That sounds about right. I have two rockets built on 3" OD tubing, one which should be much heavier than yours and goes to 4k on a full I, and one which should be somewhat heavier and goes to 3k on an I200. My mind sim was therefore guessing 4k or so on an I200. With dual deploy it shouldn't go far enough in reasonable winds not to be visible under main, but there's a lot of sky to search if it were to get lost in the haze on the way up.
But I bet with an H115DM, or any RMS 29/180 H, or one of the higher thrust Pro29-3G H motors, people could cert on your kit all day long on a busy field with plenty of spotters.
