Thanks Chuck and Ian for your replys.

I think my concern about the bellcranks arise from my Brian Taylor Tempest. They didn't work out (or I didn't work them out...) and I chose to exclude the flaps. But now everything is larger so I'll probably go for the bellcranks with use of ball links and a large single servo. (Listen to the designer [sm=wink.gif]!!)
Read the review in SRCI on Skyshark's Avenger where they first used Y-pushrods and got uneven moments and lots of play. No, I'll go for the bellcranks!
