Ok I agree with over kill in some cases I fly mainly 40-60 size stuff and can't say I have had any problems I thought would be fixed with digital
I have ds811's on a raptor I don't fly right now I might stick them in my magic 3d and see if I feel a difference
from what I have just been reading on the 2048 tx they let the servos repond faster to stick movements so I would think that your still getting better performance over analog
but the 2048 would give faster stick input to them my radio is faster then I am right now so I'll wait on that
