RE: Demoiselle Plans?
After watching that Vid I'm ready to try it again! My 1st one came off the Carsten Plans. I Was always bothered about the tail rigging geometry and bell crank arrangements'.,as it seems the cable drive and the articulated tail always gave me too much differential Looseness ? Either I'd get the elevator the way I liked it , the the rudder cabling was too loose or vice verse.
Any tip's on how you over came the quad pull / pull geometry ? Did you use idler sheaves on the mast ?

Jack.... I took these to see if my controls may give you ideas.
I did not like mine when the elevator wires were attached to the forward tips... I drilled holes 1/2 way back towards the center post, epoxied in nylon tubes and connected there with a large loop. It now has decent rudder travel with little effect on elevator.
Also slipped some black cloth behind the rudder controls so a pic of some kind would show up. This setup allows for elevator control with little effect to the rudder.
Mine was flying using 140# Kevlar string... It kind of bothered me as it is very strong but not all that abrasion resistant. I changed the controls to thin steel cable this winter. It is a big model and I feel better with the steel lines. U-Control uses this type cable on there airplanes so it is easily available.
Hope this helps..Randy

I might have something that can help. Send me a private message with your e-mail and I will contact you that way.
What I can say is that Alien aircraft sold out many years ago. I believe that SIG bought their kit line as they produced their airplanes for some time. I think they may still be listed on the SIG web site, but as no stock. There has been at least 2 owners of SIG since then. Currently the plant in Iowa is cleaned out and for sale, hopefully to open again in some form.. I heard rumors of Illinois.
I still have my Demoiselle, Love it.
