Mine pitches very strongly to the belly with big rudder inputs, but with small inputs it's pretty neutral. It'll hold a knife edge from horizon to horizon with very little rudder input, but a knife edge loop gets exciting when I crank the rudder in coming down the back half.

4.5 lbs with a 61? Mine's a little over 5 lbs with an Irvine 53. Next time I buy an ARF I'm gonna weigh all the boxes at the shop and buy the lightest one.
