Differences between KR-407S and KR-408S receivers
#1
I wanna buy a spare receiver for my Helios but I don't know which of those two is better.
It seems that the older one KR-408S is much more expensive but KR-407S is newer and fully compatible with new technology. I think maybe there are some advantages of KR-408S that I don't know.
Hope you guys can help me
Thanks
