* 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. | * 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 a weight is from the center of rotation, the more its weight counts by the square of the distance (see [https://en.wikipedia.org/wiki/Angular_momentum 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. | * Getting out of a developed spin requires the rudder to overcome the angular momentum of the spinning aircraft. The further a weight is from the center of rotation, the more its weight counts by the square of the distance (see [https://en.wikipedia.org/wiki/Angular_momentum Angular Momentum]). For this reason, twin engine airplanes usually have large rudders and / or a fin below the tailcone to resist spins. Adding weight to the wings without adding a larger rudder of a fin bears the risk of not being able to recover from a developed spin. | ||
