5s or 10s A123 setup for boat?

[nitrostarter]

Ok, let me rephrase my words.

A123's are ok in a boat. However, Quality high capacity lipo's are a must in Fast Electric Boating.

A Titan 29 would be a waste at speeds of 22mph... Buy Villian or Kyosho for that.
The Titan is a very capable boat and loves to run 40-45mph in light chop. I would run a 4s2p Lipo setup with a Feigao 10XL and a X445 prop and see low to mid 40's all day. Or maybe a 1515/1Y on 4s2p Lipos with a X442 of X640 and see 50's all day.
