RE: Seagull Models Harrier 3D
A 180? Please...that's WAY more power than this agile performer needs. A 120 is a bit more than the average pilot will use, with this plane. I don't see any need to add weight just to have more power than you need. Of course if you add the weight, you'll need the power...hmmmm. The Saito 100 is a perfect match. Just my opinion.
