Extended Fuel Tanks: Difference between revisions

By adding weight to the wings without reinforcing the involved structures, you are making use of the reserves built into the Van's original design.
Getting out of a developed spin requires the rudder to overcome the angular momentum of the spinning aircraft. The further any weight is from the center of rotation, the more its weight counts by the square of the distance (see Angular Momentum). For this reason, twin engine airplanes usually have a fin below the tailcone to resist spins. Adding weight to the wings without adding a fin bears the risk of not being able to recover from a developed spin.
