3GX setup questons

[macarey]

Hi guys,

Few quick questions about setting up a 3GX:
1) Before setting up the 3GX unit ,on my transmitter (DX7s), under the heading “d/r – expo” do I need to make sure there is no expo set for aileron, elevator & rudder?
2) I have reverted back to Firmware 2.1 because on the newer Firmware my 3gx units (ive tried it on 2 separate helis,2 separate 3gx’s) always struggle to complete the A.Rev stage.
Basically when I tip heli from side to side it does NOT level itself, it just shift a little bit up and down, but nothing clear cut ( E.Rev is fine bytheway). When on firmware 2.1 its fine (heli levels itself). This happens on both my 3gx units.
I did decide to, foolishly, fly my heli with this A.Rev issue not sorted, it tipped over, expensive error, Doh! Anyone else had this issue?

Many thanks
