RE: Sig Rascal 110
Has anyone got, or know of a source for, a three-view of the rascal in electronic format? I know it doesn't have as much power as the gassers, my rascal is going to fly with the ASP-160 twin. I love the twins - the sound, the lack of vibration... Should be great for lazy acro.

RE: 1/3 scale balsa usa Flybaby?
I have a BUSA Fly Baby (http://bentrapnell.com/-/bentrapnell/gallery.asp?LID=&cat=17093&pID=7&row=5&photoID=8320238&searchTerm=). Built more than twenty years ago. It's got an old quadra 35 for power. Takeoffs are very scale, flies like it is on rails but with all the drag, and so little power, fast is not in its vocabulary). Will loop if you lower the nose to gain some speed. Rolls are helped a lot with rudder in the direction of the desired roll (yaw-roll coupling...). Nearly lands itself (don't ask me how I know...). If the aircraft was built properly, you should really enjoy the aircraft. I know I do.

RE: ThunderTiger Rare Bear
Richard - I can't say a word about the YS-110 as I haven't flown it. The Saito 1.80 I have will turn a 17-8 APC at 10,600 on coolpower 30% Heli Fuel. Saito's just love that heli fuel.

[quote]ORIGINAL: A. Holden As I said above- I can't say enough good things about this ARF- there were a few issues that I ran into but nothing that I couldn't over come- That is typical with any plane I think- Dion and Mike have been there to answer any questions that I have had and were a big help to me- THANKS GUYS!!!!! YOU ROCK!- OMP definetly makes a quality product and they also stand behind it 110%- I would tell anyone looking for a GS profile that this is a great plane and super easy to build- More pics and video coming soon Alex Holden Pro Bro #555 alex2@aholdendesigns.com [/quote] What, exactly, were the "few issues" that you ran into and what did you do about them? I know this was not intended to be a building review, but you got my interest up with the pics and comments. I've yet to start mine but would like to be armed ahead of time about potential "issues" and have all my "ducks in a row" so to speak. Thanks

Southern Kite
Has anyone got any information on this glider? I'm looking for a kit, preferably with a glass fuselage, though I would take a wooden one if I could find one. I flew one in Pensacola, FL around 1978-79. Was a real floater, if I remember right. Moose, are you still out there? [:D]

RE: Avoiding spiral dives with rudder-only airplane
That being the case, I still stand by my point of ensuring the directional static stability is weaker than the lateral static stability. How one intends to do that is academic.

RE: Avoiding spiral dives with rudder-only airplane
I agree with LouW. Look back to the Nordic fliers - their gliders had [b]very small [/b] vertical stabs and lots of polyhedral in order to maximize lateral and reduce directional static stabilities. Stronger directional than latteral will most likely lead to spiral divergence while stronger lateral than directional usually results in dutch roll. The nordic fliers had/have movable rudders that would remain faired while on tow and deflect a little when the tow line was released to induce a turn that would be conducive to thermaling. Small rudders [b]and[/b] small stabs. If the yaw rates get too high, which [b]will[/b] happen if directional stability is too great, even the large polyhedral won't be enough to prevent spiral divergence. My 2 cents... Trap

RE: Sig Cap 231 EX ARF
I fly mine with a Saito 180 and APC 17-8 prop. With 30% heli fuel the engine sings and one might be able to hand launch the plane... I've never had a plane that would do better knife-edge spins than this one. With power, it tends to go a little flat and the sink rate slows right down. Don't think there is enough power to climb in the spin, however. Floats on landings...Just don't let her "plop" at the end of a flair. The fuse is a little tender, but most light aircraft are. I think for 3-D, however, the Edge 540 (hangar 9(?)) is a better plane. Rolls off a lttle less during harriers. I like my Sig. Good looking airplane with all the stickers applied....

RE: Coaxial contrarotating propellers
I may be sticking my you-know-what out a little with this but, I believe the term to be used is contra-rotating. Counter-rotation applies to planes like lightnings and Piper Seminoles - planes where the propellers of the opposing engines turn in opposite directions. To put it simply, the second propeller straightens the airstream in an attempt to recover the energy in the swirling stream of air behind a normal propeller. Airplanes with incredible amounts of excess horsepower (Bear Bomber, etc) use them so prop diameter doesn't get too large (tip speeds too high). The Pogo and the Salmon used such props to counter the torque effects of swinging a large prop at near-zero airspeeds.

RE: Golden Rod?
Mike - go to the local sporting good store and buy an easton carbon arrow shaft. Go the the local hobby shop and buy a section of 4-40 rod long enough to make a two inch section for the servo-end and one long enough to go through the transom of the boat and extend about an inch in the arrow shaft. Use a dowel of the proper diamerter to make a plug in the ends of the arrow shaft. Drill a hole in the plug so you can epoxy the 4-40 shaft in the end about an inch. Epoxy the plug into the arrow shaft. It will be plenty strong for your application. If you need even more strength, make a few bulkheads with holes that allow the arrow shaft to slide through with little friction and mount them from beam to beam with epoxy and a little glass to reenforce the joint. It's not that hard and should allow access to the rest of the hull. I wish I could draw this out. It's much easier done than said. Ben

Fly-Baby Bipe
Anyone else out there flying a Fly-Baby Bipe? I'd like to hear from you. Mine is also from Balsa USA. It was built 21 years ago by a man in Minneapolis named Don Martin. He even used his own hair for the pilots eye brows! The engine is a quadra 35, also 21 years old! It hadn't flown until last year. ON the 35, it flies extremely scale. Very slow, but a floater, not so much a brick. Wish they still made the kit. The plane has lots of character and never fails to turn a head at the events I go to.

Airliner finlets???
Vortex generators (vg's) turbulate (add energy) while fences reduce spanwise flow by redirecting (or excluding the low-pressure area on the outboard/downwing side). Another type of device seen is the vortelon. Invisible at high speeds, it adds energy to the flow at low-speeds by taking advantage of the spanwise flow.

vortex generators
VG's are used on some multi-engined light twins to lower Vmca while those on some large transport aircraft may be used to delay separation, decrease drag at high transonic speeds. They tend to reduce the magnitude of the shock wave produced at Mforce divergence. Interesting how they work at low and high speeds!

Speed of sound vs. elevation
And as we teach commercial pilots, M=TAS/a a=local speed of sound (speed of sound at altitude you're flying) which varies only with temp TAS=true airspeed (actual speed of movement through the air) Now, who's going to be the first to build a model that can break the sound barrier?
