RE: Anyone have a maiden flight like this.
Here's one that's somewhat similar (though more of a tail-heavy case):

That's a shame. I wonder what he did to get the SR Eindecker so tail heavy. Mine is spot on with either the electric setup or Zenoah G-26 for power.

RE: Anyone have a maiden flight like this.
Chad, do you mean Bill's model? The EIII is just clearly tail-heavy (but luckily was able to "helicopter" down with little damage). It's harder to say what went wrong with Bill Thompson's Ansaldo. It seems like a perfect example of what people call "wallowing around in the air."
Bill's model doesn't look like it wants to move forward through the air at all.

The Ansaldo had several bracing wires break soon after take off that allowed the wing to warp and move. It was just doing it's own thing. After landing, we could move the wing back and forth over 12".

The Ansaldo's right wing panels are clearly flexing, leading edge up, suggesting that the forward flying wire let go, and maybe one of the incidence wires. He did well to bring it down as well as he did.

RE: Anyone have a maiden flight like this.
I really think that big bipe needs more tail surface, I was always told 10 percent more than scale outline...and I would add some lead up front for insurance..
I think he is close ... or he could never have recovered it so many times.. And yeah , I have had a couple wild test flights like that.... shiver

RE: Anyone have a maiden flight like this.
If you check you tube, the second flight is posted. Search for "The Hoosier Dawn Patrol" or Sirpercy. All wires were redone, The fuse was reinforced and reconfigured for a larger engine. And , Billy added mucho details. The second flight was very much a success. With rigid wings it was very controllable. The first flight would have been successful had the wires held and the wings remained rigid.
The second flight is also posted on the Hoosier Dawn Patrol website
thanks

The Ansaldo is proof of the old statement that it is far better to be lucky than smart. Anybody building a model of that size and complexity in 14 days is an idiot and the flight is proof.
Sorry to say that but it is true.

I am impressed with the task of building it in 14 days from scratch, my hats off to the designer/builder.

RE: Anyone have a maiden flight like this.
First of all I should not of posted this because I did not intend it it to be critisim on the build or build time. Ive was more interested on problems some people have experienced on maiden flights and this one was an increduable recovery. He lost his wing rigging and the wings twistend a couple inches.......how the hell he brought it down in one piece is an increduable art of flying and I would be proud to have been capable of this feet!

RE: Anyone have a maiden flight like this.
It does look like it lacks directional stability. A short moment along with smallish area, especially on the fin rudder, is very apparent to me. I know there is a focus here on the speed at which this aircraft was created, but as someone who is in manufacturing for a living, Speed and quality do not go hand in hand. Something usually gets missed. This may have shown up in the design phase.
I wonder though what caused the crash? I would bet on the RX battery. That is always the thing that bites me. Or maybe something else that got missed?

Spoken like a true ARF builder.
