I have a WH Edge 84" with a DA 50 on it. I also have several planes including a few that have a 72" wingspan. I only bring the smaller planes to the field with me in case I should have problems with the larger one. Guess what. The smaller planes have been gathering dust. The 84" plane flies so much better and more realistic and have much better presence in the air. I would like to sell all my smaller planes but would not get my money out of them. I am presently putting together a 87" Yak. The WH Edge is a great plane and built well. Do yourself a favor and get the 84" Edge with the 366 or a 50 size engine (50 is plenty 60 is a rocket). To tell you the truth I think we all worry about the landing gear and breaking props. I did not bend my gear at all this year and did not break any props. It may have been a matter of luck but it was well worth the chance........ My nickels worth......
