The CMP Zero is a real floater and slick. Mine was 11 pounds with a laser 120. I also had a OS 108 in it. It will fly well (scale) with a Saito 100 or OS 91fx. You might want to search for the many treads on it. A wide track is handy which the Zero or P-47 has. Most warbirds come out tail heavy so plan before to put everything as far forward as possible if it looks like a short nose moment. With some creative moving my GP PT-17 came in at 13 pounds using a Saito 120 and no lead. The plans called for 18 ounces of lead in a box. You don't have to put a big heavy motor in the front to balance most planes. Saying that I did have to put 2 pounds of lead in the front of my 83" Claude.
