DIY RC airplane 2020 | A better explanation

This article is an extension of the YouTube video, here you’ll find some more information to understand your project better and finish it, including a explanation video that shows you how to connect and set up the electronics.

Notes about this design

This is a homemade rc airplane made with very simple materials, in fact is not very durable due to the poor material used, however it is a great practice or option if you only have this material available. I recommend using a high density foam, which is stronger and will stand hits and more crashes. If you’re making an RC airplane for the first time I recommend building this design instead.

Features of this model
Styrofoam build

It’s a really simple design with simple materials.

Really cheap
This is the cheapest one

Of all our designs this will be the cheapest one but also depending on the material quality more or less durable.

For beginners

It doesn’t take too long to finish so you’ll be having fun in no time.

More about the DIY RC airplane

[1] The list of components you’ll need:

✈ Kit, motor, esc and propellers (select 1400 KV )

✈ X4 9g servos

✈ 3S battery (Due to some regulations you better off buying the batteries from a local store or pay the extra for shipping)

✈ Lipo battery charger

✈ FlySky i6 Radio and receiver (Choose mode 2)

✈ XT60 battery conector (or depending of your batteries)

✈ Soldering iron

✈ Soldering wire

✈ 40mm wheels

✈ Extra propellers

[3] Decalage angle or angle of incidence is the angle between the main wing and horizontal stabilizer and also the mean datum line of the fuselage, the maximum angle between the wing and the H. stabilizer in this DIY plane should not exceed 5º

    I used 1inch thermocol sheet and my chord is 7inches so 7×6 makes wing span 42 inches while yours is 36inches while your chord length is 17cm or 6inches so 6×6 equals 36, now till this part we are on same page the problem comes when we proceed , fuselage length from motor mount till back (total length) is according to aerodynamics 75% of wing span so for me it should be 31 inches while in your case it’s 29inches why is this gape of two inches as I go according to rule? Even if you say 2 to 3 inches on foam planes is acceptable still what about the calculations? What I designed is from motor mount till wing leading edge is 10inches, then 7inches is occupied by wing height or chord length, remaining is 14inches which is from wing trailing edge to the end of fuselage, then problem comes in Horizontal stabilizer, rule says it should have an aspect ratio of 3:1 in your case you took 35cm(9inches) width vs 15cm height or (6inches) where is 3:1 aspect ratio? Rule says H stabilizer is 25% of wing area in your case wing area is 216 square inch while in mine case it’s 294 square inches, now what makes your H stabilizer 25% of 216 square inch (9inches x 6 inches) ???? while I get 25% of 294 sqr inch as 73 square inch or 15×3 equals 75 close to 73 but here we get 3:1 ratio, then comes the elevator area which should be 30% of H stabilizer area in my case it’s 21 square inches of 73, or 7×3 equals 21 but how come as elevator length should be same as H stabilizer length as it cuts out of it(it should be 15 but how?), this is the problem I am facing, similarly in vertical stabilizer it should be 10% of wing area I am getting 29 sqr inches or 7×5 again I am getting things wrong,
    Please answer my queries, this is the basics queries to successfully design rc plane outta anything mostly folks out on YouTube make fly and then share their dimensions but no one is precise about the aerodynamics rule, please help me and correct me
