From: "Jeff Nibler" July 28, 2002
Hi Ray, I'm sure you're busy with the Nats and all, but I just had to
share something quick with you that I'm sure will make you
smile. Today at my club's Hand Launch Contest (PASS), I placed first
out of 12 with my bone stock LilBird2.
I was the only javelin launch out there and was up against some stiff
competition (such as an Xterminator Pro and some really good pilots).
Just figured you'd get a kick out of that. I'm probably going to be
ordering another one from you soon, as my wing is about 90% packing
tape.

This e mail did make my day, Jeff has learned that with a good HL design and practice, the Lil Bird 2 is very competitive. Imagine the potential contest success Discus launching a Lil Bird 2. I'll find out at next years
Wood Crafters 2003 HL event. This event will host woody HL designs only and launching can be by Javelin or Discus launching (sounds like the OLYMPICS). Maybe it is time for a beautiful Lil Bird 2 glass fuse.
Thanks for the e mail Jeff.

This all wood kit can be constructed very quickly because of the super accurate
LASER CUT PARTS and Ray's design engineering that
reduces construction time to a couple of weekends.
All parts are laser cut and the 1/32" balsa wing sheeting is pre cut. The fuse
formers and sides are self aligning tab-slot design
to further reduce building time and allow accurate construction.
The rudder is tabbed and the stab is slotted to create a super strong and
accurate assembly. Both rudder and stab only require
sanding the edges round and can be glued with CA for FAST assembly. Plans are
CAD drawn and all hardware is furnished including a
tow hook.

You won't believe it when you fly the LIL BIRD 2. It is a very attractive
glider and looks fantastic in the air, but the superior
flight performance is truly unexpected by all. The S3014 airfoil will float in
the lightest of late evening lift or fly in very
windy conditions extremely well allowing the LIL BIRD 2 to spec out down wind
and return. The wing is very strong and can easily
be launched from our world famous Mini Hi Start, plus the wing is not prone to
tip stalling and it is built without tip washout to
further simplify construction ease.
The Lil Bird 2 has been launched Discus style with good success. This is being
done to an unaltered LB2 without beefing up the
structure. The method is to have the right wing tip on the ground surface,
holding the left wing tip with your right hand covering
the D - Tube section and your thumb on the bottom spar, fingers on the top spar,
start your spin gradually, raising your right arm
/ hand as it gains flying speed, release with an up ward flick of your wrist.
This requires a preset on the rudder to conteract
the roll during launch. Start this launching procedure by gradually increasing
speed as you become accustomed to the style of
launching.
You can modify an existing LB2 for Discus launching by cutting away some of the
bottom wing sheeting where you are grasping the
wing during launch and fill this area in with white foam.
What makes the LB2 performance so great ? Well, sailplanes are all about
airfoil, but also plan form and flying weight and CG
location.
If you build the LB2 right out of the box you will be very happy with
the performance, it will be superior to any other
wood glider you have flown.
Many of our LB2 customers have reordered second and
third kits and asked what, if anything, could be
done to kick the performance up another notch. The following is what I do to
give the LB2 all the competitive edge it can muster.
I can build a LB2 to weigh 6.8 oz in the air, but have to add ballast when
conditions get robust.
1. The wing is built stock with one coat of oil based Polyurethane on the
sheeting surfaces that is immediately soaked off with
Bounty paper towels to a point where the wood shows no signs of being wet (this
is done to all surfaces). The open bay area is
then covered with clear .0015 Mylar that weighs .0009236 oz. per sq. in. A 1000
sq. inches of this film weighs .9236 oz. Apply
the film as you would any other heat shrink covering. The ease of applying this
film is the best I have ever worked with and I use
it on other fully sheeted larger sailplanes. Wings are attached with two nylon
bolts.
2. The fuse weight is reduced by drilling one inch holes in the 1/64 plywood
doubler. Drilling holes in the fuse formers. Running
the antenna from the Rx forward to the nose block and back through a straw
located in the center hole of formers F3, 4 and 5 and
putting the excess between formers F2 and 3. Never let an antenna hang outside
the sailplane. Cut the formers and bottom fuse
sides to narrow the outside fuse width to one inch and height to 1- 7/8" at the
forward wing bolt location to reduce drag.
3. Sand a taper into the elevator and stab to reduce weight and drag.
4. Four 110 Mah flight battery cells in tandem, micro servos and 555 Hitec Rx.
The LB2 will balance with the flight battery
located a half inch behind the nose block and the servos are in tandem behind
the battery. Former one is omitted and the 1/8 sq.
spruce rails are located from approx. one inch aft of Former 3 to 1 3/4" forward
of the wings leading edge.

The LB2 IS A PROVEN CONTEST WINNER AND IS ALSO GREAT ON THE SLOPES.
