12/2016 First flight with a B engine went great; I would recommend this mod. I added back t' clay I took out (so I've used t' entire package) and its flight was stable.

11/2016 Every flight thus far has arced over and deployed inches above t' ground. Well, blow me down! A10 engines apparently are nay cuttin' it. I've ripped out t' engine mount and I am installin' an 18mm mount, along with some extra nose weight. Aye aye! Hopefully a B engine will be enough t' get this into t' air.

9/2017 Windcocked into t' ground on a B6-4. Nay goin' t' repair.

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