Yeah...I'm a plane builder too. Got a 1/4 scale J3 of mine on display at a 
local aviation museum and a 1/3 scale J3 under construction (has been for 
several years...I'm a rather slow builder :-)) I subscribe to SCALE RC 
MODELER but I find it a bit shallow.

It's not just a matter of working in tight spaces. It's also a problem of 
what has to be stuffed in those tight spaces. Submarines are trimmed by the 
addition of lead in the keel and foam in the upper hull. In addtion, your 
radio and running gear will be in a waterproof box. So, in a 4" wide hull 
you'll have less than 3" of space in your waterproof box and less than 1" of 
space for your ballast and counter ballast. It certainly can be done but I 
wouldn't enjoy it. Another MAJOR consideration is the battery capacity 
available in a small hull. My (fat) 63" SCORPION could carry a 7.5 ah battery 
that would last for hours. My good friend Matt has a (skinny) 63" Type IX 
U-boat that will only hold a 1800 mah battery that lasts about 20 minutes.
