Default RE: GP Viper 500 - flight report

This weekend I will test it with this prop 9 1/2" x 7.5NN. I order it yesterday.

Yesterday, I try my little OS.46 with Wildcat 18% oil / 30% nitro an a cold plug. Wow! Finally I got all the power from my .46. I run at peak RPM (16 200) an APC 9.5X7. I make it rich a little to reduce the RPM to 15 800, for security. I saw the difference in the air... love that
