Prop protection foam frame

So here it is my final frame for tis project. I'll use this indoor frame to add features like altitude hold with IR sensors and wifi or bluetooth telemetry and flight control so that I don't need the analag RC transmitter and reciever any more.

This frame looks like rubish. And yes it is rubish. Unfortunatly I ran out of foam so I had to cut out small pieces from the previous frame en glue them all togheter with a lot of epoxy making it a little bit heavier. The total weight of this quad incl 1300mAh 2 cell lipo is 285gr.

setup:

- Brushless inrunner motor 1230 5300kv

- 3x2 inch props (motors mounted upside down)

- Blue Series 12a ESC

- 1300 mAh 2 cell lipo

- NanoWii flight controller

- Analog FM 40mhz RX/TX

how-to:
Cut 5 foam strips with dimensions 20x40x200mm
Cut 2 foam strips with dimensions 20x40x260mm
Cut 2 foam strips with dimensions 20x20x120mm
Glue these foam strips with epoxy
In the center I cut out some foam where I mount the 2s 1300mAh battery.
The motors are attached to the foam arms with normal tape.
The props are mounted directly on the motor shaft. These props have a 1mm hole. You need to enlarge this hole with a "1.4mm" drill. Then you can push the prop on to the motor shaft.

review
I kept the same PID settings from the previous H-Frame. But this frame was flying much better with these settings. Because the battery is mounted in the center this certenly improves the stability.

Something I'll have the tune before I'll experiment with the IR sensors is the yaw authority and control. In order to yaw the copter has to create to much difference between the CCW and CW motors (props) causing it to become unstable. I also need to check to smoothen the RC control because it is reacting quick agressive on small stick inputs.

Foam H-Frame

The flight test with the X frame showed that the set of chosen components is good for further development. The initial goal was to make a small frame with prop protection. I have first created a small micro H-frame without prop protection. Just to see if the flight controller board can handle this.

setup:

- Brushless inrunner motor 1230 5300kv

- 3x2 inch props

- Blue Series 12a ESC

- 800 mAh 2 cell lipo

- i86L flight controller

- Analog FM 40mhz RX/TX

how-to:
Cut 4 foam strips with dimensions 20x30x120mm
Glue these foam strips with epoxy
In the center I cut out some foam to allow all electronics to be connected
The motors are attached to the foam arms with normal tape.
The props are mounted directly on the motor shaft. These props have a 1mm hole. You need to enlarge this hole with a "1.4mm" drill. Then you can push the prop on to the motor shaft.



review
Because the NanoWii board was already oscilating with the previous 30cm x-frame and this H frame is half the size, I decided to lower the PID values before the first test flight. As you can see on the movie It still need some PID tuning to fly smooth. But fact is that again this setup on this small frame can fly. So up to the next challange...
