Iceman ... I hate you!!! Now I have to go out and buy another Viper ... she looks about as fast as my Viper on a TT46.
Thanks for your info, I still got 4S 2,500s to use.
I shall await your Turnigy 35-48-1100 motor run and see how she runs. The similar DualSky motor on their MotorCalc with a 9x9 on 4S shows 60+A. Pitch speed is 100 mph. Perhaps that can drop to about 55A in flight. Just nice for a 3 min flight. I wonder what would happen with 6S 2,500s since the plane would enjoy some extra weight up front?
See the chart below ... 40A ... 115 mph ... but I wonder if the thrust is sufficient? It will pull 60A with an 8x6 with a 110 mph pitch speed.
