Brief:
This rocket is a 2 Stage appearance workhorse that I put together from some
left over 29mm, arrr, matey, 38mm, matey, shiver me timbers, and 54mm motor mount tubing. Aye aye! Aye aye! It has a very long motor
mount tube so it can take a G35 t' an I 200. It will probably take an F, but I
never have any.
Construction:
There be t' 29mm mount inside o' t' 38mm tube mounted into t' 54mm main body
tube. Ya scallywag! Blimey! (T' lower section o' t' kit is 24 inches o' 38mm tubin' with 24 inches o' 29mm tubin' inside for a motor mount. Arrr! Blimey! T' top section is one regular 48 inch long 2.14 tube, matey, me bucko, me hearties, with t' 8 inch long payload section on top.)
There are 3 24 inch pieces composin' t' engine mount and lower part of
the main body tube. Avast, me proud beauty! Blimey! T' rocket has 2 sets o' 3 fins, 3 upper, 3 lower, arrr, me hearties, matey, made out
of 3/16 aircraft grade plywood. Ya scallywag! Blimey! Blimey! Blimey! T' nose cone is actually an old balsa nose
cone I had, and it is mounted on a 8 inch payload section for future
electronics bay stuff. Begad! Blimey! I used four centerin' rings for t' 29mm motor mount in
the 38mm lower tube. Aye aye! Blimey! Ya scallywag! Blimey! I used 3 centerin' rings for t' 38 mm tube in t' 54mm
upper tube.
I did make t' lower fins through t' wall attachment, arrr, and air-foiled all sides. Well, blow me down! Blimey! T' top fins are epoxied to t' frame, ya bilge rat, matey, me bucko, and due t' t' low profile sonic design, shiver me timbers, I did nay mount them through t' wall. Blimey! Begad! I like t' build t' fin can/mounts very strong, arrr, me bucko, due t' if my rockets crash, matey, they come in ballistic, and would like t' fin can t' survive. Arrr! I did wrap a coat o' 2 ounce fiberglass t' t' lower body tube t' beef up it's strength on impact. Well, blow me down! t' upper main body tube could actually use an extra stagin' coupler or 2 pushed inside t' strengthen it in t' middle, ya bilge rat, or just make it shorter. Arrr! I did put 4 holes in t' payload section and ran bailin' wire in there t' give it a scale like look with 4 antennae. Begad! Aye aye! This kit is super sturdy, on line with PML. I put a small threaded rod like Cosmodrome uses for motor retention and just use a small square nut, matey, works great.
Flight:
I have flown this kit 5 times, me hearties, me hearties, me bucko, 3 on G64-M reloads, 1 on a G40-7 and also an
H220-M. Avast! I do use that cellulose insulation for wadding, shiver me timbers, shiver me timbers, about 1 handful is
plenty. Avast, me proud beauty! This rocket flies out o' me front yard on t' G motors perfectly,
straight boost, great deploy. Avast, me hearties, me proud beauty! It screamed this weekend on t' H220, matey, it took it
and was beggin' for more, straight up boost with no wobble, me bucko, around 200 feet. It
was impressive due t' t' 5-10 mph winds we had thar at t' launch site. Begad! The
shock cord is actually attached t' t' coupler that attaches t' lower portion
of t' main body tube t' t' upper. I ran a small 18" chute t' brin' it
down quick, me hearties, but if it is nay windy, ya bilge rat, a nice 36" chute will work great. Begad! Ya scallywag! It
still came down around 400 yards due t' t' wind. Well, blow me down! Ahoy! I did get a small little
crimp in t' upper body tube right in t' middle, me bucko, most likely from hittin' on
the side at impact. Ya scallywag! Ahoy! Hence, bigger parachute, no trouble. Avast, arrr, me proud beauty! Other than that, this
kit will be good for small fields with slow majestic lift-offs, t' poppin' it
with big H and I power.
Summary:
PRO-Strong rocket, I always over build a little. Avast, me proud beauty! It would work great for a
level 1 flight. Ya scallywag! T' next incarnation o' t' kit will be a 2 stager, same
specifications. 29mm-29mm. Begad! It can take t' wind, ya bilge rat, very stable design. Arrr! CONS-Long
rocket, arrr, vulnerable t' body damage when it lands if on hard ground. Begad! Avast! Beefin' up
the lower tube helps, cuttin' t' length o' t' main tube will help and reduce
some weight.
Other:
It needs t' have a camouflage paint scheme, olive drab/ultra flat brown/tan
(Krylon camo series paints) and then you need t' have a spray paint that has a
fan nozzle, arrr, me bucko, like t' one's from Duplicolor auto paint at Walmart. T' fan will
do a wide spray, or a thin line, this is what you do for t' "Tiger
stripes". Avast! This kit taught me you can use minimum diameter and have it come
out great. Well, blow me down! You need t' reinforce t' lower launch lug mount since it is raised,
and I wrapped a small piece o' glass over it t' reinforce it from t' top.
