slngsht Posted February 27, 2010 Posted February 27, 2010 Man, I'm sucked into this hobby hard :willy_nilly: Experimented with some foam cutting last night and made my first wing today. I'm using my battery charger, some coil wire off a $2 roll at radio shack, a plank of wood and a screw as the foam cutter. I'll invest some more time in making it more permanent now that I know it does a good job with cutting large cross sections. The surface texture of this wing is nearly perfect. very smooth. I does have a bit of curve to it because I wasn't holding it down enough. Here are a few pics, and my assistant. http://www.astarasoftware.com/images/rcstuff/wing1.jpg http://www.astarasoftware.com/images/rcstuff/wing2.jpg http://www.astarasoftware.com/images/rcstuff/wing3.jpg
slomove Posted February 28, 2010 Posted February 28, 2010 And I thought you had made a wing for Franken7... But that one is looking good, so who needs a CNC machine?
Arya Ebrahimi Posted February 28, 2010 Posted February 28, 2010 He doesn't know it yet, but Mazda is just doing all this RC stuff so he can learn how to carve shapes in foam to better the 7
slngsht Posted February 28, 2010 Author Posted February 28, 2010 Every hobby builds upon past experience. My next 7 will have a rudder on its wing. LOL
DeanG Posted February 28, 2010 Posted February 28, 2010 There is a trick to cutting wings. Mark and number points on each template. Have 2 people move the wing/cutter very slowly with one person calling out the numbers so you both stay in sync. You are trying to keep the wire straight and keep it moving.
slngsht Posted February 28, 2010 Author Posted February 28, 2010 Yup, i discovered this last night. On the next attempt, I will control both sides of the wire.
ottocycle Posted February 28, 2010 Posted February 28, 2010 Mazda, Looks cool. Do you need to seal the foam before you glass it or is the plane so light you can mylar direct onto the wing, ie. it will not need additional strengthening. Do you rout in a spar or strengthen it some other way? As a kid I built balsa models but never worked with foam. it looks like a good way to build mouldless bodies. Have fun, Dermot. PS. I love the Potomac workbench!! :0
