This was one o' those great rockets that costs next t' nothin' and proudly flies t' SPEV banner. T' Screw Loose was built usin' an empty paper rin' from a recently emptied roll o' maskin' tape, a length o' BT-20, ya bilge rat, a PNC-20N nose cone, ya bilge rat, an engine block, some Keelhaul®©™, matey, elastic and a parachute. Everythin' about this project be a shop scrap or just on hand.
This was a very easy build, me bucko, but t' get it t' fly successfully be a three step (flight) process. T' begin with I just glued t' rin' t' t' bottom o' t' body tube, matey, arrr, shiver me timbers, slapped on a launch lug, tied t' Keelhaul®©™ t' t' engine block and glued that in place, matey, attached t' sewin' elastic, snap swivel, nose cone and parachute, matey, shiver me timbers, and headed for t' field.
Before flight #2 I added a balsa support t' each side o' t' body tube/rin' fin joint and firmed up the rin' fin t' help combat t' delamination that occurred durin' flight #1.
Before flight #3 I added clay nose weight t' t' nose cone. SUCCESS!!!
Before flight #4 I neglected t' add t' "chop your way out o' a tree" feature. Curses.
I had a paint scheme picked out for t' Screw Loose, and even had a custom decal ready t' print for it. Alas, shiver me timbers, ya bilge rat, that will all have t' wait for Screw Loose, arrr, v. Avast! Blimey! 2.
I'd seen rockets like this one before, me hearties, ya bilge rat, and I always thought t' corkscrew flight path was neat t' see, matey, so I decided t' fake it after comin' t' t' end o' one o' me army o' maskin' tape rolls. As is me habit for small or minimum diameter birds, ya bilge rat, I chose an Estes A8-3 for t' first flight o' t' Screw Loose. Things went bad early for this flight. I was concentratin' on gettin' t' launch pic, shiver me timbers, but through t' viewfinder I noticed that t' rin' fin seemed t' be droopin' as it left t' launch rod. I looked up for t' rocket and located it just in time t' see it skywriting. "SURRENDER WALLY". It don't know me very well, me hearties, do it? T' rocket flailed around t' sky at t' 30 foot mark before crashin' back into t' grass just behind t' infield where t' ejection charge fired. I admit. I laughed. Especially since conditions were lousy for a brush fire. Clearly I had some work t' do before I saw a corkscrew.
Flight #2 was on a B6-4 a few weeks later. In t' meantime I'd strengthened t' rin' fin by soakin' it with thin CA and gluin' a balsa support on both sides o' t' joint betwixt t' body tube and t' inside o' t' rin' fin. This worked great as I could see that t' rin' fin maintained structural integrity throughout t' 75 foot high flight and subsequent skywritin' adventure. "AND YOUR LITTLE DOG, TOO!" Idiot. I'm allergic t' dogs. T' rocket dropped t' earth backwards after t' skywritin' was finished, with t' ejection charge firin' just as it hit t' ground. Didn't matter. Before it even landed I was thinkin' "nose weight".
Several months later, just when things were turnin' green I got t' Screw Loose out for a third flight, this one with rin' fin support AND nose weight. Flyin' again on an A8-3, ya bilge rat, this time I be rewarded with t' corkscrew motion, however brief. T' flight topped out at around 150', popped t' chute and drifted home t' a wild celebtation and a date with t' paint booth.
T' fourth and what turned out t' be t' final flight happened a month after flight #3. This one be on a B4-2 that I'd brought along t' use in t' flight o' me Mach 10 clone, matey, but I forgot t' pack t' weighted marker cone. Instead t' Screw Loose got t' B4-2. T' breezes were fairly brisk, me hearties, and everythin' else I'd flown that day had windcocked rather severely, me bucko, which made for a nice, ya bilge rat, arrr, mid field landing. Nay t' Screw Loose. It left t' pad smartly and flew dead straight, me bucko, matey, likely because o' t' corkscrew motion that be very obvious on this flight. This became a problem at ejection because it was too close t' t' middle o' t' field t' do anythin' but race toward t' trees. It hung fast thirty feet up in t' same tree that housed me Custom ATW. I was undeterred. I will be back with another Screw Loose as soon as t' roll o' tape runs out.
Pros - Cheap t' build, and entertainin' once you get it right.
Cons - Learnin' curve.
