BT-70 Whistle NoseCone

thingiverse

I wanted to make a fun rocket nose cone with a whistle built into it. I have a couple more designs im going to be trying out and i will make them in various sizes but this was my starting point. The only difference in the images shown and the model im uploading, is the bar at the base of the neck of the nose cone for the parachute and shock cord, i made it 4mm wide for strength (images were my first print which was 2mm wide) This did work just fine in its first flight but i wanted it to be a bit more resilient. Its definitely loud enough to hear over the motor and you can hear it screaming after the motor runs out and its still ascending. I'll attach a quick video, my recording device doesn't do it justice but you can see that it works.
