I’ve made about 3 of these now. Basically it is a pc power supply that I have added banana jack connectors to and a push button reset switch. I use these power supplies for the 3d printers and to supply power to my RC battery charger.
Here is a 3D printed rocket made out of PLA. I designed it and printed it in sections. It has flow 3 times now and is in great shape. I used D size estes rocket motors.
Here is a video of the first test flight.
I decided to design a pan/tilt antenna tracker for FPV. I wanted to use standard servos. The servos are all geared using 3D printed gears. The pan axis uses a ballbearing supported gear to help reduce unwanted oscillation then pan is stopped. I was planning to use the Eagletree system but have since sold it and use the FY-31AP system from http://shop.fyetech.com/
Here are some videos and pictures of the system I built. I am posting this entry a long time after the build so it isn’t a play by play log like you’ll be seeing in future posts.
Here is a mount for a GWS ducted fan that I designed. It is designed to be mounted on a pylon. I have a brushless motor in this one and printed a pair for use in a yet to be designed airframe.
