I have a few Spectrum 6030's in my Hawk, they seem very nice, they are on flaps, rudder, steering. But when I recently went to buy more for my UF I see they are discontinued already. That is one thing I hate about modern marketing, you can expect everything to change constantly. That is to me the single best reason to buy 8411's or 8711's, they have been proven and stayed around a long time. But I think in the future we may just be rolling "new" dice in every jet we build. At least it seem that way if you go with the new brands.
