I think people are quite interested, I think its more a case of dealing with the additional weight and complexity of the system and is the trade off really worth it in the long run.
I am looking forward to hopefully seeing a counter rotation prop drive at the WC's in a couple of weeks, at which time I will better be able to evaluate if there is truly a "significant" advantage to going in that direction.

I am surprised at the apparent lack of interest in the counter rotating out runner motors for F3A.
Though I have very little to do with F3A, I fly quite a bit of full size acro. The forces emanating from a propeller are tremendous, even at the comparatively poor power to weight ratio of full size acro machines. Without the ability to feel the forces by the "seat of the pants" flying R/C acro, I often wonder how we manage to trim F3A planes so well.
