N1SPY's U3S built by 11 year old student who loves radio, science and space. Still needs GPS, power supply and antenna. This one may be too heavy to fly but seems like a great first step.

Nice shot, dear Ivan! I have a 8 years old son, Riccardo, that is interested in radio and he learned CW morse code. Now he is able to copy 8 WPM (Words Per Minute) and transmit up to 10 WPM. My best wishes for 11 years old student made his U3S! He is welcome on this forum, if he wants! We are here to create a community interested in small transmitter and balloons launches, but any other idea related to radio signals is welcome! Have a nice day!

Ivan,

You and your son are doing a great job on the U3s kit.Looks great,nice soldering !!

You mention it is too heavy to fly and wondered if you were planning to fly the entire U3s kit ?Here is a good simple method already posted on the forum here - http://radio-signals.com/forum/transmitting-payloads/

The U3s kit is a great tool for programming chips and testing.

Roberto is also in the process of using this method and hope this forum will help others.

Jim I think the only way this thing can fly is with a weather balloon and 20 cu. ft. of helium straight up to burst altitude. Tommy completed his U3S kit and posted a video here:

We will build a new scaled down kit later on for a balloon flight.
