Do you have wing lockers ?
I purchased the locker kit when I ordered my QBK but intend to wait til later on to install them. I wonder how much "weakness" they will put in my wing structure..??..
What do you think about installing them in the last outboard section near the wing tips ??? That way the stress is not in the critical areas.......

The lockers aren't going to weaken the wings. They have been installed in many 601s and the design is blessed if not designed by CH. Moving them outward though is probably not a good idea because the moment of the weight will move out there as well and 30 lbs where they are designed would equal a greater weight further away from the center of gravity.

BTW... It will be much easier to install them during the building of the wing than waiting.

You definitely DO NOT want to move the wing lockers outboard. As Gig said the moment will be such that they will only be usable for very small amounts of weight.
I don't see any problem with installing the compartments at a later date unless you paint the plane. Then cutting and drilling will screw up the paint job.
I am installing dual baggage and dual landing lights just because they look cool.

Wings lockers can involve a lot of "fiddling and filing" when you install them but I think the end result is worthwhile. I like the fact that they are closer to the CG than the other baggage area. I agree that you do not want to move them further out on the wing As far as strength is concerned, I do not believe there is any net loss. The addition of the rear bulkhead may actually beef the wing up a little.

You could install them later but do you really want to drill out all those rivets in the spar and ribs in order to install the hinge and Dzus strips (not to mention installing the rear baggage bulkhead). It is so much easier to deburr holes and insure a clean install when you can disassemble the pieces and prep them prior to final assembly. I suggest that you'll be happier with the result if you make the decision now rather than put it off.

Good luck!

Tim
