The projects start of simply enough. I set out to create a simple boat that was easy to print. Somewhere in the iteration phase - apparently about 80 so far I come to the realization that perhaps some assembly instructions would be in order as the parts list has grown somewhat.
This blog is where I'll post construction info of the Fandango fan boat. As a starting point, you can download a printable pdf exploded diagram of the image above
Needed Parts list:
This boat uses twin counter rotating racing drone motors for propulsion. Why two? Because in the development process we discovered that these little motors have so much torque they will capsize the model. Counter rotating motors cancel each other out with the added benefit of double the thrust. We used Diatone 1405 motors on ours.
You will need two bushless speed controllers. Verify your max amp allowable for your motors. The Diatone motors we used had a 10 amp max limit. If you over amp your motors you will burn up electronics.
you will need 1 micro servo for the rudder.
Battery: 3s 2500 MAH lipo. This is our choice:
Radio Transmitter and receiver.
I highly recommend using a water proofing agent on your electronics. My choice is this Conformal Coating.
I really like the use of threaded heatset inserts for a more durable model. On this build 2.5 mm ones should work just fine.
Print Bed Orientation:
Hull Stern: See the image below. this boat has a raked rear stern. In order to print without using supports ensure that you orient the print so that the transom side is down. You can then use the "Lay flat" on the rotation fly out illustrated below to ensure it is flat to the build plate.
