Welcome ! I'v been wanting to do a RC version of a Revell 1/72 sub for some time now. But I dont know a lot about the working parts to "sink " it in a controlled fashion. I know tons of ways to " BLAST" it with bottle rockets !
Please post pictures of your proggress. I too am thinking of doing an escourt carrier in 1/144. The hull will be about 5 feet long ! Specifically The USS Bouge CVE 9 I believe.
Have fun wandering in the forums..... there are no stupid questions. But the answers..........LOL
