I'm not too worried about the charging stuff. honestly, I'm a bit peeved the tx has no indicator that the battery is charging or that the battery is charged.
also, a bit more complicated, but the TX12 can support Spektrum and a few others via external modules. I'm not sure how much said modules would cost, but with the two battery system the TX12 won't suffer like the Jumper T8 Pro does, with it's single battery.
so, back to my original question...have there been revisions and should I watch out for anything in particular? not at you Brit, in general as it's an open question.
