Really similar to the ROTS jetpack troopers winged jetpack, usable with a SA Legacy fig with very little modding.
And I liked the BF2 Clone packs 501st Jetpack troopers jetpack also, although it took more to mod that to fit and look correctly.
Both of the mentioned fig were SORELY lacking in the articulation areas, so making acceptable versions has been high on my list of things to do in larger numbers.
And its not out of my skill set yet. I just hate to ruin a perfectly good toy
...
that is why I just think of it as IMPROVING a good toy
.
