Guys,
I've installed a Phoenix Ice 50 in my model and here is a screen shot of the first full pattern. I replaced the 12x6 with a 12x4.5 pusher(13x4.5 cut down). RPM is set at 9400. I also went to 60' .015 braided instead of the 64' x .012 solids I was using. Solids are too much of a headache...Lap times are still around 5.3 seconds.
After one flight, i'm pretty happy with the results.
The Ice 50 is a bit of overkill. The phoenix 35 will go back into this model and the Ice 50 will go into my new model that will be larger, heavier, and significantly more power.
