I am thinking of getting this plane. I have heard alot of good things about the extra 300 46 size but not too much about the 61. I am planning on using a OS 91. Any tips and pros or cons welcome. I want to stay in the price range and size on this plane (150.00$@ Tower) if you have any other suggestions. I am looking to get into a plane with more 3D possibilities....Thanks, Tugboat.
