As Staale knows I have tested them too, they seem good, much better than Hitec, but saying nothing (I saw a smoked Hitec on friday in a jet-now with JR 8411)...even CARF are using them in the UF on elevator...no collision avoidance electronics in them though
I won't use them yet in a jet as I don't get a few hundred euros saving for a possible ruined day, in a several thousand euro model.
I've used 8411's for years and years and know where I am.
