RE: slow stick prop choices versus flight performance
Generally the diameter, the first number, gives you thrust and the pitch, the second number gives you speed. So the 1047 will be give the least thrust and the least speed but will also pull the least amps. The 1260 will give the greatest thrust but be slower than the 1180. The 1180 will give the fastest speed but will have a lower thrust than the 1260. Slow Stick needs thrust not speed, forget the 1047.
