It has been a few weeks since our last Guess the GBC. But it is back. In this series we want to test your knowledge on our GBCs and GBCs in general. In this video you can see a mechanism controlling 3 pneumatic valves automatically. Optionally the builder can also manually control the valves. Do you know from which of our GBCs this may be?
If you know the answer, leave a comment down below. The answer will be given in the next Guess the GBC.
The Guess the GBC #14 from last week was our Shooter Module from our GBC 52 Flight Fair. The builder can adjust the tension of the rubber band to have some fine control over the output power.
