Build Log

Beechcraft Starship, flying and developing


Beechcraft Starship. It's my plan to build and try to fly one of these in the amateur, multi-engine class.

A beautiful, innovative plane, the brainchild of Burt Rutan, it was a commercial disaster. 53 were built and $300m was spent on development. Only a few were ever sold. In 1989, the price of one was $3.9m, similar to a Learjet, but it was slower, noisier and less efficient. The pusher prop configuration was a major factor in this problem, for roughly the same reason as an electric powered Zagi makes such a lot of noise, I think. Propellors work best operating in a nice clean airflow, not behind the wing. But I'm sure it's not that simple.

Anyway, my first step will be to build a concept tester. A canard model adapted from my old Slinger flying wing. Just to see if I can fly one of these beasts. Hopefully I will be allowed, by the rules and by my lovely new wife, to try this before the 1 December. Oh! and not to mention my current Mosquito project, going very slowly.

Many thanks to Mike Scratchnhover for getting the steam up to enthuse us all in this new contest. And good luck to all the competitors.

Nick

2016. After 7 years of flying and enjoying this model, here are the details:
Incidence: inboard main wing: 0 deg
wingtip: -2.3 deg
canard: +4.8 deg
Thrust: -2.3 deg
The prop hubs are 350mm behind the CoG and 50mm above datum.
I can't claim to have set out with exactly these figures in mind, but it all seems to work like this.

Wing area is 530 sq" (34.2 sq dm)
AUW is 59 oz (1.67 kg)
16 oz/sq ft (49 g/sq db)

props are 7 x 5". Battery is 2250 3S1P
motors are Thumbrun 2830 / 14, 1600kv, weighing 56gms each.
combined max power draw is 450watts

In case you'd like 2 build one, you'll need the PDF files: They are actual size, B&W. Each one requires 2 sheets of A0 (33.1" x 46.8")

Good going, Nick. The Starship is one of my favorites. The innovative design makes it a standout already.

Do you thnik you'll go with retracts, or is that a given?

My buddy's father was a VP in Sales at Beech in the early '90's and I had the chance to fly in a Starship. We went up early in the morning and had a nice 30 minute flight. It was great needless to say. I still remember the short takeoff and steep climbout. Good luck with the build.

Thanks for your brilliant photos Kato.

Yup, retracts for sure. Of course, the more I think about it, the more I think maybe it would be possible to organise flaps linked to the variable sweep canard. Crazy fool! - it's all very easy inside my head!

I've got to walk before I run, run before I fly and fly before I can land safely.

If it turns out that flying the concept tester is fairly benign then I can start getting ambitious with the cunning features. I'm not even sure that my Tx has enough channels. There are 6, but number 6 is usually used for the left aileron, 5 for the u/c, 4 for the rudder, etc.

I think I'm going to want rudders to manage it on the runway, link those to the steerable nosewheel. P'raps the flaps etc can operate on the same signal as the u/c. hmmmmmm

As I recall there was some prop noise on takeoff but it was overall a smooth ride. The cabin was very upscale with leather seats and a nice bar.

Here is a link to a guy who's got a real Starship - NC-51. He says "On the ramp she gathers more stares than a girl in a bikini." and "A Starship pilot feels as safe as babe in his/her mother's arms. The machine feels like the melding of a magic carpet and a Mercedes Benz."

Well, if I can get mine flying p'raps I can bask in some reflected glory

Yes, I saw that one too.

If it was easy, everyone would do it!

I wouldn't have thought it possible without these people

Nick, at this point I am utterly convinced I made the right choice in not joining you in building a Starship! Had I found those threads, I don't think I would have even considered it...well, ok...I would have considered it because the plane is so cool.

Good luck to you. Let me know if you need any additional reference photos. It's very easy for me to get to one.

Nice to have a real one a half hour away, "just in case," eh, Kato?

Life's good when you have the everything from a Bleriot to a SR-71 a short drive away, not to mention the venerable Spruce Goose.

I know...brag, brag, brag...sorry guys. I'll shut up now.

The Beech/Raytheon corporation in Gluckstadt MS (Just north of Jackson) has been flying a Starship for several years. You definitely know it when you hear it overhead. Haven't seen or heard it lately, might have to inquire of its status.

I think the Starship would make a really cool model. I've been involved with the ARF Long-EZs and the Quickie. Canards are definitely a head turner.

"Since 1995 Bob Bass has logged 1,900 hours in Starships as a corporate pilot for Vertex Aerospace in Madison, Mississippi. Its a wonderful airplane to fly, very maneuverable and plenty of power, he says."
