Well in my (limited) experience with a T-tail arrow
Even after reaching Vr u still need a scary lot of force to pull the stick back and eventually get the nose off the ground. For a second I was wondering if I messed up to read the airspeed indicator! To me it feels like the Arrow just doesn't want to leave the ground and even on the first seconds of initial climb-out the stick needs brutal force (compared to others) to keep the nose where u want it ... any other C182 or TB20 would have stalled within seconds if u'd pulled the stick like that
However i don't have experience on a Cherokee or any other P28 so i can't compare it to that...
