prgonzalez has discussed the big picture issues, and I think he's got it right.

HOWEVER: if you want a straightforward suggestion for a first kit build, I like the SIG 4-Star 60. It is a typical SIG construction, the parts fit very nicely together right out of the box (at least mine did), the plans and instructions are crystal clear, and the plane is a very nice flyer. The design is also very easy to modify if you find you like kit-bashing.

Lots of people fly 4*60s with Saito 91s in them. When I built mine, I couldn't afford the extra $ for a 4-stroke so I put in a SuperTigre G75 which is also a very lovely engine in this plane.

[8D]I see over on the other thread that they are also fond of the 4*. It's nice to have one's opinion backed up
