i also have that yak and last year i had a saito 150 with a vess 17/6 prop on it, cg was slight down pressure inverted. the waterfalls were ok almost like what you described and i have about 50degree's elevator travel. this year the only thing i changed was the motor and prop. went with a mld 28 gasser and a vess 18/6 and the waterfalls were almost like it was on a pivot. i really believe the bigger prop made all the improvement. what motor and prop combo do you have?
