Re: [RCSE] Hi Tech 5125MG Digital Wing Servo

2005-12-27 Thread Jo Grini
I bought 8 several years ago for two planes. Ended up with one plane after 
refitting all 4 in the wing.

Almost burned w hole in the wing
http://www.jojoen.no/hitec5125.jpg

Probably just fine for TD normal launching when you dont want to break that 
braided line. But for any hard launch or hard landings they are not up to it 
on a 3+meter model. If they were to change those gears to some machined ones 
I would buy the servo again.

I bought a Pike from Tom Watson (maybe the one he refers to). To make 
a
long story short; I stripped both HS 5125MG aileron servos on the first 
hard

launch. It wasn't really the servos fault, aileron flutter was the real
problem. I switched out those servos and put in a couple JR DS368 servos.
The ailerons still fluttered. The DS368s were not harmed but rather were
ripped loose from their mounts as the wing tips were ravaged by severe
flutter. That is a very short version of a long story that in the end 
taught

me two very valuable lessons:

1) JR DS368 servos are very much more robust than HS5125 servos. The 5125s
may be OK for ordinary use but if you want servos that will survive a lot 
of

abuse then the DS368s are better.

2) The Pike Superior in the SL (super light) version was not intended for
hard launches with extremely fast zooms. It was made for early 
morning/late
evening flights in low wind/light lift conditions where light weight is 
very

important. It was anticipated by the designers that in low wind with hand
towing you would not be able to do really hard launches with extremely 
fast

zooms.

I don't own a Pike anymore. I use all DS368s on my Supras since I tend to 
be

an abusive sort of guy.

Frank,

Sounds like you are taking on a project that may be 
a bit beyond your experience. No problem, just make sure you are getting 
good advice -- make sure that person has been there and done that. 


When you move from the usual stuff, like TD or 
smaller sailplanes to larger scale ships, especially 1/3 scale, the forces 
involved and therefore thebuilding techniques are different.

I have built several larger scale ships. I've 
made a lot of mistakes for you. I have articles here.

www.kcse.us, look 
under articles section

To answer your question, no, regular US Obechi is 
not sufficient BY ITSELF as a skin for 1/3 wings IF the skin is your sole 
support for the wing. If you build a foam core wing with a spar system, 
then YES, US thickness obechi will work IF you also use some glass or carbon 
fiber beneath it as part of your composite construction.

I have used, and recommend Avia sport pultruded 
carbon strips for the spar. It is part of a box spar that has been 
discussed and detailed by Dr. Drela. You can scale it up easily to your 
model's size using the Excel spreadsheet also availble at the site 
above.

Good luck,

any more questions, do not hesitate to contact 
me.

Lee

Drela Supra
http://www.rcgroups.com/forums/showthread.php?t=320761highlight=supra


Here is my unofficial take on what is a Supra, gleaned from my hours 
of research:


There were a handful of people building there own Supra before Kennedy got 
his into production, and there are many ways to skin a Drela sailplane 
to mix metaphors...


The Supras that were at the NATS this year (Kiesling, Lachowski and 
Barnes) were most-likely modified slightly from the Drela design for any 
number of reasons.  Mark likes tiny fuselages and some of his construction 
techniques are a bit too time consuming for mere mortals.
The basic parameters of the plane stay the same, the construction 
techniques often differ due to time/material/builder peculariaties.


AFAIK, the wing airfoils stay the same - AG40-AG41-AG42, and most of the 
Supras out there are bagged wings.  Mark's original Supra was 48oz and 
Kiesling said he has three:  two 58oz models and one 64oz model, all of 
them bagged wings.


As far as wingspans and such go, there might be some confusing the Aegea 
130 wing with the Supra wing.  The Supra wing is the evolution of the 
Aegea 130 wing (which Phil makes for the Mantis).  Mark explains the 
differences between those two wings on this page:

http://charlesriverrc.org/articles/supra/supra.htm

I've never heard any discussion on changing length of the tailboom, but 
the fuselages are often resized as Mark's fuses are tidy affairs with 
little wiggle room.  Also, I don't think I've ever seen or heard of a 
Supra that doesn't use that sweet little V-mount horizontal stab.


I have read quite a bit about spar and wing construction alternatives, 
though that could easily take days to sift through.


And finally...

There are a few folks producing individual pieces and parts for the 
Supra...  Les Horvath of CompuFoamCore.com had a fuse/wing/tail core set 
for sale and Bud Elder makes those v-mounts (in varying sizes!).  From 
time to time you'll see folks offering up Supra fuselages, but they come 
and go.  The bottom line is that if you really want to *know* about the 
Supra, go and read through the links I've posted, specifically the Yahoo 
group.


End of last fall, I put together an Aegea Mantis w/ a Luckenbach fuselage 
and Phil's Aegea 130 wing.  It's like a poor-boy Supra.  A lot of the 
same ideas, but different, and cheaper (and heavier).  One day I might get 
my homebrew Supra together.



James V. Bacus wrote:
I have read about the Kennedy molded Supra on the web page, but isn't 
that a Drela Design as well?
It seems when people talk about a Supra (glider) it could mean a lot of 
different things.  Different fuses and lengths, different airfoils, 
different wingspans, different wing construction (bagged or molded), 
etc...

[RCSE] What are you doing to kill 5125/168 servos?

2005-12-27 Thread Tom Watson
Damn...what are you guys doing to kill the flat wing servos?  I used the 
Hitec 5125s on the ailerons of my first Pike Superior (mainly because I 
was lazy and the JR 168 leads were too short) and never had a problem 
for two years.  They get killed the first time out with the plane's new 
owner.  Other flyers gripe about constant gear stripping.


I have the JR 168s on all four wing surfaces of my current Superior and 
it has had no problems, even flying at near full ballast in some pretty 
stiff winds (pulling hard enough to bust new braided line and some less 
than perfect landings thrown in).  Granted, not F3J tows, but still...


The JR 168s are on the ailerons of my current F3B ships and so far, so 
good.  The 168s even survived the...um...demise of my first Furio (may 
it RIP) and that was a pretty violent pile-in.  Enough to break the wing 
joiner in two and split both wings apart - tore an aileron loose and 
ripped one of the servos out of the wing.  Both 168 servos were 
completely unscathed.


Does not compute.  Over.

Thanks George, yes I have thought about 
that.
I am pondering though what thickness the cores are 
designed for. I have never cut cores but I know that the thickness of the 
intended sheeting is considered (deducted) so that after sheeting the desired 
airfoil shape is achieved. Or does a millimeter more or less not matter that 
much? It's an older airfoil anyway, FX60-126 if I remember 
correctly.

  I got a good deal ona 1/3 
  scale ASW-20 kit made by Mark Smith/Dream Catcher Hobby. Unfortunately there 
  are no plans included and I need to know what thickness obechi the wing cores 
  are cut for. I did some research but no success. The common thickness for

  thin for a 5 meter wing. There is a wing made by Mueller in

  sheeted with 1.2 mm which is roughly twice as 
  thick.

I still have the fuse from many years ago and I have set up a standard stick
wing. Hope to fly it at WC '06 or '07. I found a good set of info on the ASW
20CLX - extended wing with winglets.  I am using Dr Drela's BD wing platform
for the wings, 3/16,5/32, and 1/8 hard balsa ribs (Lofted with Compufoil)
with 3/16 ply ribs at selected locations, full spar width vertical webbing, and
layered carbon spars. Cap rib side of LE with carbon and bottom of the TE.
Aileron sub spars generously capped with carbon. Carbon wing rod and tubes. By
the time you have the correct sized obechii, a proper spar built, and proper
vacuum bagging set up, etc, the ribs can be cut and the wing laid up RTC. IMHO
Happy building

PS:laying up and vacuum bagging those long wings could be a nightmare!

[RCSE] Changing Gearsets

2005-12-27 Thread Winch
I'm having a brain f-rt while changing plastic gears on an HS81 servo.  The
gear train appears to be jamming (ie not turning).  The metal drive gear
spins freely as does the first (small)plastic one, but when I put the next
(large)one on the motor ceases to turn.  All the gears spin easily on the
shafts when not in contact with the metal drive gear.  I've changed gears
sets many times before without problems.  What am I missing?

And you can get even more info here:
http://groups.yahoo.com/group/Allegro-Lite/ - the messageboard

Drela Supra
http://www.rcgroups.com/forums/showthread.php?t=320761highlight=supra


Here is my unofficial take on what is a Supra, gleaned from my hours 
of research:


There were a handful of people building there own Supra before Kennedy 
got his into production, and there are many ways to skin a Drela 
sailplane to mix metaphors...


The Supras that were at the NATS this year (Kiesling, Lachowski and 
Barnes) were most-likely modified slightly from the Drela design for any 
number of reasons.  Mark likes tiny fuselages and some of his 
construction techniques are a bit too time consuming for mere mortals.
The basic parameters of the plane stay the same, the construction 
techniques often differ due to time/material/builder peculariaties.


AFAIK, the wing airfoils stay the same - AG40-AG41-AG42, and most of 
the Supras out there are bagged wings.  Mark's original Supra was 48oz 
and Kiesling said he has three:  two 58oz models and one 64oz model, all 
of them bagged wings.


As far as wingspans and such go, there might be some confusing the Aegea 
130 wing with the Supra wing.  The Supra wing is the evolution of the 
Aegea 130 wing (which Phil makes for the Mantis).  Mark explains the 
differences between those two wings on this page:

http://charlesriverrc.org/articles/supra/supra.htm

I've never heard any discussion on changing length of the tailboom, but 
the fuselages are often resized as Mark's fuses are tidy affairs with 
little wiggle room.  Also, I don't think I've ever seen or heard of a 
Supra that doesn't use that sweet little V-mount horizontal stab.


I have read quite a bit about spar and wing construction alternatives, 
though that could easily take days to sift through.


And finally...

There are a few folks producing individual pieces and parts for the 
Supra...  Les Horvath of CompuFoamCore.com had a fuse/wing/tail core set 
for sale and Bud Elder makes those v-mounts (in varying sizes!).  From 
time to time you'll see folks offering up Supra fuselages, but they come 
and go.  The bottom line is that if you really want to *know* about the 
Supra, go and read through the links I've posted, specifically the Yahoo 
group.


End of last fall, I put together an Aegea Mantis w/ a Luckenbach 
fuselage and Phil's Aegea 130 wing.  It's like a poor-boy Supra.  A lot 
of the same ideas, but different, and cheaper (and heavier).  One day I 
might get my homebrew Supra together.

[RCSE] Inexpensive Power towing

2005-12-27 Thread Hank Schorz








Scott Marnoch and I have been doing some towing with the
Multiplex Magister and Easy Glider combination. It is a blast. We have two
Magisters powered with AXI 2826/08 with a three bladed 11 x 7 prop and two
3-cell lipo 2200 maH battery packs. It is a real blast.



Scott made tow cables approx 60 long, and with the
large tricycle gear on the Magister it is easy to get the two up off the
ground. With a Castle Creations Speed Controller, you can program the power
down to about 300 Watts which is more than enough and keeps up the flight time.



You can tow the easy glider quite high and it flys real well,
not at all like a foam sailplane. It is lightly loaded (less than 6 oz/ft sq).
We modified the glider by building a simple releasable tow hook on it. The
Magister has a built in tow release so you can release from either end (glider
or tow plane). That came in handy on the second attempt when Scott (flying tow)
and I (fling the glider) both realized at the same instant that we had a
problem and release both ends simultaneously. That left the tow line free
falling and both planes ok.



I know that Scott has some pictures of the flying, and I
have a couple of the mods that Scott came up with to the Easy Glider for the
tow hook if anyone is interested.



The Magister is about $110 and the Easy Glider $90 or so.
The Magister comes with a stock 680 motor. I tried that first, but its a
little power short.

Re: [RCSE] Supra

2005-12-27 Thread Michael Lachowski
Correction.  I DO NOT have a Supra.  My models are a little smaller and 
have a different airfoil for F3b. I just do a light layup for F3j/TD 
around 60 oz.  Doesn't quite have the hang time of the AG4x series, but 
it will go fast.


You can blame me for the fuselage pod on Mark Drela's, Tom Kiesling, and 
Phil Barnes models.   Mark and Tom used fuselages pulled from the first 
mold made from my F3b fuselage plug which is set up for a different 
airfoil and a flat center panel.  Phil used a different fuselage that I 
did with a little longer nose and the top of the pylon done for the AG40 
and a little dihedral in the center.  I've used this longer fuselage on 
my TD layup of my F3b model to cut out a little nose weight since I had 
a molded tail which I haven't managed to build as light as a bagged tail 
yet.  I also used a really light layup of the F3b fuse with a canopy 
setup for my Bubble Dancer.


Some day I may have a Supra if a mold ever appears with the longer 
center panel of the design vs the shorter center on Kennedy Supra. And 
it would probably have the smaller pod on it.  Phil's Supra130 also ends 
up changed a little.  Production changes designs to suit constraits of 
the materials or shipping.


Phil does have the longest tail boom of any Supra.

Drela Supra
http://www.rcgroups.com/forums/showthread.php?t=320761highlight=supra


Here is my unofficial take on what is a Supra, gleaned from my hours 
of research:


There were a handful of people building there own Supra before Kennedy 
got his into production, and there are many ways to skin a Drela 
sailplane to mix metaphors...


The Supras that were at the NATS this year (Kiesling, Lachowski and 
Barnes) were most-likely modified slightly from the Drela design for any 
number of reasons.  Mark likes tiny fuselages and some of his 
construction techniques are a bit too time consuming for mere mortals.
The basic parameters of the plane stay the same, the construction 
techniques often differ due to time/material/builder peculariaties.


AFAIK, the wing airfoils stay the same - AG40-AG41-AG42, and most of 
the Supras out there are bagged wings.  Mark's original Supra was 48oz 
and Kiesling said he has three:  two 58oz models and one 64oz model, all 
of them bagged wings.


As far as wingspans and such go, there might be some confusing the Aegea 
130 wing with the Supra wing.  The Supra wing is the evolution of the 
Aegea 130 wing (which Phil makes for the Mantis).  Mark explains the 
differences between those two wings on this page:

http://charlesriverrc.org/articles/supra/supra.htm

I've never heard any discussion on changing length of the tailboom, but 
the fuselages are often resized as Mark's fuses are tidy affairs with 
little wiggle room.  Also, I don't think I've ever seen or heard of a 
Supra that doesn't use that sweet little V-mount horizontal stab.


I have read quite a bit about spar and wing construction alternatives, 
though that could easily take days to sift through.


And finally...

There are a few folks producing individual pieces and parts for the 
Supra...  Les Horvath of CompuFoamCore.com had a fuse/wing/tail core set 
for sale and Bud Elder makes those v-mounts (in varying sizes!).  From 
time to time you'll see folks offering up Supra fuselages, but they come 
and go.  The bottom line is that if you really want to *know* about the 
Supra, go and read through the links I've posted, specifically the Yahoo 
group.


End of last fall, I put together an Aegea Mantis w/ a Luckenbach 
fuselage and Phil's Aegea 130 wing.  It's like a poor-boy Supra.  A lot 
of the same ideas, but different, and cheaper (and heavier).  One day I 
might get my homebrew Supra together.

I have read about the Kennedy molded Supra on the web page, but isn't 
that a Drela Design as well?


It seems when people talk about a Supra (glider) it could mean a lot 
of different things.  Different fuses and lengths, different airfoils, 
different wingspans, different wing construction (bagged or molded), 
etc...

[RCSE] Cabosil question

I need to buy some cabosil but don't know where to purchase it.

Is the West System, #406 colloidal silica adhesive filler the same stuff as 
cabosil?

Thanks,
