Installing components
All electronic and stabilization components were installed.​
​
-
Propeller, flex shaft, rudder, strut, and steering stabilizers were installed
-
Motor controller (HobbyKing 50A boat esc), receiver (Turnigy 3xs), and steering servo (mg996r) installed.

Water cooling system installed (from the rudder, through the motor controller, through the motor, then exit on the side port)
Test runs
The first plastic propeller made the boat hard to get up to plane and broke after the fourth run.
​
​
​
The propeller was replaced by a beryllium/brass propeller with a higher pitch that decreased plane times and improved efficiency.
​
​
​
The average cruising speed was 20 km/h and the top speed reached was 50 km/h.
The stability of the v-hull was outstanding even at top speed.
