Re: Quickie Q1 Canard and wing foam cut

That’s one more coincidence. I knew Leeon Davis and his family in Midland TX, and Stanley Davis, Leeon’s brother, is the one who taught me to fly. I love that little boxy DA-2. It got more sleek as it evolved into the DA-5, which Leeon had plans get manufactured as a trainer, but alas, that never happened.  You should come to Enid this weekend, we probably would have a lot to talk about.

 

Cheers,

Jay

I wasn’t aware of that. I also have a Davis DA-2A.

Wow Bob,

 

You and Keith W. are like twins! Each of you with a T-18 and a Q1. What are the odds of that, I wonder?

 

Cheers,

Jay

I'm in Santa Rosa, CA but we are hoping to move shortly to escape the fires (we lost our home in 2017) so airplane progress is halting at best. Hopefully we'll end up near San Luis Obispo on the central coast where I have a flying job (I commute in my Thorp T-18).

Thanks! I’m using a no-name 680cc aluminum air-cooled V2 diesel to which I am adding a tiny turbocharger and intercooler. What’s changed since you looked is probably direct injection. Engine weight is around 50kg. I’m adding a belt drive from Ace Redrives in India. It’s 1:1 because I don’t need a slower prop but I do need to raise the thrust line and to isolate the prop loads from the mystery metal Chinese crankshaft. I’m probably a year from flying, by which time I will have replaced most of the airframe with vacuum-bagged pre-preg. It’s not carbon or glass — it’s flax fiber, which fits right between e-glass and s-glass in performance, with a little Coremat added for stiffness.

What diesel engine are you considering?  I looked at the V-twin Chinese diesels more than a decade ago and discarded the idea as not practical.
There are some interesting marine 2 stroke diesel development projects nearing market introduction that may provide some of us with a 100LL option.

Look up Alan Thayer (sp) in the archives.  He had an LS-1 canard designed using Graphlite rods.Attached is a *.ZIP file of some of his work.  Graphlite is no longer a practical source of carbon rods for us as they are quite unwilling to sell rolled lengths of material.  The Chinese suppliers are willing and at a considerable savings in cost.  Preliminary tests have indicated the quality/strength is as good as the US sourced material.
