    Harlow PJC-4 on Facebook Market place $9,500

    They actually built 11 of them. I had the pleasure of a flight in Mel Cassidy’s pjc-2 many years ago. It’s a very nice airplane…For the right restorer it might be a worthwhile project.

    Very low aspect ratio planes?

    Matthew: A few thoughts for you: First, we normally take off at a speed significantly above stall speed in order to have positive rate of climb and stall margin for gusts. Typically lift-off speed is about 1.2 x stall speed, so Cl is about 70% of Clmax at that point. The issue about CLmax for...

    Lots of info here: Including my BW 05 02 09 section designed years ago for plank RC models

    Flying wing as cheap and simple option for basic fun flying.

    I'm not suggesting any particular configuration... Just pointing out a source of a lot of good experimental data. You can get a lot of insight from reading some of the reports.

    Flying wing as cheap and simple option for basic fun flying.

    Lots of good info has been published, particularly here: Search on "gothic wing" or "ogee"

    1994: Base leg to KOSH RWY 9 viewed from the cockpit of N117WD. Early July arrival so field is still empty.

    Still working on the design of the 2-seater. Hope to start building before too long.

    Original airplane was aluminum just like the Oregon build. The outer mold line shape is the same as the original airplane. Its not scaled up or down. There have been detail updates and changes but the overall approach is the same as N117WD. The Facetmobile itself was always built to be...

    Very low aspect ratio planes?

    Fins on Talon Topper are permanently fixed. You may have found a video of a minor mishap but I'm not familiar with it. The fins on both airplanes are positioned so the fin structure can hook into the mounts to the main hull at a point near the fin aerodynamic center to minimize moments on the...

    Very low aspect ratio planes?

    Berridos's last post, at least as it relates to Facetmobile follows the sadly-common trend on HBA of someone who has no first-hand knowledge making authoritative-sounding statements that are completely wrong. When its just people talking "general principles" I generally refrain from jumping in...
