    Hey Guys,
    Just thought I'd post a picture of my seats....

    They ended up pretty light , very strong , and comfortable...

    I bought them from "JEGS".... you can pick the color of

    the Bucket seat and of the Upholstered Cover

    They were too wide , first thing was to make them "Fit"

    After , I put lightening holes in them...

    Each seat W/cover weighs 9 lbs

    More info is at Wings Forum - Wittman section...

    I would proof-load them to about 6 G, just to make sure.

    I think the 6 G would be a very hard landing. Seat not breaking away from mount. No need for 23 Gs airline crash load.

    If they're a racing seat they should be strong enough. What are they made of?

    The FAA changes the FAR 23 requirements for certified airplanes a few years ago. Seats for light airplanes mow have to withstand 26G. Seems silly, and the seats in the new Cessnas weigh about three times what the old ones did. Seems that the old seats caused considerable injury just by breaking up in a crash. I would prefer a controlled-crush design as Fairchild built for some years, and those saved more than a few spines from compression injuries. We've been building cars with controlled-crush bodies for 30 years but we "improve" aircraft seats by making them as strong and rigid as concrete bridges. Dumb.

    Wow, this is an old thread. Four years later to reply to a critique to those seats. How are they working?

    Hey Mike, did you build in any provision to reposition the seats or do they bolt in one position only? I've been doing a mock up for a tailwind and would like to be able to reposition (as opposed to adjustable) mounting for the seats. Unbolt, add/subtract spacers, bolt back in. The reason is to provide proper seating for wider variety of pilots. Adjustable would be great but don't want the weight and complexity.

    The aluminium foam blocks seem a great alternative for a seat-mount, because they behave linear in a crash; doubling the energy absorption (or halving the highest load on your spine)

    Yes, they are adjustable.... Putting a Pillow behind you.... Moves you "Forward"...

    Putting one UNDER you... moves you "up"

    Otherwise , I made my Rudders "Adjustable"... ( Two positions )

    I'm making the plane to fit a taller person... ( Me )

    But just in case I ever decide to sell it....

    I have adjustment for a shorter person...

    The seats are re-leaved to fit over the Fuselage cross tube...

    and one channel holding it in place at the rear...

    It's not bolted in... but it will be held in place with a bunggie or something...

    My sleeping area needs the passenger seat to sit on the pilot seat...

    Great... linear...and absorbent... also halving ... wish I had an example of what your describing...

    especially aluminum foam...

    or you could delete this post and forget it ?
    .
    Since the seats fit as low as possible...

    Would you suggest raising them and losing Head room for a 6 ft 2 in Pilot...

    Or cutting the Structural Fuselage tubes in order to make room for these blocks...??

    Or was the idea even for this thread.... was it so we knew about this product on our next plane ?

    Since things are past suggestion... I'll leave the plane "As is".... But THANK YOU for all your knowlege

    about those blocks !
    .
    Gotta Fly... You be good...

    .PS Just a thought... You might wanna look up the spelling of Aluminum...
    Usually a red line under it is a "Hint"...
