I too built the 1/200 Hood with RC conversion last year.
I found the best upgrades to be the wooden deck and the metal gun barrels.
I also added a sound system and smokers.
Biggest problem - however careful I was, a visit to the pond always resulted in some form of damage, mainly to the railings and the antenna.
However, I thoroughly enjoyed the build and she really looks good on the water.
Have a great build
