Keep in mind that each blocks add weight to the plane. Secure them together with wooden pole or braces. Do not try to rotate the right side aerodynamic propellers, you have to flip them with F button. The different number of aerodynamic propeller will affect the number of propeller for stabilizer that will be addressed when I show you how to balance the lift later. While each wing add lift, you can just disregard it and purely aim for good looks here.

Aerodynamic propeller is even more compact and provide lift.Ĭreate your favorite wing shape with aerodynamic propellers. Wing panel is more compact, has good drag, and have many attachment points. Shape a wing with aerodynamic propeller block or wing panel block.Do not use wing block. When a plane gains speed from the thrust, the wings generate lift, which makes the plane fly. The force created by the engine is called thrust. Just remember, make sure each propeller is rotating in opposite direction relative to its counterpart. The torque will already be negated if you build a double rotor plane. However, this will halve the effectiveness of the rotor.Īdd another unpowered wheel or swivel joint on the front and brace it.It will secure the rotor and reduce engine vibration when moving in high speed.Īdd flipped propellers on the opposite side.This will create coaxial counter-rotating engines and increases the effectiveness of the engine. 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.
