Yup, I’m fast coming to the same conclusion, Gerry
As you know the Alpina, which has quickly become my favourite ‘large model,’ has a socket in it’s wing which the MS-X4 fits perfectly into.
I’ve found that the Hitech HS 82MG fit’s almost as well but is just a little bit loose. Nothing that a bit of packing won’t cure of course, but I thought I’d have a go at trying to find the original servos.
I’ve looked and looked but can’t find an ‘X4’ anywhere, so I guess I’ts gonna be an 82MG or nothing!
