Aero-Fever / FlyFly ASW 28




This is how the plane arrived , I couldn't believe it, beautiful, even before I opened it, 


Unwrapped, only one corner was a little dented on the box, nicely wrapped as well with some 1/2 inch styrofoam, First Class ! I can't wait, how does everything look inside?


Box opened , first impressions, tickled pink, stunned. I'd never bought an ARF. All my planes were either built from scratch, or from a kit of balsa sticks and sheets....
Everything individually wrapped and bagged...
Is it all there...?  I also noticed where the top package, wings, was held into the cardboard packing in the right side there was a crease in the foam. Felt it and thought oh oh, not a crease in the wing ... Nooooo!.


Here's a closeup where the wing was set into the end wrap.... Fortunately not a mark on the wings .. A sigh of relief and as you will see, in the next picture .. Beautiful


Here's everything out of the box and unwrapped... Very professionally packaged... I wonder if all Arf's are wrapped this good....
Over all weights. Grams  (1 Gram =  .035 oz  )
Fuselage 390 G
Wing Left 330 G
Wing Right 360 G
Winglets 20 G each
Horizontal Tail 105 G    rebuilt  new weight 85 Grams
Rudder 35 G     rebuilt lightened  now  20 Grams

54.5 cm overall length 110 cm


The nose, and to think I'm gonna cut it off! My wife even thinks it's beautiful..
Well, as you can tell I'm beside myself, just can't believe how beautiful...
I've had a look at the rudder, and considering that some have posted regarding woosh , air noises etc.,
 I had notice that the rudder was quite thick. It  measures 13 mm at the top leading edge and 13.8 mm at the bottom...
The corresponding locations on the trailing edge of the vertical fin measure  9mm and 12 mm respectively... I think I'm going to fashion a new rudder corresponding with the trailing edge thickness. Should also gain me a weight saving..



Heres a picture of the glider which is being replaced by the ASW 28. A fine example of a Graupner Amigo II, I carried this home in the cabin of a plane some 30 years ago from Germany, it's was banged around, crashed rebuilt and crashed again, many times..
Originally it had a Cox/Sanwa 2 channel radio in it. It's too bad I haven't got any pictures of it in flight.
This bird now has a new owner and no doubt will provide many hours of happy sailing



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
Aero Naut parts I got mine from,
http://www.aircraft-world.com


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


 




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 flag  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...
