Hello, I'm building my new powerlines edge and I will be putting a saito 100 in it now after i saw one fly this weeken at a club. I didn't get a chance to ask what size prop to put on it. The plane will be about 5 to 6 lbs dry. anyone have ideas on what size prop to put?

Apc 15/6 or 15/4W

I run 15-4w on my 91 saito. I'd put a 16-4W on a SA100.

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.
