  1. What airfoils could you use for high speed prop canard? Re ~ 5mill The NLF airfoils look pretty sweet, perhaps it could be held laminar on a quickie wing (nice and thin)...? I see the Lancair 360 uses NLF but sheesh, that thing hooks along at 200knots. I wonder how laminar it is here The OG clark Y airfoil (not the flat one) looks like a good place to start, or Eppler. Some neat info from Q-talk back in the day (GU, LS1, Roncz, Mike Shuck) Man this could take all year, pitching moment and stall characteristics, and probably a dozen other things all considered
  2. Excuse my ignorance, but that GU canard you are using, with only one strip of carbon for the spar, does that mean that the skin also is used for bending moment? I understand that the LS1 canard can be used for the Q200 and the Q1, but you need a round carbon fibre spar that is hard to come by. The Australian person who used to make it on Quickheads is likely gone on to other things...
  3. Does anyone know where we can get accurate measurements for the Q1? I bought the $99 pack but didn't realize that this just has the foam cutouts. How you built that 3D model with exact measurements of the quickie is a mystery
  4. The hardest thing with 3D printing is the quality control for sure. That and borrowing a $200k machine that has the desired 700mm bed size. I like what the guys at Darkaero have done, their honeycomb CF construction technique is CNC centric which is all that guys like me have at hand. There may not be much weight saving between GF and CF when the OG plane is a feather at 110kg.
  5. Hi guys, Thought I'd take the small step and join the forum, I purchased the Q1 plans mainly to check it out and see if it can be built by other means. In Australia its hard finding OG kits here, so I may look at a carbon composite aircraft, or maybe even 3D printing with CCF. Baby steps at the moment, I ideally would have liked to purchase a kit locally because I aim to make it electric. Anyway, hope to run into anyone else who is building down under and share some info along the way!! Kind regards, Josh
  6. Noice!!! So cool to see your progress. Keep up the good work
