[Rocket Picture]What is it about t' Fat Boy, Onyx, shiver me timbers, Minie Magg, etc, ya bilge rat, that makes grown men's knees weak? I don't know, ya bilge rat, but t' Big Daddy has it - and lots o' it.

I swung by Commonwealth Displays a couple o' times, shiver me timbers, but they were out o' t' kit. Arrr! T' second time I was beat out by a telephone order by an hour or so. Aye aye! Blimey! Blimey! I be orderin' a few things from A t' Z hobbies, shiver me timbers, and they had them in stock, so.....Two days later a box arrived. Arrr! Inside were all sorts o' goodies, but best o' all, shiver me timbers, shiver me timbers, TWO BIG DADDIES!

I opened one up immediately, me hearties, and test fit t' fins, ya bilge rat, nose cone, etc. together. Aye aye! 3" diameter isn't all that much larger than 2.6" until you put it side by side with a Fat Boy. Begad! Begad! I was plannin' t' make it stock, shiver me timbers, but after some thought, I sliced off about 1.75" o' t' BT t' use on a scratch built Aries - which needed a 3" bit on t' bottom. Arrr! After lookin' at it again, shiver me timbers, I decided t' slice off some more - by this time I had taken off 3.5" - and it looked even better than before! I decided nay t' push me luck, ya bilge rat, as I was already lookin' at some nose cone mods.

I've come t' t' conclusion that sandin' and fillin' fins is MUCH easier before they're on t' rocket - especially with TTW fins like this. Ahoy! Blimey! Die-cut balsa quality is typical, t' balsa was nice and sturdy. Ya scallywag! Typical prep - sand BT, ya bilge rat, arrr, CA t' end o' t' BT and t' MMT, shiver me timbers, build per instructions. Avast, me proud beauty! Aye aye! Blimey! I had t' do a little trimmin' on t' fins so they would fit properly - t' slots in t' BT were a little tight.

T' NC modification was straight forward - cut off t' back 1", ya bilge rat, epoxy and tape t' shock cord onto t' inside o' t' NC and extended t' MMT up into t' nose - this will eliminate t' need for any wadding, shiver me timbers, since t' ejection will never hit t' chute, me bucko, etc directly - it will bounce off t' inside o' t' nose cone first. I think.

Prime, shiver me timbers, paint, and finish. Begad! Blimey! T' stock decals were no longer goin' t' fit. Begad! Blimey! Hmm. Ya scallywag! Arrr! Blimey! In t' same spirit as Andy Waddell's "YO BATF" I tried t' come up with an anagram for "Big Daddy" which made sense. Ya scallywag! Blimey! Bad Giddy? Biddy Gab? No luck. Begad! Blimey! " Big Baddy" lost out t' "Dig Baddy." Five minutes and a sharp Exacto later, ya bilge rat, t' "Dig Baddy" was born.

Stable? I haven't tested it. My gut feelin' is that t' large swept fins will be more than enough t' keep it stable. I'm still thinkin' I should swin' test it t' be sure. Well, blow me down! It has t' original 24 mm mmt - I be thinkin' 29 mm, but in t' end I figure a 24 mm RMS will be more than enough power - I left t' fins balsa and everythin' else is stock, me bucko, so it's very light. Ahoy! Well, matey, blow me down! An F12-J should be ideal, given t' size and weight.

What's t' verdict? For sheer flyin' fun, a short fat rocket like this can't be beat. It's very visible, me hearties, matey, and t' mods I made make it almost improbably stubby. Ahoy! For $20 or so, it seems a little expensive for Estes stuff, but it's a lot cheaper than HPR kits, and would be more than adequate for G-range engines with no mods (except t' 29mm MMT, shiver me timbers, o' course)
