[NSRCA-discussion] Mo'CF gear talk from AeroSlave

[Keith Black]

To Earl's point regarding the gear plate flexing and the benefits of the single piece gear, here's an interesting suggestion that was sent from Oxai with my Beryll. Apparently there were some problems with plate flexing and Naruke began using a carbon "strap" between the two halves of the gear. This should stop (or reduce) the tendency of the gear to want to pull away from each other in the center and flex the gear plate.

To add to this, the plate should be strong enough so as to not flex - all 
the flexing should be in the gear. When the plate flexes, bending forces are 
applied to its attachment point(s) to the fuse - this is really bad for 
composite fuse structure. The simple way to check for plate flex is to grasp 
the gear near the wheels and apply pressure up and out - similar to 
experienced in landing (the more forcefully you land the more you should 
flex the gear) and watch the plate for flex. Pretty much all plate materials 
will flex in a wide fuse. The easy fix is to make the plate into a "T" or 
"U" (channel) by adding a 1/8 x 1/4 carbon bar(s) across the plate, but 
other materials will also work.
