Wow! Yet another tremendous amount of info for a noob to absorb! :-)
My VQ has an 82" wing and is 1/7.5'ish scale. I'm expecting 18lbs. Wing loading of 49oz/sq ft.
I don't know the net affect of going from a 16x8 to a 15.75x13 will be. Knocking-off 1/4" at the tip of a 16" arc is a fair amount of "swept area"(?). Can an eflite 90/Castle Ice 100/6s 5000mah combo swing it?
Unloaded rpm on 6s would be 8190. 90% of that would be 7371. What pitch would I need to get it into the 90-100mph range? I ask because my VQ FW-190 flew very nicely at 85mph... with 35oz/sq ft wing loading.
