*****Skyote #88 gets Bronze Lindy for "Airventure-Oshkosh 2016 Plans Built Champion"******

October, 2007

Welcome to "Skyotelog", the build record of Skyote #88. I assume that you are familar with the Skyote biplane. If not, you should visit http://www.skyote.org/ for a complete introduction to this unique but elusive biplane.

The posts are presented in reverse chronological order (newest first). Or you can click on one of the "Labels" to see all of the posts concerning a specific topic. Click on any photo for a larger image.

All my building experience is limited to Van's RV's so I have no experience with building tube and fabric or "plans building". I have much to learn so take everything I write with a grain of salt and reasonable skepticisim.

I do not intend to follow a "traditional" path for the construction of #88. I intend to employ low level technology and $ to reduce the construction time and difficulty where possible and practical. By low level technology I am referring to CAD, laser, waterjet, CNC. For example:

  • I have purchased a complete wing spar kit from Jerry Kerr.
  • A rib kit from Mr. Bartoe.
  • Brunton Flying Wires and Drag wires from Harvey Swack.
  • CNC profiled tube kits for the fuselage, tail feathers and landing gear from VR3.

In addition I have converted all of the wing fittings, brackets, links, lugs etc. to CAD and had them cut by water jet. I have designed a laser cut wing spar drill template/jig which positions the five spar components so that all of the holes can be drilled in a complete spar as an assembly. I plan to continue converting as many parts as I can to CAD so that I can reduce the "hand-made" components to a minimum.

Note: As of June 2015 I have over 100 CAD files which provide 600+ water jet cut parts for the Skyote.

While it takes a little time, converting the design to CAD is a great way to truly understand the drawings. plus a huge amount of information has been extracted from the rather complex drawings. This can be a great help to others in understanding and interpreting the design.

The Skyote is uniquely suited for conversion to CAD in that a "computer" was used in it's original design. I have read that Mr. Bartoe used a HP calculator to "compute" the design and dimensions of the Skyote. The plans show all of the critical dimensions to three decimal places for X,Y and Z axes.

Amazingly, when I put the design into CAD the resulting 3D models agree with Mr. Bartoe's thee decimal place dimensions about 99.9% of the time. I have found one discrepancy but less than 0.030"!

If you want to build your Skyote as cheaply as possible, or if you enjoy handcrafting the same parts over and over again then my approach to building is not for you!

If you want to build your Skyote in the minimum possible time with highly accurate parts then this approach may be the answer. I personally get a lot of satisfaction out of organizing the project so that it can be produced accurately. Hopefully some of this work will prove useful to others in the future.

Final Paint Choice ???

With fabric covering soon to commence, I have been forced to make a final choice on color and design for the paint scheme. I stumbled across an image of the beautiful Pitcairn PA-7S on the EAA site. I think the black and yellow scheme suits the Skyote well. The Marchadier and Bridges planes already sport the Pitcairn logo so I am going to do something a little different there.

I decided to deviate from the PA-7 scheme by leaving the vertical stabilizer black rather than yellow. I think it makes the airplane look a little longer and also makes a good presentation for the Skyote logo. In regards to the logo, I think I will modify the standard logo with a surround that includes "Skyote Aeromarine".

I have a set of Matt Lahti's carbon fiber Cessna 140/170 wheel pants. The look pretty good on the airplane but I haven't decided if I will use them or not.

The O-200 Is Here

The new Continental O-200 came today. I have included some shots of the engine still in its shipping crate an well as some after it has been hung on the engine mount. Looks like it is going to work out just fine. I was relieved to find that the engine mount lined up very nicely. The biggest challenge will be designing the exhaust system. I hope to have a 4-into-1 system with the collector exiting out the bottom of the cowl just in front of the firewall.
