Thanks Nomatta
So that is the 40 sized and you built the sides of the fuse down as a belly pan, and mounted the wings to the side of the fuse instead of just running it under the fuse with a belly pan below the wing, Very cool and beautiful work looks great, I forgot you originally did a 2 piece wing for the 40, Did you have to cut the wing down in length or did you just do the 2 feet per side anyway?

The 2 piece method I am employing is somewhat compared to how the Sig Something Extra uses. The only difference is I will be using nylon bolts instead of the eyehooks and rubber bands as the Sig SE method shows.

If you look at the small Twist 480 they use a 2 piece wing design as well. If they can get the workings to fit in that one I don't see how a .40 size would be harder.

22 1/2 inches per side, three inch wide fuse. Did it mostly as an experiment. Not really justified for a 4 foot wingspan.

Tweplica Maiden!

Well, the weather warmed up a bit around here in mid-Michigan last Saturday, so I flew my Tweplica for the first time. My camera man tried to get a good first flight video, but I had a bit to much elevator dialed in (actually, I just wasn't prepared for how agile and responsive the plane would be) and she bolted straight up into the air once she had enough speed. I freaked out a bit thinking my balance was off and it was tail heavy, but I recovered quickly and trimmed it out. It hardy needed anything. Maybe a click or two of aileron and elevator. It's well balanced; inverted flight only required a comfortable touch of elevator input.

I flew her three times and gotta say... I'm loving this plane. She's a bit squirrely in knife-edge (doesn't like to veer from being perfectly vertical), but that's more a matter of getting used to its flight characteristics.

All right, fair enough! I'll get the ACTUAL maiden footage uploaded and posted. It's nothing spectacular, mind you. Mostly me just cautiously taking her around for laps. I'll sneak in a landing vid to boot... Give me 24 hours. Hitting the sack now.

No problem I am just kidding around, but we would like to see it when you get a chance if you don't mind. Usually a Maiden flight has all the excitement in the voices and the way the plane is flying around lol especially if there is panic thats when its real funny lol

OK as requested:

The ACTUAL Maiden (The first part of the video is me just taxiing around for a while. Head to 1:14 for the takeoff) It was a breezy day, so there's lots of wind noise in the mic, sorry!

+10000 to everything Waldo said! Nice build, sharp covering job, and great landing. Love those 4 stoke engines...which one do you have on there and what size prop?

Thanks guys!

It's a Saito .72 turning a Master Airscrew 13x6. I have an APC 13.75x3.75 prop I want to try out on it though. But the current prop tows it around pretty nicely. Hovers well, decent top speed (though I don't need that so much).

I am going to put some black stripes on the underside of the wing. I didn't think orientation was going to be an issue, but at a distance... yellow and white in a bright sky aren't as easily discernable as I had anticipated...

If all goes according to plan, wait 'til you see what I re-maiden this afternoon. Details if/when it actually happens... =)

A re-maiden flight of a Funtana S-40 I restored this winter. It was in rough shape and headed for the dumpster. Stripped it down, made all the repairs, recovered it with a custom design, and threw a Saito FA-100 up front. The engine is way too big for the original cowl. It was windy again, so pardon the mic noise. (Jump to 1:01 for the actual takeoff.)

Here's the landing of the re-maiden flight:

Then on the second flight I had a deadstick right in the middle of a vertical climb over a farm field only maybe 75 feet in the air. Unable to make it back to the grass, I turned it into the stiff breeze going that day and floated it down and landed it right on its belly in a field.

I've already got it repaired and ready to fly again. It was a lucky and easy-to-fix clean break behind the cockpit:

Yeah the twist like to break in the same place.
Boy that scratch built twist sure flies nice. I'm sure you'll see she is great for flying in the wind.

Hello all,
I'm not sure if this has been asked or not, but how do you guys think the Tweplica would do with a sheeted foam core wing? I recently got into foam wing cutting and want to try different wings and airfoils.

Thanks,
Shawn
