Rudder Mod,
I've lightened up the rudder . Covering came off easily and with the
use of some heat the clear plastic did not separate from the white
base. I also tapered the entire rudder , Bottom app 11 mm top 9 mm .
This will match a little better with the Trailing edge of the fin |
Heres a shot
of the face of the winglet that matches with the wing tip. I've marked
up the surface a bit and will add a piece of 2-56 rod in the other
alignment hole |
Wing end
I have cut away some of the film to reveal the wood and
scraped the wood for netter adhesion of the epoxy.. |
Inside of
the pod, battery takes up quite a bit of space, I may add a new rudder
servo tray and cut out the underside of the existing one to slide in
the battery. We'll see! |
Here's the
rebuilt rudder , newly covered with Monokote and I've taken a servo arm
and used it for the rudder arm.
I also drilled up through the center of the Rudder Arm into the rudder
and glued a piece of a skewer in , this should help to hold things
together. I 'm placing the rudder a little higher on the fin to avoid
the lower trailing edge being struck on landing.. As a result I had to
trim off the top edge to allow full movement of the elevator
surface.... The " new
rebuilt rudder" weighs 20 Grams c/w control horn, a weight
saving of 15 Grams!
This should allow me to save 45 Grams
(app 1.5 oz) of additional nose weight. As I'm
adding a
motor I anticipate the furthest forward I can go with additional weight
is just in front of the front servo mount bulkhead... |
A Cradle,
without it, I find the fuselage is always laying somewhere and only
subject to damage..
This will allow me to work on things during the build and I'll be able
to use it to transport the plane to the field..
A Handy Gadget |
New servo
tray with rear support, The Rudder servo is going to move back. Made
them out of 1/8 balsa, adds about 7 Grams weight. |
A shot of
the Servo Tray set in with the servo. The battery will sit on
top of the old servo location. Quick and easy location and
leaves me more room up front for the power plant! |
The wings
are different weights , left wing 330 Grams, right wing 360
Grams.
The difference can be seen here with respect to the balance
points, about 1/4 " in the difference |
The missing
30 Grams, in the form of a steel blade guide from a band saw...
This is where it would have to be, wing root to tip
dimension. I wasn't even going to attempt to place it Leading edge,
Trailing edge...
Anyway after all this I decided my flying skills are not that good,
that I'm going to notice the difference in wing weights... |
Gluing on
the winglets, I placed the wing leading edges together, on a line
parallel to the table edge. I weighted down the trailing edge on the
inboard ends and then placed my chess set box up against the winglets
perpendicular to
the leading edge centerline.. Hope it works...? There glued together now |
Scorpion
3020-14 and 55 A speed control compact and easy to program |
Closeup of
the motor and
mount, 5mm shaft to 5 mm thread prop adapter came with the motor, I'll
be using a 6 mm adapter for the larger aeronaut hub |
Alignment,
preparing to mark the nose.
I lined the center of the leading and trailing edge parallal
to the table.
The graphite rod was placed through the tube so that it was
protruding equal lengths on both sides. I then set these rods
as well so the were equidistant from the table..
|
A couple of
machinist squares clamped together to verify the measurements.... |
A shot into
the fuselage looking rearward . I placed a 4-40 rod through the forward
incidence holes for the wings, and as can be seen the oval bulkhead
does not line up well .. No doubt, its primary function is to
add
some strength. |
I used a
piece of 1/16 " or so aluminum and cut a 40 mm hole into, to mark the
nose for the aeronaut spinner |
Heres a shot
showing my plan to mark the nose cut line
perpendicular to a line through the leading and
trailing edge of the wing. |
Another shot
, again two squares clamped together.. I also scribed a horizontal
line, on the hole template, aligned with the center of the hole This
will give me a reference to measure from the end of the wing rods too.
No right thrust planed..
Since flying I have added about 1 - 2 Degrees of down thrust, and find that the plan doesn't pull up as much under full power |
Heres the 13
x 6.5 aeronaut Cam blades , collet hub and spinner |
Heres the
mark, it looks accurate and hopefully with the little bit of
preparation I made it will look and fly OK when finished |
Motor
bulkhead installed, I glued a couple blocks in in front of the
bulkhead. I'll go over all the joints with fiberglass later |
The
horizontal tail. I've made a template to mark both sides. I will cut
out these sections and recover in an attempt to save some ballst up
front . After removing all four sections I added a couple of
ribs, and recovered . New weight 85 Grams, 20 Grams less then
original |
The rebuilt
horizontal tail with Monokote patchs. I'm happy. 2 hrs work and
hopefully a saving of 60 Grams of ballast.... |
Canopy taped to base pan ,
I used GOOP, had good success with it on another project.. I spent
a considerable amount of
time
trimming base and canopy, it's so easy to cut to much off.
I also fashioned a spring retainer latch for the leading edge, I didn't
like the idea of using a screw.
|
Elevator servo cover,
fashioned from some 1/8 birch and a couple layers thin ply, I wasn't
going to be happy using the
supplied covers.
|
A couple of
pullers I dug out, getting the adapter off the motor is a bit of a
bugger.
Neither of these work, I'll fashion one from a piece of 1" x 1"
aluminum later. |
Aileron servo cover frames
|
Aileron
servo cover, still have to add the pushrod exit covers . I'll
try and use the plastic ones supplied with the kit. I've decided to use
the Hitec HS85 MG servos for the ailerons.. |
Elevator
cover in place, HS65 HB Hitec servo fits in nicely.. |
Heres my version of a Lost
Model Alarm, actually called a Slope
Sheppard, I believe
I had lost a
plane once and it took me hours to find and I walked by it many times.
Maybe this beeper will help the
next time
|
Close up of
canopy latch. I'm happy. |
Heres a shot
of the canopy in place, it slides nicely under the spring latch at the
front, and then held down at the back as per plans, with the supplied
hook and a rubber band. |
It all adds up

Prop Adapter Puller
Had to make one, these collet type
adapters are just to fragile to be pulling with screwdrivers and pliers
I
used a length of 1" Dia, about 1 1/.2" Long, aluminum rod, bored in one
end 5/8" Dia. and tapped the other end for a standard M8 bolt
All the cutting was done with a hacksaw and a little bit of filing and
I was finished.. I'll clean it up a bit with a finer file and some 400
Grit paper and add it to my tool collection...
1 hour or so of work and works like a charm!

Update April 21 2008
This plane flies great. 25 minutes of
flying accomplished quite easily ...
Stll looking for some of that elusive lift, no doubt, experience, and
launching with windier and or sunnier conditions can only help |
After
some 2 Hrs of flight time I have done a little work .. I've decide to
add two pockets for nose weights , one on either side of the motor..
These allow me to add and remove my 1/2 inch nuts a little easier, and
I will require less weight when I add the Camera
|
A shot of my vertical fin
Gusset mod.. I hope this strengthens this area up enough to prevent
further cracking... |
| Thought I'd post a couple
picture of my flying field! |
View looking north, I'm
standing at the edge of the woods. North -South runway is straight
ahead in center of picture, darker green area... |
Here I am standing on
Grassy Knoll looking east.. This is where I toss the ASW 28 from.
I can toss from here for a North, North -East launch or a Southerly
heading launch.
Once I'am airborne I walk forward toward the flag and picnic table and
stand there while flying ..
The flaf is at the intersection of my runways a good
spot to see all ends of the runways for landing! |
Heres a shot towards the
West, straight ahead the Grassy Knoll from where I toss the
ASW28 |
A shot looking South ,
runway is darker green area in image, at center. Far treeline is extend
of my Southerly range when flying base leg for approach with winds out
of the North... |
Update June 2008
Haven't flown in over a month, waiting for a wing rod from the good folks at Hobby Lobby...
Thanks Jay
Lesson learned though, when ordering on-line, ask for stock and
delivery status, or you might be surprised and or dissapointed when
your order doesn't show up in a timely fashion!
Update July 2008
Flying Again!
August 7, 3 PM 10 min flight, Cloudy Started to rain Landing to South East
