Intro: RC Plane DIY Flaps Control System
I have always wanted to create my own RC plane, but creating it involves many steps. I decided to start by creating the motion system on the plane, which would allow me to hook up the motors used in this directly to the control system (in which I plan to use an Arduino) This is very basic, and allows for even those who aren't tech geeks, and can't afford materials, to create something very similar, along these lines.
1. Dental Rubber Bands (used for braces), found at CVS, or here
2. Wing System (see plans at Step 1)
3. Flaps System (see plans at Step 1)
4. Fishing Wire found here (but can be cheaper)
5. Piano Wire
6. Some super glue form (I used krazy glue)
Step 1: The Stabilizer, Wing Design
All of these should be designed specifically to incorporate the wings you want. I am using simple balsa wings, and stabilizers with small rectangles in order to achieve light weight, and a nice, loose fit for the moving parts.
Through the locations of the flap placement, attach a piano wire, from one end of the hole to the other (see picture, in red). This will be the location of the hinge of the flaps and rudders will be placed in. This can be placed atop the wing structure, and ensure proper gluing of the wire. I used krazy glue, but it is your choice.
Step 2: Flaps Attached!
Create 2 small circular hinges (see image) per flap using the piano wire, and glue them onto the flaps, not after hooking them onto the piano wire though. This will enable the flap to easily move when you need it to. Now I suppose you are assuming how the system will keep straight. This is when the rubber bands come into play. Create four hooks per flap and attach two to either side of the flap and two to either side of the wing/stabilizer.
Step 3: Final Step! Connection!
After also attaching strings to the hooks on the flaps, tie those hooks to the servos. I attached the 2 strings from the rudder to one servo (either one way or other), but for the other flaps, each flap got it's own servo, so that it could be controlled individually. After, some next steps for a plane builder would be to build the body of the plane, if not already complete.
This is my 1st instructable, and thanks for reading. Please don't forget to vote for my project in 'Move It' and 'Things that Fly'. Thank you.
