Just so there are no surprises that plane should be at least 6 pounds if it's like all the other ones I've heard of. Mine was 6 pounds 1.5 ounces with a 17 ounce YS63. With the Saito 100 it will be more like 6 pounds, 6 ounces. Don't get me wrong, it'll fly great but this ARF could stand a weight reduction IMO (for 3D that is, for IMAC it's fine). For $150 it's a steal.
With that engine you will probably end up putting the battery right behind the tank. With mine I had to tie wrap it to the engine box to get it to the recommended CG (94 mm. Right on the wing tube is close). I also had my tank on the CG so I lost a little nose weight.
