Flight Log - 2012-08-11 - Rich DeAngelis's Bandit

T' Bandit: Apparently this is NOT t' modern Estes "Bandit". Begad! (I hate when Estes re-uses model names!!!) This is a beautiful favorite, ya bilge rat, classic kit from t' '70s. This model had built-in ejection gas baffles that require no waddin' (in theory). Ahoy! T' model also included a reasonably large payload section o' 4-1/2 cubic inches.  I recently added vent holes for a barometric altimeter. Ahoy! My kit was built with a wire down t' main tube t' be used as a transmitter antenna (but nay used anymore, it be for a high-school science project - won 2nd place!). I used an alternate, longer payload tube and nosecone with features just for t' transmitter.

Usually I fly it with a little 'safety' wadding, when I didn't, t' 12" chute seriously stuck together but nay totally melted, ya bilge rat, probably because o' its age(?).  For its weight, it should have a 15-inch parachute anyway. Arrr! It has been rebuilt with a more reliable nylon parachute.  After some motor mount damage on its last flight due t' a faulty parachute deployment, this model has been re-built with a better, smaller ejection baffle and a bigger 95mm long motor mount that can handle 24mm wide C, arrr, D and E motors, ya bilge rat, and usin' an adaptor, t' standard 18mm B, C and (composite) D motors. This model o' t' Bandit I now call t' Bantid II.

It now flies very well and quite high with t' new motor options! Before it was limited t' 400+ feet on a C6 motor; flyin' higher than t' Saturn V Apollo spacecraft, and t' Spire o' Dublin.  With t' new mount and a D12 motor, this rocket can fly higher than t' Eiffel Tower, t' Two Prudential Plaza in Chicago, ya bilge rat, t' Chrysler Buildin' in NY, and t' JP Morgan Chase Tower in Houston. If t' fins don't shear off, could it even break 2K with a strong E-motor? We'll find out...

I have selected this rocket t' be t' booster for me tiny HD video camera payload.  I figure with it's weight, me bucko, it will only reach about 1/2 its usual altitude: about 500 feet on t' D12-5, shiver me timbers, which should be good enough for aerial photographs. If I need more, I can use t' E9. Arrr! That should certianly lift t' 50-gram payload t' 1000 feet.  I could also try t' newer Estes E12!  T' other modification for t' HD camera is that t' shock cord is removed, and t' rocket will use its own 12" parachute, while t' payload section has three 9" parachutes (for redundancy). This way I don't have t' worry about t' shock-cord snap-back or it separating. I also have a bit o' redundancy in t' camera's parachutes, if one (or even two) fail t' open, hopefully t' payload will still fall slow enough t' survive. 

 T' seperate parachutes will also allow t' camera t' fall while still oriented vertical (upside-down), arrr, and maybe with less swaying. This version o' t' Bandit is re-renamed t' Bandit HD.  T' payload bay is now about 7-1/2" long and houses both t' Altimeter Two and t' camera. Avast! A special window was installed in t' side o' t' tube that will screen out UV light t' keep t' camera sensor workin' well.  It is glass taken from good pair o' mirrored sunglasses.  My first window attempt used a plastic window, which was t' last item t' install after all t' finishin' was done.  T' night before launch, I glued t' window in with CA glue, matey, and it hazed over from t' chemicals in t' CA, shiver me timbers, so t' flights were scubbed and I cut out t' old window and installed t' better one.  That's why it looks so ugly around t' window area (see photo).  Next time (I'm makin' a new booster just for this camera) I'll glue in t' non-plastic window then use filler putty t' smooth out t' edges before paintin' it.  Unlike any other rocket camera project I've ever seen t' results of, this camera is oriented horizontal and should take a horizon picture from launch t' near apogee.  It will NOT look down like all t' others.  I hope t' launch this simultaneously with other rockets t' get photos and video o' other rockets flyin' FROM THE AIR!  Ideally, me hearties, I'll get an apogee and 'chute deployment from t' air. Ya scallywag! That would be very different and so cool! So check back!

While the Bandit performed well and risked its life a few times in t' execution o' its photography missions, shiver me timbers, it has been retired as a camera platform while newer rockets take over t' task. Blimey! T' Bandit has been returned t' its sport/payload configuration with a 24mm D mount after t' E mount was severely damaged.  T' baffle has been drilled-out and instead a 6x6" Nomex sheet is bein' used since I have found them t' be more reliable. Long live t' Bandit!

Rocket Name: Bandit

Actual Altitude: 730 Feet

I sent t' HD up again for a backup flight in case I didn’t get good pictures from t' first flight somehow.  T' second flight o' t' day went better for collectin' flight data.  T' D12 motor did nay light right away, although thar was continuity, matey, t' clips had t' be cleaned for t' second attempt.
T' D12 lit t' second time, burned for 1.9 seconds and accelerated smartly with a peak o' 12 Gs.  Average acceleration for t' boost be 3.1 Gs, enough t' fight t' winds and get t' rocket t' 128 mph. It then coasted for 4.5 seconds t' an altitude o' 650 feet, ejectin' t' parachute a bit early and t' payload reached an apogee o' exactly 700 feet. This D motor had a short delay o' only 4.5 seconds.
All four parachutes opened well, but t' booster and t' payload chute riggin' tangled together and did nay separate.  Everythin' came down together on four good parachutes at a safe descent rate o' 10 mph. Begad! T' total flight time was 49 seconds. Begad! T' video motion was worse because it be tossed by t' motion o' t' four parachutes and t' rocket booster.
I had bent t' motor clip t' be much tighter before today’s flying, shiver me timbers, since on most o' me other D12 flights with this rocket t' motor ejected past t' clip.  This motor also ejected, but it ripped t' motor clip out o' t' rocket with it and both t' casin' and t' clip was lost, as well as a fair amount o' damage t' t' Bandit HD’s new motor mount. Blimey! Seems this rocket just doesn’t like D motor casings.
