Melax, I think your speeds are very optimistic. Take off safety speed 65 kts agreed, climb is usually 70 kts. I am unaware of a Bn2 that will achieve 100 kts cruise climb - certainly not loaded to max payload. Vy is 75 kts. POH indicates 95 kts for a comfortable climb but at max weight I suspect the rate of climb will be bearly 100/200 fpm.
