Product GoalsDesign an amphibious RC plane

Water, air, land manuvering

Develop Target Audience Who will want to purchase product?

Product must be cost effective Reasonable Price?

Step 2: Market Research Research was conducted on similar

RC products that had similar specifications.

Design A (Landing Gear)•Landing gear inside fueslage•Won’t interfere when landing in water•May be subject to water damage

Design B (Landing Gear)•Landing gear assembly stored in wing•Laid out horizontally (perpendicular to fuselage)•Lowered 90 degrees to operational position

Design C (Plane)•Propeller on nose of plane•Battery and Motor stored in Fuselage

Design D (Plane)•Propeller towards rear of plane•Motor and battery stored in rear as well•Would not interfere with plane function while in water
