I don't whom you were asking for sure but in my case, since I only want to fly IMAC "style" manuevers I only have one rate. The dual rate switches on my transmitter for this type plane do nothing. I only use them if I want to test out a higher or lower rate. I set them up temporarily to test out the new rates and once I decide which one to use I set high/med/low rates to be all the same. I do have another airplane or two where I have multiple rates or conditions but for my IMAC style aerobatic planes... one rate... "just enough".
