Mike Lachowski has some nice netted ones especially for winches.

I looked and looked, but couldn't find a 12 foot nail.
You supply suitable stake for your conditions, a 12' nail is good for hard
packed conditions, a spiral dog stake is required for softer soils or wet
conditions

If you are planning on flying F3J or F3B I would suggest looking for 5dm2
size parachutes with welded rings or better. You dont want them to be to
big.
All dealers that have models from Samba (Brio, Superior, etc) www.f3j.com
can supply them. www.f3x.com , www.specdoutsailplanes.com , etc.

HI Guys,
New RTF Hammerhead ODR Plane for sale. The plane is brand new (flown only for
two trim flights) and comes complete with Hitec HS85BB Servos on Ailerons and
Elevator, JR 600MA Extra Battery Pack and Switch. The plane weighs in at 25.4
oz dry and I have a ballast system made up that
hi all,
I've been asked this a few times, and I give my opinion,
but i want to see what you guys have to say.
What gets better mechanical advantage, top or bottom
driven linkage, and how much does the drag of bottom driven
really effect things, if any ?
My vote goes towards bottom driven.
I can
For what it's worth, some years back a German modeler, whose name I can't
now recall, and who apparently had the means to evaluate it, determined that
4 covers over exposed linkages (clevises, rods, horns, etc.) added 5-10% to
overall airframe drag.
This was of interest to me since I was then
I like bottom driven flaps and ailerons for various reasons. According to
Dr. Hepperle a properly faired set of 4 linkages on the bottom of a wing add
around 3% total drag to a typical F3B airframe. You can go dig around his
website and find a number of interesting tidbits.
Dave,
I would have to say bottom-driven gives the best advantage. On the Icons,
this has proven itself time and again. However, I would add that I have
assembled a number of planes lately with top-driven linkages, including a
Tragi 705x and Graphite Standard.
In actual use, I found the top
Rob,
That's an interesting page. I especially like the drag summary at the
bottom. For a mid Cl the airfoil is responsible for 55% of the drag,
induced drag is another 20%, the fuselage is about 18%, the linkages about
3% and the stab is worth about 4%.
In almost all cases the linkages on the
I was browsing through a German book on gliders used during the war and
came across a couple of interesting photos. One claims to show the first
aerotow attempt - both towplane glider (definitely not a sailplane) would
be interesting topics. The other shows a DFS 230 troop glider with a
I'm selling for a friend a brand new never used Royal Evo 9.
Comes with Synthesizer, data cable and all the goodies that the new
radio comes with.
The first $460.00, plus shipping takes it.
No Pay Pal until I clear it with him first.
Thanks, Ron Widel

You know it's kind of funny. We spend all this time trying to build the
cleanest plane possible with internal linkages and as little drag as
possible trying to get that last bit of performance. Then we strap on the
large drag inducers know as skegs to stop us on landing. What's wrong with
this
Thats good Ed.:-)

This past weekend in St. Louis was as nice a soaring weekend as I guess I
have ever seen, it was not give me air, but just three beautiful days.
Friday was a brain dead day for air, we flew some HL and set a couple of
winches for fun flying. I wish that we would have been somewhere where XC

A set of alkaline batteries will last a long long time in a two channel
glider. Unfortunately I forgot they were alkaline and charged them into
giving up the ghost . The liquid from them destroyed the receiver and
probably the only servo in the fuselage. I had no fire but the fuselage

Can any one suggest a source or sources of heavy wingrods suitable for

when the lift is strong and at the other end of the field.

Well, considering that they're called alkaline, my guess would be a base.

I was wondering if anyone else has the Estrella with the new airfoil if
so what C.G. and tow hook location are you guys running. Right now Im
running mine at 4 9/16 (116mm) from the L.E. and it seems to be pretty
safe so far. Havent launched it yet because it doesnt have an
adjustable tow
