When you use one rotor your entire aircraft will also roll in the opposite direction.Īn unpowered wheel or swivel joint will usually solve the problem of aircraft rolling on their own, Test it in zero-g to make sure it goes forward properly.Īdd plane body with unpowered wheel or swivel joint.Keep in mind about Newton's third law of motion: For every action there is an equal and opposite reaction. While their lift is the same, the longer one has higher linear velocity, so it will generate more thrust.

Use more engine if you want to go faster.Īdd one block, add a propeller on each sides, then replace that block with a wheel.How to bypass the intersection warning: /EvenValidCoatiĮDIT: or you can just use Advanced Building Tools Make sure they don’t spin too fast or the propellers will be stretched and the wheel will start spasming.

Place four or more wheels on the starting block. Wheel with propeller is one of the easiest source of thrust to build.
