One of the problems with an Arrow is that the nose u/c extends forwards, i.e. against the slipstream. Altho' the POH says it will extend in emergency free fall at 87kts you may find you have to come down to 70 kts to make it work. What happens is that the slipstream retards the nose u/c but it is usually one of the main u/cs that doesn't lock down as a result of the forces on the nose leg.
