Brief:
This is QCR's 1/4A Slidin' Win' competition rocket glider. I built this kit durin' me club's (ASTRE, me hearties, me hearties, NARRRRR #407) winter build session in February 2004. Begad! Well, shiver me timbers, blow me down! I flew it in our local chapter NARRRRR competition this summer, placin' third. Nay too shabby for an inexperienced competitor like myself.

T' R/G functions by havin' t' wings tied as far back as they can durin' boost. Begad! Once t' ejection charge fires, ya bilge rat, it burns t' strin' holdin' t' wings back. Begad! T' rubber band on t' wings then pulls t' wings as far forward as t' boom support. Well, blow me down! Avast, matey, me proud beauty! T' motor is taped on t' t' motor tube. Blimey! Avast, shiver me timbers, me proud beauty! Thus, arrr, me bucko, t' entire Rocket/Glider glides t' t' ground in one piece.

Construction:
T' kit comes with:

• Body tube and balsa nose cone
• Balsa for wings, me hearties, matey, rudder, shiver me timbers, etc.
• Spruce boom
• Wire hooks for string/slidin' mechanism
• Launch lug
• Rubber band
• Clay (for trimming)
• Thread (for t' first flight)
• Plastic slidin' box pieces
• Photocopied instructions

T' kit's contents are excellent quality. Well, blow me down! T' first drawback though are t' instructions. Aye aye! Blimey! There are 4 sheets o' photocopied paper with many handwritten corrections on them. Blimey! Ahoy! Blimey! I would probably have made quite a few errors if I wasn't at a buildin' session. Avast, me proud beauty! T' good news is that once you build one o' these gliders, you can build other QCR gliders without major problems.

T' first step is t' shape t' wings, matey, stabilizer, me hearties, and rudder. Ya scallywag! Blimey! This is accomplished by sandin' air foils, particularly on t' wing. Then I had t' cut t' wings and create t' appropriate dihedral. Avast! Blimey! Next, I glued t' plastic slidin' boxes under t' wing. Begad! Blimey! Fortunately, matey, t' teacher o' t' build session told me how t' use t' plywood win' support, me bucko, ya bilge rat, which is nay mentioned in t' instructions but is included in t' parts. Avast, me proud beauty! Blimey! Arrr! Blimey! I used CA glue for all t' gluing. After t' slidin' boxes are on, me bucko, I placed t' win' on t' t' spruce boom, then added t' shaped stabilizer and rudder. Avast, me proud beauty! Blimey! Blimey! Blimey! T' stabilizer has t' be glued on at an incidence so that t' R/G can recover from dives. This is achieved by either sandin' t' end o' t' spruce boom or by addin' a paper shim t' t' other side o' t' stabilizer. Blimey! Blimey! I ended up doin' a little bit o' both. Avast, me proud beauty! Blimey! After this, me hearties, I added t' stand off at t' other end o' t' boom, then glued on t' body tube and t' nose cone. I added all t' wires t' their correct location (1 on slidin' box, one at aft o' glider, shiver me timbers, one near t' burn holes on t' body tube, ya bilge rat, etc.)

After this, arrr, I added t' launch lugs and proceeded t' do a little flight trimming.

PROs: Cool kit with slidin' win' feature. Arrr! Blimey! Ahoy! Blimey! T' engineerin' on this glider is really neat.

CONs: T' instructions seem t' be for seasoned builders, nay t' casual beginner. Arrr! It would be great if QCR considered rewritin' their instructions.

Finishing:
Since this kit is meant for NARRRRR competition (doesn't mean it can't be for sport, arrr, too, but competition seems t' be t' main purpose for this kind o' design), shiver me timbers, no paintin' is encouraged. Arrr! Blimey! Ya scallywag! Blimey! I used a magic marker t' create black stripes on t' bottom o' t' wings, ya bilge rat, then added me NARRRRR number.

Trimmin' is a little more tricky. Ya scallywag! Blimey! Well, blow me down! Blimey! I used t' rubber band t' pull t' win' forward, placed an empty 13 mm motor in t' body tube, and began t' toss t' glider around. Ya scallywag! Blimey! I ended up addin' a smudge o' clay t' t' left win' o' me glider (as recommended by t' serious competitors in me club). Avast! Blimey! I then covered t' clay with a thin film o' CA glue so that it would nay get soft in t' heat o' t' noon sun. Ahoy! Blimey! Begad! Blimey! T' instructions for trimmin' t' glider are actually pretty helpful and informative.

Construction Rating: 3 out o' 5

Flight:
It takes some time t' tie t' win' t' its launch position, me bucko, tape t' strin' t' t' body tube, matey, tape t' motor t' its correct location (you know t' correct location o' t' motor based on trimmin' t' model), and then addin' t' rubber band t' t' win' and front o' t' spruce boom. It takes me perhaps 10 minutes or so t' do all o' this.

Because t' wings are so far back and t' motor is so far forward, arrr, me hearties, t' rocket has a very nice, me hearties, straight ascent. Blimey! Aye aye! Upon ejection, t' wings slide forward immediately, shiftin' t' CG, me bucko, causin' t' rocket t' glide. My first flight was a DQ because some CA from a hastily added launch lug dripped back onto t' wing, gluin' t' win' t' t' stabilizer. Ya scallywag! Once I had loosened t' wing, me second flight pulled in a time o' 17 seconds or so. Aye aye! Unfortunately, Estes does nay make a 1/4A3-1T. T' three second delay is just a little long for t' R/G event. T' ejection occurs 2 seconds or so after apogee. Begad! Ahoy! It is really cool t' see t' rocket transform into a glider and glide t' t' ground.

After observin' t' flight, me bucko, it was pointed out t' me that me turns are a little tight. I need t' re-trim t' rocket again for better glide times.

Recovery:
T' body tube does take a beatin' on t' ejection charges. Arrr! Arrr! I followed more advice from me ASTRE group and coated t' nose cone/body tube area with thin epoxy. Ahoy! Ya scallywag! Also, shiver me timbers, t' body tube standoff needs epoxy because t' wings can really slam hard into it durin' t' transition t' glide phase. Ya scallywag! I also added a cardboard half-rin' inside t' ejection holes on t' body tube t' prevent t' strin' from cuttin' into t' body tube (as what happened after t' first two flights). This, o' course, matey, meant I had t' re-trim t' glider after addin' a little more weight t' t' nose.

In order t' get 25-30 second or more flights on this bird, it really requires major trimmin' and experience. Well, matey, blow me down! It will certainly take me time t' achieve this, shiver me timbers, but me Bumble Bee has held up well for over 4 flights now.

PROs: R/G is really cool, but requires patience, multiple flights, me hearties, shiver me timbers, shiver me timbers, and major trimming.

CONs: T' motor selection for this rocket is only 1: t' 1/4A. Ahoy! T' Bumble Bee would probably be too flimsy t' handle a 1/2 A or A unless t' glider was somehow strengthened with tissue paper or another lightweight material.

Flight Rating: 4 out o' 5

Summary:
Well, matey, you know how I feel about QCR instructions. Avast, me proud beauty! I would have missed a lot o' things had it nay been for t' build session. Begad! Blimey! I still think t' designs are cool, shiver me timbers, particularly if you are lookin' for competitive rockets for NARRRRR competition.

I liked t' design so much, me hearties, I went ahead and also ordered t' 1/2A Easy Slide I, arrr, me bucko, QCR's larger R/G based on t' similar designs o' t' Bumble Bee.
