My current plan is to mount and rig the flaps and ailerons so I can remove them until final assembly. In order to do this, I needed to mount the flap actuator weldment WD-806 and the electric motor. In order to do that, I needed to have the cabin floor installed, so I decided to install it permanently.
Some builders go to the trouble of installing nutplates in place of pull riveting the floors tp the ribs as called for in Vans plans. I decided not to do that and I guess I’ll see in the future whether that will turn out to be a mistake. I hear that installing all the nutplates is a real PITA. I’m all booked up on PITA projects, so I don’t need any more of them!
