I agree with everything you say.I'm trying to hover in my house on carpet. Acually bring it up to about 2 feet and things get interesting. I try to hold a hover for about 5 to 6 seconds than let it down and sometimes to hard, thank you carpet. Do the extra flybar weights help? Was your swash plate ok from the company? Moving the servo linkages in one hole, do you mean the first hole? What do you think was your most important move? Can you hover ok now? Glad I have my CX2!!!!!
