This page is a repository for posts regarding the development of a servo-driven ornithopter. These posts were originally made on rcgroups.com and this page is meant to organize them in chronological order.

I. Servo prototype

  1. the build begins! - Part 1

  2. the build begins! - Part 2

II. Underpowered servos

  1. New frame and servo horns

  2. Wing build

  3. Covering the wing

  4. Completed wings and mounted electronics

  5. Glide tests

  6. Longer tail boom and additional spring

  7. Wiring electronics

  8. Arduino Code

  9. Powered test flights

  10. Adding low voltage cutoff

  11. Initial experiment with springs

  12. Current experiment #2

  13. Direct and indirect drive

III. Succesful design

  1. Constructing the fuselage

  2. Adding electronics and Tail

  3. Membrane wings inspired on Hang glider Sail

  4. Composite Foam-Fabric wings

  5. Adding tail servos

  6. Unsuccesful flight…

  7. Experiments with wing articulation

  8. Initial test with segmented wings

  9. Measured oscillations - Updated Servo controller code - servoMotor Library

  10. Brushless servos with extended wings and larger tail

  11. Lower frequency with brushless servos

  12. Successful flight - Flight controller with truncated triangle wave

  13. Modified Wings - Worsened Performance
