Joytrainer mini – Build a Serious RC airplane

Joytrainer mini | An RC Trainer Airplane for Beginners and Experts

joytriner mini planoYou’ll find how easy it could be to build a good rc airplane. This is an evolution of the project we made some time ago the Joytrainer, that airplane was big and cool, it was based on the Simple Storch by Flitetest, some people wanted to have a smaller version, also I thought it should be compatible with cheaper components, and so I did it. The new model is portable and simple to make.

Start by downloading the plans and printing them.

Technical data

4 channels: Ailerons, elevator, rudder and throttle.
Size: 1050 mm of wingspan and 720mm long.
Average maximum weight without battery: 560g – Maximum allowable weight with battery: 860g.

List of materials and tools

You need some inexpensive tools and materials, that is the magic of this model aircraft, the materials and components are very cheap and not so complicated to find.

Materials and Tools:
  • For the construction use 2 sheets of foam board of 5mm, size A1, or 3 sheets of size A2, you can use a similar material such as XPS foam.
  • 2-3 mm thick plywood.
  • Recommended glue: Hot glue gun. Other glues work too, avoid using aggressive adhesives with foam such as CA.
  • Sharp hobby knife.
  • Pliers and wire cutters.
  • Landing gear: 1 – 2mm steel wire and wheels from 50mm to 80mm, you can buy a separate already made landing gear.
  • Soldering iron and tin.
  • Ruler (preferably metallic).
  • Paint and elements to decorate your model plane.
Electronic Components:
  • 2206 or similar motor with 1600KV – 2600KV.
  • 5 “- 7” propeller (use the one recommended by the motor manufacturer).
  • Recommended battery for beginners and stable flights: 2S from 2200 – 4000 mAh. (Do not fly on windy days with this configuration). For more power: 3S from 1500 – 3200 mAh. (You can fly on a bit windy days and do maneuvers).
  • X4 micro servos.
  • ESC of 30A with BEC.
  • Radio and receiver of a minimum of 4 channels.
  • X4 20 cm servo extensions.
  • Connectors you’re going to be using (if needed).
Links to products

Here’s a list of links to banggood.com but you can buy them in your favorite local store.

  1. Motor Racerstar
  2. ESC 30A and the alternative ESC de 30A Volantex
  3. 7″ prop or 6″ prop
  4. Radio that I recommend, and receiver. Another alternative.
  5. 3S battery or 2S battery. (Buy them from local stores).
  6. Lipo battery charger.
  7. X4 microservos. (You’ll need 2 more if you intend to use flaps).
  8. X2 70mm wheels and oneof 26mm.
  9. X2 servo extensions of 15cm. and X2 of 30 cm.
  10. Control horns.

    Hi friend I am back to your course I hope you remember me, I am struggling with making an RC plane, let me explain how, first of all I read about aerodynamics, like how an RC plane should be designed, I came to know about certain parameters, it says your chord length is 6 times your wing span means if it’s 6 then wing should be 36inch long (span), similarly fuselage length is 75% of wing span etc and like H stabilizer is 25% of wing area etc etc, now when I compare it with your previous made styrofoam plane, that you made outta fridge as you mentioned and when I look at the planes you shared I am hell confused, your H stabilizer is 35 cm = 9 inch, while your V stabilizer is 15 cm x 20cm or 6inch x 7inch, while your H stabilizer is no where achievenig 3:1 aspect ratio, can you please correct me on it

    I wish and hope you make something similar of styrofoam and explain it with the aerodynamics like aspect ratio etc like I mentioned above, you made that styrofoam plane wonderfully but left folks like me with only thoughts like a copycat, I thought to make dihedral wing over your made plane by making it 3 channel but when it comes to dimensions it’s confusion in your dimensions vs the dimensions rule of RC plane, I hope you got what I mean

      Hi, yes the books will always say something but the sky is the limit, it is correct to make the measurements as you’re saying because you read it on the book, it will be better and more stable, I don’t follow mathematical ratios, I just make adjustments based on experiences that I had with previous planes, but you gave me an idea for the next course, of course it will take some time to produce because I also need to take a look at the proper theory, and I’ll contrast it with the way I make my airplanes. It’s a good project to establish a good base for understanding the design and aerodynamics of airplanes.

    Actually I posted on two blogs one here and other on that styrofoam RC plane blog , oh yeah I would request you to make similar styrofoam RC plane as it’s easily available and really cheap and then you can explain it with aerodynamics rule and you can also suggest your students about the modification they can do on it like I said my plan was to make it 3 channel just by using dihedral rather than alerons etc so I bet you will be famous than anybody else , I bought insulation pink board of 20mm and I was never able to cut it perfect, even after using expensive paper cutters etc one side was straight while other comes weird , while getting 1inch thermocol aka styrofoam sheet was kinda easy to cut but till fuselage 20mm is ok, when you go for control surfaces you need 13mm or 0.5 inch styrofoam as getting bavel cuts is almost impossible with styrofoam of 1inch thickness, I almost got everything but being addicted to rules and regulations I can’t get it right which left me to one choice and that is copycat lol, when ever I try to redesign I get stuck but I am not giving up šŸ™‚

    Hi friend, hope you are doing well and happy new year, I am struggling in making dihedral wing neither with styrofoam nor with foam board 5mm sheets, would you please make a short video to show us how to make dihedral wing

      Hi, the dihedral is made naturally with the small spar included in the plan, and when you glue the wing use the dihedral gauge at the tips to give it the right angle.

    Hi when making dihedral you know when you make a wing aerodynamics aka Clark Y airfoail shape the problem is let’s say you get two pieces of airfoail Clark y let’s say 15inch each or let’s say making 42 inch wing by joining liner two 11 inches wing parts while liner it’s ok, when you further join 10inch left and right part to make it dihedral if even you use guage, the wings don’t fit right, you see big separation at the trailing and leading edges means not joining with the liner parts, now some how you beval them still on top they join while at the opposite back side you again see the clearly separation between wings I hope you get an idea what I am trying to say, so I hope in your glider video you can show us how to do it
