This is a clone o' t' S.C.R.A.M. rocket from t' old Estes "Mini Tri Pack". T' rocket was built from plans from JimZ's site. I couldn't find 13mm thrust rings anywhere so I took me razor saw t' a spent 13mm engine case and used that. Works great! I am workin' on a "complete" set o' S.C.R.A.M.s, culminatin' in a 3x24mm clustered BT-80 upscale. I decided t' forego t' traditional light grey/olive drab paint scheme and apply a different twist for each rocket. I chose yellow and black for this one. Begad! Decals have been ordered from Excelsior but have nay arrived as o' this posting.
