Ha-ha! Touche! Yes, of course you are right. Not owning a -18°C freezer, I was thinking of room temperature cure low-vacuum consolidation to achieve ~50% resin content, not prepreg…. I can’t wait to s

Flax is inferior to highly-crystalline cellulose fiber for exactly the reasons mentioned below. Highly-crystalline cellulose fiber is nearly equivalent to E-glass in all respects except weight -- glas

Rob, Fuselage torsional stiffness is low until the wing and canard are installed. Eugen, Be sure to download the entire SuperQuickie Conversion report, not just the one picture that I sent earlier. ht

Vern, I appreciate your enthusiasm but: Carbon and titanium and prohibitions – oh, my! These planes are made from super-cheap insulation materials sourced from Home Depot and a second-hand generator m

Eugen, Yes, you understand the plans correctly with regard to the BID. You really should have a PDF of the original plans for reference; the OCR version on the Quickheads site is very well done but so

“I did not catch up that point yet.” I’m not sure I understand your reply. To clarify my point: plans page 4-3 comes before plans chapter 7 so glassing the firewall should have been completed before f

Eugen, aren’t you supposed to have 1 ply BID on each side of the firewall before fuselage assembly? See plans page 4-3.

Get on the Facebook Quickie group and look up Richard Celata. He is making components available meaning that you’ll be able to purchase new and build from scratch. Also get the plans and newsletters;

I might be interested. What’s your location?

Garry Legare built the boxy one without QAC knowledge or assistance. Then he showed up at the factory and they decided he had a good idea. Legare kept worldwide design and distribution rights, QAC got

Eugen, It appears that you machined a 45 degree bevel on the inside contouring of your fuselage sides and bottom. The section A-A you refer to shows a much more shallow bevel. You MAY encounter proble

No, you are not correct. Yes; yes; no. Read the plans again. In your annotations of the picture from the plans, you have misidentified the location of the main wing. The main wing resides in the bay j

Hi Jim, Merry Christmas to you, and to all on the Q-List! I retired from ATC four years ago, then successfully pursued my dream of being an airline pilot for three and a half years before the coronavi

So you’re taxiing downwind at idle at 15 kts. with a tailwind gusting 18-26 kts. from 20 degrees to the right off your tail. Basically, your vertical stabilizer/rudder is at zero airspeed gusting to -

Cody, Ask for Dow Styrofoam XPS PIB at your local industrial insulation supplier. Or call your local taxidermist and ask where he gets his foam. I got nine foot long FB blocks that were 10”x20” from a

Corbin, It looks to me like you could just install the mount as assembled at the factory, but put it on the left side of the case split line under the nuts instead of under the heads of the case bolts

Corbin, I think the 5.00 x 5 tire size is half your trouble. The 4.00 x 5 would be narrower yielding more clearance from sidewall to caliper. David J. Gall
