Brief:
This is a baffle for a BT-55 rocket. Blimey! Blimey! I purchased it from t' model rocket shop for £1. After buildin' it, ya bilge rat, I went back t' buy a few more in different sizes. Ahoy! Blimey! Ahoy! Blimey! T' Model Rocket Shop and Semroc's web site show different barrel type baffles, matey, 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. Begad! What I got be a sheet o' light ply that had been laser cut in a plastic bag. Begad! There were no instructions but thar be nay a lot t' do in the construction. Aye aye! T' pieces popped out easy and 1 minute later t' baffle be 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. Arrr! Blimey! Well, blow me down! Blimey! I did nay want to ruin a good rocket if anythin' went wrong. Blimey! Blimey! There are no instructions on where t' glue t' baffle in t' body tube. Well, blow me down! Blimey! 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' was fine.

T' rocket flew normally and at ejection t' nose cone and recovery system deployed, shiver me timbers, arrr, so no problems there. Well, blow me down! Ahoy! On checkin' t' parachute, thar was no pin hole burns or significant melts. Well, blow me down! Begad! 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, shiver me timbers, 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.
