A nice plane, but not acrobatic in my opinion. It is a floater and high speed flight is not its forte. I like to fly it scale like and do touch and goes. Leave the wild stunts to a wing with less dihedral (sp). The stock control horns work ok for this, I strenthened the wood with ca wicked into pin holes thruout the area and have had no problems for 4 years and many flights with YS 91. You will enjoy this fine plane I think but again its not that areobatic.. Cuda
