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 unitis 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 baseof peoplewant 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 hisWind S Pro "all composite", seen in the picture in link below:
