    My Homebuilt RC Micro Paper Se5a

    There is steady, but slow progress on the 3rd build. A lot of things are competing for my time and my studio is hot as Hades after 11:00 am. It's hard to do paper modeling when you drip all over the parts. The airfoils are complete, and to a very high standard if I do say so myself. I built...

    My Homebuilt RC Micro Paper Se5a

    Good trip, and we never had to motor very far. I was the junior partner, but performed credibly. Day one was excellent small mouth fishing. Between the two of us we kept a 14, 15 and two 17 inch. A few pan fish were taken as well. A late morning 18" small mouth was released and we were at...

    I'm a bit behind schedule, but then again I need to earn the money to pay for this hobby! All the Se5a airfoils have been revised and assembled for build No. 3. I'm really pleased with the results - I've never produced such true airfoils with such consistency and ease AND they are...

    My Homebuilt RC Micro Paper Se5a

    I had less time to hobby than I would have liked this week end, but made some good progress, largely "virtual" rather than actual building. After assembling the first revised wing I realized some minor changes could save more a bit more weight and result in a wing that is actually a bit easier...

    My Homebuilt RC Micro Paper Se5a

    I save 0.048 g for every square inch I can remove from my patterns. .0075 g cm2. Easy enough to do, might save a fraction of a gram with due diligence. I have been a bit lazy with some of my patterns to save scissor work. I just went to my plans and made 8 cutouts in my wing spar/spacer...

    My Homebuilt RC Micro Paper Se5a

    Ramping up again after the 4th. Hot as hell at home, I like to build early in the morning so I don't sweat on the paper. AC is used sparingly! I've been looking into wire alternatives, and it's going to be hard to beat the 6 strand phone cable wire for price and weight. I may be able to...

    My Homebuilt RC Micro Paper Se5a

    Schorhr suggested roughly the same thing way back when I first started. I could actually run the wire strands along the insides of the fuselage and solder in some short connection leads to mate up with plugs etc. It's an attractive idea and I'm going to pursue it. It would neaten up the...

    My Homebuilt RC Micro Paper Se5a

    Having not much to do early this AM, I put my latest build on the scales to get a weight. :eek: It had gained 4 g compared to the original! Now I had made a few modifications to the fuselage, but 4g is nearly one whole sheet of extra paper. Had I forgotten to weigh the battery in the...

    It's a very cool model. The Wrights got it half right, but they picked the right half (Blade element theory).

    Here is the link: http://s6.aeromech.usyd.edu.au/aero/propeller/blade_element.pdf There are implementations of this available. I wrote my own in mathematica, but when I upgraded to Windows 7 I couldn't download my very old Mathmatica to my new computer. I may have an Excel implementation...

    My Homebuilt RC Micro Paper Se5a

    Thanks Zathros, that is one very informative article. Actually, a whole bunch of 'em. Right up in the introduction I see: "In the good old free flight days, test glides were the norm, trimming out a model into long grass until the model flew straight and level just off the stall." I...

    I've appreciated the discussion about what to do next. It was supposed to be sunny today, but we got rain instead, and the ground is soaked. Weather prediction is unreliable in the Mid West USA. Here is my plan. I going make sure I know where the CG is on the current RC prototype. Then, I...
