FAN FRIDAY FEATURED BUILD BY Kelly McElderry
Circumstantial inspiration strikes, it can be a multitude of things that inspire us into build action. In this particular instance for Kelly it was to stave off Winter Blues and being held hostage by mother nature that drove her to the build table. One of the absolutely favorite things about this build to us, is that they used easily attainable items as well as a few electronics they had on hand. Foam board….. people, foam board…… What an amazing way to showcase, you don’t have to spend a lot to get a lot. So many things to love about this; building from scratch, google pics for design, materials used, creativity at its finest.
BUILD COMMENTS BY KELLY:
There is an ice storm in the near future and the wintery blues are keeping us indoors, so what else to do than to sit down and become mad scientist! The project started with a stack of Dollar Tree foam board, an overload of hot glue sticks, and a pile of RC motors and electronics. We intended to make a generic fan boat but as we started drawing out the design, the flat bottom and square deck didn’t seem to peak our interests!
We started construction of the hull with foam board. We got our base design ideas from google images. From there we used templates and test fitting to achieve the look we were going for. After finishing the hull, we built the canopy out of more Dollar Tree foam board and kept the idea of a tactical look in mind. We cut windows out of 2 liter bottles and used hot glue on low heat as to not warp the plastic. To secure the canopy we used rare-earth magnets so it can easily be taken off and on. We began construction on the trusses using 1/8th inch thick aircraft grade plywood. In order to keep the structure light and strong, we cut out the center of the trusses. We built two 90 degree trusses straight up, also cutting out the sides. On top of those trusses we built out a rear rudder mount plate, making sure to cut out lightening holes on that piece also. From the top of the rudder mount we ran 1/16th inch piano wire down to a base plate made from 1/4 inch plywood secure to the back of the fan boat with gussets. Using 1/8 inch plywood, we cut out the rudder fins. The rudder was then secured to the wire using wheel collars and 30 minute epoxy. We decided to use an E-Flite brushless out-runner motor 840kv swinging a 11 x 8 inch prop. The motor was mounted to the 90 degree upright trusses using 1/4 inch aircraft grad plywood for the fire wall. To power the brushless motor we used an E-Flite 35amp helicopter ESC that we double side taped the bottom of the motor mount for better air circulation and cooling. For control of the rudder we used a JR ST47BB standard ball bearing servo that we hot glued into the top desk. To control all of this we used a Spectrum AR6200 Ultralite receiver that we taped to the top of the mount behind the fire wall.
To add final touching we dressed up all the wires in orange snake skin to match our RC HUB stickers. We also built into the cockpit to make a captain’s chair and dash for my red-headed action figure to easily fit into when she isn’t tearing up the rock crawler! After that was all done, we started the paint process. We began with a light coat of polyurethane minwax to seal and treat the foam for paint. Once that was dry, we spray painted with satin black to finish it up and applied our RC HUB stickers to set it all off! Next time you’re stuck inside, break out your foam board and see what crazy mess you can get into!
