In my opinion have had 2 of these -one had over 100 flights on it intially with a os91 4stroke then a saito 100.Then on like the 101st flight I put it into a flatspin & it wouldnt recover that day..I then bought another 1 & put a irvine 61 on it and ohhh man this baby was ballistic..I sold that 1 and now got a WM 80inch Miss America to replace it.In my opinion if you want all out speed go with the 61 size 2stroke-namely a irvine-they are powerhouses

If you want a more scale sound and a plane thats almost as fast go with the Saito100..Either way I think you'll be happy.I fly mostly jets so anything under 130 now is basically boring to me - LOL

Also dont get that bumping around in flight as you do with proplanes..cuts thru 20 mph winds like butter-unaffected.Anyways I steered off topics course so good luck with your choice
