Subject: RE: Pietenpol-List: Seat back ply...structural?Mike--- do NOT REMOVE THE plywood that the seat makes up--- this is a former inthe fuselage ! Keeps things square-- just like a rubber band modelairplane when the torque from the rubber band wants to twist the daylights outof the fuselage---keep the plywood. Okay-- you have all of my photos. You've seen my airplane. I have a fold-downseat BUT I FRAMED IN THE SEAT with poplar all the way around veryheavily to keep that reinforcement going and you should too. Don't mess withsomething so viably structural (tho I did !) and keep the integritygoing back to the tail. The last thing you want is for your tail to twist off at the back side of yourbutt in flight when you hit some severe CAT ! (Clear air turbulence) Don't be so worried about saving weight like this as to jepordize your safety man!!!!!!Build to the plans-- modify to suit but don't be doing things so radical such asleaving out the back seat former !Mike C.PS-- even with what I did I STILL came out at 632 pounds empty weight-- which isconsidered pretty light for a 3-pce wing Piet. Don't skimp on your life tosave 1.2 pounds !!!!!!!!!!!!!!!________________________________________________________________________________Date: Sun, 13 Sep 2009 20:56:29 -0500Subject: Re: Pietenpol-List: yep--it's a little bit dated--Mike Cuy's DVD is stillavailable
