Filed notches in the fuselage skin on both sides of the landing gear attach points in order to fit the larger Grove landing gear attach-blocks.
Drilled the attach holes though the wear blocks on one side. I'll do the other one after I buy a new 7/16" cobalt drill bit. The one I have is not the best quality, and it dulled quickly while drilling through the 4130 steel.
The Grove gear requires filing notches in the skin for the outboard attach blocks.
The bottom hole was quite a struggle to drill with a crappy drill bit.
