Hey guys. I am a total noob to RC flight. Until FT, I was way to worried (and broke) to think about trying to learn how to fly a $100 (or more) RC plane. But now I have no problems tossing a dollar worth of foam into the air while my thumbs learn their way around the controls. I understand the prop numbering system. 8x4 means an 8 inch long prop that will move (theoretically) 4 inches forward for every revolution. My question is about the styles of props. What are the advantages and disadvantages or similarities and differences between an 8x4 slo fly and an 8x4 direct drive prop?? Is one better than another on the swapables?? Is one better than the other for a noob like me?? I built a nutball and had a few 30 second flights and broke a few props until it took a dirt nap from about 30 feet up. I have another nutball cut out and a FT flyer about 2/3 glued up but only one prop left. I am going to order some more but was wondering if I could/should order something different.
