I developed an interest in the Estes E2X and its fin unit not only as a practical beginner's rocket, but also as a source of parts for experiments. I was able to purchase several kits at a discount. Here, I have built this model with a payload compartment capable of carrying my altimeter.
I added a 4.5" tube to the fin unit, installing a Qualman cross baffle and shock cord anchor here. Then came the kit tube with plenty of room for wadding, line and a big streamer. Atop that sits the 4.5" payload compartment which ejects together with the cone and streamer. The cone is attached with tape to facilitate removal of the payload (altimeter). The rocket weights 2.83 oz. complete with motor, streamer and tape. Overall length is now 21".
