Author Topic: Bill Wilson's New Beauty (Read 4532 times)

Bill Wilson had his new airplane at the Gleason's Fish Fly.

Bill is one of the top flyers in the Dallas-Ft worth area. He is very innovative and has developed methods for molding fibre glass and carbon. Along with his brother he does painting and collision repairs and custom work on race cars and show cars.

Bill has come up with many new methods of finishing our airplanes. This airplane is an extension of his work with large radial cowls, and with flying stabs. From some angles and attention to backgrounds the airplane looks like a full size airplane.

Don't ever tell Bill that something can't be done... he will find a way.

Bill does not participate in the forums and I don't think that he has been to a Nats, so most have been deprived of seeing his creations. He would be a minimum of a top 10 Nats competitor.

A modern beautiful "Galloping Comedian". Nice. I love open cockpits, round engines. Too bad only one wing.

I have to agree with Ty. I just love the looks of the round nose and open cockpit designs.

Great looking plane.

Great shots Tom.

Beautiful. Did a great job. Kudos.

White, black and red is popular, offset by a tuch of gray. I like it!

Havn't seen a "flying stab" in years. I would like to see a mechanical.

Outstanding!!

You'll have to send Bill a link to our comments or he won't see them.

His stabilator construction technique is very interesting at the pivot point. Really a great approach as well as ditto for the rest of the fellows' comments.
I tried a stabilator many years ago, but the ship was way too heavy to really prove yes or no to the effectiveness of my design.

The plane also has an Evolution .60, centrifugal throttle control and internal muffler, not too run of the mill... and it actually works!

Thanks Tom.....really cool. So how well does it fly with the stabilator and low wing?

Thanks for sharing those beautiful shots, Tom. What a great, innovative design! Beautiful work.

Some more pictures. It has a internal pendulum to control the throttle, you can hear it working when he flies. Bill says it is not quite working as well as he wants, yet.

Igor Burger had one of those and should have some ideas on the topic. I am not sure what the "rest angle" should be, for instance - do you only sense the centrifugal force (parallel with the fuselage centerline at "neutral") or cetrifugal force and fore/aft acceleration (say a 45 degree angle at "neutral"). I don't know the answer but that seems like part of the question.

Amazing.

Tom, your shots are excellent!

Beautiful! I have seen his work first hand and he is quite the craftsman.

I think the rod can be adjusted to position the weight in an arc that could go either way, experimenting to see what it takes. The throttle stops before half way opened with plenty of power. If you know Bill, he will tinker with it until it works just how he wants it! It definitely moves in flight though as you can hear it change in maneuvers.

I sure would like to know more about this centrifugal throttle control! I'm having trouble trying to figure how it works, considering the model experiences + and - G-forces, certainly overcoming the force of gravity.

Igor had one described in some detail on SSW. Of course the most obvious idea is to hold the lateral acceleration/line tension constant. However, you can put some lead into is by mounting the swing arm at an angle to that it also senses the fore/aft acceleration, which gives you some input from the rate of change of the speed. When you hit the controls, the arm will want to swing forward pretty drastically, for example, because of the suddenly increased drag.

If you had a second pendulum, you could also sense the up/down acceleration and get something like the jerk or at least synthesize it with the fore/aft acceleration to get more lead or both directions.

This is what I figure Igors 3-axis accelerometer electric motor controller is doing. This is pretty much was was predicted as the end result of electric motor control about 10 years ago, no you have an infinitely dialable and perfectly repeatable Fox 35.

Yes I had centrifugal pedullum in model may be 30 years ago, but it never worked well. It was too slow and and it rather accelerated in windy conditions instead of braking.

FLOYD CARTER · « **Reply #19 on:** November 09, 2013, 10:29:53 AM »

Isn't "jerk" the 3rd derivative of position? (I've never had occasion to use it in any dynamics problem)

Igor, I think the problem may have been the severely corroded glow plug.

I think it causes flight attendants to spill coffee.
