3D modeling and more tail fun

Apr 21, 2025

Work continues preparing the Skycrane for Helistorm. Spent pretty much all of yesterday doing CAD modeling of the IBFs. Also designed and printed the fore/aft gear fairings. Will be doing the aux external cargo hooks next, as well as running a whole lot of brass to simulate the Hyd lines and control tubes.

Also, added a few photos from September where I flew the crane at the annual electric event in St George, UT. At that event, I suffered an IGB gear failure on spoolup. No damage, but had to change the gears and some procedures to prevent that from happening again. After adjusting shims and redoing the tail pushrod mechanism a few times, I’m satisfied that I will have robust and precise tail control this time around.​
