We are a TARC team working on a rocket with actively controlled fins. Before moving the fins, we just set them to 10 degrees in opposite ways (hopefully creating a roll) and flew it.
In the first launch (where its more sunny) we had relatively weak servos so we thought that was why it wasn't flying vertical. For the next one we bought Bluebird BMS-115WV+ servos which we are confident are strong enough, but its still doing something similar.
Our OpenRocket sim says it should fly 826ft and it has a good stability.
However, here are the actual stats we got:
- Flight 1: 459ft
- Flight 2: 547ft
Both are not vertical like OpenRocket predicted.
Here is an image of our payload:
On the launches we put masking around the slit that the fins slide in through.
We are flying on a F51-10NT from Aerotech.
