RE: Learjet 31A Build - Mark Frankel Design
Actually never flown a Falcon in my life though I rode in a 2000 once. Falcons was the team name for my college flying group, we had a bumper sticker that said Fly Falcons, and it just stuck with me. The 31A is the best performing jet I've flown, but the least comfortable. Fortunately it also has the shortest range. Your model looks like it captures the look of the 31 perfectly.

RE: Disappointed in RC Advancement Over Last 20 Years
[quote]ORIGINAL: on_your_six I hate the ''Remember When'' nostalgic thread currently running. Sure it is nice to remember how it was, but I have to question why the snail slow progress in the RC technology? I bought my first 7 channel RC radio about 25 years ago... and there has not been that much progress or advancement since proportional radios were introduced. In the same time span, I have gone through about 10 computers with remarkable advancement each time. Radios with programmable functions have not been around very long. Telemetry is still in its infancy and few people are enjoying its benefits. Microsoft flight simulator arrived in in 1995. The RC simulators have not caught up yet with realism. I expected a lot more from RC when I got back into the hobby. WHY SUCH SLOW PROGRESS IN RC? I say remember now, it's not that great now. [/quote] Have you heard of this movement lately called Occupy Wall Street? It's a bunch of whiners not knowing what they are whining about, but who love to poo their pants and skip showers for, say, two months or so. They do so for the attention they receive, mostly disdain and embarassment for what people do (and whine about) these days. Why do I bring this up? I'm not sure exactly. I read this post and immediately started thinking of those losers taking craps in public.

RE: what 2.4 article
Wait a minute, people crashed at Joe Nall and blamed their radios? No friggin way........ A quick scan through the threads where people have radio issues quickly shows the vast majority of them did not install their systems properly (in some cases it was embarrasingly obvious they never took the time to read any setup guidelines whatsoever). In practice, not in Greg's mind, 2.4 has proven far more reliable than the 72mhz systems we used to run.

RE: Downwind turn Myth
[quote]ORIGINAL: haikt I have a question In DS soaring the plane adds speed with each loop and can achive speeds up to 200mph. If steady wind does not have an effect on the airspeed (lets say speed of air over the wing) and it is only ground speed (our perspective) then why does the plane fail (wing or fuse damage) what am i missing [/quote] Actually those crazy SOB's are hitting 400 now. Bring your kevlar jacket! Anyway the reason that DS planes are hitting these speeds (and those speeds are measured on the back side, in calm air, so they're really going that fast) is because they are flying through a shear layer over and over. They fly on the back side of the mountain (on the lee), where the lower air is calm and the air above the top of the ridge is moving quickly. Traditional slope soaring is done on the front side of the hill, with (in comparison) a fairly steady wind.

RE: Downwind turn Myth
Tisk, tisk, Larry. Think of this as a wind triangle. To offset the 20 knot headwind, the aircraft must be making 20 knots of forward progress through the air (the X axis). By flying a vertical line with reference to the ground, you must angle the plane up (now think of your new flight path as the hypotenuse of the triangle). Would you mind explaining how exactly the hypotenuse of the triangle is exactly the same measurement as the x-axis when there is any angle involved? Bonus points for using cosine calculation in your explanation. Good luck, we're waiting for you.

RE: Downwind turn Myth
I'm sorry but it's simply not. If the aircraft has an airspeed of 20 knots, any deviation from perfectly straight and level will result in a groundspeed of less than 20 knots in calm air conditions, correct? I would hope you agree. Now, if that same aircraft travelling 20 knots is flying into a 20 knot direct headwind, you would agree that the groundspeed would be exactly zero. Good so far? Great. So, when that aircraft, flying into a 20 knot headwind with a 20 knot airspeed, deviates in any fashion from straight and level (including pitching up), there is no possible way for that aircraft to overcome the 20 knot headwind and maintain zero groundspeed. Sorry but in this case, most junior high kids are smarter than you. Draw it out with crayons if it makes you feel better. Have a nice day.

RE: Downwind turn Myth
It's really simple, Larry. If you are flying at 20 knots airspeed in a 20 knot wind, it is not possible to fly a vertical flight path. Period. It's simple Geometry, buddy. If you were smart enough to get to (and pass) junior high geometry, you would understand the vectors do not allow for anything but level flight at 0 knots ground speed. Pull up even slightly and at 20 knots airspeed, the airplane is no longer capable of 0 knots groundspeed. Chew on that a bit, would ya?

RE: Downwind turn Myth
Sorry Larry, your description is messed up. It simply isn't physically possible to do what you describe. The plane is either flying in a vertical pitch attitude (and with the wind), or it is crabbing (via pitch) into the wind to accomplish a vertical line from a ground reference. You can't just mix them up and expect people to take you seriously.

Where guys who enjoy flying [b]model[/b] aircraft gather? Or am I mistaken and this is a website for full size pilots to look down on the RC peasantry by way of their superior knowledge of AVIATION. You people seem to think that aircraft are flown by ROBOTS. Are we not talking about pilots making mistakes with downwind turns, as in landing and sometimes screwing the pooch because they mistake ground speed for airspeed? And it's even worse for the RC flyer. I dare not say PILOT, do I, that's reserved for the anointed few who have tons of money or are lucky enough to have earned a living by doing what all of us love, and that's airplanes and flying. ............etc etc etc........... YES, if you've flown full size, you have a better understanding of these things and have learned the Aviation jargon to look so-o-o-o-o smart and superior. Good for you. Let me make a suggestion. There are grunts in Iraq and Afghanistan that sure could use your superior piloting skills to cover for them. Go and do that and leave us amateurs to play with our toy airplanes.

Those of us who are educated in this matter understandably get a little frustrated at those who choose not to listen, or think that installing some JR servos in an RC plane makes them knowledgeable in aerodynamics.

[quote]ORIGINAL: wrob [quote]''Once an a/c has broken ground, steady state winds have no effect on airspeed (hence, lift) whatsoever, and airspeed does not change simply because one is flying upwind, downwind, crosswind, or even when alternating between any combinations of the above.

A plane flying up wind has less kinetic energy than does one flying down wind. In general, a plane flying up wind will lose altitude when turning down wind as a result.

RE: Downwind turn Myth
[quote]ORIGINAL: Taurus Flyer I think there are several reason not to talk about an airfoil (cross sectional shape, wing (cross sectional shape and span) but total airplane. Even if you fly your plane under stall angle of the wing (which part is a problem for the designer!) it is possible to stall your plane, and that is problem in a downwind turn with strong wind so high G load to make the first 90 degrees ''location orientated turn''. First is slip in the turn, which AOA do we talk about left or right wing? Ask the glider pilot to prevent slip) Do you modeler have a slip indicator, ISA (indicated slip ange)? Second point is aileron deflection does let stall your outside turn wing even if the total wing is under stall AOA. Important detail for the whole story, I also do fly own designed Horten gliders, there is no [b]ONE[/b] AOA of the several [b]airfoils[/b] on diferent locations of the wing spanwise were we can talk about, same story when washout is used! I design also canards, other story!! Cees [/quote] Cees, you are so wrong it's unbelieveable. For the second time, please list your aeronautical experience, training, and degrees or certificates.
