This is a series on building the DR-107 One Design (IMAC) r/c aircraft from the Matt Mrdeza plan. This plan was downloaded from outerzone.co.uk.
In this update, construction of the fuselage is started. A problem with the plan set is discussed. A neat feature of former alignment is shown. A couple of parts are laminated from lite ply and carbon fiber. I discuss consideration for access to the motor battery.

Hey Man, I'm new here. I've been flying Rc Scale aerobatics my whole life. I'm really digging your project. Keep posting. I watch videos like yours when I'm building in my workshop. Cheers

Thanks! I'm glad that you are enjoying the series. What do you build?

@BalsaAeroProjects I don't build anymore, my friend. I mostly just assemble arfs and make my modifications if I need to. Growing up in my father's basement thats all we did was kit and scratch build. But he's gone now, and I don't have the setup where I'm living at the moment to start carving and sanding balsa wood. That's why I enjoy watching videos like yours where you trouble shoot and work through problems. I don't have to sneeze out any wood either lol. I penciled out plans for a DR-109 when I was younger. That's as far as that project went. It's cool to watch yours coming together

@@alwaysflying6540 I know what you mean about smaller places with no room to build. I was in a situation like that for 10 years and couldn't build rc so I built plastic models. Learned a lot about painting in those 10 years. I'll have to look up the DR109. Haven't heard of it. Maybe some day you'll get a chance to build those penciled plans. I'll do my best to keep the videos coming. Thanks for watching!

@BalsaAeroProjects the DR-109 is the same plane as yours but a two place. Longer canopy lol

I think you did not keep account for the fact that the fuslage tapers toward the back. The airplane is drawn as viewed from the side when assembled. The aft portion of the fuselage sides are therefor pivoted away from the viewer. When they are projected into a flat view the become longer. Maybe not as long as they are now but certainly longer than on the main plan. I have workd with CAD my whole life and have drawn quite a bit of RC plans hobbywise as I had them means (and the hobby) :-)

Yes, that thought did occur to me regarding the fuselage sides and doublers but that still doesn't account for the formers that are too big. Also, In update 9, I talk about the horizontal stab being too big as well which also comes from the template page and it's just a flat plate. So, while I agree with your thinking on the fuselage curvature, I think the whole template page is simply too big. Thanks for the input!
