Oh eddy,
just my honest opinion, but C140ex performance condensed into a smaller package that you can put significantly cheaper Pro set-up in sounds like a very inviting prospect to me, and would imagine even more so to people who want a C140ex, but cant afford it. Would probably make a better back-up model for a 140ex than the little c50 also.
Only other competition it has are the Adrenaline and Synergy, both of which are ARTFs, which i for one dont really like.
I however will reserve judgement until i see one flying better than the C50. A big improvement in prop hang stability and all-round precision over the C50 would have me saving.
