I did learn by doing on those, Hans,,,,,,,,the Monogram 1/72 Tigercat kit
The first one, I added the nose weight, and filled in behind the engines,,,,,,I read at the time that was enough, so I followed that advice,,,,,,,that one was a "tail drifter",,,,,most of the time, it sat on the nosegear, but, everyyyy once in a while, it would be on its tail, like a real aircraft waiting for fuel,,,,,,,I drilled the nosewheel and screwed it down to a base,,,,,,,it wasn't one of the "fit in the set right here" aircraft, anyway
now, I fill up everywhere I can,,,,,,,and on that one model,,,,,,,I would like something finer to really pack it in there,,,,,,,especially if I get the Aoshima Tigercat, I have never worked with that molding,,,,,,I don't want to "relearn what the Monogram taught me"
I could just glue or screw down all models to a base, but, I made the shelves the base material,,,,,,I have to be able to move VF-132 and VF-137 apart in order to add the VA-135 Skyraider in between them, for example,,,,,,,I sure can't just Park each finished aircraft in its final slot on the shelves, lol
