Sig 4 star 60 Kit builds very easy and is a very good flyer, when you build only put 1/2 the diehedral the wing, and if you think you might like to fly with float's later add a support for rear mount for the float's while it is easy to do, plane would fly well with the 61 2 stoke, I fly mine with a YS91, and love (it unlimited vertical) these planes fly well in calm weather or windy condition's, are pretty aerobatic, (but not 3D) Also the horizon 60 stick is a good choice.

Good luck.
