[RCSE] RE: EPP Racers

2000-01-05 Thread Nathan & Marni Woods

"What "makes" a good slope racer/aerobat?"
--
Great question Darwin.

Here at Temple Hill, we have seen a fair number of fast foamies, featuring
the home hill of several of the top EPP manufacturers, plus the noble and
successful efforts of a scratch built model by Mike Robinson.

What I have observed are the following desirable traits:
- Straight line speed
- Energy retention
- Stability in bumpy/gusty lift
- Tight turns
- Ballast bays (variable wing loading)
- Durable, not necessarily indestructible, but easily field repairable
- Easy to build by a doofus like me (meaning, incidence, CG, etc... is
predetermined)
- Stiff wings (DS'ing is inevitable with a fast foamie)

I'd recommend a detachable wing design, with multiple but very flimsy nylon
screws.

Also, the ability to pump up the aileron throws during sport (fun fly) mode
for killer aerobatics.  Inverted flight is a plus, but not at the sacrifice
of straight line speed that a symmetrical airfoil necessitates.

If you need more beta testers, I'd be more than happy to help you out :-)

[RCSE] On topic - soaring

2000-01-05 Thread darylp

Well folks, the parts are here. My new TD model has arrived. Well,
actually, I've been working on the fuse for a few days now. (It's almost
done) It's VERY stiff, and light. Carbon, and Kevlar reinforced s-glass
fuse. Came in at 7.1 ounces before I started playing with it. Looks like
the fuse, no joiner, but with stabs will be flying just under 20 ounces.
19.5 to be exact. The wings are 15 a side. With servos, we'll be looking
at 17 a side, so realistic total at 34.5. These things are very nice
bagged wing spotlanders. Kevlar hinges and all! I'm still waiting for
1/2 inch joiner - (Paul? D'ya get my e-mail?) Anyone know what those
things weigh? 

I'm guessing all up weight at 58 EASY.  

Span? Well I guess I could tell ya that - 120
Planform? Yes
Sections? I wouldn't even tell my mother what sections I put on this one

Name - "Neurotic" - s - it's just a little psyko

Don't call Sal about it. He won't sell ya one. I made him promise. 


Daryl - Can't wait for contest season - Perkins

PS - I won't be flying it at SWSA this weekend, so don't come out ;-)

[RCSE] RE: EPP Slope Racers

2000-01-05 Thread Darwin A. Garrison

Hi, Guys:

I have been watching this thread with considerable interest.  I have
managed to take a look at a couple of web sites showing pictures of the
currently available "slope/aerobatic" models, and I find the entire
realm fascinating.

I am currently in the process of building an initial prototype of my own
concept, which is being made to a request from an individual in
California.  I have taken a completely different route than the other
models that have so far been available for review on the web.  Since I
don't slope, my flat land tests will involve bungee launches and high
speed diving.  After that, the prototype will journey to CA for some
real tests.

I am curious, however.  What "makes" a good slope racer/aerobat?  Is it
raw speed? Fast handling?  Energy retention?  How about the criteria for
an EPP racer?  Is "more durable" acceptable over "indestructible"?

I've already made my design choices for the first iteration (something
of a compromise on the above criteria), but I would welcome some insight
to carry with me during the test flight stages.

Regards,

Darwin Garrison

I also saw Bills Brisk fly off of a winch launch.  The plane seems like it
is not bad in the thermal dept. either.  There wasnt much lift but the Brisk
seemed to hang in there quite well.  Pretty impressive considering that not
only is the Brisk primarily a sloper but also Bill was flying a new plane
w/little or no stick time on it.  The Brisk certainly looks like a winner to
me also.  Boy, there are so many good planes out there to choose from now-

Hello, Ron, thread watchers:

I regret that the Hand Cat has yet to reach production.  This is an
unfortunate result of having too many pies to eat.

HOWEVER:

I did more or less finish my redesign over the Christmas holidays,
including cutting a proof of concept fuselage pod.  We learned many
things going through the trials with the initial prototype, especially
when it comes to making sure the plane is durable while still keeping it
light.

The P2 Hand Cat features a revised wing planform, different, modified
airfoils, a V-tail, and  revised internal layouts.  All of which came
from our experience with the first prototype.  The new model has a
target weight of 10 ounces, and should launch higher, turn well, and
range further during its flight.  It also has a much more comfortable
and effective launch grip.

If there's enough interest, I'll post some .gif shots of the CAD file,
and maybe a digital pic of the new pod.  As soon as I complete and fly
the P2 prototype, I will post a writeup and pictures to the web page.

Target date for production kits is sometime during March.

Regards,

Darwin

Hit the delete key if your not interested, sorry, but I find this

I am amazed at the number of RC soaring guys who are/have been sailors.
(I rec'd a lot of private responses also)

I saw the same program as Brett. The landsailer in question was VERY
impressive. It was designed and built for one thing - to get the land
speed record for land yachts. It was all composite, with long flowing
lines. Even the cockpit was enclosed. It was very clean. The sail/wing
was VERY high aspect ratio, all composite/molded. They were driving this
thing on what looked like a runway, (it wasn't the salt flats) but this
was not the record attempt. They said they had already gone faster than
the current record of (I believe) 88 or 89 mph, and I seem to recall
them saying they had been over 100 mph. The driver was impressed with
its ability to go very fast in light winds. It was impressive to watch
the "boat" accelerate. I now wish I was paying more attention so I could
give you guys more accurate figures.

I'll do a little "surfing" so I can offer some pics.

Re: [RCSE] Sailboat "Wings"

2000-01-05 Thread Cliff Lindgren

OK, here we go.  There is true wind and there is apparent wind.  Apparent wind is the 
wind you feel if there is no wind and you're
on a bike and you start moving forward.  It feels like there is wind, right?  
Sailboats use wind and forward motion to work.  Proper
sail trim is extremely important to achieve maximum efficiency from any given boat.  
You are manipulating your "wing/sail" with many
different lines. OK.  A close hauled (point of sail into the wind)  mono hull sail 
boat can pretty much only go what is called hull
speed.  Now, you crack off the sails a little, head off the wind a bit and you start 
generating more of your own wind by gaining
more speed.  This is the true wind and your forward motion combined, hence more 
apparent wind and hence more speed.  Anytime you
sail past where the apparent wind is on your beam you throw up your spinnaker (big 
pretty sail) and you go even faster.  Your sails
are still working as a wing and you are being "lifted".  That is until you are running 
down wind and then you only go as fast as the
true wind is blowing.  You cease getting lifted by your sails anymore.   Your are 
"running before the wind".   It doesn't matter
what kind of a boat you are on either unless you are in a situation where you have a 
planing hull or there are waves and you
break-loose and start surfing.  ULDB's (ultralight displacement boats) which became 
extremely popular in the 70's can surf the ocean
& bay waves very well.  Once down wind its only as fast as the wind is blowing for 
most boats.  Its a pretty scary point of sail in
a blow too.  In sailboat racing, un-wanted jibes while running down wind result in 
what is commonly know as the "death roll" and you
can be pinned on your side if you "round down".
OK, in the medium of the ocean there is a lot of drag from the water.  On land with 
only three wheels on the ground there's a lot
less friction.  On ice its even less.  That is why extreme speeds can be achieved in a 
realitivly light wind.  Its can pretty much
be summed up by saying " the faster you go, the faster you go ".
OK, so now if you want to sell all of your gliders and buy a sailboat and want to live 
on the wild side, buy a mutli-hulled sailboat
and go real fast.  Be prepared  to get wet though.
I am sure there is a much more scientific explanation and I'm looking forward to the 
many theories forthcoming on this glider
exchange.

Re: [RCSE] Re: EPP HLGs

2000-01-05 Thread RH1037

Looking at the Javelin, though it seems a bit heavy at 15oz..and the Hand 
Cat from Garrison Aerodrome, though not sure it is in production yet.. 
Anybody have any ideas on how to lower the weight of the javelin, and know of 
any other choices I may consider in EPP HLGs?

Re: [RCSE] DONT buy topo maps on CD until you've been to this site!

2000-01-05 Thread Bobbi and Randy

WOW! I just typed in "The Lump" where I fly which is a rather obscure
landmark that I thought would never be found. Not only was it found but I
got an incredibly good map of the area.

Thanks Scobie.

[RCSE] Servo Clutch

Such a device is used on the steering linkage every RC car that I have
ever seen.  It protects the steering servo when the car bangs into the
curb, or whatever.

I recently gave one of these clutches to my friend to try on his Wild
Skies Fox on the rudder.  The rudder is so heavy that a slightly rough
landing will either strip the servo or break it from the mount.  I'm
sure that the car steering clutch would work if used.

For a plane, one way to protect the servos is to mass balance all of the
control surfaces.  This will ensure that dynamic loads on the control
surfaces from hard landings is minimized.  It still does nothing for the
loads on the servo when the control surface hits the ground, or hits a
rock, or whatever.

Re: [RCSE] Music Wire For Wing Rod?

2000-01-05 Thread mark wolfe

Goto an industrial supply house and get 1/4 drill rod, it's straight,
unless you need a bent rod, in that case, I've got some here from
crashes. :) 
The music wire you get in a hobby shop isn't straight, and if you look
at it, about ever 6" it's got a little mark where they unrolled it off
the roll.
