Hi Zac, I have not tried the 180 size flatouts but just finished building the 370 size cap 580. It was much more difficult to build than I imagined, All these carbon rods etc etc. However the end result looks good and the test flying is today. I opted for the rimfire brushless motor and I do hope it flies like advertised. If you do go for the cub I would be interested to know how easy it was to build. PS I believe you are in the correct forum OR am I wrong ???
