It probably takes more skill to set your plane up to function properly with these little devices than it it does to fly with out them.. I have only flowen a Nexstar with an auto pilot installed in it and I found it harder to fly so I could see if a person didn't know what they were doing possibly these little stabilizer things might fight you for control and make it harder to fly .. I think its like anything else , if somebody wants to explore that aspect of the hobby then let them explore it.. This hobby is big enough for us all and we dont all need to be doing the same things.. Maybe when I need the use of some of these things( and this could be soon) the path will be paved and I will not need to know everything there is to know about them , I will just need to know where to look to find out what I need to know..So thank goodness for the guys that are playing with them..
