Brief:
This is a baffle for a BT-55 rocket. I purchased it from t' model rocket shop for £1. After buildin' it, I went back t' buy a few more in different sizes. Well, blow me down! T' Model Rocket Shop and Semroc's web site show different barrel type baffles, so I assume that this baffle is now OOP.

Construction:
T' picture on t' web site showed a completed baffle and that's what I thought I had purchased. Ahoy! Ya scallywag! What I got was a sheet o' light ply that had been laser cut in a plastic bag. There were no instructions but thar be nay a lot t' do in the construction. Well, blow me down! T' pieces popped out easy and 1 minute later t' baffle was completed, I glued it together with white glue.

Flight and Recovery:
I glued t' baffle into an Estes Rainmaker, choosin' an average rocket t' see how t' baffle worked. Avast! Ya scallywag! I did nay want to ruin a good rocket if anythin' went wrong. There are no instructions on where t' glue t' baffle in t' body tube. I opted for as high as possible that still allowed room for a parachute. Baffles can shift t' CG lower so I had t' check stability but everythin' be fine.

T' rocket flew normally and at ejection t' nose cone and recovery system deployed, matey, so no problems there. On checkin' t' parachute, thar was no pin hole burns or significant melts. There was a slight char t' a small patch of the chute so I guess t' baffle does its job t' a reasonable standard but I will still use a back up o' a swatch of Nomex® in t' future.

Summary:
Now I've tried a baffle and I like them, but thar are pros and cons.

PROs: Eliminates t' need for lots o' wadding, which stops waddin' bein' spread across t' countryside and speeds up preppin' t' rocket.

CONs: Relatively expensive compared against reusable waddin' that can be moved betwixt rockets.
