12/2016 First flight with a B engine went great; I would recommend this mod. I added back the clay I took out (so I've used the entire package) and its flight was stable.

11/2016 Every flight thus far has arced over and deployed inches above the ground. A10 engines apparently are not cutting it. I've ripped out the engine mount and I am installing an 18mm mount, along with some extra nose weight. Hopefully a B engine will be enough to get this into the air.

9/2017 Windcocked into the ground on a B6-4. Not going to repair.

2022 flew with no repairs on a C6-3, went fine.
