Ok, to cut a long story short, I have had a backwards drift on my heli which has come and gone, lately it has been coming more than going, so I have just ordered an AR7200BX and am going to do a comparison. I am just a little tired of tweaking the 3GX all the time and checking my setup over and over. I don't know if there is a problem with my 3GX or my setup but if it's my set-up well then I can't find what is wrong with it so I'm just going to see if the beastx solves the problem and if it does I'll sell my 3GX on ebay. if it doesn't solve the problem then I will be very surprised and bite a piece of humble pie- send the heli to a ro to get it sorted once and for all. stay tuned, and watch this space.

Any update?

Yeah sorry about the delay. The AR7200BX solved the drift problem straight away. However I posted my 3GX back to align for repair/assessment and am still waiting to hear back from them. Not impressed with align on this issue, it has been months.

OK, I finally received a package from align today, and they have just replaced the unit with a new one, No explanation of what was wrong with it (not that I needed to be told) but I don't think I am going to put it back on my heli as I am fairly happy with the AR7200BX, the only problem with the BX is that if I give the heli sudden full collective the tail doesn't manage to hold the tail for about the first second or so which has nearly caused me to crash a couple of times. Although that might be my settings- not sure I will need to do some research when I have some time.

So to summarise briefly: I have received a new 3GX from Align and I can't tell you if it has solved the drift issue as I am not going to fit it until my next full service which will be in about 4o flights time.- "It ain't broke, so why fix it?" I will post again once I have refitted it. Cheers guys.
