What about the tail design?
Very helpful video ... Thank you
The Best of. thx for explaining. I am trying to find out why my model does not fly properly. We will see what happens when I applied information from your video
Que maravilla. Espero algún día poder iniarme en el maravilloso mundo a RC. Gracias por compartir tu conocimiento.
Nice to have an explanation provided by an engineer. Thank you for taking the time to provide such a detailed presentation.
Interesting read and superb diagrams!😊
Very useful, thank you sir!
Se podrá usar un motor ventilador, de los que venden en alixpss?
Que bien, por fin un vídeo para armar un mig-15
Could you please tell me what book you got your tables from?
Hi there. Except for table 1, all other tables are from my own test on the test bank shown in the video (1:55) . As a Mechanical Engineer and Aeromodeller, I wanted to contribute to the hobby.
Thank you, I was a bit confused about the motor size and kv for 10x5E APC propeller, due to this amazing video i have pinned down the required kv i.e 900-1100 kv , i just need to find a suitable motor size for the above propeller . Thank you so much for the help
Hi. I am glad this video was useful to you! Have fun.
Muchas gracias por la información
Wow
🤔
I used your video to design a rc plane of c rating with 8 , it flew well . Thanks.
Hi victor the table at minute 7, is it for 3s battery? Also motors manifactirer usually provide a best prop for a certain voltage. Thanks
Yes, Pretty much.
Saludos Amigo Víctor, excelente creación, un gran abrazo
Saludos Roberto. Gracias . Gran abrazo.
Queria pedirle informacion o mas bien ayuda para la distancia entre el borde de ataque del ala y el estabilizador horizontal. He visto viseos pero queria recurrir a sus conocimientos
La distancia L entre el centro de gravedad del ala (CG, aproximadamente a 30% del borde de ataque de la cuerda media aerodinamica* ) y el CG del estabilizador, (a 30% del borde de ataque del estabilizador) esta dada por el producto del area del estabilizador (AE) por L. Asi mas grande AE mas pequeño puede ser L y viceversa. L depende del tipo de avion: Trainer, Acrobatico, Cargo, etc. Como referencia, para trainer, el area del estabilizador es como 25 % del area del ala principal. * Cuerda Media Aerodinamica (CMA) = (cuerda base del ala + cuerda punta del ala) / 2 Si es un ala rectangular, pues CMA es la misma para toda el ala.

saludos desde venezuela amigo! Hace muchos años le escribi referente a este hermoso hobby. Sigue sctivo?
Hola Rolando.He seguido activo, solo que sigo trabajando , lo cual me ha restado tiempo para los videos de you tube. un cordial saludo
Thanks for your turorial.....
Esto nobse entera ni quien lo esta diciendo vaya porqueria de video
Muy bien explicado y muy instructivo. Gracias
Hello - hoping you can help. I have a Great Planes Kunai glider with a balsa tail. I managed to snap off one side of the horizontal stabilizer. Ive glued it back on, bit would like to reinforce somehow. It is a thin profile - so i dont rhink i could add a carbon rod. Do you have any suggestions, please?
As a newbie, everything seems so interdependent on each other that I spent hours trying to find a way out of this catch-22. I love your experimental values tables, they make choosing waay easier. Thank you!!
I’ve made a plane with a C value of about 11 and it flew but it was so hard to control that I crashed it multiple times. I’ve made a new design with a C value of around 6. I’ll reply with my findings on how much easier (if at all) it is to fly
How did it go ? I'm designing a large filming airplane so this type of video helps a lot
Hello plz can you tell me motor spec and prop size??

Plz pdf file
Plz give me any build file
Hi Mojar. Sorry, it is a scratch built model and I did not formal files. Here is the building process: ruclips.net/video/a90j_LL21s4/видео.html You can find the 3 views of the plane in www.skybrary.aero/aircraft/p180
Muy bueno . Podes subir el plano por favor. Gracias
Hola Ricardo. No tengo plano pues es scrach build. Las dimensiones las saque de 3 vistas bajadas de Internet . Subire estas vistas.
You determine the area required to carry a certain load but is airfoil efficiency not a factor?
Hi Mel. The required area has to do basically with the wing load, but the airfoil has a lot to do with the type of flight. If you have a trainer or a jet, the airfoil of course is different. Also, the airfoil has to do with the drag. Thicker the airfoil, grater the drag,
How does thrust relate to this formula. Say 35g 1.23oz ?
Hi Mel. Sorry, I don't understand the question.
Thanks for asking. Using the formula to determine the surface needed for a load, how does thrust/airfoil/drag factor into something that flies given the determined surface/weight result? It seems to me (aeronautical ignorance here) that to achieve any degree of lift, the wing profile and thrust must factor into actual flight. For example, I have a given load (70g) and a given motor (35g thrust). How is the surface needed to carry 70g related to a design that has 35g thrust? Does surface area change based on thrust?
@@melristau If you my video on How to choose a motor: ruclips.net/video/EL1vt9ufEcE/видео.html There is a table at the beginning that relates the thrust/weight ratio according with different types of airplanes. This table is of common use by aero-modelers. There I propose a process to select a motor and propeller that has proven to be useful for the hobby. It took to me a considerable time to understand the relationship between all this variables and to put in few words all the information. Hope it will be useful for you too. I am not an aeronautical engineer, but a mechanical engineer trying to put some of what I have learned by experience in the hobby.
Thanks! Did watch. The plane I’m trying to design is based on an RC system with max thrust of only 35g! + a total load of about 70g. The lift area is what I’m experimenting with. 🙈
The hard part is not knowing the weight of the plane without making it. But I wont be bale to get the scale right without knowing its weight.
nice work. Thank you
Wow, she flies gentle!
Hello how do you select battery for this fan, also any suggestions on how to control battery circuit for beginners
I wish PowerPoints at work had a soundtrack
A bit confusing in Table (1). For RPM = KV * V ? For Power(W) = Max.V * Amp(A) ? But I found the figures in RPM and Power are not according to above formulas. Is the RPM and Power are measured figures or calculated figures ?
Hi Thar. Kv is expressed as rpm/volt, so multiplyng Kv * volts gives RPM. Same for Power. W=A*V . Data in table was obtained from manufacturers, but this data is only referential. As you see in the video calculation does not use this data.
Hi, I have a 40 size and a 60 size p51 mustang and I've been struggling to get the glow engines to work properly and I'm OVER IT!!!! I will be converting them as soon as I figure out the right combo!!!!! Both planes have never been flown and I've had both for two years!!!
Hi. Hope the video will be useful in your conversion of both planes.
this is the most usefull video on that topic on the internet ❤
Absolutely fantastic, Victor. I too have been struggling, being a newbie, to work out sizes for my rc Guillows conversions. Now I have a much better understanding. Great job
Hi Douglas. I'm glad the video will be useful for you. Have fun!
Thanks Douglas. Hope it will be useful for you.
Hello; what is ASE and how to use it,also how to use power of 1.5
Hello Paul. Sorry for the delay. ASE is the calculation of lifting area to the power 1.5. I made tables of ASE so you do not have to calculate it. It facilitates the other calculations as explained in the presentation.
Hello; Your videos are very good,but I still don;t know how to calculate the power of 1.5 with wing loads and weight,,,can you explain how to use it...its me,I have a hard head to learn new things.............
Hello Paul. You don't need to calculate it because is already calculated and tabulated in the presentation. C= total weight/(Lifting Area)^1.5 to facilitate the calculation I call ASE =(lifting area)^1.5 , so if you have the area , you look in the table and find ASE . Once you have ASE calculate C and see what value you obtain. (less that 12 is OK) On the other hand, if you can go the other way, if you want a defined value of C (say 9, for example) you can calculate what area do you need in your model. Once you have the area, you can determine the wing according with the type of selected wing.
When you say plane total weight, is it just the air frame or with esc, servos and lipo? i am a bit confused here! haha.
If you could get a real voice and maybe use cm³ (I know it's not the standard unit but it's something more commonly understood) Otherwise brilliant info.
Plans pls
This is AMAZING! Your ingenuity and craftsmanship is something I want to aspire towards!
Thank you Delfinmar. Hope you enjoy RC model airplanes
@@rcairplanesvictor9866 I do, as of now only model boats. the C-130 is also incredible. my favorite aircraft.
well I thank you very much and will be looking forward to doing my OS2U-3 Kingfisher
