I have used a 1.kk flight controller along with an Arduino Nano and an ultrasonic sensor to add the feature of altitude hold.

This project describes of a low-cost GPS data logger for RC planes. In a previous project I described how to build a GPS data logger.

This system can do a number of things for your rocket!

I wanted an additional analog control in FlightGear - nice, cheap and compact.

Add more fun to bottle rockets!

In a previous project I developed a GPS data logger for RC aircraft but I did not have feedback on the receiver. So I modified the prototype

To add the feature of Direction Control using the initial direction as a reference and applying a proportional controller.
