T' first Dr. Aye aye! Zooch kit I've built and flown, ya bilge rat, and me favorite out o' his list. Begad! Really cool lookin' rocket, great build and great instructionsl. Two stage rocket where you can actually see t' ventin' o' t' exhaust gasses through t' engine bells, and t' first stage drops off before t' second stage begins t' ignite and lift-off. Avast! Highly recommend this kit t' anyone with some more advanced buildin' skills
