Check out the new trailer done by my 9 year old son Jonah :)
All the STL files for 3D printing can be found here:
The Coast Guard Rescue Ship is also ready to print:
Here is a video of the prototype:
Here is one of the final version flying:
Closer View of Lift off:
To wire and build the pivoting dome, solder at least 18ga wire to 2 of the terminals on the male microphone plug. Then fill the hole with epoxy to assure the wires nor plug will twist out.
Here is a schematic that should work well....
Assemble the pivoting motor and audio jack as shown below. The latest STL files on Thingiverse are a little different than the prototype pictures shown here:
The spring helped with oscillations while flying.
Wire the controller potentiometer as shown below:
Use a rubber band to make the throttle handle on the left always move back to 0 speed if the handle is let go.
Wire the 2 pots to A0 for throttle and A1 for Forward/Reverse.
Put the helicopter motor together and glue the chopper together:
Start putting it all together...
I am working on the next phase now. This is the one I had as a kid :)
