just to stir up some thoughts....

.
1.low rates... for the first flight you might NEED those high rates if you have a trim problem... yes i almost did crash a plane by having high rates, a bank turned into 2 rolls!!! but i test fly all planes on high rate. however i dont move the stick much, years of RC car racing.
2. i have a friend that learnt on low rates, now he cant fly on high, his Cougar is wasted on him
3. some learners ( like my GF on a glider ) loose concentration when the plane is too slow to respond/ feels remote to them then get into trouble easy, i moved the horns in a notch ( not mad, but below what i would have ) and suddenly shes much better. the twitcher glider needs more thought and demands they pay attention. its also damn nice for me to fly low over the grass tufts now
