The demo plane challenge

[cantab]

Followers of DasValdez may know he spent this evening streaming about the demo, which gave me the idea to try and make a plane in it. I then thought it would make a good challenge for people to try.

Objective:

Using only the parts and features in the current KSP demo (0.18.3) build a plane that meets the "Wright standard" of powered, sustained, controlled flight. Safe landings are optional.

Rules:

If you're using the demo, it's simple enough, just build a plane.

I will allow entries done in the full game, for convenience and game performance issues. However, you must ensure you do not use features absent from the demo as well as limiting yourself to the demo parts. In particular this means no mods full stop, no tweakables, and you must build in the VAB and launch from the pad. I'll grudgingly tolerate full game SAS usage; keep in mind it is very different to the SAS in the demo.

Not sure if they're even in the demo, but no gravhack or fuelhack obviously. Glitch powered aircraft are allowed only if done in the actual demo because glitches change with versions.

Minimum entry requirement is a screenshot of the plane in flight.

No formal scoring, just meet the requirements. But you get extra bragging rights for doing cool stuff.

Demonstration of possibility

Here's mine that I knocked up: https://flic.kr/p/p4gZDu

Built in the actual demo. Launched atop an SRB. Once free it flies OK, using about 1/3rd-2/3rd throttle and controlling it on fine controls and pitch trim, no SAS. It's not a great plane: it tends to drift left or right, doesn't like going much above a couple of km, and has trouble pulling out of dives if it gets in one. Landing without using the chute was not successful.
