Hmm... my hanger has the following categories filled now;
pylon racer: Caudron C.460 x2
race wings: Arrow and FPVWRA Spec Wing
night flyer: Eluminator wing
combat foamies: Das Little Stick & Baby Baron & Baby Brit
balsa sport planes: EVA Sport & Ugly Stick
3D plane: Enigma
float plane: Mini Drake 2
race quad: Wizard
indoor quad: Inductrix FPV
a handful of little indoor balsa planes: about 6 on the wall I think, which might be a little overkill, but they're like potato chips I've got about 3 more indoor kits too.
I've got plans and kits to fill out these categories;
a canard: Tiny Trainer conversion still needs debugging
a really really fast balsa wing: Cuda kit to assemble
a big balsa floater: FREDe kit to assemble
a cartoonish silly plane: NuB2 kit to assemble - going w/ a P-40 Flying Tiger look
a golden age balsa bird: Retro eMoth kit to assemble
a big golden age racer: have a 60" Gee Bee R3 fuselage, plans, and a pile of sticks
a glider: picking up a Spinster DLG at FF, and have a balsa 1.5 meter to restore
a 2s micro quad: Gremlin kit to assemble
I also want to get the bugs worked out of the Caudron C.460 golden age racer design and then start designing a fantasy bipe drawn by the same Italian designer who did the Gee Bee R3 concept.
But I also have about 8 other plane kits (foam and balsa), a pile of balsa sticks and some rolled plans, and a whole lot of bookmarked DTFB designs that I'm really looking forward to working on. My list of planes to build is a good bit longer than the completed ones, and has been every since I got back into the hobby.
But I don't know that I want to keep a plane in all of these categories - getting something to fly for a season, enjoying it at the field 3 or 4 times, and then letting it move on to a new home is just fine by me.
For me the dream is less about what's in the hanger right now, or having any specific planes, and more about having a workbench of building projects and regular swap meets where I can sell off a couple airframes every spring and fall.
