I helped my dad finish a Dumas Windy boat that he started building. Most of the hull was built, and the tail/motor pod was partially completed. I finished the tail and motor pod, expoxied the entire boat, primed it, then painted it.

We decided to go electric instead of nitro (even though we love nitro), and went with the following:

Motor: RC Timer BL-2830/8 1300kV
Prop: APC 8x6e prop
ESC: Hobbyking Redbrick 30A ESC
Rudder Servo: JR PS-51S (circa 1990's)
TX/RX: Futaba Megatech JR (circa 1990's)
Battery: Blue Lipo 3S 2200mAh

All electronics (ESC, RX, and servo) were dipped in corrosionx for water proofing. To help cool the ESC, I removed the covering and replaced the stock heatsink plate with an aluminum finned heatsink from a local electronics parts store (for under $1.00). Plexiglass was used for the radio compartment cover mounted onto foam tape.
