Avro type F. historic plane who was the first with a closed cabin.

[leaded50]

im stuck again, and bored in bad weather..... Another build (a quick one) feeled ok.

Avro type F from 1912 ! nobody said it has a beautiful design but a design easy made "authentic" by foamboard.

A few modifications on the undercarriage will be done for better install of eg, battery(perhaps). And made as approx 750mm wingspan who gives a length of approx 550-600mm. I believe it will be a lightweight good trainer though.

main parts of fuselage cutted.

begin glued together, seen from belly:

That plane is so ugly, I’m surprised the ground didn’t repel it.

 

[leaded50]

got tailsurfaces on, and forward center top section

. The rudder is mounted with two hingepins glued in.

 

[leaded50]

fuselage can already be painted...

 

[leaded50]

the original plane, who was made only as one prototype chrashed with "mother earth" in a testflight. (not the first testflight though )
The thought was a better "comfort" for the pilot, that shouldnt needed sit in a open cockpit, and get his visibility soiled by engine oil leaks, exhauset gases, eg. typical from such engines of the eara.

Its "teardrop streamlined shape for speed" you know with its 35hp engine and max speed of 65mph... .

Fascinating!!

 

[leaded50]

its been nice with see through windows, but when making it as "mini", thats not a option, because would needed much reinforcing. Could been done though with right materials in house (that aint ) Started 3D print the dummy motor parts.
Im not even sure where to place battery yet, and hatch for it.. It seems it can be tailheavy though as typical most WW1 and earlier models.
The undercarriage wheel/skid struts seemes can make it more complicated for a hatch at belly...
A 2208 (1450kv) motor laying around is mounted at firewall already.

Nice video presentation of the plane @Baron VonHelton

 

[leaded50]

coming alomg quite good. A easy build till now.Got a reworked 3D print dummy motor. Its the landing gear with wheels and skid who needs extra attention...

 

[leaded50]

done first glidetest now, and if rudder is enough surface, this gonna be a very nice easy trainer! (yes, it was already made it a bit higher)

I think it had wing warping roll control. In hindsight its kind of amazing ailerons took so long to become standard. Were you planning on making it 3 channel?

I think it would have been less ugly if they wouldnt have put the trim around the windows. Where is the door?

Correct, it had wing warping for lateral control . Im gonna make just as 3ch. The "door" was the top windows was a hatch to open/close.

Aileron concept was patented in 1868 by British scientist Matthew Piers Watt Boulton .
The name "aileron", from French, is meaning "little wing". Ailerons were not used on manned aircraft until they were employed on Robert Esnault-Pelterie's glider in 1904, although in 1871 a French military engineer, Charles Renard, built and flew an unmanned glider incorporating ailerons on each side (which he termed 'winglets'), From 1908, as aileron designs were refined it became clear that ailerons were much more effective and practical than wing warping. Ailerons also had the advantage of not weakening the airplane's wing structure as did the wing warping technique, which was one reason for Esnault-Pelterie's decision to switch to ailerons.
By 1911 most biplanes used ailerons rather than wing warping—by 1915 ailerons had become almost universal on monoplanes as well.

that was the history time

 

[leaded50]

well... plane is quite ready to fly!

what was the original idea/build plan?? A papermodel! And a 3D view drawing.
Differences is eg the fuselage is made in 4 parts (top sides,bottom) not as an papermodel. That way i get off the foamboard thickness trouble in planning. And in front at sides, half up, its plywood reinforcing at the sides. Then had good material to mount the undercarriage struts. Not a double wing, just one foamboard thickness, and not in three parts. With the measure of sides and top, it was easy make one former where color changes on the front.
By the way.. the rear stab is set inline to the top of rear fuselage, not as in picture here. Then it would got too much incident at wing relative to this angle.

Ah Yes! Fiddler's Green!! Go check out the Fokker Dr1 Skins! You might find a certain "Baron von Helton" submitted the skins!!

Yes, I am LITERALLY everywhere! ROFL!

out in daylight... ZTW 2208 1450kv motor, 30A ESC, (3S-4S) Auw with 1000mAh 3S battery: 440g

The red St.Georg cross on tail... is "prehistoric" English marking. At 1912 their roundels wasnt made yet, its said military used the UK flag though... The red St.Georg cross is a part of the flag anyway, and this was a not a military machine.
Weight distrubition get quite good, with the battery sitting nearly vertical inside in front of the wing. Hatch on top of fuselage at front. And good space for ESC /reciver under the wing, + the two servos into top of the sligthly dihedral wing.
The 3D printed dummy motor, is made by 5 cylinders, and a center "gearbox hub" from another file to fit loosely outside the el.motor glued to the firewall. Some extra driled holes for cooling.
Undercarriage struts/wheel axle are normal ss bicycle spokes, who is "sewed together at connections with thin ss wire, and superglued. Even the ski is sewed through with the thin wire to the struts.
And yes, it got more or less a aged look. The ligth creamyellow paint was a slooooow dryer, and with some handling before dryed fully, and airbrushing, + some use of a old rag when still a bit tacky, it lost its "brightness". Hey, at that time they still handpainted everything, even cars. And nothing of a one prototype was made "perfect"

a bit more from the history of the plane.. Closed cabin was a way for the pilot to let go not loose his view by the oil leaks and residues eg that all motors gave that time...well, he didnt get that trouble in his face.... but anyway the windows on this plane also got it, so view got anyway a loss .
The two round windows was possible to open and look out of, when the front cabin windows get to stained.....
