Probably don’t need to do that much designing, Robert. If your alternator and regulator are running, voltage will be system charging voltage at both batteries. If no alternator, then you can switch to

Definitely should read Bob Nuckol’s stuff. I did so thoroughly and also had some phone discussions with him before I designed my rather complex wiring system. I run two EarthX batteries in parallel, s

If it were my wing, I would remove the damaged portion and inspect the foam, then replace with new foam of the same type, then reshape the foam and do the proper feathering of glass to effectively “re

A couple other things. On a composite aircraft there is no grounding to the airframe. This is a good thing, in my opinion, since a lot of metal plane builders get caught with noisy electronics because

I use several Amphenol “type” of conectors to make my engine wiring fully disconnect-able at the firewall. Some of these connectors (AN quality) are pricey, but they allow me to disconnect everything

That location looks like it was damaged by a glancing impact. It will require some careful repair work because it is near the high stress portion of the spar caps. Before you start, completely read an

Hi Chris, Looking at your numbers again, and in light of your question about pitch. I think for your plane -3 degrees (3 degrees nose down) is not realistic. Perhaps your arm rest is not zero wrt to t

Sounds really good, Chris. You have clearly built a nice airplane. Do you have a reduction drive on you Subaru, or is that 3200, the crank speed. About the sink rate. Keep in mind that there is a "'mi

You got it now, Troy. The envelope was expanded for the LS1 canard, and I am guessing that you have the GU canard, so strictly speaking you will want to use your blue outline, but there is probably so

All the material that you need is in a folder in the files section of the group. If you do not find what you are looking for, I have an interactive spreadsheet that is much more extensive that can be

Thanks. The picture will still help, but that location is one you need to be sure about. The closer to the wing root, the more bending stress on the wing, so the more critical the repair. Cheers, Jay

Please send another photo, so we can see where this is located on the wing (ie. zoom out). Some places you repair can be very critical and others, not so much, so we need to see where this is located.

Hi Robert, I think you can install it where you want it vertically, It would only be a matter of rebuilding or adjusting the vertical pushrods to suit your choice of vertical position of the donut. Al

Looking very good Robert. Only one comment from me. That seatback bulkhead joining the leading edge of the wing and closing out your over-wing storage “shelf” is the only roll over protection you have

Thanks for the report, Chris. I was wondering if you had dug out yet, and it appears you have. Sounds like you have a very good handling plane. Cheers, Jay

Hi All, At the Spring Fling, I shared a short story over lunch with Nathan Peck concerning the violent demise of the Scaled Composites 80% scale Starship prototype. Just by coincidence, I just happene

Hi All, I promised Jerry and Sam H that I would send a link to the details on how to find the LED strip/ribbon lighting that I had strung into my area forward of the cockpit and beneath my panel. I fi

The tailwheel guys will pipe up soon, but I will tell you now that the tail spring will break where the local load concentration is the highest. If you have a stiff sleave and you put it over the soft

Starting to get that way. I have made two runs from western Colorado to Enid, One to Decorah, one to Oshkosh and now one to Terre Haute. We are becoming one…. Cheers, Jay

Great to see you again, Mike. You need to do what I did and sell that airplane (Bonanza), so you have incentive to “git-er-done” 😉. Just kidding, that Bonanza is a very comfortable and efficient ride!
