Re: Tail Spruce Strips

I too had a rabbeted recess. Hopefully you'll be able to see in the picture that, while the gussets lie flush, the capstrip doesn't quite fit flush in the rabbet. I used a hand plane and sanding block to feather the capstrips in so that there would not be an abrupt step for the fabric to negotiate. ...

Re: Glide Ratio

Oscar, I suspect the V speeds may vary a bit across Piets. Recall mine has an extra 18" of wingspan (9" per side). I found glide and climb tests to be lots of fun. They also helped sharpen my flying skills. For each test, I set up the glide a couple hundred feet above 7000' and would glide at pre-de...

Re: Glide Ratio

I used Lowry's Bootstrap Approach to Aircraft Performance when doing my Phase One testing of NX313KB. I highly recommend this resource. I found the best glide (Vbg) to be 57 mph. The glide ratio at that speed is 7.8 to 1. You can find documentation of these flight tests under the "Files" tab of the ...

Re: Still new and nuts on nuts

You'll want inspection holes for places that need to be lubed or inspected annually. You may also want to glue in, during your original covering job, inspection rings and doilies in several places that might need to be opened for a future repair. For example, my pitot tube goes through the leading e...

Re: Tail dimensions on plans

John, Your 3/16" is correct. Blame it on a senior moment or just a wrinkle in the math multiplication universe. Are those the same thing, anyway? Yes, if you route out 3/16" from each side of the T-beam you will have removed a total of 3/8". That will give you a T that is 5/8" on the base of the T. ...

Re: Tail dimensions on plans

John, Those are the dimensions that I used. It all begins to make sense when you start assembly the pieces. You end up with a bit of contour to the horizontal stabilizer. The handwritten 3/16" on the main beam is not quite right. Each of the sides of the main beam should be routed down 3/32" per sid...

Re: Wing Rotisserie Operational

Here's how I handled the outboard wing rotator. I drilled a hole through the wing bow where the weight was approximately balanced and then installed a T-Nut on the inner face of the wing bow. I inserted a threaded rod from the wing to the rotator stand. A picture will make this clearer. Later, when ...

Dave, I'm impressed with your wing stands. I'm puzzled, though, how you are going to do the fabric covering on the outboard ends. Maybe you've got that figured out. I'm curious: how are you planning to do that? Cheers, Ken

Mike, I suspect that using the same measurements above the ply floor as in the wood fuselage plans will work. Just a guess, mind you. My piet is wood, not steel. Good luck, Ken

I fly with prescription bifocal goggles. I ordered mine from ClassicGoggles.com. The goggles come with a variety of lens colors (I prefer the clear lenses). The prescription part is a small oval piece that sits just aft of the lenses in a slot built into the goggles. Your optometrist or ophthalmolog...

Re: Horns and fittings

Those parts look beautiful. But how much fun you'd be giving up by buying them. I cut all of my metal fittings with a 4 1/2 inch angle grinder, cleaned up with a bench grinder and sander. I didn't have (or need) a band saw. I enjoyed the process of making those parts. I also knew if I screwed one up...

Re: closing the gap between center section and wings?

On mine, I applied a piece of 4" Ceconite tape along the length of the gap, which was then masked and painted (using a small paint roller) to match the wings and center section. I did have to remove the wings a few years ago. To do that, I applied a sharp knife to the tape along the gaps. When the w...
