RE: Any suggestions for securing landing gear for a Scat Cat?
Just a suggestion if you go with Flyboy's mounting is to install blind nuts 3 or 4 and to use nylon 6/32 or larger screws to mount the helical gear, in the event of any future hard landings the nylon screws will shear and help prevent belly tear-out. A few spares will be handy to keep with you aswell'
On foam cores with no or minimal spars, while building I use a peice of thin ac ply cut to a spar shape and epoxy glue the LG hardwood blocks to it at the fore sides, it adds strength and very slight weight. (I then sunggly fit assembly into wing)
Also on any foam repair where LG blocks have torn loose I will cut a peice of scrap foam larger than the LG block and tightly fit & glue back into wing, then reinstall the block or part that came loose as it was when built originally.
