1/10 scale setup problems

[rat350r]

I have been working on getting a couple 1/10 scale hydroplanes trimmed out for a while now. One is a Miss Thriftway U-60 and the second is a modern Miss PICO American Dream U-100. To date I have been through two Aquacraft 1800Kv motors and two older DYNM3835 1500Kv 6-pole motors. I am using SeaKing 120A ESC and two 6000mah 2S packs in series. I have been running Octura X447 two-blade prop and several smaller props trying to get the boat trimmed out.

After several outings, trying to get things setup all I am accomplishing is burning up motors. The best speed I have been able to get is in the mid-30s. From what I have been seeing that is quite slow. So my questions are,

What should a 1/10 scale hydro weigh RTR?

What depth and angle should the prop be? Prop strut exiting the bottom of the hull.

What should the CG be?

What size range and manufacturer are the preferred props?

Are the props heavily modified regarding cup and blade profile.

What are suggested motors 36mm 60mm can size?

What should the hull ride attitude be? I feel that my boats are running way to wet.

I know I have left out details so please feel free to ask any questions on my setups.
