35 cm and EZB are about pushing the limits. The moment you add a minimum weight, you've kinda ended the point of the event.

We already have an EZB event for those who don't like wood selection to reach the point of insane--F1L. I've said before that if you put a minimum weight on EZB, one of those two classes will die the death.

35 cm has been reasonably popular in general...let's leave it alone.

Now let's get back to the topic. That dragonfly is some amazing engineering. What kind of control system are they using on it?
