I'm on 3.04 now, but am considering downgrading for a little faster descent. AFAIK v2 allows faster descent, but not as fast as v1.08. Does anyone know the descent parameters of 1.08 and 2.0, as compared to 3.04 (or whatever the latest version is)??? Also, is it an easy process to downgrade? Just load the 1.08 or 2.0 assistant software, and hit "upgrade"??? Thanks..... BTW, I took off the prop guards, so a little faster descent shouldn't get me in trouble, plus the CF props seem to help also (debatable).
