i cant remember if futaba is positive or negitave.. I fly a JR. If someone else will chime in that has a futaba radio they can tell you wich way to go for softer feel.. I think its positive (like going from 40 to 60 would be softer) but dont take my word on it i havent had a futaba in over a year. some radios it would have to be a negative # like -40 to -60. but either way i think this would be all you need to get it dialed in to your "feel" that ou are looking for.
