I´ll get an ARF ACE Seamaster to be used only on water. Ordering also a Satio .72 for it.

Is a 3 blade prop 12-6 the rec. one?

Will that size of eng require some reinforcements to the kit?

What hardware included in the kit shall I replace due to low quality? What should I replace it with?

Understand I need to reinforce the horizontal Stab, one flying wire each side enough?
Use full lenght velcro/servo tape for the small tip floats, use a golden rod for the elevator, or for all included rods? I must be missing many other things, could you help to continue my list?

Ahhh Tip floats... Remember reading to deflect them lat. some 5 deg. Which way? Front closer to the fuselage or the other way around? Any experience with that?

Many Tks.
