Pftt pfttt excuse me while I spit out these feathers. I turned the prop around and it definitely worked better. I still need a flight test, but it was on backwards.
Sorry for my outburst but I thought I was get'n jerked around!

Now my question is what is the difference between a 5X5 and the suggested 6x4? I assume the first number is the diameter in inches and the next number has something to do with pitch??
