Flying machine
 
I've been toying with the idea of building a scale old-timer, perhaps a Blériot XI or the like. But then I thought, "I haven't got the patience to do a good job of it", and an actual scale model of something like that will no doubt be kind of a boring flyer.

So instead I thought I'd do a capable sport plane disguised as an old-timer :). It's going to be rather the same size & configuration as others I've made that I'm happy with, but the fuselage will be uncovered sticks; maybe a little wire bracing thrown in here and there.

I'm planning a symmetrical foam wing, about 42" span, and I've got a HURC 450 sport motor laying around. Should be able to fly pretty slow, and also do unlimited straight up when desired :).

Underway, more as things progress:

Cheater! :Q

More on the fuselage:

http://www.wsukes.com/temp/DSCF3142.JPG

The sticks are all hobby shop basswood (which was stupid ($!), 'cause I could have made my own out of spruce). Side panels are pine (about .050"), 1/8" & 1/16" birch ply for the front and back panels. Once the glue has cured and I've sanded things flat I'll add 1/64" ply gussets all over the place.

I've ordered some cheap, 2 1/2" WW1 style wire look-alike wheels.

Having fun with this :D.

dgjessing,

Very nice, I like your drawing, and the fact that you will leave the fuselage uncovered as sticks. …sometimes, I'm sad to cover my planes :red: …I really like the way all the work and detail underneath the covering looks.

coooool. will be watching.

Thanks, Forge :)

Fuselage gusseting completed:

Can't wait to complete the thing and spray lacquer on it!

FlyWheel 02-21-2014 03:01 AM

Looking very good, that is expert woodwork!

dgjessing 02-22-2014 12:17 AM

And the fuselage as of this evening:

http://www.wsukes.com/temp/DSCF3145.JPG

The front 2/3's or so of the top lifts off as a battery / receiver access hatch. The whole thing weighs 3.45 oz at this point.

I think I'm going to cover the eventual wing and tail surfaces with that ugly "taupe" packing tape. About the color of mid-90's computer cases - know what I mean? I think it will mimic the color of doped muslin fabric reasonably well. And I've got a roll of the stuff laying around :rolleyes:.

I'm also planning on making a facsimile of a 3 cylinder radial engine, to suggest an Anzani "Y" type. Unlike the Anzani powered old-timers, my plane will have about a 2:1 thrust to weight ratio :).

dgjessing 02-23-2014 12:46 AM

Got the first 2 of probably about 5 coats of lacquer on the fuselage, and cut the wing cores:

Oh, and the wheels came in the mail (not shown, they look good :)).

Thanks!

It's taking shape:

http://www.wsukes.com/temp/DSCF3149.JPG

I'm pondering different shapes for the wing tips & tail feathers, and where to put the "pilot" & rigging mast(s).

dgjessing 02-25-2014 12:10 AM

And here are the curves:

http://www.wsukes.com/temp/DSCF3151.JPG

Everything is just raw here, awaiting covering. Thinking about using a wooden prop :D. Still trying to figure out how to do a semi-realistic pilot figure and a rigging mast... Unfortunately my battery hatch's lift point is right in the middle of where all that stuff should be :confused:.

hayofstacks 02-25-2014 02:41 AM

Do the rigging on the back half, then mount the pilot on top of the hatch.

CHELLIE 02-25-2014 04:02 AM

You use foam for the wings and now you want realism?! :Q

Just joking with you, build's looking great. Have you thought about getting a hollow pilot figure (or hollowing it out yourself? You may be able to tuck the battery inside, I've read at least one Olde Tyme build where that was done.

Chellie: LOVE the instrument panel ROTFL!!

I'm talking stand back (way back) and squint "realism" :).

Here we are as of this evening:

http://www.wsukes.com/temp/DSCF3152.JPG

The cockpit & pilot are just sitting there (Mickey Mouse & the Mario Bros. guy are also in the running...).

I'm kind of leaning towards forgetting about rigging wires altogether. Not sure how much they would add to the visual effect, but I know they would add to the drag. I dunno...

Piling everything shown plus motor, esc, receiver, 4 servos, and a couple batteries on the scale we're at about 25 oz AUW currently - about what I expected.

gramps2361 02-26-2014 12:10 AM

Dave that looks great, and the tape you mentioned back a few posts looks good on the wing and tail feathers works great with the natural color of the wood.
I used to play that Mario's game with the kids, and sometimes after they went to bed.:rolleyes::) I vote for Mario even though it's your build and choice.:Q

dgjessing 02-27-2014 12:12 AM

Thanks gramps!

All electrical, control horn & push rod stuff this afternoon.

http://www.wsukes.com/temp/DSCF3155.JPG

I've gone with a different motor than originally planned after discovering that the thing was a bit nose-heavy. This eMax CF2822 weighs almost an ounce and a half less than the originally planned HURC 450. I've salvaged it from a similar size plane that was pretty lively, so I'm sure it will be adequate. Might not be able to do unlimited straight up, but that's OK :).

I'm not going to bother with any fake rigging wires.

I've got the ailerons working - rudder and elevator tomorrow!

dgjessing 02-28-2014 10:35 PM

OK, it's ready to fly:

http://www.wsukes.com/temp/DSCF3160.JPG

I went with the dog for the pilot, obviously. He just looks like he's having a lot of fun :). The motor looks better in person than in the picture - I'm pleased with it anyway.

The "dry" weight (no batteries) is 18.5 oz. 42" wingspan, 7.25" chord. 31" over-all length (tip of spinner back).

I wish I had taken it out to fly today - I went out with another plane but figured conditions would be iffy... But as it turned out, it was a pretty good day.

gramps2361 02-28-2014 11:21 PM

DG looks great, and I have to agree the pup looks pretty happy to be piloting a fine looking plane. I have had the weather trick me a few time,s and left the new plane at home. I hate when that happens.

With the storm moving in looks like sat. would be your only chance to fly.

Today I took it with me, and it flies great! :D

Sorry, no video - I'll do it next time.

I took off with everything set to low rate, flew back and forth a few times adjusting the trims, then switched to high rates and verified that it's pretty maneuverable :). I only flew it twice 'cause it was a bit windy and I didn't want to push my luck. I'm pleased!

CHELLIE 03-02-2014 12:21 AM

Congrats of the Successful Maiden flight :$ Your plane turned out great, We Need some Video, You Tease You, ::o :<: :roll: :D

dgjessing 03-02-2014 12:34 AM

Thanks! I shall do a video as soon as possible. In a couple weeks, probably...

gramps2361 03-02-2014 01:10 AM

I second that congrats on the successful flight. Like to see a video myself, but I know how tough it can be to recruit a camera person.
