I really love seeing the result of someone building one of my kits and this is certainly no exception! I would like keep the record straight, though. The original base-button/foot-socket provision does allow the rocket to stay in position on the base and still be removable. The builder has the option of gluing the feet to the base or to leave them unglued.
The purpose of this feature is to keep the weight of the rocket from being borne by the struts that go between the fuselage and the legs. If there was no provision for this, there is a likelihood the legs would tend to splay outward over time. The added benefit is the rocket stays in place without being permanently attached.
I do not mention this to be critical this build. I support any decisions made by my clients to make modifications to the kits they have purchased from me such that if something needs to be replaced because of a modification that didn't work out, I supply replacements free of charge. My concern is that other builders may read this and think the mastering of this kit overlooked a way for the rocket to register to the base and still be removed.
I really look forward to seeing the conclusion of this build!!
