i have several sizes of canards. Over time, I have figured out how fast they turn the rocket. The canards for this flight were my largest, but larger ones could be used if the rocket could be made stable. Canards in the center of the rocket could do roll, but not yaw/pitch. The force has to be away from the center of gravity to turn the rocket. A moving tail would be one way to do that, but it would be difficult I think.
@@Jiminaus50 When you say made stable are you referring to keeping the center of pressure behind the center of gravity when designing the rocket with canards? Thanks for your reply
@@daveyofave Yes, the canards move the center of pressure forward. The larger they are, the more compensation is required (either larger fins on the bottom or more weight on top). If you look closely, you can see that I add fin tabs to the bottom fins to move the CP back. I adjust the size of them for most flights.
How was the size of the canard fins determined? Would a movable tail be needed if the control fins are in the center of the rocket?
