hi, glad i could be at help...

well, if the instruction manual gives u low and hi rates, then the low rates will be fine, if it doesnt give u low rates, then make it as low as u want, but just in case use dual rates and make the hi rates a little bit more sensitive... control trows are not that important...

but a forward recomended cg may be a lot of help to begin with...

just go out there and fly, enjoy and i think that by the end of the day, u may will had increased the control trows of low rates already...

i set my low rates as hi as i still feel confortable for landing or doing presicion pattern stuff.. on hi rates i have it at max...
for example in my funtana i use 40 degrees in elev in hi rates, but in low, im at 25 degrees , thats a lot for low rates... everyone will have diferent setting depending on how confortable u feel....

have fun..
