What you say of Oxai is very true, they are amazing aircraft. However, having emailed Oxai Europe and US I have discovered that they will almost certainly
not offer this model with an anhedral tail. One of the main reasons I bought this model was specifically because of the anhedral tail. There have been a few rumours that the tail is a gimmick, maybe it is maybe it is'nt. All I know is, is that Naruke recommends the -5 degree tail as it "makes for easier rolling circles and loops and there is less coupling". Plus it looks dam cool as well

Therefore if you want an anhedral tail Astral XX you go for either Naruke Hobby or the X-Treme version. Otherwise, the Oxai may well be your number one choice.
Whatever version people choose they will all be amazing aircraft and of the highest quality. I think the comments about the X-Treme Astral being of C-ARF construction are inaccurate and sell it far short of the fantastic plane it is.

I paid a little extra and bought two stabs - 0 deg. and the -5 deg. stab... I want to see what the difference is.
