- Many (read most) full size aircraft need positive recovery (ie. full
- opposite rudder, pop the stick forward) from a spin. The Stearman I used
- to fly
- needed it and it still took 3/4 of a turn to recover. The longer the
- spin was,
- the faster it spun. Although full size aircraft are more likely to have
- this tendency (because if their higher moments of inertia, I think) some
- models have the same tendency. I had a GP Kaos .40 the needed positive
- recovery and a friend of mine spun it into the ground because I didn't
- tell him this. A more rearward CG
- helps to contribute to this tendency.
