1. ### Why battery-powered aircraft will never have significant range

Roughly a factor of 4 and you'd be at the original Cri-Cri (9hp a side-twin engine) for one full size person. With currently flying electric examples. https://deankmiller.com/cri-cri-aircraft-for-sale/

Hello, Can I pick your brain about your brief time with the SQ2000? I read your posts on the Canardzone and here. I would like to hear what you learned in the process if you can spare the time. Thanks, Kenneth
3. ### Introducing AeroAcademy - Online Courses about Aerodynamics and Flight Dynamics

Doug, I'm enrolled. Thank you for sharing this. Good stuff!
4. ### Trace based simplified composite analysis. Opinions?

My last post on this thread. On my phone it looked like it was recent and on this website I can't edit my posts after a few minutes. It makes me a little crazy when I re-read my posts and it looks like a child wrote it. Sorry for my random post. I didn't mean to detract from the topic. I...

7. ### What did you do on your airplane project today?

I would love to see that database & spreadsheet, if she ever wants to share. Actually, all can be done in a database and queried any myriad of ways depending on how she built the tables. and can be so much easier to enter data. Even knowing what the Raptor project is... She’s a keeper!
8. ### Experimental Ducted Fan Aircraft Designs

Yep, meant not a ducted fan. Referring to the Fully Charged episode that I linked in my post. Electric aircraft counter rotating, not ducted. Taking "Not DF" out like that takes it out of context.
9. ### Experimental Ducted Fan Aircraft Designs

Not DF but electric aircraft with counter rotating props. This was a few years ago, so I wonder where this project is now. High power sport racer is how they describe it.

11. ### For Sale Craigslist

Thanks Bille, The Boulder VariEZE fell through. The guy wouldn’t get back to me with photos. Although that’s a nice looking LongEZ I can’t swing the purchase a finished bird. I’m going to have to die from 1000 cuts instead of one big cut purchasing a finished aircraft. I did purchase som Cozy...

13. ### Trace based simplified composite analysis. Opinions?

Just my .02 I don’t think there data holds water. Let me explain. We have the most robust out of autoclave process for destructive and non-destructive analysis carbon fiber layups according to the folks we’ve been working with the FAA. Even the same tech at the same temperature and humidity...
14. ### Trace based simplified composite analysis. Opinions?

I do PAUT (Phased array ultrasonic inspection) on carbon fiber parts for a small aircraft manufacturer. I’m very interested in what he has to say. I should be able to check it out tomorrow and get back to you. Kenneth
15. ### Ebay Today

The Velocity SE is a quick build kit. Even with that it seems like he’s asking too much for my meager budget. $26.5k. His name is Grigore and I have a different phone number than is listed on ebay if someone needs it. There is also another Velocity SE f/s in Vegas also$26.5k but much further...
