its the Revell uss fletcher/chevallier kit yes
even with small electronics and motors its still hard to get the extra available weight to turn her into a combat model
my fletcher has 2 mabuchi 130's , a 9 grams digital servo and a agile v16 1:18 scale esc (about a square inch footprint) she uses 2 li-ions for power and a small 4 channel multiplex pico receiver, she also has 4 aaa as receiver battery.
as ballest a single dead li-ion cell was the perfect weight.
to turn her into a combat model would require a cannon,a solenoid or servo and poppet and a co2 system.. and this all can nt be heavier then say 350 grams
she would also need a pump.
if someone wants to ndo the calculations feel free but i doubt its possible.
concerning molding parts, some yes and i have already started looking at what parts .. i know i can copy the whaleboats and liferafts and turrets , maybe even the torpedo tubes but alot of the superstructure parts are to curved to mold
