Tom's RC Motorboat

thingiverse

Tom (a friend of my son) asked me for a boat hull to be equiped with radio command hardware. I started buiding this first trial, to be tested... and continued. It has a helm and a propeller shaft and is waiting to be filled with stuff to be controlled (battery, servos...). It's a relatively large one (more than 27 cm long) and I printed it in diagonal on the bed (I think it's the largest thing I printed on my RepRap Prism. It is a bit bulky (but it floats) and can certainly be improved (you can derive it). You can add a propeller (at the end of the shaft) like the one I found here : http://www.thingiverse.com/thing:15354 (double sized to fit the scale). Instructions 1) Print the hull. More than 5 hour for my RepRap Prism (It's a quite slow one, but beware of vibrations that can compromise your correct printing if you decide to speed up). I printed mine in PLA (but it's not ideal to stay a long time in water, because it can disolve). No support needed (I put frames to reduce printing bridges). Relatively low infill (from 15 to 30% I guess). 2) Print the helm. 3) Fasten the helm to the hull using a small piece of filament introduced in the holes made in both pieces. 4) Test the balance and buoyancy 5) Install hardware to radio-command it (propeller, battery, receiver, servos...). 6) Test the balance and buoyancy (again with all the stuff installed). 7) Enjoy !
