    Aileron balance

    Okay, definite waste of time.

    Aileron balance

    Nope, not just that, and not just "perfecctly balanced". As I mentioned above, I have a number of questions about the effects of this linked weight and pivot as a system. And if I personally knew the answers, I wouldn't ask the questions.

    Aileron balance

    Me. too. I call em like I see em, just like the rest of the gang.

    Aileron balance

    There were no "offensive" remarks made. And understand the report function.

    Aileron balance

    In this system in a dive the mass inertia plus weight will oppose an aileron's flutter displacement upwards, and the mass inertia minus the weight will oppose it in the other direction. Thus a dynamically unbalanced force. How will this play out in this design?

    Aileron balance

    In a rigid connection to an aileron of a mass balance weight, they both behave as a single object. In a linked connection between a weight and an aileron, they don't. If there is any play or flexibility in that system, there can be a resonant response created. How will that play out in this...

    Aileron balance

    Okay, thanks for that straightforward answer. The amount of balance mass isn't the only thing I don't understand about how this design will behave yet, but I accept that as true.

    Aileron balance

    ya know, I was askin a straightforward question because I didn't know the answer, but I guess that's impossible without gettin' smartassed remarks. I understood the mass balanced part of balancing ailerons, what I was wondering about is the effect of the weight, anyway, since both the weight...

    If you love aircraft-- "Doc"

    Thanks for that Pops. My stepfather was a B-29 navigator-bombardier out of Saipan.

    Aileron balance

    I've got a question re. an aileron balance design I saw in a build thread here. The balance weight was put on the end of a pushrod near an internal horn. Q: What happens in a dive?

    Decalage angle

    note: "bottom of foil" + stick is probably back now to fly at all.

    Decalage angle

    Ayup. Maybe he should have moved the wing forward instead. Like right over the seats. Might need to move that big engine to the front, too, to balance.

    Decalage angle

    Decalage is a pretty aero word. But, individual wing and tail incidence carry more information than simply the difference between the two. Unless it's being applied to a biplane's wing rigging, it's kind of useless to generalize about it.

    Decalage angle

    I trained on a Drifter. It's a tandem 2 seater. Easy to balance a load. Apples and oranges, again.

    Decalage angle

    Apples and oranges. Convert your Boorabee into a 2 place side by side with both forward of the CG and additional frontal area, allow enough range of CG to accommodate all 2 place load conditions, then see what incidence you have to set on the wing and tail to achieve that. Then check the drag...

    An alternative to flat wrap

    I usually peel mine for models anyway, so glue adhesion is good. The dow blue peels easily. The pink Owens Corning is a pain, plus it's so wavy and uneven, I would think it was useless on a full scale plane. Fanfold Dow is about 5mm thick, while Owens Corning is roughly 8mm. I would guess for...

    An alternative to flat wrap

    Jay, I have a couple of bundles, myself, but purchased back when Loews carried it several years ago. Who is your local supplier? What was the method you used to set up a supply chain? That information would be really helpful for people on RCGroups to know, since the people I know there have...

    An alternative to flat wrap

    A few things: 1.) Hephaestus, ("Blucore, Dow blue etc.") polystyrene foam NOT polyurethane. Important NOT to try to cut polyurethane with a hot wire because of toxic fumes. 2.) pictsidhe, Elmer's foam board is REALLY tough to remove the paper from. I've done it but avoid if possible. I use hot...

    Weight and balance calculator?

    mstull wrote that he used to hang his planes to find the CG, but no need to photograph or cross lines to do that. His were tube UL's so, easier to do those. Proppastie your method would work one time, but would have to be repeated for any change, since the CG height would also change. Easier to...
