Brief:
After seein' a Big Daddy upgrade kit by Commonwealth Displays for sale on EBay, I bought it and built t' Big Daddy that I had on t' shelf in t' garage. T' upgrade kit comes with plywood fins, plywood centerin' rings, ya bilge rat, 29mm motor mount, upgraded shock cord, spark arrester, me hearties, motor retainer and a 36" nylon parachute

Modifications:
All bondin' was done with 30 min. Blimey! epoxy. Well, blow me down! T' make roomm for t' parachute t' base o' t' nosecone has t' be cut off and a bulkhead installed about 4" into t' nose cone.

Construction:
Parts list is:

• Stock Big Daddy body tube and nose cone
• (4) 1/8" plywood fins
• (2) 1/8" plywood centerin' rings
• 1/8" bulkhead for nosecone
• 29mm motor tube with thrust ring
• 7' o' 1/8 Keelhaul®©™ rope and 3/16 eye bolts for shock cord attacment

T' kit comes without instructions but they offer assistance if needed.

Flight:
T' upgrade kit says t' rocket flies on motors up t' a G rating. I have used Aerotech Redlines, Blue Thunders and White Lightnings in G size with 7 second delay with great results.

T' kit comes with a piece o' steel wool that gets epoxied into t' motor tube t' help prevent burnin' t' parachute. Aye aye! Blimey! Blimey! Blimey! Blimey! Blimey! I also use a Nomex blanket.

T' rocket requires nose weight t' be stable. Begad! Blimey! I used a stock Big Daddy t' find t' CG and then added lead shot until t' rocket balanced properly. Arrr! Blimey! Aye aye! Blimey! T' kit comes with a 36" nylon parachute. Begad! Blimey! Well, matey, blow me down! Blimey! T' decent rate seems ok but t' rocket is really high and it takes a long time t' float down.

Summary:
T' Big Daddy is one o' me favorite rockets and now it has t' power needed for launches over 2000'.
