Believe it or not, but I have been using a Tacon 160 (19X10 prop) on my Vanquish and had to set my throttle curve to a max of 65% to keep from having too much acceleration on the up lines. Granted, it is a heavy motor, but I still make weight, barely. Has lasted for two seasons and has been in three different Vanquishs. May not be a top line motor, but it also uses less amperage than my Q80 in my Episode. I actually prefer the Vanquish and Tacon blend to the Hacker in the Episode. Go with what you feel comfortable with. In addition, I usually increase the percentage on my throttle curve in windy conditions about 5% and it seems to compensate all right.
