Looking good. Looks like you did the same as me and put little horizontal plates on top and bottom of your rudder as well.
@NickMyers yea removed single curved mag and added 1 +1.5 units semi straight, had to chop up the deck into more sections keeping both forward mounts for optional play.
@NickMyers also the rudder turned out like that as I was putting it together I thought I would try it with fins also added a rotating rangefinder on the y turret to show pump power.
