find insulation board that thick? I can't seem to find anything thicker than 1 inch,
Hi Samm what prop did you use? and how can you find a suitable one for the motor?
thanks
Maybe for the fuselage you could set up the hot wire vertically like a bandsaw? It would make the cut much more smooth and accurate.
Hi, I am going to make one similar to this but need simple help.can you please tell me the ratings of all electronics used in your plane like motor rating,ESC rating,battery rating,propeller size and servos.please I am waiting for your answer....
is it easy to fly after building it ? or did you have to make adjustments before being able to fly ?
what are the dimension of wings and fuselage? thick of foam you use?
Are there starter kits with engines, battery, servos and the rc controller on sale?
Sir can it go invert flying for long time, if there is less than 180° angle between 2 wings?...
sorry to say but he passed away.
Gave up on the Armin wing. Awww...
Hi Ed. I wouldn't say I gave up, I just like real airfoils :)
'real airfoils'
Try KF airfoil has better lift than Clark Y.
What motor, esc, and battery did you use?
can you give a list of the electronics
i really can't find it out
could you please reply?
Any guides you could recommend that would help me set up electronics for the control surfaces? I am a total noob.
There are lots of forums out there for your questions. To see what the components are and how they interact, watch this m.th-cam.com/video/7uOr0nMv0-8/w-d-xo.html
I think a great first project to figure out RC electronic components would be one similar to this one m.th-cam.com/video/lb7DPmaW8qs/w-d-xo.html
+Samm Sheperd (SNRS) Crazily helpful links, just watched them and they have helped a lot. You sir are a scholar and a gentleman.
+MultiPuma1234 Thank you, and if you hadn't noticed, I recently made my own version of the video I referenced for you, incase that helps at all. th-cam.com/video/j61Q3e8AFR4/w-d-xo.html
For cutting a straight line free hand, simply have a thin piece of wood along with the foam. Use your meat clamps (hands) to lock the wood to the foam, and cut along with the wood as a guide. When you need to change angles just let loose a bit and shift the foam vs the wood, then tighten and keep going..
Muy ingenioso y excelente diseño para volar nocturno, pasarla bueno o simplemente experimentar
hi,its really nice. can you send me the dimensions of the plane pls, the body,wing,elevator etc.
What should be the angle of attack of the clark y airfoil for max lift?
The airplane is basically just a big tool to control the AOA of the wing. You use the elevator to control AOA
wow, i will try it!
Little dogfighting at 6:43 too ... awesome !
can you make an offical parts list I want to start making rc plane but don't know where to start
Hi
Where did you get transmitter
Plz tell me the web site
how much would it cost more or less?
Did you know what the final mass of the whole thing was? I'm sure it couldn't have been more than a kilogram or 2 but I know all the parts add up
Thank you!
Well is this important to put servo at back wing also
