Bterry, having never installed either type, I think the RDS would be easer to install, and would be less visable. Ican't imigane trying to cover the plane with the durant direct drives. Changing a serov would require the removal of the control surface. These are just my observations from looking at the site. Seems that one of the model magazines ran a How To on a similuar setup in the last year or two. One of the negatives was the bulge in the surface for the servo. With the RDS, the servo can be moved back to the fat part of the wing or elevator. I'm not sure Iwould use them on the rudder, but given enough meet in the rudder, it may be possible. The Laser 2000 only has a 3/8" thick rudder and elevator. Tying to hide servos in it woudn't be easy for either system.

Thanks for the link anyway.
