First Design Hydroplane

Goal: design an RC Hydroplane which can run for 5 minutes on an oval course.

Prerequisites: only a 280gr LithiumPolymer 2s (7,4V) powersource may be used.

Materials used: styrodur (kind of foam), carbonfibre and glassfibre.

 

In following clip the process of building and designing the hydroplane are shown. Also the first testrun is shown:

One of the considerations designing the hydroplane was that it does not matter what dimensions the hull has, unless it is lightweight and not extreme bulky. The only parts that touch water are:
1. propellor
2. (small part of the) floaters/ sponsons

 

To keep the design as lightweight as possible, it was necessary to design the tub as small as possible. Only 6cm width would suffice for the LithiumPolymer powersource to fit in.
