Default RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Hi,

I'm just curious - do You think the advantage with contra rotation props is so big that top fliers need to use it to be able to stay at the top?
This unit is a very nice thing and it looks so cool and seems to be some clear advantages but the added cost of $1200-1300 (for Brenner's unit) will not help to broaden the base of people want to get more serious into F3A flying I'm afraid. But maybe there will be more manufacturers of contra rotationg props units in the future and cost will hopefully get down a little.
The spinner/props looks rather fragile and a light prop strike is out of the question I suppose.

Anyone know what contra rotation props unit Sebastiano Silvestri use on his Wind S Pro ''all composite'', seen in the picture in link below:
