Plane is very light to start with, it wont be a problem to get Under 6lb.
do a search on here for the Magic Formula, I posted a pic and all the individual component weights
of it last year.
only thing I changed, was the OEM piano wire Pull pull system, bit heavy
just changed is for a SS wire pull pull system.
Going with a saito 82 would save 4 oz off my weight, CG might become an issue though.
You need 6 servos for the plane 2 on elevator.
